Thanks for your key! I'll try soon. I want install 7 on my SSD drive via "VHD file" because it's faster then acronis to restore the OS and a lot of other reason... The main problem is that the pagefile.sys file doesn't reside inside the vhd file; with 8Gb of ram I need at least 6Gb of pagefile and the SSD is only 64Gb. The secondary problem is that I've read all the files that are written continuously, like the swap, temp files etc etc, it's best to save them on a traditional disk. P.S. Sorry for my bad English
