I have my existing OS on /sda3. I want to leave it untouched. I also have an OS on /sda4 that I am willing to overwrite. The easiest path for me is to fire up Knoppix 7.6 and write it to hard disk. But I need assurance that I won't disturb /sda3 in any way. -- John Culleton Wexfordpress Book design and indexing.
