I got the message 'BOOTMGR is missing, press Ctrl+Alt+Del to restart' and I worked on repairing it for several hours, but nothing on any threads worked. I plugged a new SSD into the PC and booted up a fresh install of windows on it, but I still can't repair the other drive. I would really appreciate it if there were a way to either fix the drive in question or to transfer all of my settings and files to the new drive...thanks :)

Have you tried connecting old HDD with Windows USB installer and then trying to repair OS? It might rebuild the boot loader partition. If you can fix the install you can then clone it to the SSD to keep all files and settings.

So what happens when you boot to the OS using your freshly-installed OS on your SSD when the SSD is the ONLY drive connected in the system? Presumably it boots to the OS & functions just fine, right?

Now you shut down the PC, connect your HDD and boot to the SSD with that HDD now installed as a secondary drive in the system. Does the HDD show up in Disk Management with a drive letter assigned to it? (Assign one if not.)

Assuming the HDD is listed in DM (with a drive letter assigned to it), can you access all the data on that HDD? Any problems?
