[nflug] GRUB error 18

[Cyber Source]

Whatever the bios is told as a boot device, if it's a hard drive, it 
will go to "first" partition on that drive that has a "boot" flag (fdisk 
-l), it will be the partition with a "*" declared.
First off, I would suspect a problem with the CHS (cylinder,head,sector) 
geometry that the drive has or is being interpreted by the bios as, to 
the kernel.
Second off, I would think it's how the stanzas are written and the 
UUID's (always a problem I've seen) are being used. Try changing to the 
actual drive /dev use.
Tell me those things and I'll tell you my reasoning later, if 
applicable, sorry lazy typer.....
