error attempt to read or write outside of disk 'hd0' / Kernal panic

[gildal]

Using VirtualBox 5.2.8
Host is Windows 10
Guest is Ubuntu 16.04

Been using Virtual box for a week and it suddenly wouldn't boot up properly. I get an error that reads 'error attempt to read or write outside of disk 'hd0'' and then give me the attached screen.

I'm new to Linux so I have no idea what to do.

A CRC error normally means a hard sector error, so it looks like it's time to replace the host drive. At least that would be my choice. It may be possible check it for errors and mark bad sectors as unusable.

Alternatively it's what the error message says: bad code in the guest is attempting to read sectors that don't exist on the virtual drive. In that case you'd need to ask on a Linux forum why that would be the case.
