I know this has been asked a lot of times before and I have tried almost all those fixes the commands like set root=/dev/nvme0n1p1 always fail tried both boot-repair disk's recommended repair and advanced (only selected to purge grub before reinstalling it)

I have reinstalled OS 3 times with same issue every time, and I tried all the fixes, but everything failed.

Note: it's not dual boot and i have only one nvme ssd

Also when it boots normally or shuts down it displays a black screen for a second which says something like elantech failed to query capabilities

Currently I am on 4th fresh install with the same problem and hv only run boot-repair once. logs- https://paste.debian.net/1211042/

  • Follow MY Answer here https://askubuntu.com/questions/1256686/cannot-install-ubuntu-20-04-on-mac-mini-2020/1265490#1265490 and yes you have to set ROOT and the RAM like you already have but the trick is, after you get to the >reboot step you MUST fix your grub file or when you reboot it will go back the UUID problem again. – darth_epoxy Sep 09 '21 at 09:12
  • @darth-epoxy thanks! set root command failed and the ls (hd0,gpt1)/boot/grub says grub folder doesn't exist but the answer below yours seems to have fixed the issue. – odd steak Sep 09 '21 at 16:55

update for anyone with similar problem : turns out this was a known issue with dell BIOS it was patched in a bios update . updating bios fixed it(you can find the update file in dell support page for your model just mv the exe file to /boot/efi folder, reboot to bios and click update bios > flash from file > select the exe file you downloaded > update bios)
