Booting Ubuntu Netbook Remix from USB, migrating vanilla install packages & home

Asked by Cory Helfrich on 2009-01-21

Hello,

I received a Windows version of a Toshiba NB100 as a gift. I installed Ubuntu Netbook Remix from a USB drive following the instructions at https://wiki.ubuntu.com/UNR. Everything work great. I now would like to create a bootable USB to use as a rescue disk. How do I do this?

Thanks,
Cory

The .img file at that URL is exactly that: a "plug in, boot, erase everything" bootable image.

Thanks for the reply, Fabián!

I have installed Ubuntu Netbook Remix and made some seetings changes and installed additional packages. If I boot from the USB I created to install Ubuntu Netbook Remix, will I have to change these settings and re-install the additional packages? Is there a way to back this information up?

Thanks,
Cory

Yes, you will have to reinstall those as they will be wiped out.

To create a list of all installed packages on any given system:
sudo dpkg --get-selections > /some/file

Keep /some/file and restore it on the target system.

To restore a system using such a list:
sudo dpkg --set-selections < /some/file
sudo apt-get -y update
sudo apt-get dselect-upgrade

Because you used a vanilla Ubuntu install in your current setup, there may be packages that are not available in UNR (as it uses an lpia architecture).

Regarding other settings you can try making a full backup of your /home directory on a ext3 formatted key (this preserving file rights, ownership, etc).

Boot in recovery mode in your UNR install, then rename the existing /home dir (as safety measure, don't erase just yet), then recover the backup /home in its place.

Booting in recovery mode is not easy, but can be done :) See:
