This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Formatting the drive will cause you to lose all existing data. It's unclear whether or not this is acceptable to you. If it is, the answers you've received are correct: boot from your Windows 7 DVD and follow the wizard's instructions to format (and repartition) your drive, then install Windows. – Cody Gray Jan 23 '11 at 4:52

If you have the Windows 7 disc then just boot from that and follow the instructions, you shouldn't need to wipe/format the drive yourself.

oh ok i will try that now thanks – Kevin Jan 23 '11 at 3:14

When you are installing Windows, the installer will wipe and possibly re-format the drive, erasing everything that was there.

Insert your Windows 7 DVD in the DVD-Rom, and restart the computer , it will boot up by itself. Follow the instructions and from there you can format the drive from a graphical menu . If the Dvd didn't boot up tell us.

Formating the drive will wipe everything , so have you done it ? – binarylife Jan 23 '11 at 3:15
no but if i do will i be able to reinstall the os? – Kevin Jan 23 '11 at 3:16
No, because format clears everything on the drive including the OS , if you want to reinstall , do not format – binarylife Jan 23 '11 at 3:18… – binarylife Jan 23 '11 at 3:21
