most probably, the win xp setup files must be in a folder on the cd....
suppose if the files r in a folder named WINXP
if u have a cd-writer, u can create a bootable disc.
if u can, burn ONLY THE FILES contained in the folder WINXP to another cd (do not burn the folder itself) so that the files will be directly available from the cd.
no rajesh, u cant run the winxp installer in DOS mode....either in windows or thru direct boot.
1. boot with DOS (98 bootable)
2. load smart drive (smartdrv.exe) copy that file on ur bootable floppy if u don't wanna spend lot of time copying files from installation media to temp folders, it comes with windows 98, search for it.
3. now locate i386 directory for ur WinXP setup and run winnt.exe from it.
