Update.

After a little bit of surfing, I tried the command grub-install --recheck /dev/sda
That changed the device map file so that the /dev/sda drive mapped to hd2

The full /boot/grub/device.map listing is now
(fd0)   /dev/fd0
(hd0)  /dev/hde
(hd1)  /dev/hdh
(hd2)  /dev/sda

I edited the grub.conf file so that the splash image and root lines reference (hd2,5), then re-ran grub-install /dev/sda.  Still no joy.  On boot up, the screen stays blank for a while, then every 10 seconds or so, it adds another " GRUB" text element to the screen.  No sign of any boot-up activity.

Try running grub, then at the grub command line:

[gentoo-user] Re: Grub problems

[Jeff Cranmer]

I am trying to bring up a new Linux unit (my old desktop died on Thursday).
My hardware is an ASUS M2NPV-VM motherboard, running an Athlon X2 3800+ Dual core processor.

I have a serial ATA 250GB hard drive which I am attempting to install my OS into.  The hard drive maps in the bios to SATA4, and maps within Linux to /dev/sda.  

I also have two other parallel IDE dard drives, connected via a raid controller (though not configured for RAID) to Drive numbers 0 and 3 on the RAID controller.  These drives map to hde and hdh respectively, with a DVD writer mapping to both /dev/hda and /dev/dvdrw.

The bios is configured to boot first from the DVD (primary IDE master) then from the 250GB SATA hard drive.

swapspace is on /dev/sda2,  /boot is on /dev/sda1, and root is on /dev/sda6

I am running genkernel

After I configure grub, and install grub to the mbr using grub-install, the reboot fails, with GRUB doing nothing but display the text 'GRUB'.

Evidently, either I am doing something wrong at the grub-install stage, or there is a problem with grub.  I have had a similar lack of success with Fedora Core 6 and Mandriva installs (same problem).

The boot partition is an ext3 filesystem

My grub.conf file is as follows:

default=0
timeout=30
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
title=Gentoo Linux 2.6.17-r8
  root (hd0,5)
  kernel /boot/kernel-genkernel-x86_64-2,6,17-gentoo-r8 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda6 udev vga=0x318 video=vesafb:mtrr:3,ywrap doscsi
  initrd /boot/initramfs-genkernel-x86_64-2.6.17-gentoo-r8

When I run grub-install /dev/sda, it reports no errors.  

The device.map file contains the following
(hd0)      /dev/sda
This file was generated by the fedora installation (possibly the source of the problem?).

Any suggestions gratefully received, as I'm trying to get this system working by the end of the weekend.

Thanks in advance

When I run setup /dev/sda, I get the error 
"Error 11: Unrecognised device string"

Try setup "(hd2)"...also I think the root command needs to be adjusted to your 
partition that contains /boot.

Nope.  /dev/dvdrw isn't a "hd" device, it's cd.  If you wanted to you
could add this as "(cd0) /dev/dvdrw", but it isn't necessary assuming
you only have a single CD device.

Tab completion helps in this case:

grub> setup (        <--press tab here

This should list suitable devices.  If need be try them in turn.  The one with 
the OS in it should boot.  Also, if you are unsure where Grub's root is 
(typically your /boot partition) then before running the setup command you 
can run:

grub> find /boot/grub/stage1

[Jeff Cranmer]

Thanks Mick.

The problem turned out to be hardware related.  I moved the primary SATA hard drive cable from SATA4 to SATA1, and that fixed the problem.  One fresh install later and I was up and running.
