ok ready for the fun. I'm an fairly experienced knoppix/linux guy, done tons of knoppix installs,so I don't think this is something obvious

parents get a new compaq box, 120gb hard drive, running winxp sp2 (yea it came with sp2, kinda cool?)

hating to see it go to waste, I ran knoppix 3.6 on it, did knoppix-installer, qtparted the whole bit. I gave linux a mere 7gb after the resize.

lilo loads fine, linux boots fine, but windows refuses to boot with:

Code:
A disk read error has occurred
press ctrl-alt-delete to restart
normally this seems to be associated with hardware failure in all the places I've looked, but according to this forum about using raid in winxp,there has been some modifications to do with the cluster size of the windows partitions (i think,im no raid guy.).

apparently xp sp2 doesn't like anything more than 16k clusters whereas pre-sp2 it didnt care.

somehow this all relates back to qtparted's resizing of the ntfs partition.

I can read the partition fine inside of linux, but can't get windows to boot to it either from lilo or straight up mbr.

I tried different arrangements of lilo and bios settings, and tried restoring the backed up mbr with no luck. I'm wiping the box as we speak (cause theres no data on it, its brand new + parents about to kill me), but if this is a problem that occurs with winxp sp2 we need to figure out what is going on before people start toasting their xp installs

(involuntarily toasting xp == usually bad)

any ideas?
