- Since I have installed Ubuntu 20.04 my PC comes up with the grub boot screen where I'm supposed to be able to use the keyboard to either resume with the boot process or carry out some other process, BUT, the keyboard appears to be dead since grub does not respond. This is not a dual boot system.emphasized text
- The only way to get the keyboard to work with grub is to disconnect the hard drives and switch the PC on. I then go into the BIOS and simply save and exit (making no changes) and then switch the PC off. I reconnect the hard drives and switch on the PC. When it gets to the grub screen and I hit enter, or arrow keys, grub responds immediately. The next time I boot up my PC, without disconnecting the hard drives, grub does not respond to the keyboard.
- I also found that unless I disconnect the hard drives I cannot get to the BIOS settings using the usual "delete" or F2 keys which is something you are supposed to be able to do.
- I've tried to change "auto" settings to enable and visa versa but none of these changes made any difference to the problem, which I didn't have with Ubuntu 18.04. I even disabled UEFI.
- Does grub dynamically store BIOS info on the hard disk that is then used at boot time by the OS, in this case Ubuntu ? PLEASE HELP !
BIOS
GIGABYTE H77M-D3H
You have BIOS version F10.
There's a newer BIOS available, version F12, and it can be downloaded here, for rev 1.0 motherboard, or here, for rev 1.1 motherboard, or here, for rev 1.2 motherboard.
Note: Confirm that I have the correct web pages for your model #.
Note: If you have a different revision motherboard, it'll require a different download.
Note: There's actually a BIOS version F14, but it's a beta BIOS, and I wouldn't recommend that you install it.
Note: Have good backups before updating the BIOS.
