How to erase my hard drive and start over

Updated: 04/12/2021 by Computer Hope

Computer hard drive

Most computers have a system restore disc or built-in restore process on the hard drive to reset the computer to the original or default settings (factory reset). Resetting, formatting, or restoring, a computer helps eliminate issues with computer software, including corrupt program files and virus infections. Instructions on how to restore your computer back to the original software are provided below.

Warning

Restoring your computer erases all the information on the hard drive and makes it like new. Once the steps below are completed, you cannot restore any lost data. Back up any files you do not want to lose before proceeding with the restore process.

Windows 7 and Vista

To restore a Windows 7 or Vista computer, you must have a set of restore discs for the computer or an original Windows 7 or Vista installation disc. If you do not have a set of restore discs, contact the computer manufacturer to order a new set or restore discs.

Note

Before following the steps below, make sure the computer is set to boot from the CD-ROM drive.

Earlier versions of Windows and DOS

Follow these instructions to erase and reinstall MS-DOS 5.0+, Windows 3.x, 95, 98, ME, or NT 4.0.

Formatting the drive

  1. Place the bootable diskette or disc inside the computer and reboot to get to the DOS prompt. In some cases, you may need to boot the computer with CD-ROM support or press a key to boot from the disk.
  2. At the MS-DOS prompt type, format c: /s

Note

If the "format c: /s" command does not work, you may need to download the format.com file to your boot disk.

  1. The computer asks you "Are you sure you want to erase everything on drive c:"
  2. If you are ok with doing this, press "Y" for yes and press Enter.
  3. After doing this, the computer begins the formatting process. While the computer is formatting, make sure no errors are encountered.
  • I'm getting bad sectors, clusters, or missing allocations.
  1. Once the format process is completed successfully, at the MS-DOS prompt, type "fdisk /mbr" and press Enter. After entering this command, it should return you to the MS-DOS prompt with no message. This step is not required, but recommended.
  • Do you have additional information on fdisk /mbr?
  1. Once back at the MS-DOS prompt, reboot the computer with the boot disk still inserted and follow the steps below to reinstall Windows on the hard drive.

Windows NT 4.0

Windows NT can be installed in different ways. We recommend Windows NT be installed using the steps below as we feel that these steps by far are the easiest way to install Windows NT 4.0.

First, we recommend all users wanting to install Windows NT use the /b switch, which allows the users to not need to create the diskettes. We do, however, recommend the user create the emergency recover diskettes if they have not already been created after the installation of Windows NT.

Finally, before the installation of Windows NT, we recommend you run smartdrv, which helps the installation of Windows NT run a lot faster.

  1. Place the CD into the computer.
  2. Type X: (where x is the CD-ROM drive, often this is D:).
  3. Once at the appropriate drive, type cd winnt and press Enter to get into the Windows 95 directory.
  4. Once at X:\WINNT> type winnt /b.
  5. Follow the on-screen instructions to complete the installation.

Windows 95 with a backup CD

  1. Place the CD into the computer.
  2. Type X: (where x is the CD-ROM drive, often this is D:).
  3. Once at the appropriate drive, type cd win95 and press Enter to get into the Windows 95 directory.
  4. Once at X:\WIN95> type setup to begin the installation.
  5. Follow the on-screen instructions to complete the installation.

If you are encountering issues during the setup process, you can add additional switches to the setup command line. These switches are on our Windows 95 setup switches page.
