Also I found the following at http://www.geocities.com/epark/linux/grub-w2k-HOWTO.html "# When I select Linux from the boot menu, I get a frozen "GRUB" (or an "L" in the case of LILO) # Make sure you created the linux.bin file correctly with the dd command. If you think you ran the command correctly, the problem may be that your /boot partition is beyond cylinder 1024 and your BIOS can't reach it. At system startup, the Windows boot loader lists the choices from boot.ini. When you select Linux, the boot loader then loads the 512-byte linux.bin file, and then BIOS tries to access the /boot partition to run GRUB. Some BIOS implementations can only address the first 1024 cylinders of a hard drive, which corresponds to ~8.5 GB. How do you fix this? Create your /boot partition before cylinder 1024; i.e. before ~8.5 GB." Does this scenario sound familiar? Did you have to create a linux.bin file or a BOOTSECT.LNX file on your Windows box? If it, it sounds like a kernel update may require that you rebuild either applicable file in order for it to work again. Having said that you are getting the grub prompt so it would appear that the Windows boot loader is pointing to the right place for your grub boot loader. Which brings us back to a likely grub.conf configuration problem. But before suggesting how to trouble shoot that I'd like to make sure that what I suspect is happening (as per previous posting) is indeed happening. Jacques B.
