Bug Description

Binary package hint: grub2

With the latest version of grub2, update-grub reports:

grub-probe: error: Cannot get the real path of `/dev/sda'

And if I use grub2 via the grub chainloader, it repeatedly prints "Syntax error" and does not boot.

I have an internal IDE hard drive.

Please try what was suggested in the Debian bug report:
"This is a bug in GRUB itself not grub.cfg. Just (re-)run grub-install."

This error comes up on installing the 2.6.24-10-generic kernel.

If I run:
# update-grub
grub-probe: error: Cannot get the real path of `/dev/hda'

I tried what Tormod Volden suggests above:
# grub-install /dev/hda
and get the same error.

What I suggested above was for the other bug: You reported two bugs in one report, which ends up in confusion...

Can you please run: bash -x /usr/sbin/update-grub > update-grub.txt 2>&1
and attach the file update-grub.txt?

I noticed in your original report it was /dev/sda, and now it is /dev/hda. Is this correct? What does "df /" say?

(however, running grub-install /dev/sda results in the same error)

I have attached the file you requested.

Does it help at all to run "grub-mkdevicemap" begore running "update-grub" ?
Is the content of /boot/grub/device.map ok?

This should be fixed in Ubuntu Intrepid. Please could someone confirm?
