Ok, I had Windows XP installed on my fathers computer using 2 partitions. 98 on c: and xp on d:. Then we started getting errors on xp (cannot remember exactly which one) but I do recall it said something about dumpfiles. XP would crash every minute or so after this. But booting into 98 worked perfectly. After deleting both partitions and formatting I can no long install XP (I think this also was a dumpfile error) It starts the installation then gives an error. But yet again 98 installed flawless and works perfectly. Can anyone explain why this would happen? How can I fix it? Only thing I can think of is something to do with cache. Do I need to clear it? if so... how? Thanks for your time.
