making an ISO image

[Glenn / Lenny]

Hi Rob,
One thing did not work, and that may be why the chroot /mnt does not work...
The command mount -o bind /proc /mnt/proc
gives me the message:
mount point /proc does not exist
and when I run chroot /mnt
failed to run /bin/bash, no such file exists.
I am logged in as root, that is why I did not write sudo.
Thanks, I hope I can get the GRUB fixed up.

What have ou tried when fixing your old install on sda2.

That should be recoverable quite easily.


You need to mount the /dev from your currently running Ubuntu to the
mounted partition.

For example

mount -o bind /dev /mnt/dev

Assuming that sda2 is mounted to /mnt


Repeat that for sys and proc

mount -o bind /sys /mnt/sys

mount -o bind /proc /mnt/proc


Then change the root file system using the chroot command

chroot /mnt

Now your computer thinks you are actually using sda2 instead of your USB.

If you want to install your boot loaded from sda2 to your hard drive
type this:

grub-install /dev/sda

update-grub

thene xit the chroot

exit


Good luck.
