Kubuntu won't boot

[Nicholas Saunders]

well, just coming at this tangentially:

if a live USB drive or similar works, then probably your hardware is mostly
fine.  Never hurts to run a RAM test.

Anyhow, if it's possible, swap out the hard drive.  Can you pop that hard
drive into another machine?

A more technical approach would be, I think, to delve into GRUB.  That
however, is beyond my skill-level.

For general RCA (Root Cause Analysis) I suggest trying to isolate the
problem.  Probably your motherboard and RAM are fine.

GL and HTH,

Nick
