I’m on Windows 8 and need to upgrade my main (boot) HD. The old drive is IDE. I installed a new WD10EZEX on SATA, and used WD Acronise True Image to clone the old drive to the new. The resulting drive/partition isn’t bootable. Windows Disk Management shows its status as “Active, Primary Partitiion”, but not “Boot”.
I tried removing the old drive, and directed BIOS to boot from the new drive, but it failed with a message of “required device is missing”
How do I make the new drive/partition bootable?
