Boot Error


Hi everyone, I'm a supermega newbie who knows little if not nothing about pcs and Operative systems. That said, I have the following problem: yesterday I bought a Serial Ata Hard Disk (that'll be the third hd I have on my pc). After disconnecting the other 2 hds and installing Mandrake linux 10.1, I reconnected the other 2 hds (1 with Suse 8.0 and one with Windows Xp). Unfortunately I haven't eversince been able to boot again Windows Xp as everytime I try to, I get a message which tells me something like: "Boot Error, it's impossible to launch you O.S.". I have also tried to mount my Windows hd on Mandrake but it has all been unsuccessful. I am very confused since before the error ocurred I hadn't been messing with partitions or anything. I'm really desperate because I have a lot of crucial data on that HD so I really need to find a way to recover the data in one way or another. I would be extremely grateful if anyone could help me (and possibly using a non too specific kind of language as I wouldn' t be able to understand it).
Thanks to everyone.

If you disconnect the Mandrake disk, are you able to boot (the same configuration as there was before MDK installation)?

No, it's useless. If I try to boot Suse it works but if I try to boot Windows it doesn't. I've also tried checking if all the wires were ok and I know for sure that that's not the problem. I really don't get what's wrong. The really odd thing is that if I try to mount the hard disk with Windows Xp, I get this freaky message which more or less says (I'm translating from Italian so probably the message won't be 100% accurate, forgive for that )

mount: fs type wrong, invalid option, superblock on /dev/hdb1 damaged, or too many file systems mounted

But I have no idea what all this might mean. I just really hope there's something I can do to get my data back ;__;

linux loader or lilo bootloader overriding windows

If you are using software that creates patitions it may infact hide the other operating systems on hard drives. For example i had windows xp pro on c:\, then loaded linux to a drive partition magic created for it. The linux loader or lilo then jumps up in front of windows boot and if you havent configed the lilo correctly then windows wont be one of the options. Even if you had the option to choose windows because the c:\ drive is hidden windows will most likelly not operate properly or even keep restarting because files are missing. Go here for help http://www.control-escape.com/linux/lilo-cfg.html. you need to run the linux prompt and unhide c:\ which im my case typed
Unhide /dev/hd0
c:\ = /dev/hd0 and e:\ = /dev/hd2 etc...
type "help" in the prompt for command list. Once the partition was unhidden then windows could be booted using,
(hd0,hd4)
chainloader +1
Hard to explain really supose u have to be there to understand, i may have some of this wrong being in a hurry and all.

Using multiloader GAG is much simplier. just try first to boor GAG from disket without saving onto HD. If works perfecto, then use HD boot

I tried to use GAG but after trying to add the partition I need, and boot from it, I get a message saying that the boot sector is either missing o damaged.

floppy or LiveCD start. Try to fix with lilo damaged bootsector. Actually under KDE in admin mode lilo can probe before writing new bootsector
If this does not help
again boot with floppy or Live and
#fdisk /mbr
Read manual before applying last command
If used incorrectly may cause damage to HD
