format and reinstall

wats the correct way to format and reinstall win xp 64bits

every time i install ( without formatting)
when i install driver my pc will prompt i already have the driver

so i need to format and reinstall a real fresh one

how to do this

thanks

 

To format and re-install:

1. Configure your BIOS to boot from CD before hard drive
- Enter BIOS. This takes a specific keystroke IMMEDIATELY after the power is turned on. The first screen will say which. (usually F1, F10, delete..)
- Look for Boot Order, Sequence, Priority - or something similar (different for each BIOS), and set CD ROM to the top of the list.
2. Insert the XP installation disc
3. Restart the computer
4. When prompted, press any key to boot from CD

From there, it is as simple as following the prompts to completely format and re-install your operating system.

 

i can boot from cd

the prob is the reinstallation is not formatting the drive
and always say i have all the drivers and so on
which my the reinstallation nothing
