Hi, I have a 60gb computer. The c: is 20gb and is Fat 32. My d: is 40gb and NTFS. Because I only have 3gb free on my c: but about 30gb free on my d:, I wanted to increase the free space on the c: by taking about 20gb from my d:. When I perform this operation and reboot the system for the changes to take place, it tells me error: disk not found, hit any key to reboot. When the computer then reboots everything loads normally and acronis states complete, but the changes haven't taken place. Please help, my computer is seriously slow which i assume is due to the lack of free space on my c:. Any help gratefully appreciated. P.S I have bought version 10.
