Why not tell us exactly what you did, and post your /boot/grub/menu.lst so we can see what you see. If we know what you did and how you did it, we can probably tell you how to fix it without a re-installation.
Your Too Kind old-polack, I appreciate your offer of Help, thankyou.
If you can get your head around this it may be of benefit to our Forum knowledge base, not sure if this is a great place to post the exact details, though we could start an appropriately located Thread, or move this post ?
1.) I Dual Boot. WinXP, pclos MiniMe 2011.06, that wasn't a clean install either (!), it was fully updated incrementally through Synaptic.
2.) Had Illness and on some strong Meds, uhum.
3.) I use Win at work, so don't login at home to win often, felt should do some housekeeping however.
4.) To cut a long story, was having a look at a Partition Manager programme in Windows; for the life of me and I blame it on not being well, and tired, you know; I resized the root partition on pclos Minime 2011.06, as it is on the C:\ Drive, where Windows lives and crazy I know, this was not wise.
5.) The programme allerted me I may have to "adapt" the linux bootloader, but my finger had slid the resizer bar, apply, and I'd stuffed up.
6.)Once rebooted I got a error, GRUB error- 17, vaguely from memory.
I am interested in what "could" have been done, as you suggested posting some info, I'll continue, maybe some may learn something also...
*I put my (OLD)Live CD of pclos Minime 2010.12 in tray and rebooted.
*Entered pclos as "guest", was looking for a clue, ( as I know now somehow find /boot/grub/menu.lst
? ) all a bit blurry, but eventually felt my only option was to install this version; could see Windows drives, and knew I still had most of 2011.06 on my Hard drive, but was lost.
*Installing off of the Live CD Minime 2010.12 gave me back a grub bootloader so I could boot into windows, restore the MBR (Master Boot Record -Win) which I have safely stored, and yeah the rest is history.
*Deleted the six Linux partitions,
; have downloaded.iso & made a Live Cd of pclos LXDE Mini 2011.06, and waiting for a bit to get my head back together, and finish antibiotics.LESSON:
If your a bit spaced out, Tired, whatever don't put yourself into a position so vulnerable as I did. I know, I'm an idiot !
It's with great embarrassment I post this information, which will give all a great laugh, I'm sure
