Can you provide a bit more clarity to your problem.

Does this happen with both the 8gb and 16gb cards? Also what build are you using when your phone gets hot and restarts or freezes?

I find it strange that it is fine when you are using either Android or WP7 without dual boot as you are using only one build at a time when dual booting. You are only gaining access to different partitions on your card, pretty much the same as you would if you have an EXT2/3/4 partition for data saving in Android. Do you still have the same problem if you partition you SD card for a EXT2/3/4 for data saving?

From what you have said the only possible reason is somehow your phone might have a problem dealing with partitions because in theory dual booting runs either one or another and shouldnt be different if you were using only Android or WP7.

Using Minitool's Partition Manager, you might also want to try formatting the Fat32 partition by right clicking on Fat32 partition, click on Format and choosing the cluster size to 32. Save these changes and try again.

The solution could be setting up Android to work properly. In DL Desire's build, there are quite a few options as to how you save your data. You have the save to Data.Img file which must be placed inside the directory for the build, and without going through every type there is also save to EXT2/3/4. You must alter the values in the Config.txt file for the build to know where to save data. Double check you have setup the Config.txt file correctly as you could be telling the build to save to EXT2/3/4 when there is not one. I dont know but it could affect the WP7 partition so it corrupts it and causes the above mentioned problems. Always read the chefs installation notes. Try installing MarkinXHD Extra Clean Magldr Build instead of DL Desire just to make sure.

Can anyone else throw any solutions to this problem?

I completely agree with the community sharing knowledge and that was one of the main reasons for me posting this tutorial. I am a strong believer in if you give a man a fish, then you have provided one dinner but if you teach that man to fish, then he has a lifetime worth of meals.

It would be very generous for you to share the builds you have converted to boot into Magldr as it would give people more options to what build they can choose to dual boot WP7 with. As a matter of fact, being certified in Microsoft, I was looking into doing this myself and was the next mission for me. I have limited Linux use but I am starting to sink my teeth into it and become fluent.

Hey which would be the best way to do this activate my phone when i get it then flash, or flash and activate the phone service after i install the Os's.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
What do you mean by activate? Do you mean get your activation code? If so, get it anytime... you will need the activation code to use live services in wp7 anytime you flash a new wp7 rom. If you mean activate your cell phone service, that can be done at any time, also.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
Thank you for the YouTube link to the same process as described in this tutorial.

I have watched the video and it does not mention that you have to change the Unfomatted partition from Logical to Primary. This is essential if you want to use the camera and to gain access to other files such as music from you SD card. Also in the video it is being demonstrated in Easeus Partition Manager. This is a good program but with it you cant change the Unformatted partition from Logical to Primary. This is the main reason I chose to use Minitool Partition Wizard. With this program everything can be done.

If you look in the description there is a link to the minitool and a description why you have to use the tool. The original thread is here http://xdaforums.com/showthread.php?t=913815
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
Thank you pointing this out. I easily overlooked this and should imagine a great number of people would too. Why use two partition managers when you can just use one. As mentioned, this was the reason why I chose Minitools Partition Wizard in this tutorial.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] jab12:
ok thanks i meant cell service, so i guess it doesn't matter just making sure.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] justin89:
it would be so cool to get this working
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] APJG:
Oh man, thanks so much for the tutorial! Everything else I've been checking out has been a bit confusing, but this was super straight forward!

FYI, I used "Mass Storage" through Magldr rather than a card reader and it worked fine :D
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
You're welcome. It was because I were a bit confused when I was looking into Dual Booting what prompted me to write this tutorial. You must be using the latest Magldr then as there were problems using Mass Storage in version 1.12.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] APJG:
Yep, I had updated to 1.13 right before I started your tutorial! Good thing too, I would have been really bummed if it didn't work haha
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I have updated my tutorial in view of you reminding me about Mass Storage issues with Magldr 1.12 so thanks for the heads up. I'm glad the tutorial went well for you.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
There are still issues with Mass Storage Mode in Magldr 1.13 as stated by cotulla. It will not always work, just like with earlier versions. Cotulla tried fixing it, but it still can cause issues, and he stated he will try to fix it for version 1.14. It may work fine sometimes, just like earlier versions, but I would definitely let people know it may cause corruption issues.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I was under the impression Mass Storage had been fixed. I have updated the tutorial in light of this so thanks for pointing it out.

Any news on the SD builds which you converted to run in Magldr. I am sure there will be lots of people using this tutorial who would love to have more choice to what there already is.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
I'm working on getting them organized and all in my dropbox for easy download... In the next day or 2, I'll edit the second post in this thread and post them all there so that they will be right after your tutorial. If anyone need a specific build before then, anyone is welcome to pm me and I'll be glad to send them a copy.

But, yeah, as far as magldr mass storage... cotulla thought he fixed it and posted that it was fixed when he uploaded 1.13, but he has since admitted it's still broken. It'll work a lot of the time, but not always... so if you have a card reader, it's best to use that...but if you don't have anything else, go ahead and use magldr mass storage, but if something doesn't work, just keep in mind that it's possible the files transferred with magldr could be corrupted. Hopefully by next version, it will be fully functional.

Hello thanks for the clear tutorial.

I followed the intructions step by step twice now. All goes well until I boot Andriod for the first time. Andriod boots up.. all the way to the welcome screen. And at this point andriod hangs.. with a message at the top saying: "The storage card is almost full" I used the Desire_Z rom specified in the tutorial.

I also noticed in WP7 that my storage space is 15 mb? Guess im doing something wrong?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
If WP7 says you only have 15mb, then it is not using the card. Either you had the card out while wp7 was on at some point, or wp7 is having problems with the card, or something messed up. You should start from the beginning. If WP7 still keeps losing the card, it's possible that the card isn't compatible. WP7 is very picky about what cards it'll accept.

As far as your problem with android... how big did you make your android partition. I'm not sure if that build creates a data.img at first boot, but you have to make sure there is room for it. You can try a different build, too... I tried the DesireZ build out a couple weeks ago, but it didn't perform very well for me. I much prefer aosp or cm builds myself. If you want to use a specific build that doesn't have magldr compatible files, let me know. I have pretty much every sd build I've tried from December til now working good. I'm going to be posting links for all my edited builds in post 2 of this thread soon, but if you want one right away, just pm me and I'll send you a download link.

Does anyone know the original instructions on on how to dual boot WP7 and Android?

I wanted to have a 4GB WP7 build and a 10GB Android build and the use of 2 SD cards from the earlier instructions were the only way I could do it.

I tried to tweak these instructions, but I still can't create a smaller partition that WP7 will recognize.

Update:

Nevermind, I found the instructions in the Android forum...

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
OK, glad you found it. The link you provided was where I first tried to dual boot and the 2 SD card version wasted me two days trying as I had to wait almost 2 hours just to copy a partition from one card to the other and for me, it wasnt very clear. In light of this and the second part being the better way to do it out the two I decided to write this for WP7 users who might also want Android as well. Many people also dont have two SD cards to use thus making this tutorial the most appropriate.

I could provide a tutorial for people wanting to upgrade to a larger memory card but still keep their WP7 data if people want it.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] georo:
I use the two partition programs because a lot of guys when they open the Minitool they see the partitions as "Other" not FAT16 or FAT 32. and they are confused and as you see in the comments they complain about that. This is the reason I use both of them.;)
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I am glad that doing it that way worked for you, I really am but please dont say people are moaning about my tutorial when I have had nothing but good comments and thanks from people who has tried it ;);):D

I have tried to make it as easy to follow as possible, it is only you complaining about me using one partition manager instead of 2. If you can write a better one then be my guest.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] nutmegy:
the partition sizing bit caught me out initially.. i had one of them a fraction smaller and it kept on ordering it incorrectly.. watched the videos (with the sound off stupidly)lol
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
People are having problems sizing the partitions to suite them.

This is a known problem where the WP7 partition has to be larger that the Fat32 partition and a solution is trying to be found.

Please don't get me wrong I didn't say people in here moaning about your tutorial

I was saying in my tutorial people complaining about Minitool and I didn't try to promote anything here I just want to help as much as you and is nothing personal or something close to that I am here to learn and help as much I can.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
If you make the unformatted partition to the right smaller than the unallocated space to the left, wp7 takes the bigger one as it's partition, so he would end up with wp7 taking the 11gb partition instead of the 4gb partition. This was a problem that kept coming up in the other thread. That's why in that thread the instructions say that the wp7 partition must be bigger. I think some people figured out a way of making the wp7 partition smaller without needing 2 cards... I'll see if I can find it. I plan on repartitioning my card soon, also, so I might do some experimenting to find a good way of making a smaller wp7 partition.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I see what you mean now. I have just tried a various of different ways to get a 3gb wp7 partition on a 8gb memory card. On one occasion I thought maybe adding another Primary NTFS partition might work but WP7 took over the unformatted partition, unalloated partition and the NTFS partition and made it its own.

This is something which needs to be looked into more and hopefully a solution can be found. I will try various ways into the night and see what I can accomplish.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] boyd4y:
Nice guide for me, but still a little confused about the partition in the sd card??

In step 6, create unformatted partition at the right, i try, but after apply, in setp 7, WP7 can't boot up.. hang at go go go!!.

i also go through, seems currently, we need make sure wp7 partition a little bigger..

so, i do that, still doesn't work for me, wp7 can't bootup..

but if i create the unformatted partition at the left, that mean the blank grey is on the right, wp7 can be boot up, but on step 9, after delete 200MB partition, there are 3 partitions left in my card (i guess it's caused by these two partition is not continuous, if i create unformatted at the right, these two partition will be merged as one), as following: (16GB card)

1. 200MB unallocated (deleted)

2. 7.37 GB Other format, primary (should be WP7 one)

3. 7.33 GB unallocated， (left in step 6)

After that, i should use the 3 partition, because it's larger, and android sd build may try to init a user data (1G).. but problem is windows only recognize the first partition... 200MB is not enough for my android sd build...

What's wrong here?

also, want to know, how many partitions left finally? can someone help list?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] sydako:
Hello thanks for the tutorial. It´s just that im searching for.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
When you create the unformatted partition to the left, do you make it as logical first? It needs to be logical first, then later is changed to primary after wp7 accepts the partition. I can't think of any other reason it wouldn't work except maybe memory card problem, but if it works with partition to right, it should be a problem. How many times did you try making it on the left? Because I've had it freeze at go go go when doing sometimes, but it would work after trying again. Also, at times when making partitions, it would sit at go go go for several minutes and act like it's frozen, but it would start loading after a few minutes.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Angelusz:
Thanks for this guide. I'm currently trying to set it up, but got stuck.

I've got WP7 running (without internet for some unknown reason, might be the ROM I'm using), and trying to install android. This is where I get stuck.

Whenever I connect my SDcard to my pc with a USB adapter, it detects the device, but windows doesn't recognize any storage device (win7). When using the partition application, the device shows up just fine, I've got two partitions nearly equal in size, one fat32, the other unformatted (other).

Since that didn't work I figured I'd try it through magldr mass stg mode, which didn't work for me - the magldr bug.

Now I'm stuck... halp! :)

EDIT:

Just found out that the few files I did manage to copy through magldr are placed on the fat32 partition, which I think is used by WP7.. fail!
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Android uses the Fat32 partition, and it should be the first partition. WP7 uses the unformatted or unknown partition, which should be the 2nd partition. It's best to use SD reader to copy files as magldr can corrupt files when using mass storage mode.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Angelusz:
Thanks for your reply. My bad there then. Didn't help the situation though; Ì still cannot access my SD card since it has two partitions, while I could before.

Any ideas?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Are they both primary partitions? And the Fat32 partition is located first, on the left? If so, I don't understand why you wouldn't be able to read it on your computer. You will only be able to see and access the first fat32 partition with your computer... your second partition, the wp7 unformatted partition can not be seen or accessed except with a partition manager... you can't copy or read files from your wp7 partition except by wp7.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
I'm going to experiment and try to figure something out when I repartition my card tonight or tomorrow.

Also, I started editing the 2nd post to include download links for my edited magldr compatible android builds. I'll be adding more as I get organized and clear some more space in my dropbox to upload to.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Angelusz:
Yep, it's exactly as you say. I find it very weird myself. Also, since I can actually access it through magldr it should work. I'll try it on another PC as well after this post.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Maybe it's your card reader, then. It's gotta be if you can access it through magldr.

I've been able to access it through another PC. I'm not sure what the cause was, but I can set up an android install now. Working on that next.. first attempt failed - I must've missed a step in transferring android to the SD!

EDIT:

Ugh, frustration is rising.. I'm trying to install the Desire_DL build 3.4. I've made a "Desire_DL" folder on the SD card and copied all files there. Magldr reports that zimage kernel is missing.. how do I build it? I did set the right folder in the boot options btw. Any advice?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
Maybe you need to check your card for bad parts on it. It is easy done, simply put your card in the card reader (Not using Mass Storage in Magldr), right click on your card and choose properties, click on the Tools tab and hit the Check Now buttor for Error-Checking. Check both boxes and click Start. If you have a bad sector on your card then is it will only affect whatever you are doing once the sector is being used. Worth a try and it will keep your card healthy.

For the Desire DL build you have to configure the config.txt file in the main directory. You are not using an ext2/3/4 partition and you have to use a data.img and place it in the main directory. Now you need to tell the build to use the data.img for your system data etc. Open config.txt and set it as follows.

boot_mode=2

ppp_mode=0

data_img=1

gps_zone=us, gb, fr etc depending where you live

Make sure the name of the foler is Desire_DL and you should be good to go.

Thanks, but when I do that, I get the exact same error. It's searching in \Desire_DL\zimage - that folder doesn't exist... what am I doing wrong..?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
You have magldr set to boot from the Desire_DL folder, right? Maybe try a different build. I put download links to some of the builds I've edited to work with magldr in post #2 of this thread. I also have many other builds working, so if there's a specific build you want, let me know.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
In that build both Zimage and initrd.gz are both in the main Desire_DL directory. Have you set the boot settings properly for that build. Double check they are both in that folder.

In Magldr select Services, then BootSettings, then AD SD Dir. Now Select DESIRE~1 and it will take you back to the main Magldr menu. Select Boot AD SD and see if it works.

If not then tell me what the message says and I will try and help if I can.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Angelusz:
Yes, I did that. Looks like the files I'm trying to use simply won't work with magldr. Can you try and get it to work with Desire_DL? I'd love to use that android, but my android knowledge is just too limited to fix this up.

Same as above, I'm using the wrong files, but tried the right settings.

Interesting issue with mine. Win 7 is running fine. However, when I try and reset Win7, restart into Magldr 1.3, pull the card out, fire it up in Windows, and start Minitool, it ONLY sees the 200mb partition. I have tried 3 cards now with the same result. 4GB, 8GB C4, and 16GB. All the same results. Also tried 2 seperate card readers. What am I missing here?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
If you went though the steps in the tutorial and reset WP7 and it had fully setup when you reset, then you should see the unformatted partition as well as the 200mb fat16 partition in Minitool Partition Manager. You also say you have tried 3 cards and 2 card readers.

The only solution may be a driver issue on your pc. Try this. Open Control Panel and then click on Device Manager, click on the white arrow next to Disk Drives to expand it. Now plug in your card reader and Device Manager will reset and the card reader will now be shown in Disk Drives. Right click on your card reader you have just inserted and choose Update driver software. Now choose 'Search automatically for updated driver software'. The PC will now search preconfigured drivers on the PC and the Internet for updated drivers. It is always good to try this as sometimes drivers can get messed up. Once it is done and if it says new drivers have been updated then try it again with Minitool Partition manager. If however it comes back as saying the best drivers are already installed then I am just as puzzled as what you are.

Have you tried completly uninstalling Minitool Partition Manager and reinstalling it in case it did not setup right in the first place.

Help!!! :)

Something weird is going on here on mine.

I follow the partitioning part as instructed but when I get to the part where you resize the FAT16 partition I am unable too because the unallocated space is positioned to the right with the unformatted in the center ?? I have tried various ways but each time the unformatted partition ends up in the center so I cannot resize the FAT16 partition.

What is going wrong?

I am trying to set a WP7 partition as large as posible leaving 6gb for the Android Partition.

Why does it keep putting the unallocated partition to the right?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Is your wp7 partition bigger than the android partition? Wp7 will take the bigger sized space, so if unallocated is made bigger than the unformatted partition to the right, wp7 will take the bigger, middle partition. I'm going to be trying to work on workarounds soon, but for now, I'm not sure how to make android partition bigger than wp7 partition.
