Hi All,
Proxmox 7.1 system is up and running. Last night run upgrade to latest update available ( non production updates)
After reboot the error message Grub loading .. error: disk 'lvmid/<number> not found and my system boots into grub rescue.
ls hd(0) -> I can see partitions

Question: How to fix this boot issue?

Thanks in advanced

Hi,
you'll likely need to use a live CD. See this thread (which might be the same problem) for more information.

I booted ProxMox in debug mode.
Type command like documentation # proxmox-boot-tool status
reply /bin/sh: proxmox-boot-tool: not found.
90% of all command I want to use are not found.
What is the purpose of debug mode?

I checked this threat -> result ... GRUB .. reboot and select proper boot device.
Partition not bootable ?? -> boot from EaseUS Partition Master -> looks good to me ...
What is the next action?

The commands should be available after you chroot (see here). Then you can try to fix it by changing something on the LV and run update-grub as described in the other thread.

I did not succeed in restoring grub but succeeded in moving the data from non bootable HDD to NAS .
