Formatting: Format drive C in XP or Windows 2000 and erase all data
Von Markus Schraudolph am 06.01.2006
Formatting a hard drive is done with a few mouse clicks using the Disk Managment of Windows XP or Windows 2000
The option "format" however is grey for the drive C: or wherever Windows itself is located. This option is deactivated because the system does not allow to wipe itself off the drive.
If you want to format this drive nevertheless, use this way:
If not, you have to change the boot sequence in the computer´s BIOS. Another option is to use a special function key which shows a boot menu where you can chose the CD drive, if provided. The most common keys for this are [F12] and [Esc].
With the first screen of the setup program select "R" to enable the repair mode. The next screen allows you to select a Windows installation for repair and asks for its admin password after that.
Now you get a command line interface. Enter "map" here and you will get an overview of all partitions and their corresponding drive letter.
If you made sure which drive you want to format, type the command "format", followed by the drive letter like
The system will then format the drive with the same file system type that the drive already has. Using the parameter "/fs:" you can choose a certain file system. If for example you want to format drive C: with NTFS you enter
format C: /fs:ntfs
To leave the console, type "exit".
if your computer come with the cd to reinstall windows xp or vista ur
product key should be on your computer tower or at the bottom of your
laptop if you do find it write it down and put it away for safety.

didn't work. I typed in "format c:" (tried it twice now), and nothing
was formatted. the installation just went over the old xp-version and
left the whole rest of the harddrive untouched. god, I miss windows

When I try to format my HD in the repair console it starts off fine
but when I type in "format c:" it says "The parameter is not valid.
Try /? fior help." Allthough the drive I want to format IS c:. Even
the Console itself says that after I type "map" or "format /?"
Maybe its beacuse im installing XP on a german Laptop (with a german
keyboard), OR the error might be caused because there is Windows 2000
Can anyone help me, please?

I get to the point on the Recovery Console where you have to type in
the administrator password and thats where I stop.
What exactly is the administrator password? The password you use to
log on to XP or what?
As far as I know I am the computer administrator and entering my
log-in password doesn't work. Any tips would be much obliged?
I am rather annoyed as I am only about 2 steps away from formatting
the c drive.
