Problems with Grub menu after installing Karmic from Karmic with debootstrap/chroot

[GeoMX]

I'm currently running Ubuntu Karmic in a dual boot environment (Windows 7) and I'm trying to make a clean Ubuntu installation to a new hard drive to be used with another system.

I've followed the Ubuntu documentation guide at: https://help.ubuntu.com/9.10/installation-guide/i386/linux-upgrade.html#id2628424

and was able to follow all steps without problems. However, I have one problem with GRUB:

The new disk will hold only one OS (Ubuntu), so I'd like the GRUB menu not to appear, this is the case when booting from the new installation for the first time, but for the next one, GRUB menu appears and stays there no mater what I try. I've tried editing /etc/default/grub but when running update-grub I get this erros message:

grub-probe error cannot find a device for /

I think I got confused with the partition configuration, so could someone please give me some advice for configuring the new system correctly to work with GRUB?

Woudl it be possible to use a Live CD to reinstall and configure grub?

I've just switched to Karmic a week ago (I've been working with Hardy) and I'm a bit confused with the new version of grub, I find it a bit hard not to be able to edit the files but run update-grub instead.

Is the drive still on your system or have you moved it to the new system? Drive numbers probably changed.

Yes you can reinstall grub2

Thanks a lot for all your help, those links provided me with enough information for understanding the new GRUB :).

However, I now have a more specific problem, we are trying to run a read only linux system, but don't know how should I proceed in order to edit GRUB since it relies on "normal" partitions (correct partitions declared in /etc/fstab and device.map), but when I try to configure GRUB inside the read only system, I get this GRUB error message: "can not find a device for /".

I'm basically following these instructions:
http://www.logicsupply.com/blog/2009/01/27/how-to-build-a-read-only-linux-system/

for setting our read-only system, do you have any advice on how to proceed in order to be able to configure GRUB in such a setup?

Not quite sure if it is the same thing or not. But I used this to directly boot ISO which are read only.

If you boot from a CD with no hard drive that is a read only system. I saw several years ago a minimal floppy only system where the floppy was set to read only - I think it may have been to convert an old computer to a router.

You may do better with a new thread with your new subject in the title as those with more interest in special configurations will read the thread as opposed to boot issues.

Thanks again for your help, I'll make a new post and mark this one as solved since now I'm able to configure the GRUB menu for a "standard" installation.
