I does not have a lot of setting in the BIOS for UEFI.
I’ve tried to follow UEFI - Community Help Wiki instraction and not success:
- I created 1MiB partition after my EFI partition and mark it with bios_grub flag;
- Then follow instaruction by Unticking the “Separate /boot/efi partition” option;
I does not get any success.
I suggest that upgrade introduced some not compatible changes into the system (maybe there are some Missing modules as mentioned in the boot messages)
I decided to reinstall a system on an existed partition but encounter that Installer does not support mounting system to root without formatting a partition. So I shrink system partition and created a new 100MiB partition for /home files. Than I cleaned large files (sudo baobab /mnt/os/home) and copy files with rsync -avu --delete "/mnt/os/home/" "/mnt/home" command (use this https://unix.stackexchange.com/questions/203846/how-to-sync-two-folders-with-command-line-tools).
Thank you for your help
