Question Help needed with bootloader configuration !
I have installed Fedora 8 in my external harddrive in my laptop( toshiba satellite 1135-S125). During initial installation i installed the bootloader in the MBR of the external harddisk instead of the internal harddisk. the problem is that i donot always turn on the external harddrive;therefore, the settings in my BIOS to boot from external harddrive is void when i boot my laptop without the harddisk on.

So most of the times i have to go to my BIOS settings to change the boot order again. Installing the bootloader in MBR of internal harddisk must solve this problem, my guess.

How can i remove the bootloader installed in the MBR of my external harddisk and install it in the MBR of my internal harddrive without re-installing the OS. I have windows xp installed in my internal harddrive and both linux and windows work fine. Please do advice on how to change the bootloader configuration.
