Hi guys,
I can't get my Grub bootup fixed and keep landing in emergency shell of grub (not the grub rescue). And after manual boot even update-grub2 or grub-mkconfig doesn't help.
I summarize the error cause:
I use a LVM Multi boot system with UEFI, without Windows, no disk encryption, no secure boot, no (super) fast boot, and i installed Zorin17 /boot (you need separated /boot partition with LVM) on my last open partition with a size of 384 MB - what's too small for the new kernel update to 6.5.0-14 and cause a failure.
So i backup the Zorin17-boot and my manjaro-boot, than i format my Manjaro /boot partition and copy all /boot-Zorin files to the old (formated) 512MB /boot.
Afterwards i change the UUID in my /etc/fstab /boot mountpoint to the new one.
Than i format the old (too small) Zorin-boot and replaced it with the Manjaro boot files and edit Manjaros fstab.
Than i check the mountpoint and go for a second update after the failed with sudo apt -y autoremove && sudo apt update && sudo apt -y full-upgrade with no Errors this time.
Now i reboot (and yes i don't change grub.cfg or update them manually). I land in a emergency shell of grub.
I use this commands to leave them:
set root=(hd0,gpt5)
linux /vmlinuz root=/dev/mapper/vglinux-zorin17
initrd /initrd.img
boot
Cause LVM and separate /boot there is the /boot as root and not /boot/vmlinuz etc. Vglinux is name of the VG and zorin17 of the LVM.
After im back in Zorin i go for sudo update-grub2 and reboot and again the grub-rescue greets me. Efibootmgr show me 1x Bootoption other than Harddrive or CD "Ubuntu" and as reminder before i had ubu-budgie as bootloader (Manjaro had no bootloader installed and evrything got startet from ubu bootloader) With Zorin17 i opt for the Zorin bootloader and i disable the Grub menue timer, so i don't show up (that work before) but cause no fast boot i can enter BIOS.
Can you help me please guys? I don't wonna mess with no real plan.
My grub.cfg is below (after grub2-update with the correct UUID at least under Zorin menue entry for the /boot). And i only change manually to the symbolic links.
Grub.cfg without multi-boot entry or sub-menues (cause length)
