Be sure that you remove the old drive BEFORE you attempt a boot PLUS be sure the new drive is on the SATA port you were booting from.
If that fails, use some other clone app.
Feeling a bit stuck and frustrated since my system has been down all day -_-
I had a 1TB drive almost full and installed a new 2TB to replace it. I used EaseUS to clone the drive thus transferring the Windows install (which I've done before on another system). The clone process seemed to work fine, BIOS shows my new drive on the list (after removing the original 1TB), but I can't actually start the system (keep getting "No boot device found"). Been running startup repair for almost an hour now with no apparent progress. Anyone have any other suggestions?
