I just got a new 512gb SSD and wanted to transfer my 150gb boot partition from my 2tb HDD, I used EaseUS todo backup to clone the partition every thing appeared to go all right the cloning finished I shut down the PC, removed the HDD to test SSD and this is where the issues started. I got the "reboot and select proper boot device" screen I checked in BIOS and confirmed that it registered it. I assumed the cloning had just failed(more on that latter). I reinstalled the HDD and found my self at the same "reboot and select proper boot device" screen. At this point I think the cloning must have corrupted the drive but to be sure I test the HDD on my 2nd PC where it boots up just fine (I also tested the SSD and had to run recovery on a windows install USB to get it working) so now I go back to the problem PC and try the HDD from my second PC, same issue. I try swapping cables , updating bios ,reseating ram, powering the drive from another PC all resulting in the aforementioned screen. The only time I got it to boot into a drive was when I installed the SSD and ran a clean install. Ideas?
