Do i need to change my harddisk?

UBUNTU is a version Linux its formatting is different than Windows. If you are trying to setup a dual boot system (ability to boot linux or windows) my suggestion is that you partition the HDD install windows on one partition and then windows on the other. or just use seperate HDD. >>>>
If you just want windows installed low level format the HDD and windows should be able to recognize the drive. >>>>
you can low level format using POWERMAX - download and burn to cd >>> powermax4.09.iso go to http://digilander.libero.it/YorkOne/powermax/
>>>> the cd will be bootable just pop it in and reset

Good luck dont forget to RATE :]

Hello,

It sounds like UBUNTU formated your hard drive where xp does not reconized the drive. When you go into BIOS setting, do you see your hard listed? If so, you should be able to put a clean install of XP to the drive. When you start the install, you must select REFORMAT drive and install XP. If this still fails, you may need to fdisk your drive first using DOS command and reinstall XP. Let us know if you incounter any more problems after doing this. Good Luck.
