This tutorial intends to show you the steps to repair the master boot record using Super Grub Disk to be able to start FreeLoader. Super Grub Disk is useful to recover GRUB after having installed Windows too.

The Problem

The story starts like this: I wanted to install ReactOS on a hard drive where I had X/K/Ubuntu or your-favorite-distribution, and I had to install LILO or GRUB, I deleted all the partitions, I have made a new one for ReactOS and I suppose the disk is clean, now that I have installed ReactOS I can't start FreeLoader.

Due to #2733, ReactOS cannot boot with a boot loader previously installed on the disk.

The Solution

You will first need to ensure your computer is set to boot from the CD drive before the hard drive. This is done by changing the boot sequence in the BIOS settings (refer to your computer manual for information on how to access the BIOS settings). In some motherboards, to start the computer from a CD or DVD, you hit F8 or F11 to enter the menu where you choose where to boot from.

Download Super Grub Disk and burn it to a CD or DVD (rewritable preferably) using any software of your choice. Start the computer with the CD in the drive and boot from it. Choose the following items to repair the master boot record:

1. “Super Grub Disk”

2. “Choose Language & Help”

Help is shown in a clear and simple language.

3. “English Super Grub Disk”

http://reactos.files.wordpress.com/2009/05/03-sgd.png

4. “Windows”

http://reactos.files.wordpress.com/2009/05/04-sgd.png

5. “Fix Boot of Windows” (“Fix Windows MBR”)

http://reactos.files.wordpress.com/2009/05/05-sgd.png

6. “Syslinux”

7. Choose your hard disk: (you'll recognize it by the size) 

1 hda sda (hd0) hd0 74GB
2 hdb sdb (hd1) hd1 8GB

Where options 1 and 2 are your physical hard disks (not the partitions). If you have more HDs they will appear here.

8. After choosing the hard drive, SGD will show you:

“SGD has succeeded”

9. “Reboot P.C.”

10. Stop reading this tutorial and hurry up to remove the CD/DVD from the tray before the computer boots again from it.

After this, the master boot record will be ready to proceed with the installation of ReactOS without issues.
