Have just installed Win7 64bit Home PRemium on a Samsung 840 Evo SSD drive, GPT. I need to make a disk image of this clean installation. Is there some free software to do it? Have looked on the web and most are MBR, not GPT, and most seem to clone to a new drive, rather than store an image in one big file. I know Acronis do it, but was hoping to get something free!
