Installation[edit | edit source]

Installation guide on QEMU:

1. Download this pack on QEMU 6.2.0

2. Download a patched Linaro UEFI 15.12 32-bit and copy this file to the QEMU installation folder.

3. Create a VHD by using the diskpart utility. For this, run the following commands. (Note that these files will be created in a directory on your C drive called "RT", and they will be mounted under the drive letters P and W).

create vdisk file="C:\RT\hdd.vhd" maximum=65536 type=expandable
select vdisk file="C:\RT\hdd.vhd"
attach vdisk
convert gpt
create partition efi size=100
format quick fs=fat32
assign letter=p
create partition primary
format quick
assign letter=w

4. Apply the install.wim to VHD, and then create boot files:

dism /apply-image /imagefile:<WIM file path> /index:1 /applydir:W:\
bcdboot W:\Windows /s P: /f UEFI

After that, eject P or W. Once ejected, P remains and disappears after a reboot.

5. Run QEMU by going to your QEMU installation folder, saving the following text to a batch file, and then running it to start the emulator:

qemu-system-arm ^
-M virt,highmem=false ^
-cpu cortex-a15 ^
--accel tcg,thread=multi ^
-m 2G ^
-bios QEMU_EFI_1512_driver1998.fd ^
-device VGA ^
-device usb-kbd ^
-device usb-tablet ^
-drive id=mydrive,if=none,file=C:\RT\hdd.vhd -device sd-card,drive=mydrive ^
-rtc base=2012-04-24,clock=vm

6. If you want to change the screen resolution, press F2 to enter EFI settings, enter Device Manager and then OVMF Platform Configuration. Change the resolution to the desired one then commit the changes and exit. Choose Machine in the QEMU menu and then reset the emulator.

Important note: The startup process is highly unstable and recovery errors are possible. You must bypass them, to do this, press the Enter key. BSOD errors are also possible. To bypass them, reset the emulator every time you get a BSOD error. After several attempts, you should successfully boot into the system.

Changes[edit | edit source]

Hardware compatibility[edit | edit source]

This is the first build of Windows 8 that drops support for processors without NX, as running on these processors will result in a black screen with error code 0x5D.

This is the first build to feature the new "Windows 8/RT" branding seen in the RTM.

Setup[edit | edit source]

  • Besides the background color, Windows Setup now resembles that of the RTM.
