How to Format Windows 8

Last Updated: August 2, 2021

While you can format any drives connected to your computer in Windows 8, you can't format the drive partition that actually contains the Windows 8 files. To do this, you'll need to either start an operating system installation so that the drive is formatted, or use a drive erasing program like DBAN.

7
Save your changes and exit the BIOS. Your computer will reboot.
8
Press any key when prompted to start the Windows 8 installation. The setup program may take a few minutes to load.

Wiping and Formatting the Drive

1
Download DBAN. DBAN (Darik's Boot and Nuke) is a free hard driver eraser that will completely wipe the entire hard drive containing Windows 8. The hard drive will be empty and need to be either initialized by another operating system for storage or have an operating system installed on it.
- This will delete everything on the drive, so make sure anything you need to save has been properly backed up. You will not be able to use data recovery software on the drive afterwards to retrieve anything you forgot.
- If Windows 8 is your only operating system, you won't be able to use the computer until you install a new operating system or reinstall Windows 8.
- Do not use this method if you have a solid state drive (SSD). If you are formatting an SSD, the best way is to simply reinstall your operating system on it. Do not use traditional data-wiping methods when trying to completely format an SSD. These can drastically reduce the lifespan and may not actually remove any data.
2
Burn the DBAN image to a blank DVD. DBAN is downloaded in ISO format, which is a disc image file. This allows you to burn it to a disc so that you can boot your computer from it. You can use a free burning tool like ImgBurn to burn the ISO to a disc. Click here for detailed instructions.
3
Reboot your computer. You will need to open your BIO settings to change the boot order.
4
Press your BIOS setup key before Windows loads. This is typically F2, F10, F11, or Del. Your computer will display the proper key before Windows loads.
- If your computer is booting too fast to enter the BIOS, click here for instructions on forcing the Advanced Startup menu to appear.
5
Open the BOOT menu in your BIOS. This will allow you to change the order of devices that your computer tries to boot from.
6
Set your DVD drive as the primary drive. This will make your computer try to boot from the DVD first, loading DBAN.
7
Save your changes and exit the BIOS. Your computer will reboot and DBAN will start.
8
Press .↵ Enter to start DBAN. DBAN will take a few moments to load.
9
Use the arrow keys and then press .Space to select the drive you want to erase. If you have multiple drives, be absolutely sure that you have the right drive selected. You can use the drive sizes to help determine which drive is which.
10
Set your wipe settings. There are several settings you can change, but most users can simply leave everything at default.
- Press P to open the "PRNG" menu. This stands for Pseudo Random Number Generator, which is the algorithm used to wipe the drive. There are two different algorithms to choose from.
- Press M to open the "METHODS" menu. These are the number of passes that DBAN will make over the drive. More passes means a more secure erase, but also significantly increases the time it will take. If you're just wiping the drive to reinstall, you can choose one of the lighter-security methods. If you're wiping to erase sensitive data before recycling the drive, select one of the more secure methods.
- Press R to set the number of "ROUNDS". This is the number of times the wipe process will be run. More rounds means a more secure wipe.
11
Press .F10 to start wiping the drive. DBAN will use the methods you picked to begin overwriting all of the sectors on your drive. You will be able to see the time remaining in the upper-right corner.
12
Use or dispose of your newly-wiped hard drive. Now that your hard drive is wiped, you can move on to doing whatever it is you want to do with it.
- If you want to reinstall Windows 8 or install another operating system on it, click here. This will format the drive and install the operating system. If you wiped your only hard drive with an operating system installed, you'll need to install an operating system before you can use it again.
- If you want to use the drive as storage for another operating system, click here for instructions on formatting it for use as storage.
