Safely repartitioning harddisk without backup requirement
I have partitioned a harddisk three times before-blank to Knoppix, added Debian, then added Windows XP, all on one computer, so by no means am I asking for a walkthrough of the partitioning process.
I am planning to add a partition for Linux from Scratch onto a harddisk with an existing OS, Windows XP. However, when I searched online on how to add an partition using the lesser accommodating XP as the pre-existing system, each result warned that the existing partition would be destroyed, unless I created a backup of the system. I have five years worth of data on that harddisk, and lack sufficient disk space for a backup.
Using QtParted, I was able to add a partition to an harddisk with an existing system,(Debian), without destroying any data-at least according to my memory. I would like to be assured that there is a way to do just that when I am adding Linux to Windows, rather then the more familiar other way around...preferably without the employment of XP's standard partitioning program, Disk Management.
