[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
*** This bug is a duplicate of bug 1592229 *** https://bugs.launchpad.net/bugs/1592229 FYI, I fixed the 20.04 official ISO using rufus with a USB drive that my machine could boot. I thought I'd only used Ubuntu official, but apparently I'm using https://github.com/hirotakaster/baytail- bootia32.efi/blob/master/bootia32.efi judging from the signatures. I also downloaded `grub-efi-ia32-bin_2.04-1ubuntu26_amd64.deb` from ubuntu repositories. It's pre-compiled, so I'd imagine it includes a signature (at least I was not bothered for one). I used the tool Rufus to create a USB booting media from the official 20.04 Desktop ISO. I unpacked usr\lib\grub\i386-efi, omitting the "monolithic" sub-folder to my boot/grub folder I then overwrote the .lst files and .cfg files with the same ones as the amd64 image uses Past that point, ubuntu set everything up for me, including detecting and installing `grub-efi-ia32` I had to swap out the heat-sink, because it was a thick piece of what looked like Aluminium foil. I added a Raspberry-Pi 4b heatsink that did not fit on a Pi-4B, and cut out a hole on the back of the tablet. I lastly disabled the swap as it's an EMMC and swapping I believe will wear out the media faster. My only complaint is that the keys on the on-screen-keyboard are tiny and I need to use a stylus, but I don't, I use the device as an 9" portable screen, which I can interact with via micro-USB. To install Ubuntu I did need a micro-usb to usb-A adapter, with a port multiplexor so that I could use a wired keyboard and mouse. Install took longer than 15 minutes, possibly an hour. Tablet boots and I took a backup of the windows install in-case I ever want to go back using gnome disks utility to a micro-SD that got particularly hot, but did not die. Be careful with heat on these things. Wi-Fi works Touchscreen & orientation work micro-SD works There seems to be a 4MB drive that shows up. I backed it up to micro-SD, but it's not a part of the eMMC. I'm assuming it's firmware and never touching it. Intel graphics works and plays minecraft using optifine (works slower without) Sometimes OOM crashes the entire device I do turn off screen blanking external HDMI via microHDMI -> full HDMI works Lack of keyboard and mouse and no detection of primary touch device means the tablet is unusable without at least a mouse via USB If I'm honest, avoid buying these cheap devices, but I would be interested to find out how to contribute grub-ia32-efi-bin for all 64-bit ISO's, just so people can get started. I'd also be interested in automatically enabling the on-screen keyboard for touch devices on intel Atom -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341944 Title: 32-Bit UEFI bootloader support needed To manage notifications about this bug go to: https://bugs.launchpad.net/debian-installer/+bug/1341944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Really wish this could get fixed for 16.10- I'm already running Ubuntu Touch/Unity 8 on my phone, but this bug is keeping me from transitioning my tablet over to Ubuntu. Sure, I can get it working with Debian as it's built into the multiboot installer at this point, but only Unity 8 can truly do the touch interface usably in my experience.

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
This is a very serious issue, at least for me. I bought Asus Aspire Switch 10 E and I've been fighting to install Linux to it. This has been the closest one as a solution http://www.jfwhome.com/2014/03/07 /perfect-ubuntu-or-other-linux-on-the-asus-transformer-book-t100/ , but bootia32.efi is a one issue. I can't make a proper one because I have 12.04 in current laptop (because it is old and due to the graphics I can't update it). I tried also one mentioned behind the link Anyway, I was able to get to the phase where in GRUB you manually define the kernel and then you boot the machine. Everything started promising, but then it stops to error message "mount: can't find root in /etc/fstab". I checked the fstab and it looked OK. But when I checked the /dev directory there were no mmcblk-devices, only in boot-USB had them. I also tried to use Debian-distro which is mentioned in this discussion, but it won't boot up because of the security issue. BIOS of the machine has place where is said that enable all UEFI-boots as secure but I couldn't change it.

As far as other distros go - can anyone confirm if any distros other than Ubuntu have the signed kernel and UEFI bootloader required to ensure Secure Boot can remain enabled on the machine? Not everyone will necessarily be bothered by needing to disable Secure Boot, but some OEMs make it pretty arduous to do so.

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
This as been mentioned earlier in this thread (see comment #7), but just to clarify : * Debian Jessie i386 does work nicely on the Asus X205TA (cf. https://wiki.debian.org/InstallingDebianOn/Asus/X205TA) * Debian Jessie has been working since January 5, 2015 (cf. http://cdimage.debian.org/cdimage/unofficial/efi-development/jessie-upload2/) on the Asus X205TA So 32 bits distributions DO WORK on this machine. In the case of Debian Jessie, the installer works perfectly except for wifi. You just need to update the kernel after the initial installation -- like this for example : sudo apt-get install -t jessie-backport linux-image-686 and you're done. Nothing difficult or special. Not sure why the UEFI 32-bit is such an issue on Ubuntu. The Debian installer has been supporting this architecture for 18 months now. I've been running Debian Jessie 32 bits on an Asus X205TA for these 18 months and all is well. Don't why "fourdollars" is not able to boot Debian Jessie 32 bits, perhaps simply a wrongly formatted image ?

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
@jokker: You can boot 64-bit Ubuntu on the Switch 10 (or any other Bay Trail Atom device) using 32-bit GRUB. You will need to compile GRUB yourself. The easiest way to accomplish this is to copy the 32-bit UEFI bootloader from a GParted LiveCD to your Ubuntu LiveUSB media, turn off Secure Boot on your tablet, and boot Ubuntu. From there you can download the source for GRUB and compile it for 32-bit. You can also leave Secure Boot off and just install Ubuntu using the GRUB from GParted, but I don't recommend this - Secure Boot is an important feature of your computer that aids in preventing malicious code from executing pre-boot (e.g. during initial POST operations). If you compile GRUB for Ubuntu specifically it will use a signed bootloader that Secure Boot recognizes as trusted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341944 Title: 32-Bit UEFI bootloader support needed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1341944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So... it would be really nice if someone that was able to make this work post the steps used to find success. As others have posted-- these atom machines are not going away. I just purchased an ASUS X205TA for $139 and others will sell for $99 very soon. These are great machines for field work with battery life exceeding 11 hours even using Windows 8.1. While I have loaded numerous 64-bit servers-- I have not messed with changing the grub loader and could use a nice step-by-step instruction doc. My preference would be a guide for Mint Linux but I assume that adapting from one base to another would not be impossible. As for an individual compile I assume that takes away the updates from the repositories and in either case care would need to be taken to avoid grub updates. I would even be willing to make a contribution to the person that gets this to work for everyone.

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
I can confirm being able to boot into an Ubuntu 14.10 64bit live usb by manually adding a 32bit compiled grub2 on my Asus x205ta which has a 64bit Bay Trail Atom CPU but only supports 32bit EFI. It was able to install ubuntu until the bootloader part. It installed a 64bit EFI bootloader but that wouldn't work. I then tried adding the same efi I used on the livecd but I just get stuck at grub when I select it via rEFInd. I attempted to follow some instructions online to load linux from grub but was unsuccessful. It would be great to add 32bit UEFI support. My guess is that at minimum you would need to add a 32bit EFI on the livedisk and in the grub2 installation stage add a check for 32bit only EFI and install 32bit grub with correct grub configuration. Everything else seemed to worked fine in the live usb stage when I tested.

Bug #102 deals specifically with the 32-bit version of Ubuntu, therefore this is not necessarily a duplicate of #102. This bug report is about installing 64-bit Ubuntu on 64-bit machines with 32-bit UEFI only. I am unmarking 102 as a duplicate, as that seems to be complicating the issue. All that needs to happen here is the 64-bit Ubuntu installer needs to simply install both the 32-bit and 64-bit Grub UEFI binaries, which UEFI by design supports natively. I have tested this and can confirm that by installing both 32- and 64-bit Grub on these machines, I can boot a 64-bit Ubuntu OS. (64-bit Grub is not required to boot, but the key is that they can coexist in the UEFI directories.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341944 Title: 32-Bit UEFI bootloader support needed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1341944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Actually, it does. It has to call on the UEFI firmware to obtain the system memory map. Then of course, the installer has to make uefi calls to point the boot catalog at grub. So, you booted the 64 bit cd, and manually installed 32 bit grub? And that worked fine, including being able to run efibootmgr?

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
This is going to continue to be a problem. Its breadth will increase as more and more people attempt to install Ubuntu on any Atom-based device. The Intel Atom platform by design uses a 32-bit UEFI environment. These devices ship with 32-bit Windows 8.1 installed, because 64-bit Windows uses significantly more disk space and most Atom devices have limited storage capacity (32GB or 64GB; sometimes as little as 16GB).

[Bug 1341944] Re: 32-Bit UEFI bootloader support needed
I can confirm this affects me as well. I have an Acer Switch 10 and an Asus T100. Both of them have the same Intel Atom 64-bit processor, but require a 32-bit bootloader in order to boot. These machines are UEFI only and have no legacy BIOS support. I was able to get Ubuntu 64-bit installed and running by following the workaround detailed on http://www.jfwhome.com/2014/03/07/perfect-ubuntu- or-other-linux-on-the-asus-transformer-book-t100/ but after careful review, it seems that simply adding a 32-bit grubia32.efi or equivalent to the 64-bit livecd alongside the 64-bit version of the loader, half the problem is solved. Then it's just a matter of making grubia32 a default part of the distribution alongside the 64-bit version. UEFI is designed to load the appropriate .efi for the expected architecture, and because these low-cost devices ship with 32-bit Windows 8.1 to save space on the device by eliminating WoW64, the UEFI on these devices expects a 32-bit bootloader. Linux (including Ubuntu 14.04 and possibly earlier) supports booting a 64-bit OS from a 32-bit bootloader. Anecdotally, I learned from a friend of mine that they weren't able to install Ubuntu on their Core 2 Duo MacBook because the UEFI on their MacBook wouldn't load the 64-bit version of grub. Turns out some MacBooks are UEFI-only, have 64-bit CPUs, but require a 32-bit bootloader just like these newer Atom tablets. I suggested he try following the workaround listed above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341944 Title: 32-Bit UEFI bootloader support needed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1341944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
