[ubuntu-uk] Disk Rescue!

I'll try to be sucinct as possible, but also explain as fully as I can.

Booting up, I get the grub menu.  Choosing any of the 4ish(?) Ubuntu
choices (exept restore versions) results in hung system. Choosing XP
results in hung system.  Choosing one of the restore options results in a
scrolling screen of text, so fast it is difficult to pause and read but I
do recall some bad messages relating to DMA.  I can get to grub prompt but
I haven't much of a clue from here whether this is a good thing or not.

Portege does not have floppy drive - just DVD.  However, I did try
re-installing XP but it hangs when it comes to trying doing anything with
the hard drive.  Tried a number of live CDs again in an attempt to use
partitioning software to sort it all out, but to no avail.  Even
attempting to delete partitions - it just hangs.  Latest attempt was using
a live version of Gparted but again although it can see my partitions any
attempt to change them causes problems - its as if they are write
protected; but no feedback from tools says this.

I'm investigating whether I can repair the MBR - if in fact that is wrong.
 Thought I'd found some utility to do this but it doesn't appear to be
part of any distro I have.

All very frustrating.  As I say - any tips would be appreciated.

Not sure I understand what the problem is! Are you able to access the
disk at all? Do you get warnings, etc. when you try to boot? Do you have
an OS that can be booted from the disk? Not long ago, I munged up a dual
boot, and to get WinXP back, I had to use my rescue Disk, open a command
prompt and run "fixmbr", which killed grub, but gave me back my XP.
Perhaps you need to do something similar?
