I want to create a new, small partition where I could put the files I want to keep, so I can install Vista on my C. When I open Acronis, there's no problem yet. It displays the correct info about my current C, wich is 107Gb and around 60Gb free space. But then, I try to split it, it says the operation cannot be performed E000A0456: Unable to split the partition. Cannot change the partition's size or create a new partition on the disk. When I try to create a new partition, selecting the option to use free space of an existing partition, I get the screen where I have to select the drive from wich to use the free space. But all of a sudden, it says with my C that it has no free space on it, despite the 60Gb of free space that is actually on it. I don't know what to do, and I really would like to create that new partition. Does anybody know how I can fix this?
