Installed GRUB on MBR or First Sector of boot partition
I want to understand the concept of this:
I installed windows on the HD.
I want to install FC3, I partitioned the hard disk , the (/boot) is hda2, and the roo (/) hda4,and the rest.
If I want to install bootloader (GRUB) , I will get two options
1- First sector of the drive (MBR).
2- Fisr Sector of the boot partition.
I did two tests:
1- Fisr sector of the drive (MBR) :
There was no problem (I could boot windows and linux FC3 on some PC and Mandrake on the other)
2- First sector of root partition
There was problem, althought I tried to activate /boot (in my case hda2 not root) by using system commander utility ,it did not work, then I tried to activate root (/) (in my case hda4, not /boot) by using system commander utility, it did not work either
With the second option I have read (I have not tried it yet) , that I have to modify the bootloader for windows NT (I read many article on net) to point to the bootloader (LILO, GRUB) for linux (i.e to point to the "/boot" directory , which is in my case "hd0,1").
Then why should I activate (make it active) the partition that contains the "/boot" directory, if I am going to modify the NT bootloader ?
My understanding (Correct me if I am wrong), I have to modify the bootloader for NT; to point to the bootloader for linux (LILO, GRUB), and I should make the NT bootloader active (not Linux bootloader)
