set up unable to format the partition. the disk may be damaged
make sure the drive is switched on and properly connected to your computer. if the disk is a scsi disk make sure your scsi devices are properly terminated.
consul your computer manual or scsi adapter documentation for mor information.
you must select a different partition for windows xp.
and when i try to repair it it says
setup has determined that drive c: is corrupted and cannot be repaired. setup cannot continue.

Answer #1
Grab Hiren’s BootCD and burn it. Then boot from it and use the partitioning tools there to try and format your HDD. After that try installing the OS on it. Here are links to Hiren’s BootCD:

Answer #5
don’t format, just delete the partition
then recreate it during the XP setup
with partition magic, if the disk has errors it will tell you that and offer to fix them – hopefully that don’t work try the HDD utility for you brand disk and do a low level format
