[Bug 1863434] Re: 20.04 grub menu not visible

[Salvador Ortiz]

seeing this issue on an HP Pavilion model 3507c slimline desktop PC,
booting via BIOS.

booted in to Grub menu immediately after installation and after initial
power cycling. Subsequent reboot skipped grub menu and hung at system
partition verification stage of the boot process.

Shut down machine for troubleshooting and it booted into the Grub menu
once again. Subsequent reboots and power cycling once again yielded no
grub menu and are still hanging at the system partition verification
stage of the boot process.

Downloaded and installed Ubuntu 20.04 image only 3 days ago. Uninstalled
Gnome, GDM, and related packages to run as a headless machine (Ubuntu
Server installer seems to crash for me on most PC's and virtual
machines). Also set up two USB drives to run within a software-based
RAID 0 array.

When it does boot into Grub it leaves me at a terminal login, as
expected, but this doesn't happen anymore regardless of how many times i
reboot or cycle power. I've cleared my BIOS settings, tried booting from
installation medium (video display was corrupted, making it difficult to
install in the first place).

No options to recover the machine, access it's disk, etc. Please help!
