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:
Put the installation CD of XP or Windows 2000 into the CD drive assembly and start the computer again. It should soon say "Press a key to start from CD".
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".
