So I just got a new 7200 RPM WD HDD with a 64 MB cache and wanted to clone windows 7 over to it, well it turns out it doesn't work for some reason it brings me to the acronis (the program WD give you to clone a hard drive) BIOS and then i see a window pop up but before I can do anything windows starts for some reason. so as a work around I created a backup of windows on the drive I want to clone and then backed it up to the drive I want to send it to but then when I go to the BIOS and set it so it boots off the new drive it says BOOT MGR not found so I have to go backa nd select windows boot or whatever : / any solutions would be appreciated
