GRUB loader

I have a dual boot system Win98 and RedHat 9 with GRUB boot loader. I have 2 hard drives 1 windows and 1 Linux, if I removed 1 of the drives would the GRUB know what to do or would I not be able to boot up?

it depends on which driver you put grub.

GRUB is on windows drive. Master drive, Linux is on Slave drive.

No, you will not be able to boot.

GRUB is installed in the MBR of the primary HDD, but the configuration files are in /boot/grub which is located on the second HDD.

If you want to take away linux and only want to boot windows, you don't need GRUB anymore.

The reason I ask is this...what if something were to go wrong with my Linux syetem (eg..by experimenting I screw it all up)...and that disk becomes unusable , will I lose my access to the Windows info at that time?

You can always make a windows boot disk just in case.

ur windows should be safe... but you may need to fix the MBR of the first drive to boot into windoz... it is NOT something difficult... so dun have to worry... but it is good to always prepare a window bootdisk with fdisk on it

Is MBr (Master Boot Record) and if I had to fix it, how would I do that? I figure I should ask BEFORE it goes bad, because if it were to go bad I wouldn't be able to access internet for advice to get help.

MBR = Master Boot Record

As I mentioned before, since you are using Windows98, you will need to make a windows Boot Disk.
If something goes wrong with GRUB. You can use the windows boot disk in order to boot windows into DOS and install the windows bootloader by typing: fdisk /mbr

However, you can also use a Linux Boot Disk in order to boot Linux.
In Linux, you can always re-install GRUB back into the MBR.
