just use the livecd to move files over
Move files from where to where?
Most liveCDs I've used will show your hard drives and partitions, with generic names, on the desktop, such as hda1, hda2, hdb1, etc. It's up to you to mount them one-by-one to discover their contents.
If you want to move files from one partition to another, you must mount the target and object partitions in order to move files.
If you want to copy files from the liveCD to a partition, the target partition must be mounted before you can copy files from the cd.
If you want to copy/move files to the cd, you can't do it directly. You will have to unpack the .iso into a folder somewhere, add files to it, then re-make the .iso image.
