[Remix OS for PC] nenitosoyyo:
Now just posting this here because with a mix of the instructions here and another post I was able to install dual boot Linux Mint(ubuntu) & Remix OS on my HP Envy DV6-7250CA. I don't want to make separate post because I don't like going into details, and just want to leave it somewhere if someone needs it XD.

1 - First thing I did was download a copy of Remix OS at http://www.jide.com/remixos

2 - I used my usb drive that has Easy2Boot, which saves so much time with future projects to swap linux or whatever bootable .iso's you need, check out http://www.easy2boot.com/ on how to set that up and put Remix OS in the linux folder.

3 - Downloaded a stable copy of GParted iso to partition the hard drive for Remix OS in Ext4 format. Can grab that here http://gparted.org/download.php and also pop that in the linux folder of the E2B flash drive that you made that you put Remix OS on.

4 - Load up the laptop and hit F9 and boot in to the E2B Drive, once that loads go into iso's and linux and find gparted and load it up, its pretty straigh forward.

5 - Partition the Hard drive you want Remix OS on and can name it "Remix OS" hit apply to start the partition and once done, check which SDA it is example(SDA2, SDA3) exit GParted.

Now I am going by with that you have an knowledge installing linux which is why I am not going into detail, oh and that you have linux installed too. Also you can make your separate bootables for the Gparted and RemixOS I just prefer the E2B.

6 - Now the laptop should reboot again when you exit GParted and hit F9 again and load up E2B Drive again, and this time select Remix OS iso.

7 - Choose Resident Mode and hit "TAB" or "E" to edit and delete DATA= USB_DATA_PARTIOTION=1 and replace it with INSTALL=1

8 - Hit enter and select your partition you made for Remix OS, do not format it since it was done with GParted already

9 - Skip GRUB2, and skip EFI GRUB (if it comes up, didn't for me)

10 - Yes to Write/Read

11 - Reboot, and now you should be heading back to Linux

12 - Now lets install grub-customizer

sudo apt-add-repository ppa:danielrichter2007/grub-customizer

sudo apt-get update

sudo apt-get install grub-customizer

13 - now go open up grub-customiizer, for me its under Menu>Administration>Grub Customizer. Once its open hit Ctrl+N and name it Remix OS and for Type choose other, under Boot sequence put this, remember X is for the drive it is on, usuallly 0 if its just one drive in your system, and Y is the partition, so if the partion was SDA2, then it would be 2 example(hd0,2). You can also tweak the screen size(UVESA_MODE part) I just left it at 1080p.

insmod gzio
insmod part_msdos
insmod ext2
set root='(hdX,Y)'
linux /RemixOS/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive SRC=/RemixOS UVESA_MODE=1920x1080 verbose logo.showlogo=1
initrd /RemixOS/initrd.img

Below is what I put for mine, I only have one hard drive in and the partition for remix was SDA3 which is why I have 3 there

insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,3)'
linux /RemixOS/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive SRC=/RemixOS UVESA_MODE=1366x768 verbose logo.showlogo=1
initrd /RemixOS/initrd.img

14 - Once that is finished hit ok and drag Remix OS to second place under Linux

15 - Under General settings tab have predefined as First Entry, and show menu/look for other operating systems/boot default entry 5 seconds all checked

16 - Now hit save button reboot and you should be able to see the grub with Remix Os in the list, boot Remix OS and have fun ^_^
