I try to update my computer that was on kernel 5.2 and it seems to remove the kernel and download the kernel 5.5 but for some reason the grub was stuck on 5.2 so when it boot I get the error that the kernel 5.2 was not found.
I try to repair the grub following the wiki instruction but no more luck I got the update-grub stuck with this error:
grub-probe:error:cannot find a GRUB drive for /dev/sdb1
/dev/sdb1 is my liveUSB partition
Now when I try to boot I have nothing at all no grub, no message
Not sure where to look now.
