a chance to dualboot windows rt - Windows RT Development and Hacking

For me this is a way to dualboot windows rt tablet
In the sistem registry its an key with a reference to the uefi? This f****** uefi is managed in a place? Or no?
I think in the file sistem its a uefi.ini file with the info and settings,the only mode to see it is monitoring with another computer the surface when go in recovery mode and see in what directory he go,unfortunately i can't but someone can do this?
thanks
P.S ptsss check my another question tread http://forum.xda-developers.com/win...t/help-installing-scummvm-windows-rt-t3264783 thanks

UEFI blocks installation of other OSes. You can however use bcdedit to install other Windows on ARM versions and Windows 10 IoT Core

You can just use Windows 10 IoT Core because of Secure Boot

How i can install this ?, and what features have this OS?

It's the version of Windows 10 for the Raspberry Pi 2. You follow the same instructions as installing on a RPi, except you flash into an USB stick instead of a microSD card

[Q] Windows 8 on Transformer Tabets, Would This Work?

This is more of a question for all Asus Transformer tablets, would this work?
Step 1: Root device
Step 2: Install Unbuntu (some apps let you)
Step 3: Install windows 8 for linux devices.
I dont know if this is againts form rules since this is a question, but could someone try it, I would but my test tablet is getting fixed..
I just thought of this, I hope it will work!
I like the idea, but i am seeing a couple of problems: running windows in linux on an android is probably going to cause a lot of lag. Are you sure you can install windows in linux? do you mean a virtual pc?

There is no "Windows 8 for Linux devices", at least I can't find that product on Microsoft's web page. Where did you see this?
Wasn't there this issue regarding the incomaptibility of the cpu?

Right. Win8 does not run on ARM, and WinRT requires a secure boot environment and is only sold preinstalled on devices.

Intel x86 is a general cpu structure, which means 32Bit CPU. You can also use it with other vendor's 32bit CPUs

Windows 10 IoT for tablet

I tried to run Windows 10 IoT from RPi2 on the Surface RT with included drivers from Surface RT. Appears BDOS error CRITICAL_PROCESS_DIED. Maybe someone will change something? To run the system, unpack the archive on the USB-stick formatted in FAT32.
For launch on Surface RT, turn off the device, hold Vol- and press Power key. After turning on, release Vol- key.
Download: http://1drv.ms/1VG4wmt
P.S. You need the latest version of WinRAR;
My bet - missing drivers and USB boot. What device was source of Win10 IoT?
When Win10 for RPi2 was announced I thought about trying the same... sadly I don't own RT device anymore. But as it started booting, seems that secureboot certs are still valid

Check the link to the picture posted above. The answer there is

You can actually install Windows IoT on any x86 tablet, like new surface or the ridiculously cheap Linx1010. On BayTrail tablets you can usually boot the minnowboard image and install all the drivers. For Apollo Lake you have to build your own image of Windows IoT because Microsoft does not provide x64 images, and most computer have 64-bit UEFI.
Check out my guide for detail, i can't post URIs here, but it's blog.quickbird run-windows-iot-everywhere (google that)
If I want to flash Win10 IoT instead of running off of USB, what would I need to do?
Edit: Nevermind -- I saw the youtube video. Anyone know the status on Redstone?
Any update on this? Would love for it to work
I have a Windows RT tablet. I successfully performed downgrade from 8.1 to 8.0. The former owner when sat on Windows 8.1 RT said that he was not updated. That's nice. After creating the second user, I started trying to perform secureboot debug. In the account policy I created another user and assigned to him all the roles, including administrator, User Replicator, etc. After that I managed to run the script and on a black background to press the treasured inscription "Accept and install". After the download, I ran the command that was in the Readme file from the Secureboot folder. After that I started to prepare a flash drive. Build ffu file Windows 10 IoT as a person from the video I mounted through the command DISM /mount-ffu. After that I added the files efi to download, but unfortunately further I did not succeed in doing anything. By the way I install a jailbreak. When you try to boot from a prepared SD card, it ignores it. All the methods are tried. What could be wrong? i may to record video

[WIP] Secure Boot and Linux for Surface RT

I've been informed that this secure boot unlock is only for Windows 8.0 and NOT 8.1. Attempting this on Windows 8.1 can result in a brick! This may also be risky for Windows 8.0 You've been warned.​
We need some serious help and organization. This thread will be dedicated to getting Linux on these Surface RT tablets. We already have the secure boot unlock so why don't we have a full Linux install? I believe it's because all the information is strewn about the internet with incomplete information and broken links. So please keep this thread topic only on the topic of secure boot unlock and Linux booting on Surface RT.
Ok so about the unlock, for those who are asking you can get it here, check the end of the post. To run the secure boot unlock: Move the SecureBoot zip to the desktop, unpack it, and run the script InstallPolicy.cmd as an administrator. (right click and "run as administrator"). In my case it was not working properly because I was trying to run it off a removable usb thumb drive, you should run it from the desktop. Your tablet should reboot then you should get the "secure boot debug policy applicator" install menu with a bunch of warning text. If your RT device has a removable keyboard then please use the volume keys as the "arrow keys" to select accept and confirm it by taping the "windows key" below the screen, I had to do that for my Surface RT. It now should reboot back to windows and at this point you'll want to open a CMD in administrator mode (search for CMD, right click and "run as administrator") and run the command as mentioned in the included readme file.
Code:
bcdedit /set {default} testsigning on && bcdedit /set {bootmgr} testsigning on
Now reboot one last time and your good.
So now what? How do you boot? You can boot anything now by going to settings in the side bar menu, clicking "change PC settings", navigating to "general" settings, and at the bottom of that you should see an "advanced startup". Selecting "restart now" underneath "advanced startup" should bring you to a menu that will allow you to select a USB drive to boot off of. Included at the bottom is also a grub bootloader that's been created for these RT devices and a couple of other possibly related zips.
WE NEED PEOPLE WORKING ON GETTING THE KERNEL TO BOOT! SHARE THIS TO ANYONE YOU KNOW WHO COULD HELP! I was trying to use the source for a related (but not totally the same) hardware known as the "Cardhu Development Board" from Nvidia. The source code for that can be found here, and their own released version of Ubuntu Linux for Cardhu can be found here. I couldn't get the compiled kernel from source to boot but maybe some drivers can be had from that repository.
I DID NOT CREATE ANY OF THESE HACKS, I'm just more a hobbyist learning computers and programming who also loves Linux. Credit seems to go to users @Wack0Distractor, @black_blob, and the folks at ROL for the original hacks. Credit goes to @[email protected]@f for recovering the files, his original post is here, seems ROL had a bit of a issue and a lot was lost but their IRC is still up.

My Surface RT was a used tablet and it came with Windows 8.0 afaik, so everything just worked. I actually don't know what "ci_tools_arm" are but I do know with EFIESP and GRUB you just unzip the contents of just one (take your pick) to the root of a USB drive and they will boot whatever you configure them to boot. "EFIESP" can be used to boot the Windows IOT from https://forum.xda-developers.com/wi...ows-phone-windows-10-mobile-surface-t3365743/ while GRUB can be used to boot ANYTHING, even Windows, so long as you have the proper kernel or files. If you try to boot GRUB you'll just get the GRUB loader screen and the attachable keyboard doesn't work in GRUB, a USB keyboard might though. Right now we need someone to compile a working kernel with drivers for the RT line of devices.
EDIT: Booting stuff requires that you unlocked "secure boot" as mentioned above.

You are going to get people bricked with this method.
DO NOT under any circumstance use this guide if you are on RT 8.1. It will end up in crashing your device and possibly even bricking it (that has been reported). RT 8.1 automatically relocks the secure boot and if you try and install the EFI, it will brick your device.
DO NOT follow this guide unless you are on RT 8.0. Even if you are on RT 8.0, it is still risky.
The kernel for RT is structured differently than a standard linux ARM kernel. That's one of the reasons why linux will most likely not happen for RT devices.

Isn't the device not loading any kernel when GRUB is loaded on a Surface RT? I thought when GRUB was proven to load, that any kernel would load on the Tegra processor, I've seen documentation online where most of the Tegra code (from Nvidia or from Open Source) was ported into the latest Linux kernel.

We could just adapt a Linux kernel (like with Android) if the RT kernel was a Linux kernel, but it isn't. RT blocks different kernels from being loaded (like a locked bootloader, just more complex)

There is Linux (Android) kernel available for TF502T Asus tablet which is almost the same as Surface RT and totally same as TF600T. Here you can still download it from Asus website: https://www.asus.com/us/support/Download/28/1/0/17/32/

I'm guessing there is no known button combo to boot up some sort of debug mode, like the fastboot mode on android devices.
Has anyone seen if there are any JTAG or serial connections somewhere on the board?

Themes / Apps / Mods [ROOT] Limbo QEMU Emulator with KVM acceleration for Tensor Chips

Hi all,
On Android 13, Google enabled KVM support for Tensor Chips model(Pixel 6 / 6pro / 6a). So we can run a Virtual machine at full speed, but there is no APP to utilize this feature.
I modified the Limbo Emulator (QEMU), so it can enable the KVM on Pixel 6 Phones. Due to the limitation of the kernel, the APP needs ROOT permission to access the KVM service(/dev/kvm)
Currently, only VNC is working on this APP, and you can only boot directly using the Linux kernel. UEFI did not work on KVM.
Network functions worked, but you may need to set the DNS inside the Guest OS.
Arch Linux for arm64 runs pretty well on Limbo. It runs even faster than Raspi 4. You can download it from ArchLinuxARM-aarch64-latest.tar.gz
Other Linux can also run on the Limbo, but you may need to recompile the kernel to enable virto-related functions.
See https://forum.xda-developers.com/t/...th-kvm-acceleration-for-tensor-chips.4501665/
