Hi.....can anybody assist me in my latest screw-up?

Had (have?) Win xp on master drive + logical drives containg personal stuff.

Had (have?) slave drive with SuSE + xandros + some 20 GB of unpartitoned space.

Everything was working hunky dory until I downloaded an upgrade for a prog in xp. Told to reboot upon which I had a screen full off "99"'s. Blindly tried a number of things out of desperation 'cos I haven't a clue, all to no avail.

Had a few drinks and decided to install a Mepis os that I bought but too cowardly to do anything with; as a last resort. Anyway, it went well and as you see I am 'back' but the boot up shows only win and mepis and I would dearly like to be able to acces particularly my xandros install. Any suggestions please? If so I would be really, really, really, grateful for any guidance especially if explained simply 'cos I'm a simpleton......thank you!

I think the Xandros CD 1 has a rescue mode, by which you can reinstall the bootloader.
Boot the Xandros CD. A message will be displayed to press shift for advanced troubleshooting options.
In the menu displayed, select reinstall bootloader.

Without you posting some sort of details about your system it's impossible to give you any help at all. Partition tables, bootloader config, that sort of thing.
