GRUB setup problems

I think this would belong here, since GRUB is software, but if it doesn't, please move this...

I'm trying to install GRUB on a SATA hard drive. I've already partitioned the drive, formatted it to ext3, and installed Debian 3.1r0a/kernel- on it. Now I'm trying to install GRUB on it so I can boot from it. I've set /dev/sda1 (the / partition) bootable. I've edited my /boot/grub/ and /boot/grub/menu.lst to boot from /dev/sda. I've set hd0 to /dev/sda. When I try to configure the MBR, this happens:
grub>root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd1)"... 16 sectors are embedded
Segmentation fault
If I restart the computer and boot from the new drive, I get a black screen with the blinking _ at the top, then it moves down two or three lines and stays there. What should I do now?

Just a guess, but your filesystem type (ext3) doesn't tally with what grub has found (ext2fs). That could be the cause of the segmentation fault.
Also you you say have the device set as /dev/sda1 which is a scsi drive device. I would have thought your SATA was IDE and should be /dev/hda1. This is what grub is looking for!

hda1 is already an IDE hard drive... Debian 3.1 doesn't come with support for SATA drives, so I had to rebuild a kernel for them. Now I'm moving my Debian install from a 10GB to the 250GB hard drive. The kernel detects the SATA drive and sets it as sda, for some reason. "cfdisk /dev/sda" says that my partitions are ext3 (except for the swap partition), and I set them up as ext3 using commands like "mke2fs -j /dev/sda1", so I'm not sure why GRUB is seeing them as ext2. Is there any way I can tell GRUB to assume they are ext3 filesystems?
