Grub Error : Selected disk does not exist

Hello,

I have Ubuntu 4.10 successfully installed on my Samsung SATA hard disk. GRUB is also thing and good boots.

Unfortunately, I can not start Ubuntu, it comes the message: Error 21: Selected disk does not exist

GRUB knows my S-ATA Samsung hard drive (when installing from CD, it was detected).
My two ATA133 disks
provides GRUB without problems, however.

What can I do? Does GRUB (yet) no S-ATA HDs?

Does anyone have advice?

Thank you

I'm not sure, but i think that grub counts disks, not controlers.

Have you tried

Code:

---

rootnoverify (hd1,0)

---

Hi,

Note that "Partition table entries are not in disk order"

while in fdisk, go to "x extra functionality (experts only)" and then "f fix partition order"

Try rootnoverify instead of root. But it does seem like a strange error; does the disk show up in BIOS properly? Linux will bypass BIOS, but grub alone can't do that.
