I want to uninstall Windows XP Home from a computer that I have. I can not
get it to uninstall or format the drive. It does not show up in Add/Remove
Programs in Control Panel. Help!
As a general rule, you can't uninstall an operating system. You have
to reformat the drive and install another operating system cleanly.
There's an exception to that, however. If you did an upgrade from
Windows 98 or Me, and took the option to save the previous operating
system and also did not convert your drive to NTFS, then you can find
an entry in Add/Remove Programs. Clicking on that will uninstall
Windows XP and revert to the previous operating system.
If there's no entry in Add/Remove Programs, then one or more of those
conditions wasn't met, and your only choice is to reformat and install
whatever operating system you want cleanly.
You can't format the Windows drive from within Windows, since that
would leave Windows without a leg to stand on.
Just boot from the Windows XP CD (change the BIOS boot order if
necessary to accomplish this) and follow the prompts for a clean
installation (delete the existing partition by pressing "D" when
prompted, then create a new one).
