How to Remove a Dual Boot GRLDR


The cryptically named GRLDR is the folder from which the Grand Unified Bootloader (known as GRUB) boots DOS. If you no longer need to run DOS on your computer, you can free space and processing power by deleting the GRLDR folder, and with it the GRUB boot system. This will remove the dual boot setup and allow your PC to run only Windows. Your computer will no longer ask what operating system you wish to boot every time you turn it on.

Things You'll Need

  • Windows installation CD
  • Turn off your computer.

  • Insert your Windows installation CD into your CD drive.

  • Turn your computer back on. Your machine will auto-detect the CD and boot from there.

  • Type "r" to open the Recovery Console when prompted.

  • When you see a cursor flashing, type "fixmbr" (no quotes) and press "Enter." This will remove your dual boot settings and delete the GRLDR folder.

  • Type "exit" (no quotes) and press "Enter."

  • Restart your machine.

Tips & Warnings

  • Be sure to back up your files before proceeding. Though they shouldn't be deleted by this procedure, you can never be too safe when changing operating system configurations.
