Just bought a secondhand desktop with Win XP installed, no install media. I want to install another opsys, but keep XP in a 8-9 Gb partition and free 30 Gb for another opsys. Thought to use the good old method - defrag & DFSEE Create Partition. However the defrag does not do its job properly, after several repetitions the files are still in 3 separate blocks with huge amount of empty space in between. "Create Partition" tells me I've got 8 Gb empty space available at the end. I suspect the problem is that there are some files (like pagesys) which XP thinks are in use. My very old PartitionMagic tells the opsys is incompatible. Any clever ideas how to go on?
