Dell Laptop Corruption Files

Why is it that every time I re install Win XP I can never seem to get the whole partion of a disk to install XP without a disk error.I always get a message saying some files corrupted or not found.

erase and reformate the HDD, and try again and clean the XP disc.

Hi and Welcome!

this could also be a sign for bad hardware like HDD or RAM.
If the diagnostics partition is still functional, then run the Diagnostic Utility. Or download from Dell support website and either create a bootable CD or USB stick.
