The story starts like this: I wanted to install ros in a hd where I had X/K/Ubuntu or "put your favorite distro name here", and I had to install Lilo or Grub, I deleted all the partitions, I've made a new one for ReactOS and I "suppose" the disk is clean, now that I have installed ReactOS I can't start freeldr… :’( T_T
In this tutorial we'll show you the 10 steps to recover and reinstall your Master Boot Record (MBR) in a disk that has already had GRUB or Lilo installed using Super Grub Disk, to be able to start later freeldr without any problem…
I don't know if it's a defect, a slip, a bug or incapacity of ReactOS but the point is that after having installed GRUB in a hd ReactOS can't replace the Grub's MBR. In this tutorial we'll learn to reinstall (so to speak) the Master Boot Record (MBR), to start FreeLoader without problems.

In some motherboards to start the PC from a CD/DVD you hit F8 or F11 to enter the menu where you choose where to boot from.
Anyway, you can also do it changing the boot sequence in the BIOS.
To enter the BIOS:
When you turn your computer on, hit DEL, other alternatives are Insert or F1, F2, F10.
Try to see where ‘Boot Sequence’ or ‘First Boot Device’ is
Download Super Grub Disk from here. Then burn it into a CD/DVD (rewritable preferably). You can do it with InfraRecorder.
Alright, let's work.
We boot the computer from CD/DVD, then we choose the options hitting ENTER.
1. “Super Grub Disk”
2. “Choose Language & Help”
Help is shown in a clear and simple language.
3. “English Super Grub Disk”
5. “Fix Boot of Windows” [“Fix Windows MBR”]
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.... xD
After this, we'll have the MBR ready to proceed with the installation of ReactOS without issues.
PS: Super Grub Disk is useful to recover GRUB after having installed Windows too.
