I am having issues booting and end up in a grub rescue shell.

Searching around the web, i have found some commands to get a bit more information about my system.
Running sudo fdisk -l gives

From which we can see my main drive is /dev/sda and the root and swap use lvm.
The /dev/sda and /dev/sda1 have the boot flag. It is pretty much a standard unbuntu installation. The /dev/sdb is the usb drive i am using right now to run my computer.



To me, all seems fine and i am out of idea on how to get my desktop back. How should one approch this problem to solve it?



Thanks,

  • Dropping a bounty on this. I have this happening on a server with an HP Enterprise SSD in it. It happens very frequently when rebooting. I have the luxury of wiping the install and reprovisioning the disk with ansible afterwards as this is just the root disk, but this keeps reoccurring. It's not a one off problem. And it's 18.04 specific. I would like a way to recover without a wipe.
