Cannot install Snakeoil on UEFI-only NUC - scskam - 08-Aug-2020
Hi there,
I am interested in Snakeoil and have purchased an Intel NUC7CJYH with a fanless chasis to try it. This NUC doesn't only legacy BIOS boot so UEFI is my only choice. I tried both burning the Snakeoil ISO image to CD-ROM and creating a bootable USB using Rufus. CD-ROM could boot up and I could start the installation. For USB, it always stops at grub-rescue and I had to issue the following commands to make it proceed to boot:
set prefix=(hd,msdos1)/boot/grub
set root=(hd0,1)
insmod normal
normal
For both cases, I could install to my SSD without problems. However, when booting from SSD, the following error is displayed:
error: kernel doesn't support EFI handover.
Loading initial ramdisk ...
alloc magic is broken at....
I have tried replacing other Snakeoil kernels in the USB and performed the installation again, the result is the same. I have also tried installing the SSD on another NUC supporting legacy boot, and then moved it to the UEFI NUC and used Boot Repair as suggested in another thread. No luck so far. Searching on the web suggested that the following flag should be set when building the kernel:
CONFIG_EFI_STUB=y
Any chance that a kernel can be built to support the UEFI boot? Many Thanks.

UEFI boot works here but I had to boot Win 7 and clear all partitions prior to installing.
You want a cleared drive formatted to Fat32 or Ext4...
Reboot and install works as expected. :-)

Yes..I did that over and over again on a thin client with UEFI and Snakeoil install failed every time.
Finally I installed Win7 and at the drive allocation prompt I deleted all partitions (including the reserved and UEFI boot) then rebooted and was able to install Snakeoil.

Hi Bromf,
Thanks for your reply. To ensure the partitions and their contents are right, I first installed stock Ubuntu on the SSD, then resized the partition to free up some space for installing Snakeoil OS alongside with the stock Ubuntu. I can choose inside grub to boot stock Ubuntu (which boots up ok) or Snakeoil OS. The same error message displayed when Snakeoil kernel boots up. So the problem is the Snakeoil kernel not built with UEFI fully turned on.
As said, there are suggestions that the following flag should be turned on when building the kernel:
CONFIG_EFI_STUB = y
I just checked the config file released with one of the customized Snakeoil kernels, this flag was not set while other EFI flags are set:
CONFIG_EFI_PARTITION=y
.
.
CONFIG_EFI=y
# CONFIG_EFI_STUB is not set
.
.
Hopefully the UEFI support can be improved by adding this flag back. Many thanks.

RE: Cannot install Snakeoil on UEFI-only NUC - agent_kith - 10-Aug-2020
Check your BIOS and look for anything that says "Compatibility Support Module", can you turn on legacy support mode?
Technically, the problem with the ISO is it will not boot in a EFI environment, but the OS itself should be fine (as long as your computer works with unsigned boot). After the install, start a command shell, and try this and see if it works?
1. After install, start a command shell.
2. Changeroot to remount the install edition as your root. I can't remember offhand what the path is, but you can find it in df or mount, then run chroot
Code:
chroot /path/to/your/install/partitionCode:
sudo grub-mkconfig -o /boot/grub/grub.cfg
sudo grub-install --target=x86_64-efi --bootloader-id=grub_uefi --recheck grub-mkconfig -o /boot/grub/grub.cfgRE: Cannot install Snakeoil on UEFI-only NUC - scskam - 10-Aug-2020

There is no legacy boot support nor CSM smode in the bios. I have disabled secure boot and S3 related settings, the UEFI boot cannot be turned off and no legacy boot available in the BIOS menu.

3. Run the following commands and see what happens:Code:chroot /path/to/your/install/partition

[code]
sudo grub-mkconfig -o /boot/grub/grub.cfg
The Snakeoil automatically rebooted after installation so I had to change to seed file on the USB to disable reboot. The partition in of the newly installed OS is /target.
Here is the output when I issued the suggested commands. Many thanks.

RE: Cannot install Snakeoil on UEFI-only NUC - agent_kith - 10-Aug-2020
Almost certain you don't need to install grub_efi... Because Ubuntu will detect your system is using EFI and install the correct bootloader.
Correct to chroot to /target. That's the correct directory.
Once you've done that, can u run
Code:
sudo mount /devand then run this command again (ignore grub-mkconfig for now):
Code:
sudo grub-install --target=x86_64-efi --bootloader-id=grub_uefi --recheck grub-mkconfig -o /boot/grub/grub.cfgRE: Cannot install Snakeoil on UEFI-only NUC - scskam - 10-Aug-2020

RE: Cannot install Snakeoil on UEFI-only NUC - agent_kith - 11-Aug-2020
Hmm.
After you have chroot to /target. Try and run this:
Code:
mount udev -t devtmpfs /devMake sure your snakeoil partition is at / before you run the above command, and also grub-install.
Still waiting for my network card to get here.. Once it's here it will be easier for me to work out EFI issues. Having said that, all my computers have CSM so I'm not too hopeful.. At least then I can properly start work on getting the new ISO out. Hopefully the latest Ubuntu will have better EFI support. It's been almost 3 months I think.. Almost takes a season for my network card to get here, and I'm not even sure if it's a legit NIC or not.
