I am attempting a stage3 install. I did almost everything exactly the way the handbook said to.
The only thing I didn't do was to create a /boot partition. Or install a bootloader. I tried installing to /dev/hda9 where / is. But,it kept giving me errors. So, I didnt bother. I am using SUSE's grub bootloader to boot all the rest of my OS's.
I used a genkernel, and put the information that the handbook said to put in to the Gentoo bootloader, and I put that in my SUSE menu.lst.
Now when I try to boot Gentoo, I get Grub error 15, file not found.
The only other thing I did different was in the title I put Gentoo, instead of Gentoo+the kernel name. But I don't think that should matter.
