GRUB bootsystem

[Sorcim]

Hi,
I have a problem with my GRUB loading system.
I had installed SuSE Linux 9.0 before installing RedHat Linux today.
Well, I installed RedHat by inderting the cd1 and i let the setup formating and deleting my old SuSE Linux. I have chosen to install the Grub on my Linux Drive (I have another drive with WinXP). But if I start my PC now, it displays GRUB... on a black screen and stops working...
I think SuSE had installed the Grub-System, too. Is it possible to disable the Grub System or reinstall it in RedHat and how to do this?
Thx Sorcim

P.S.: sorry for my bad Englisch

Take a look at this tutorial by nerderello. Also, look at my notes in the following threads:

I'm pretty sure that you have to install GRUB to the MBR, or else it will not work.

mjmam, you are right that GRUB must be installed to the MBR to boot. From Sorcim's message, I believe that this was done by SuSE, but now it just needs to be redirected to the right kernel and init. One of the threads I mentioned before attempts to explain this. It's the difference between getting grub> and GRUB_ as the prompt. The details of loading the bootloader is pretty interesting, being that it is done in 3 distinct stages even before the operating system is selected. Understanding the loading sequence is key to efficiently correcting boot problems.
