Install working and Modded Mint 7 USB

[lagagnon]

If you have a spare >=8GB partition on the box then you could try ghosting the USB partition onto the new HD partition like this:

sudo dd if=/dev/sdc1 of=/dev/hdb2 bs=32256

assuming sdc1 is the USB partition and hdb2 is the spare >=8GB partition on the hard drive.
To run that dd command however, both the input and output partitions must be unmounted, in other words run the command from a Live Linux CD.
