[BOOT PROBLEM] - Since (uncomplete upgrade)

[michellabrie404]

Hello, people of the global internet


I think I had an issue with the update (probably not completed), and since then, I have a problem: it no longer detects a boot on the system. I'm quite annoyed.

For information : Computer don't detect OS


I have tried several things by booting into "systemrescue."


For your information, the partition mapping is as follows:

• /dev/sda1 does not have a defined FSTYPE.
• /dev/sda2 is of type VFAT (Fat32: basically, this is the EFI boot partition).

I have attempted several manipulations, but none have worked so far.

Chrooting the system with /dev/sda2 mounted to /boot, and then /dev/pve/root mounted to /.

I tried update-grub and grub-install without success.
fsck does not return any errors on /dev/sda2, for your information.


Following this guide:

I don’t know what else to do. Do you have a solution, please?

Thanks ^^

Chrooting the system with /dev/sda2 mounted to /boot, and then /dev/pve/root mounted to /.

that's the wrong way round. you first need to mount your root partition somewhere. then mount the ESP into boot/efi in that mountpoint.

once you've done that, please chroot and give the output of

"find /boot/" and "efibootmgr -v"
