Attempt to read or write outside of disk ‘hd0’

Asked by Luis M.Jacinto on 2021-02-19

Installing 4 times Ubuntu 20.04 and after few days when Booting it stops
with errors and one is “Attempt to read or write outside of disk ‘hd0’”.
I use live USB 20.04.1 and install and run Boot-Repair it reports the following.
“Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI
firmware from live-CD (or live=USB) that is compatible with UEF booting mede.
For example use a live-USB of Boot-Repair-disk-64bit”
Don't know what I should do can some one explain and help me fix this.
Thank you

Is this a dual boot or is Ubuntu the only OS on the system?

Ubuntu only OS

Did you try to install with compatibility mode in the BIOS (legacy) as well as secure boot?

No I didn't it was just insert USB stick and install, do I have to reinstall?
Need directions to modify the BIOS.
Thanks
