Step 3

Right-click the drive you wish to format, and click “Format.”

Step 4

Click the “Yes” button if prompted.

Step 5

Type a volume label. This is just a display name, so feel free to select whatever descriptive name works for you.

Step 6

Uncheck the “Perform a quick format” box. A “quick format” doesn’t actually wipe any data; it simply flags the volume as “free” so it can be overwritten.

Step 7

Click “OK” twice. The formatting process can take anywhere between a few minutes and a few hours, depending on drive size.

Step 1

Click Start, “Control Panel” and then “System and Maintenance.”

Step 2

Click “Backup and Restore.”

Step 3

Click “Create a system repair disc” on the left.

Step 4

Insert a writable CD into your CD/DVD drive and click “Create disc.”

Step 5

Click “Close” and “OK.”

Step 6

Reboot your computer, and tap the appropriate key to bring up your boot menu. F10 and F12 are common. Refer to your computer’s user manual if you’re unsure which key should be used.

Step 7

Select your CD/DVD drive as your boot device, and press “Enter.”

Step 8

Press any key to boot to the disc when prompted.

Step 9

Click the “Next” button. After a few minutes, the System Recovery Options dialog box will appear.

Step 10

Click the radio button next to “Use recovery tools that can help fix problems starting Windows. Select an operating system to repair.”

Step 11

Select your Windows installation. In most cases, there’ll only be one operating system listed. Disregard the reported drive letter, as it is often incorrect. Use the partition size as your reference instead (in most cases, your Windows partition encompasses nearly your entire disk).

Step 12

Click “Next.”

Step 13

Click “Command Prompt.”

Step 14

Type the following command (without quotation marks here and throughout):
“vol C:”

Step 15

Press “Enter.” Note the volume label, which appears after “Volume in drive K is.”

Step 16

Type the following command:
“Format c: /fs:NTFS”

Step 17

Press “Enter.”

Step 18

Type the volume label you obtained in Step 15 and press “Enter.”

Type “Y” and then press “Enter” when prompted. The process should take an hour or more to complete, depending on disk size.

Step 20

Type a new volume label for the drive, and press “Enter.”

Step 21

Remove the system repair disc, and shut down your computer.
