hi guys

I have a box on which UEFI boot has gone haywire and instead of boot it power the box down, that is before even going to grub2. (displays some error message) I if change to BIOS boot then I can start Centos' rescue - my question is: how can I rescue, re-build grub so it would boot from tradition BIOS?

If the OS was installed with UEFI enabled I would go back to UEFI mode.

Then re-add your OS boot configuration within the BIOS setup screen.

Most motherboard manufacturers detail this process on their website where you browse the disk to select somefilename.efi and give it a label “CentOS”.
