Hi,
I've just done a stage 1 installation of gentoo (2005.1 universal livecd) on the following system:

  • AMD64 3000+
  • Gigabyte K8nf (nForce4 chipset)
  • 2 x 200GB WD SATA drives
  • Generic IDE cdrom x52
  • 2 x OCZ dual channel premier 512MB DDR400

Everything went well but when I got to rebooting the system refuses to boot from the hd as if no boot manager is installed. My grub.conf is standard and has only one entry (no splash screen). Both grub manually and grub-install report success in writing to the mbr. No raid is active, both in the motherboard and software. No pata hd is connected.

I used a simple partiotioning scheme:
Code:
/dev/sda1 ext3 /boot
/dev/sda2 swap
/dev/sda3 ext3 /
/dev/sda5...9 other partitions not yet in use

grub detects sda as hd0 and can see the partition type. I used (hd0,0) for sda1.

I have tried to reinstall grub and didn't get any results. I have tried to test all available bios options, even those i'm certain that are incorrect and got nothing. I tried searching the forums but got nothing except a post from a guy with similar problems that wasn't resolved.

Is there anyone that's familiar with a similar kind of problem and can help?

edit:
To be perfectly clear - I dont' get any grub error. The system simply jumps to the next boot device.

While you were partitioning your disk, did you make /dev/sda1 bootable? In fdisk, if you press p to see your partition scheme then there should be a little * by /dev/sda1:
Code:
Command (m for help): p

Disk /dev/hda: 30.0 GB, 30005821440 bytes
240 heads, 63 sectors/track, 3876 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Device Boot    Start       End    Blocks   Id  System
/dev/hda1 *        1        14    105808+  83  Linux
/dev/hda2         15        81    506520   82  Linux swap
/dev/hda3         82      3876  28690200   83  Linux

If the * is not there then type a and then chose the partition (1 in you case by the look of it). Then save and exit fdisk (w) and try again.

I hope this helps.

Thanks, but I did make it bootable.

Any other ideas?

Hi all,
To all those it may concern, I've managed to solve this problem by:
1. Moving the cdrom from master to slave (I'm usure this is relevant, but I did it to be sure no conflict could occur)
2. Disabling network boot via bios.
3. Disabling the raid controller completely via the bios.
I'm usure which did the trick, but if anyone else encounters this problem and finds out, please post it here.
