1. Don't know - but I imagine there is a way to do this
2. Don't know.
3. No - but it would be possible to copy a bit for bit image of it back this way - had you taken a backup before it happened.
4. Yes - look in /boot/grub/grub.conf - you will be able to see which drive/partition it is trying to boot from.

  Gentlemen many thanks;

George: The fear Index has risen to the stage where everything is backed 
up - thanks

Julian:    Have got into the BIOS via [F1] at power-up, reset it to 
Default Settings but can't find any place that has obvious re-sets for 
Hibernation/Suspension.
              Loss of function of the 'Access IBM' button (see previous 
post) may provide a couple of clues. Normally this should give access to 
Rescue Partition, BIOS or
              Proceed to Normal Boot but Bug #19634 certainly in older 
versions of Ubuntu blocks the first and last choices which is what led 
me to believe that 'Access
              IBM' was the way to access the BIOS. Further apparently 
any over-write/corruption of the MBR completely blocks its function 
which is the current situation.

Tony:     As to the cause of all this I am sure you are absolutely 
correct - it is almost 100% certain the battery went flat at some stage 
during an Ubuntu (not
             Windows) suspend or hibernation.

     Before applying the nuclear option, is there 1. Anyway of checking 
the content of the MBR against what it should be and/or restoring it 
from the Linux side
                                                                        
2. Why does the Windows Rescue CD only give the option to Run Windows 
(which it doesn't) and not allow a fresh
                                                                        
     Install (which it used to). After all the Ubuntu 10.04 Live Disc 
still allows both choices. Could corruption of MBR
                                                                      
       give this situation.
                                                                        
3. Is there any way of running a Windows install into /dev/sda1 from a 
Linux terminal.
                                                                        
4. Is there any way to see where the boot-loader is pointing and which 
one is the recovery partition

     I am sure these questions (especially No 3) reveal a profound 
ignorance of computer science for which I can only apologise  but then 
this is what keeps me young - well sort of. Seriously though it is very 
instructive for me to dig into this a bit. So far my ill informed guess 
is it is a problem with MBR

Thanks again

Chris

However this doesn't explain why the Windows recovery CD won't boot. Another possibility is that somehow the grub bootloader is pointing to the wrong partition for Windows - possibly trying to boot from the recovery partition? Either way if you have the Windows recovery disk it might be best just to wipe the partitions and start again - after backing up any files from the windows partition using Ubuntu.
