How to Get Rid of GRUB on a Slave HD

The GNU Grand Unified Bootloader, or GRUB, is a program that enables a user to select an operating system to boot from on a multiboot operating system. If you install certain distributions of Linux to a slave drive containing Windows, the Windows bootloader will be replaced with GRUB. You can reinstall the Windows bootloader to the slave HD through the Windows 7 DVD to get rid of GRUB.

Things You'll Need

• Windows 7 DVD

Instructions

1. Insert the Windows 7 DVD into the disc drive. Restart the computer to boot to the DVD drive.

2. Follow the onscreen instructions to choose your language and regional options and select the correct operating system on the slave hard drive.

3. Click "Repair Your Computer." Click "Command Prompt." Input "diskpart" and press "Enter" to run DiskPart."

4. Type "list disk." Press "Enter" to see the list of hard drives installed to the computer. Input "select disk <#>," replacing "<#>" with the number assigned to the slave HD. Use the storage space on the drives as a guide to determine which disk to select.

5. Input "detail disk" and press "Enter" to see the drive letters assigned to the system volume on the disk. Input "bootrec.exe fixmbr <disk>:" into the command prompt. Replace "<disk>" with the letter assigned to the system volume on the drive.

6. Press "Enter" to get rid of GRUB on the slave HD. Close Command Prompt when the process is complete, then click "Shut Down" or "Restart" to exit from the Windows 7 DVD.

Tips & Warnings

• If you don't have the Windows 7 DVD, press "F8" when booting the computer to go to Windows Advanced Boot Options. Select "Repair Your Computer," then press "Enter."
