Hi I’m having my proxmox boot loop these errors and I have no idea how to fix it, it starts out as
Unexpected return from initial read: Device Error, buffers ize 0 Failed to load image BB:


Device Error start_image) returned Device Error


Then to


Failed to open |EFI\proxmox\grubx64.efi - device error Failed to load image ??: Device error


Start_image () returned device error

I have tried everything and when I try to boot repair it from a live USB I get the error “grub-efi purge is cancelled”

Is my nvme drive fried or is there a way to fix this?




Then lastly Start Image failed: Device Error
 
Firstly try booting your system with the Proxmox installation ISO USB.

Select Advanced & then Rescue Boot .

If after that your Proxmox instance boots correctly - you will then probably have to fix the bootloaders & EFI partitions etc. for a permanent fix.
 
if the rescue mode doesn't work, then booting a live CD, mounting your root partition and chrooting inside to fix it should be possible - what kind of setup are you using (ext/xfs on top of LVM, ZFS, BTRFS?)

I was able to get that to work but when I try to use the command update-grub I get the error, cannot create /boot/grub/grub.cfg.new: Directory nonexistent. Any ideas where to go from here?
 
please post the output of "efibootmgr -v"

I’ve also tried changing the boot order around and have been getting the same error as before but am able to get into the grub recover tool with boot option 0003
 
I'm not exactly sure what is going on, but I suspect you have Secure-boot enabled in the BIOS. I would disable it.

I don't recognize that "SHIM64.EFI" , AFAIK that should be "SHIMX64.EFI". The fact that it is wrong is perplexing.

Again your output contains spelling errors etc. Maybe you are typing it out manually or using OCR?

What does pveversion -v output? What does findmnt / output. What is the history of this node? What version of Proxmox was initially installed?

You still haven't told me if you're BIOS is expecting a secure-boot. (The above output of bootctl is different than normally shown; "Secure Boot: disabled (setup)", not sure what to make of this. Mine, that has secure-boot disabled shows; "Secure Boot: disabled (disabled)").

I’m not sure if my motherboard has a secure boot, in all honesty I’ve been searching around the BIOS for and option to disable it but I can’t find any option for it. Or any option that could correlate to a secure boot. My motherboard is a Gigabyte GA-H110N 1.0 if that’s any help to you.

Also sorry for the spelling mistakes I’m currently just taking a picture of my screen and having it copy and paste like that. If you have a better solution please let me know and I will switch over to your method. But for the output pveversion -v I get

So it appears you have a regular ext4 install.

I don't have that MB, but lets assume that since you can't find that setting, you have not enabled it at any stage. However this will only depend on what the history of that node is (which you have not provided).

What I would do in your case is the following (after rebooting into Proxmox):
apt install --reinstall grub-efi-amd64

The history of this node is I have had it for 6 months with no problems running 2 vms, with one being Ubuntu desktop and the other Ubuntu server. I have not updated anything and have just left it be when I started having having this issue when my internet went out. I’m assuming that some update was going on and was not able to complete and ended up corrupting the grub file.

Also the command apt install —reinstall grub-efi-amd64 gives me.

Assuming you do not have a Proxmox subscription, you need to enable repos for the no-subscription repo.

Please provide output for the following:
Code: 
cat /etc/apt/sources.list.d/pve-install-repo.list

cat /etc/apt/sources.list.d/ceph.list
