I have that problem whenever I install Etch: the installer says its installing Etch but it doesn't. I end up rebooting the installer in rescue mode and doing it from the menus again. > I also have Ubuntu, so I installed grub manually by chrooting to the Debian > partition.The two systems are installed on separate disks. > Debian is installed on a SATA disk.I didn't have a Sata controller on the > motherboard so I had used a PCI SATA card.My bios can't boot on that disk > (not sure why). I don't know if your bios can boot a kernel on a drive from which it can't boot, even if it can load grub. You may need to put a 64 MB partition on the Ubuntu disk and use that for Debian's /boot. > My only option to boot Debian is trough Ubuntu's grub.

Is the "Could not mount" error coming from grub (e.g. couldn't find the kernel) or from the kernel (e.g. couldn't find the root partition). > The two menu.lst entries: > > title Debian GNU/Linux, kernel 2.6.24-1-686 > root (hd0,1) > kernel /boot/vmlinuz-2.6.24-1-686 > root=UUID=5dd1a349-c311-40ca-82f4-a7a39ca134a3 ro > initrd /boot/initrd.img-2.6.24-1-686 > > title Debian GNU/Linux, kernel 2.6.24-1-686 (single-user mode) > root (hd0,1) > kernel /boot/vmlinuz-2.6.24-1-686 > root=UUID=5dd1a349-c311-40ca-82f4-a7a39ca134a3 ro single > initrd /boot/initrd.img-2.6.24-1-686 > > I'd go to the grub command promt and try entering things manually, using grub's tab-completion to ensure that devices are correct.

Booting issues are where a serial console (or logging the output directly to a printer on lp0) is very helpful. You can see the serial-console HOWTO for how to set that up, as well as the grub manual for how to have grub talk to a serial console.
