I went through the entire install 4 times now trying different things. When I reboot, I never even see GRUB, it just automatically reboots.

Dual Celeron 366 (I loaded the celeron kernel option, not the P3)
512MB RAM
Matrox G400

SCSI system:
  1. 18GB hard drive
    1. sda1 (5GB) - WinXP NTFS already installed (4 trial installs of Gentoo and never killed my XP partition, woohoo :D )
    2. sda5 (10GB) - NTFS Windows files partition
    3. sda6 (100MB) - ext2 /boot
    4. sda7 (256MB) - swap
    5. sda8 (rest) - ext2 /
  2. Plextor 40Max
  3. Plextor 8x20
  4. Pioneer 6x DVD
40GB IDE NTFS drive of files for WinXP

Now I set up grub as following
Code:

grub> root (hd1,5)  /* b/c hd0 is my IDE drive, tested with TABs */
grub> setup (hd1)
grub> quit


My menu.lst:
Code:

default 0
timeout 30
splashimage=(hd1,5)/boot/grub/splash.xpm.gz

title=Gentoo Linux
root (hd1,5)
kernel /boot/bzImage root=/dev/sda8

title=Windows XP Pro
root (hd1,0)
rootnoverify(hd1,0)
makeactive
chainloader +1


The result is the same every time, when I reboot, my computer will get to the point where it should run GRUB, but it will just reboot instead.

Any ideas?

PS... need more info, say so, I'll give what I can to get this to work.

As far as I can see, you overlooked something simple. Grub maps disks differently then linux. Example, you say (hd1), and in linux that means /dev/hdb (or the scsi equivalent for second physical driver). Grub starts counting at (hd0). And you only have one physcial drive correct?

Another possibility is that what you think is hd0 might not be so as far as Grub is concerned. The problem is that when you have a mix of IDE and SCSI drives you cannot be sure which drive is what. The order is determined by the BIOS. I had to use the grub 'find' command to locate the correct hd number. Do a find on your bzImage and Grub will tell you which hd it found it on. This is your boot partition.

I have 2 hard drives, the IDE and SCSI. I'm installing on the SCSI.
I did the find, no luck, told me the same drive as I thought... (hd1,5)

Could it be a kernel option I put? I don't think that would be an issue as GRUB doesn't load any of the kernel until I tell it to, correct?

You still have to install Grub on hd0, your BIOS drops boots off your primary master. I think you would run setup (hd0) and leave everything else the same, but I'm no grub expert.
