Aliens abducted my system? ;) You can discount the kernel since, as far as I understand when you have the problem all you get is grub> I.e. you have only got to the grub prompt - The kernel only comes into play *after* grub, once grub has found the kernel you selected. The fact you don't get that far means grub is unable to find the kernel you requested (or its own config file perhaps ?). This means grub cannot read /boot for some reason. >From your list this leaves - hardware - BIOS - GRUB - user and from the details in this thread I cannot discount any of the above (although personally I would consider GRUB the least likely) You say you have installed this system a few times - How hard would it be to just install one more time, but this time with a /boot at the start of your drive - This will either a) work, so all is fine or b) not work, proving something or other about the problem.
