I have been experimenting with Linux for a few months now. Recently, I built a computer intended for rendering 3-D frames, but I decided to also install Linux on it. Before Linux, I had a single 120GB hard disk which allowed me to boot both Windows x64 and Windows XP ((SATA)). I also got another 120GB hard disk ((IDE)), to install Linux on. I had SuSE 9.1 installed and was able to multi-boot all three OS's using GRUB. I upgraded to SuSE 9.2 64-Bit, as I have a Athlon 64 CPU. It would not allow me to upgrade, so I just reinstalled Linux completely. Now, it will not let me multi-boot like I used to. I would very much like to be able to multi-boot again, as changing the boot order every time I boot the system is a hassle. My configurations are below:

System:
AMD Athlon 64 3400+ ((ClawHammer))
MSI K8N Neo Platinum
ATI Radeon 9600XT ((256MB))
Corsair ValueSelect RAM ((1 GB))
Hitatchi SATA 120GB
Western Digital IDE 120GB
SuSE 9.2 64-Bit

Thank you,

Do you know if the options in these files are different from the old (working) setup? Did you make any modifications to the system before installing suse 9.2?
Also, what happens when you boot this setup? Do you get any error? Do you get an empty menu? Do you get a broken menu entry?

what system is booting? windows? did u again activate the master boot record?
i have suse 9.0 but probably its more or less the same with 9.3:
YAST:->System:->Configuration of bootloader

Stefan: I believe these files are at least slightly different from the working ones. I did not make any mods to the system before installing. When I boot this setup, SuSE boots fine, but Windows says "OS not found".

J-ray: The system is booting off the MBR of my Linux IDE hard disk.

I guess you have already checked this, but make sure your Windows partition is specified correctly, and your device.map is good. You could also try a grub floppy, to see if there is something wrong with your installation. Try using the grub prompt or edit mode to get the right command sequence, there is no need to reboot and edit menu.lst.
