I need help in understanding GPT, MBR and GRUB.
I'm having problems installing a Linux on a SATA disk.
The disk checks out as clean and formatted under HUTIL
2.03, and I think the problem must be with the MBR or
When I switch on, I get the BIOS splash screen, so I
guess that must be OK.
Then I get a text screen with
NVIDIA Boot Agent 244.0538
CLIENT MAC ADDR ...........
DHCP ... (progress indicated)
and after a couple of minutes,
PXE-E53: No boot filename recieved
PXE-M0F: Exiting NVIDIA boot agent
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I typed the error codes into Google and it seems that
these are Windows messages. I did have XP on this disk
previously but wiped it.
Here's what I don't understand:
==> If my MBR/GPT/whatever has been corrupted by
XP (or anything else), how do I install a new clean one?
===> The wikipedia page about GPT,
describes BIOS and MBR as `relics' but my impression
is that most rescue software doesn't consider GPT.
For example sysrescuecd has tools for correcting
partition tables and installing GRUB but I don't
see anything about GPT. Can I just have MBR and
GRUB as in the past, or do I have to use GPT now?
Wikipedia says that GPT includes MBR for compatibility with old systems, but how do I tell whether my box has GPT present or not?
BTW I don't need to rescue data. What I need to do
is get an OS working on the disk.
Thanks in advance.
