Can you first try, using the terminal,

Code:

dpkg-reconfigure grub-pc

Code:

sudo apt update

sudo apt full-upgrade


Is it uefi ?
Is it dual-boot?
Have you been using grub-customizer?
where is grub installed ?
Are you proficient enough with the terminal commands?
There is plenty of information on AskUbuntu.

/usr/sbin/grub-probe: error: failed to get canonical path of `/cow'.

Did you try that update on the installed system ?
If it is the live system this is normal as it does not use grub and tries to detect the live system itself which has to fail.

UEFI is the unified extensible firmware interface (aka BIOS) on newer systems.
https://en.wikipedia.org/wiki/Unified_Ex..._Interface

Dual-boot or multi-boot is running more than one OS at a time on a system switchable at boot time.
https://en.wikipedia.org/wiki/Multi-booting

Looks like your trying to upgrade a persistent USB install media (rescue USB).
This is not possible as the OS portion is still written to the media as a read only file system.
Only the user data (AKA home directories, etc.) are stored on the persistent FS.

UEFI is a replacement for BIOS, the efi is a name/label of the partition where UEFI boot files are stored.
Dual boot means more than 1 operating sytem on your HD.(this will determine where your grub is installed)
Can you inform as to Leszek's question.....Did you try that update on the installed system ?
If it is the live system this is normal as it does not use grub and tries to detect the live system itself which has to fail.
In other words are you trying to update before Maui2 is installed to on your hard drive?

Good evening,


apology from my English...

Now I write you via USB 8Gb "Persistent" Linux Mint(6 months is done all upgrades), because Maui USB 8Gb "Persistent" do not start! black screen with 2-3 lines, write cannot boot.
I done what that you write :
1) sudo dpkg-reconfigure grub-pc (error, not install)
2) sudo apt update
3) sudo apt full-upgrade
4) sudo dpkg-reconfigure grub-pc (installing)
5) shutdown(not to boot)

I have 64bit 8.1 Windows is UEFI, with internal HardDisk and 1 USB disk for backup.

Is possible to boot or must to reinstalling?

You cannot upgrade kernel or grub on a persistent USB live stick. 1st grub isn't uses.
2nd kernel updates means you need to overwrite the vmlinuz and initrd.lz files with the new versions.

So if you upgraded kernel that might be the issue here. So reinstall would be the easiest solution.
