If you've upgraded to XP from
Windows Me or Windows 98, go to the Add/Remove Programs Control Panel applet
and click Uninstall Windows XP.
If you want, you can also uninstall
XP from the command prompt by performing the following steps:
* Start the computer in Safe Mode with Command Prompt support (press F8
during start up).
* Type osuninst.exe and press Enter.
* Follow the onscreen instructions.
If XP was installed as a dual-boot
system along with Win98 or W2K then you can simply format the partition on
which it is installed. That is one of the reasons I always recommend to install
separate operating systems on separate partitions!
Note: Windows XP Professional
provides an uninstall tool when upgrading from Windows 98 on a drive formatted
as FAT or FAT32. Therefore, when upgrading this type of drive, you will not
have the option to upgrade to NTFS, as this would negate the uninstall option.
However, you can convert the drive to NTFS after installation if you choose.
