OK u need to specify which method u used, i used this one http://xdaforums.com/showpost.php?p=10725793&postcount=119 , the only problem i was having was mounting sdcard on the android build, problem was that when i copied the wp7 partition to my sdcard i changed to type "logical" leave it as it is "primary".

Just test it and i still have the unlock and just deployed an emulator to prove it was unlock, also make sure u dont do any microsoft updates, i did it and lost my unlock so after uninstalling the updates i was able to unlock, not sure which update is but to make sure just turn it off, also in wp7 go to "settings", "applications", "music+videos" and turn off the "connect with zune" this will prevent from downloading updates from zube to wp7 as this maybe cause to lose your unlock, not really sure but by doing this and not updating microsoft, i still have my unlock, even after dual booting android :), give it a try and keep us informed :)
[HD2 Android SD Development] gitanojr:
well actually your wp7 partition needs to be at the end, and the fat32 at the beginning otherwise your pc wont detect your sd card, just make sure when u copy your wp7 to your bigger sd card leave it as "primary" of course this is if u want to follow this procedure http://xdaforums.com/showpost.php?p=10725793&postcount=119 , havent tried hyellow method yet :p, but f course i will and will post back ;)
[HD2 Android SD Development] tuskooo:
So leaving the WP7 partition 'primary' solved it? I'm suffering from andoird not seeing the sd card too.
[HD2 Android SD Development] MettlerNikola:
+1
[HD2 Android SD Development] gitanojr:
Pretty much, i tested myself and is working for me :), also maybe people ar having problems with zune detecting wp7 because of this, not sure but is worth the try :p
[HD2 Android SD Development] tuskooo:
I'm trying it right now...but not with the linked method first, I hope it works this way too.

Edit: yeah, this was the key to the solution.
[HD2 Android SD Development] gitanojr:
im about to try a different sd build :), to see if stills mounting the sd card :/

Edit: Yep it did work now i have two android builds on sd, mdj Froyo hd v4.6 and nexushd2 v1.8 and both mounting the sdcard ;)
[HD2 Android SD Development] georo:
Everything was working fine with your method and now I was able to unlocked and install apps and also MDJ_FroYo_HD_v._4.6_MDJ_S78.0 work perfect.

I still have one problem as in the picture bellow I have only a little space remaning on my card or whatever Zune is looking at. How can I fix that.

I have 8gb for WP7 and the rest to 16 for android.

Thank you guys for all your help and if I have time I will make a video of this.
[HD2 Android SD Development] darrengladysz:
From your pictures it seems you did something wrong as wp7 did not set up using your sd card. You should have a few gb there and not only 50mb.

Try again.
[HD2 Android SD Development] kinga33:
on my Pc running windows 7 profesional 32 bit easus does not see SD Card.Anyone ele has this problem
[HD2 Android SD Development] georo:
Yes you right I follow this steps "1. Set up your WP7 installation with your desired SD card. After all is set up, go to the about screen and reset your device. It asks you to confirm it two times, so at the second confirmation, pull out the sd card quickly and confirm the reset immediately.

Leave it on the MAGLDR screen and continue to step two (make sure the magldr is always shown at boot)"

The thing is every time I put the card back after partitioning and continue with the setup the phone go to "Let's started " and reformat the card I am my missing something but this method didn't work for me. I was happy to see-it working but when I was looking at the storage was nothing.

I will try different approaches to see what will work.

Bellow is the screen of my card after partitioning and I don't think I do anything wrong but the problem seems to be when I put the card back in the phone.
[HD2 Android SD Development] gitanojr:
Glad i could help :)
[HD2 Android SD Development] georo:
Hooray finally got-it to work following this http://xdaforums.com/showpost.php?p=10725793&postcount=119

Thanks to everyone here helping me :D Working smooth so far I didn't try all the features but I unlocked and I install few apps with any glitches. Also Android work like a charm to.
[HD2 Android SD Development] hyellow:
Yeah, i think it sometimes screw up when you put the sd card back in. try it a few times, eventually it'll work.
[HD2 Android SD Development] darren211:
can i used windows 7 on NAND 4GB, and android on 8GB memory card ...i mean can i used 2 memory card to run different operation system??..
[HD2 Android SD Development] darrengladysz:
Yes you can.

U can choose to run Android SD with WP7 on NAND,Just follow the thread

Tutorial How to partition sd card to run wp7 and android from same sd card

Or just choose USB Flasher in MAGLDR menu,Everything is very easy if U search for the answer in the forum~~
[HD2 Android SD Development] timmy1980:
Hi there,

Great guide... although!!

I seem to be stumbling quite early on! At the following point:

"It asks you to confirm it two times, so at the second confirmation, pull out the sd card quickly and confirm the reset immediately."

I do this and when I put the SD in my card reader I only 200mb of unallocated space, same as I do if I set up WP7 shut down and pull the SD.

Sorry if i'm being a fool here!!

Thanks for any help and for putting this together in the first place.
[HD2 Android SD Development] hyellow:
In about screen, reset your device and leave sd inside. When rebooted into magldr, pull sd card out and make partition for wp7, but leave 200mb fat partition as is. When still in magldr, insert sd card and continue initial setup. Verify your sd size in about screen. If good, power down device and partition the rest. Try it.

Sent from my HD7 T9292 using Board Express
[HD2 Android SD Development] timmy1980:
Thanks, I tried that but all i see is 200mb of unallocated space still... See attached.

The only option I have is to create a new partition in the 200mb of unallocted
[HD2 Android SD Development] iwanrakic:
Your method definitely works :)

This is how my partitions look like:
[HD2 Android SD Development] hyellow:
I am glad that it works for you and you have verified that this method works for real.
[HD2 Android SD Development] miren007:
I have tried the method proposed by HYELLOW (using single SD card) multiple times.

But when I start wp7 after creating the partitions, wp7 re-creates the partitions to the original size, i.e, 200 mb fat 16 and rest unformatted.

have followed the entire process as is. I dont know where am goin wrong :confused:

Please help :(
[HD2 Android SD Development] hyellow:
have you tried my revised method? one post above? it should work.

again:

with the sd card inside, go to about screen en reset the device. (make sure you set the magldr bootscreen is always shown at startup)

when in magldr screen, remove the sd card and insert in your pc and delete the unformatted partition, click apply and create a new unformatted partition. Set it as primary in the resize screen and move the partition to the end of the sd card leaving a little bit of Mb's left at the end and click apply.

Put the sdcard back your phone and boot wp7 and just let it go through the setup.

Go to the about screen and check the storage size. Is it the same as you have created, then power down the device and put the sd card back into your pc, where you can now set up the partition for use with android.
[HD2 Android SD Development] timmy1980:
I have followed this and i still get what is shown in the screen shot I attached earlier... I think it must be something to do with my SD (which works fine in WP7) or the card reader in my laptop.

Thanks for the guides and for the help peeps! I'll try with another reader I think and see what happens.
[HD2 Android SD Development] hyellow:
you could try the panasonic sd formatter, also somewhere to dl in this thread. I have not used it before, but some people have revived their sd card with it.
[HD2 Android SD Development] timmy1980:
I'll give it a go, thanks. I have managed to get it back to 8gb unallocated a few times but every time I then start again and get to the point where I reset my phone and then take the card out whilst in magldr it states that it is 200mb of unallocated space and no other partitions or space
[HD2 Android SD Development] gitanojr:
ok i have a 8gb sd card, installed wp7 on it, went to "settings", "about" then "reset device" leaved sd inside, whenn booted in magldr, pull sd and inserted on sddcard adapter, opened EASEUS partition manager, in there i could see the "200 mb" fat 16 and the "unformated" about 7.50gb which in this case is wp7 partition.

Deleted that "wp7" partition, then created another one "unformated" with a size of 2.01 gb and was left with "5.26 gb" of unallocated, removed sd card put it back to the phone, while being still on magldr screen boot up wp7.

Then it got stuck at the "go go go" screen, removed battery, then restart it and boot wp7 again but this time it did boot, after set up went "settings", "about" and:

Total storage: 5.25 gb

Available storage: 4.98 gb

Turn off phone and put sdcard onto the sdcard adapter, open the EASEUS Partition Manager and got this:

Fat16= 200 MB

Unallocated= 2.01 GB

Unformatted= 5.26 GB

So it seem that wp7 likes bigger partitions cause converted my 2.01 GB unformatted partition to unallocated, and decide to use and covert my 5.26 GB unallocated partition to Unformatted and install it self there :/

This happened cause i had to remove the battery after it got frozen on the "go go go" screen?? or because i left the 5.26 GB unallocated partition?

Anyone else has the same problem??
[HD2 Android SD Development] hyellow:
ok, just for trying:

when you have the 8gb of unallocated memory, try to format it first with windows format tool. format it to fat32 and then restart the procedure. don't know if it helps, but you could try it.
[HD2 Android SD Development] timmy1980:
Will do, thanks for the help!
[HD2 Android SD Development] timmy1980:
Still the same outcome. I reckon it must be card reader related as I tried putting the card in my Desire and when I plugged into my laptop it saw the 200mb fat 16 partition... nothing else though, not even any unallocated space!
[HD2 Android SD Development] hyellow:
do you have another sd card to try?
[HD2 Android SD Development] gitanojr:
Tried all your methods but it doesnt work for me :/

No matter what i do, after making the changes wp7 setup always partition my sdcard back to 200fat and the rest "7.26 GB" :(
[HD2 Android SD Development] timmy1980:
Yeah i've got a 2gb class 2 and it does the same thing so it doesn't seem like it can be the card
[HD2 Android SD Development] hyellow:
try to set the WP7 partition to logical, rather than primary.
[HD2 Android SD Development] zarathustrax:
Your method finally worked for me when I set the wp7 to logical... (the only other thing I did different was leave the phone on in magldr menu while doing the partitioning instead of turning it off to save battery, so it's possible that is what made the difference, too.) But now I can't change the partition back to primary... if the wp7 partition is logical, the android build can't mount the sd card. Anyone know how I can change the logical wp7 partition to primary? The option in easeus to change it is grayed out... I assume it's because it's an unformatted partition. Does easeus give you an option to change it if you copy the wp7 partition to another sd card? Any other way to change from logical to primary?
[HD2 Android SD Development] hyellow:
no, you have to set that from the beginning. I am also struggling with the android builds.
[HD2 Android SD Development] gitanojr:
For you to be able to change it to primary is to get another card.

U can use your sd card adapter for one sd card and u can use another phone to mount the other sd card, u must not use mgldr to mount a card, cause I believe cotulla said something is wrong with, and i test it, so do not use mgldr to mount sd card.

after u have both sd card mounted open easeus and just copy the wp7 partion to the other sdcard and it will give you the option to change it to "primary", try it and let us know...
[HD2 Android SD Development] zarathustrax:
That's the problem... only way I could get your method to work was to set it to logical, but if it's not set as primary, then there are problems with android and sd card can't be mounted. Have you managed to get your wp7 partition set as primary with your method?
[HD2 Android SD Development] zarathustrax:
Ok, hopefully that'll work. I have my data from my other 32gb being backed up to my computer right now, so once thats done, I'll try transferring the wp7 partition and change it to primary then. I've got a few microsd card readers, so I'm fine in that regard. I'm just trying to give wp7 20gb and android 9gb... that's why I'm using hyellow's method. I'll let you guys know if it works and solve the problem with mounting sd in android. Thanks.
[HD2 Android SD Development] jzack:
any tutorial video?

can i make a request here? if someone would create a tutorial video on this.. we would be highly appreciate on your tuto ^.^
[HD2 Android SD Development] hyellow:
ok, another program is involved for this. Another partitioning tool, that can convert the logical partition that you have created into a primary one. almst the same UI. Only strange that you can not resize the fat partition.

ok, my android build is connected as usb diskdrive to my pc now. wp7 still boots fine. However, i am still facing issues that i did not have when i would run this build on a standalone SD. For example, I can not get into the settings menu, as it says that it has been removed. Really, how can the settings menu be removed? I am using Phiremods 2.1, one of the best, imo. I don't have a long history in Android, as my ex-HD2 was smashed in the period that Android came out. I just recently bought another HD2.

So, maybe someone could download that build, copy it to a dual-partitioned sd card, boot it and let me know what's the deal?

Here is the link to the build:

Can someone with a greater Android Knowledge test this for me? You would have to edit the rootfs.img, but I guess you'd already know.

https://sites.google.com/site/phiremod/roms
[HD2 Android SD Development] hyellow:
what part of the tutorial do you not understand? we can help you with certain parts.
[HD2 Android SD Development] zarathustrax:
I already have a copy of phiremod edited for magldr booting, so i'll check that build out for you once I get my partitioning all worked out. So you used that program you posted to successfully change from logical to primary? I'll give it a try... thanks.
[HD2 Android SD Development] hyellow:
yes, after I created the logical partition with the other program first, I checked if WP7 would recognize it. After that was done, I powered down and converted that partition to primary (took a minute or two) and the inserted back to check again in WP7. After that I resized the fat partition in the first program, because 'partition wizard' would not allow me to do so. Then checked again in WP7 and all was still good.
[HD2 Android SD Development] zarathustrax:
OK, great to know that works for sure. I'm currently copying my working wp7 partition to my other 32gb microsd card and changing it to primary that way... doing it this way, it takes a lot longer, but I'm seeing if I can put the partition all the way at the end to recover the 20mb or so unallocated space that I left at the end of the card and then I can repartition the fat32 section to use the rest of the unallocated space on the card... this way I'll be using all the space available and none is wasted... (i know, it's only 20mb... but I had already started doing this before you posted that other app, so I figure I'll let it finish to see if it works.) If this way doesn't work, then I'll use the app to do it.

Once I get everything settled, I'll test out phiremod and see if I have problems.
[HD2 Android SD Development] hyellow:
ok, thanks in advance for testing. I am also not wasting any space anymore, don't know what the purpose of it was, but it wasn't nescecary. Copying the partition back takes a long time ain't it? I have it done once before and found out WP7 reformatted it again. lol. I hope it works for you that way.
[HD2 Android SD Development] zarathustrax:
Oh, you don't have to leave that space at the end after initially changing the wp7 partition size? If that's the case, it would probably just be quicker for me to redo the entire process and just use that second partitioning app you posted.
[HD2 Android SD Development] hyellow:
no, not anymore. But i do verify the sd card a lot after each change i made. just to be safe though. make sure to create a logical partition first, let wp7 see that it is cool and then convert using the other program. Right click and selct modify.
[HD2 Android SD Development] zarathustrax:
Thanks a lot... I got everything working great now. I just started over and used that 2nd app to change the partition to primary, and my jdms build can now mount the sd with no problems. I partitioned my sandisk 32gb card to give 21gb to wp7 and almost 8gb to android, and both OS's are working great so far.

I'm gonna put my copy of phiremod on my sd and check that out for you... i'll let you know how it works for me.
[HD2 Android SD Development] georo:
Hey guys for those who has only one card I recommend this program is free http://www.paragon-software.com/home/db-express/download.html

I used to make backups and then restore the image wherever I want.

Make a backup of the WP7 partition in your PC and then reformat your card as you wish and leave the space unallocated for the WP7. Then restore with this program the partition you saved on your unallocated space. Is fast and simple.

Let as know if was helpful after you try-it.
[HD2 Android SD Development] zarathustrax:
hyellow... I tried booting the copy of phiremod final that I had (edited the init.rc file inside the rootfs.img), but can not even get it to boot... it's the first build that I've had trouble getting to boot. Then I noticed you said you were using phiremod 2.1, so I'm downloading that now and will test it tonight. Did you do anything else to it to get it to boot beside add "nand_init" to the line in the init.rc file inside the rootfs.img?
[HD2 Android SD Development] bteljuice:
I am using the SINGLE SD CARD PROCEDURE.

Can anyone help me with this step please.

3. the 200mb fat16 partition is for your android build. Because we moved the WP7 partition to the end of the sd card, we are now able to resize the Android partition.

Notice you still had some unallocated space left when you determined the size for your WP7 partition. Except for that tiny little bit of unused Mb's at the end of the sd, you are allowed (supposed) to use all of the remaining Mb's/Gb's for your Android partition. First resize, and click apply. If partition is greater then 4Gb, it'll automaticaly become fat32. After that, you could format it again with your desired cluster size. Ok, check everything and proceed.

This is what I have so far.

Can Please anyone assist me with this step.

EDIT: I think I figured it out. Will report back

EDIT 2: I boot to WP7 with Android on my SD card, didn't erase it. But in the WP7 about, it shows 10GB when it should show 5gb. And in My android, it shows 10Gb, which is currect. So why doesnt WP7 show 5gb in the about :(
[HD2 Android SD Development] zarathustrax:
From looking at your picture, you don't even have a wp7 partition on there. It probably has 10mb left, not gb, cause you have no "unpartitioned" partition. And you have a 200mb primary still there that should have been expanded into your fat32 partition for android, and then you have 10gb of space not even used, then another 5gb fat32 partition that probably isn't being read by anything. You should carefully read through the directions and redo it... use the more recent directions that hyellow gave in the last couple pages... actually if you read through the last couple pages, you should get a good idea on how it's done. It worked great for me... there's another app the hyellow post a page or 2 ago that you're gonna need to change you wp7 partition from logical to primary. If you have trouble after reading last couple pages, let me know... I'll be up for a couple more hours.

Start at post 235... main directions are there, except instead of setting the wp7 partition as primary, you have to set it as logical at first. Read from that post up until current post, as a few more details were added like the fact that you don't need any extra mb of unpartitioned space at the end. You should be able to use all of memory card and end up with only 2 partitions.
[HD2 Android SD Development] bteljuice:
Thank you so much for your help.

Ill read back a few pages . Only read the 1st post (still confused :( )

I redid the steps around 5 times not really knowing much of what's happening
[HD2 Android SD Development] zarathustrax:
I just added some to my post above... start at post 235 and read up until current. Read the other stuff I added to post above yours, too.

Once you get the hang of it, it actually gets pretty easy. I've redone it a couple times now... it doesn't take long, either.
[HD2 Android SD Development] bteljuice:
Thank you kind sir. Will read further more.

This is where I am at so far.
[HD2 Android SD Development] cib3rt00th:
Hey guys fter 5 hrs of trying, finally, i figured out a way to partition wp7 with out a smaller card, since i don have one (i got two 16 gb).

just go to about and then reset the phone and wait till magldr shows up, pull out the card and insert it into your pc. use the partition software provided on the first page, and delect the unformatted partition and apply. The tricky part that i figured out: when you try to create the unformatted partition on the unallocated space remember it has to be in logical and then when it comes to assign amounts of space for the unlocatted space before and the partition and the unlocatted space after, you have to put a large amount of spacce on the unlocatted space after, because after times of trying i realized the wp7 ll choose the larger one to be it's partition...so if you have 15 gb like me you could put (4.5 gb before 5.0 gb partition and 5.5 gb AFTER !) so after that you ll have the wp7 partition at the end and a unlocated space in middle for you to merge it with the fat 16 200mb partition. got it? hope you guys understand my english and good luck ^^
[HD2 Android SD Development] zarathustrax:
I sent you pm. From your picture, it looks like you keep making the wp7 partition into fat32... it needs to be left unformatted. Also need to set as logical at first. It shouldn't be able to be named, i don't think either. Just follow the directions I sent in pm exactly.
[HD2 Android SD Development] hyellow:
no, i just added the nand_init line to it. It boots, but seems to have difficulty doing some startup actions. In a standalone SD it would take me through the inital setup, like select language, wifi network, accounts etc. Widgets are also not loaded etc, shortcuts to missing programs, like the settings menu etc.
[HD2 Android SD Development] WaveMaster1406:
That's a good job!

I thought of a method in this kind. but yours is so clear and accessible to all!

Thanx bro'! And works very well for me!
