[SOLVED] Grub Error 2 while trying to boot into Gentoo

[meierfra.]

Yes that will install Grub to the MBR. But isn't grub already installed in the MBR? Or did you add Ubuntu to the Windows Boot loader ?

[Morrad]

I suppose it is. When I turn on my computer, grub comes up, not some windows program. Is there a way that I can check and be sure that is the case?

[meierfra.]

Copy and paste this into a terminal:

sudo dd if=/dev/sda bs=512 count=1 2>/dev/null | strings | grep -i grub

If it returns "Grub" you have grub installed in the MBR.

I do have grub in the MBR then, thanks.

As I'm trying to install the new version of grub, I get the following error though. (I already purged and apt-get installed the existing grub install, by the way).

sudo grub-install /dev/sda

/dev/sda does not have any corresponding BIOS drive.

Try

sudo grub-install --recheck /dev/sda

[Morrad]

I take it back, I added a --recheck switch to the above command, and it installed. Needed to renew the device map after I purged the old one.

I'll go test it out now.

[Morrad]

I'm happy to announce that the problem did appear to be with the grub version I was using, not my hard disk. After reinstalling, grub is able to see all my linux partitions without any issues, and I can boot into Gentoo.

Thank you all for the suggestions and help. Marking thread as solved.
