LiveCDCustomizationFromScratch = 'grub rescue>'

Kenny_Strawn · 08-27-2010, 03:57 PM

Here is the instructions I was following:

https://help.ubuntu.com/community/Li...ionFromScratch

When I got to the point where I had to install my own packages in the chroot:

Code:

apt-get build-dep gnome-shell #error: Read-only file system

Now I don't know about you, but how come the file system registered as read-only? I did mount an external drive in the ~/work directory, but did not use the 'ro' option.

Edit: And when I tried to unbind /dev, it exited 0 and then the drive wouldn't unmount. When I rebooted after that, I got the 'grub rescue>' prompt.

Need further details. All previous apt-get install are working fine? eg,

Code:

apt-get install --yes ubuntu-standard casper lupin-casper
apt-get install --yes discover1 laptop-detect os-prober
apt-get install --yes linux-generic

just only your own packages?

That doesn't make sense. Need further details.

Yes. It's when grub2 was installed (Apparently, Lucid and Maverick require GRUB 2 and Plymouth to also be installed) and I (mistakenly) installed GRUB to the MBR of /dev/sdb (my external 500GB SimpleTech hard drive) that it came up with the "Read-only file system" error.

I actually was up to the point where I had to customize, i.e. install the main packages in the repository.

So problem solved?

No. Apparently now the drive won't mount. I tried manually mounting the device in the terminal and it says the device is busy. Same thing when I format it.

As an update to the previous post, trying to mount /dev/sdb in /mnt results in a hang of the mount command. Possible infinite loop in mount?

I don't have the context what you are trying to do. Are you at the step "Partitioning your Usb device"?

Generally speaking, all the symptom that you described means something wrong with mtab.

Without your detailed steps and (error) output, it is very hard to say what's wrong. Have you tried use mount to show mount list and umount everything that shouldn't be there?

There is no error output, just a freeze/hang and timeout.
