Sadly Ubuntu's version of GRUB 2 has an additional problem (fails to boot Linux) and should be avoided. Consequently, configuration files are used to automate booting and pass kernel command line parameters: Touch and Type Covers also do not work on the Surface RT in these applications. Unfortunately a bug with the Surface RT's UEFI implementation stops the display from working with most efi applications unless specifically patched (or the EfiFileChainloader is used). On a USB drive they are normally given the name /EFI/Boot/bootarm.efi as this is the fallback file loaded by UEFI. These are usually stored in an efi folder on the boot partition of a drive. Pre-built '.efi' binaries are available by following the links. The Surface RT can use GRUB 2 or UEFI shell as a bootloader. The root filesystem can be placed on eMMC, USB or microSD card. UEFI bootloaders need to be placed on the internal eMMC or USB drive. Please ensure you download image, modules and dtb from the same kernel version number/date.

Finally, remove golden keys if you intend to dual boot Windows or install Windows at a later date. Once you have a completely fresh install you can use the jailbreak usb to install golden keys and then run yahallo. You must download an image as the recovery partition will not work for this. The easiest way is to download and install the official 8.1 recovery image for you device as these pre date the patch. Microsoft patched the golden keys exploit, but fortunately for Tegra devices this can be reversed. For UEFI booting it is recommended to install yahallo. Due to its added complexity it is discussed at the end of this page. APX currently offers considerably better performance, but it has the disadvantage of always needing "jump leads". TrustZone is still active, but recent changes to the Linux kernel (~5.11) allowed this to be automatically avoided.Ĭonsequently, the Surface RT has two boot options: APX or UEFI. It can be applied with the help of golden keys.

Yahallo is a new (2020) Tegra exploit that effectively turns off secure boot permanently.

Secure boot and memory TrustZone are still active. It allows a self-signed Windows boot manager app to run and in turn an UEFI app such as GRUB 2. Golden keys has been available since late 2016. This removes all the restrictions of the UEFI firmware.

You may find community builds such as the Ubuntu MATE Raspberry Pi images.Īlthough it is technically possible to install the full Ubuntu Desktop via Ubuntu Server/netboot, it is highly recommended that you install one of the lighter desktops such as Lubuntu, Xubuntu or MATE. A general (and hugely over-detailed) installation guide for this can be found here. Much of the Raspberry Pi Ubuntu Server documentation applies to the Surface RT.įor 20.04 there is also still the netboot installer. The only official and supported Ubuntu armhf (32-bit) media are the images for the Raspberry Pi.
