Hi kyrios I would suggest you get a Windows98SE 3.5" floppy boot disk and use that to get you to the installer from the CD.

Also, try going into "setup" on boot................ you may have an option............careful now, that is sometimes called "search for bootable media"............. usually the last one

Obviously, these are genuine XP CDs and in good condition?.........like clean?



EDIT: They are from the SAME CD set?........that used to be a real pig if you had several mixed up?
