Hello good people of TH.

I'm relatively new to the SSD business and never had to worry about those things, so forgive me if I get something wrong from time to time. So, recently I bought a new SSD and I only had an old HDD before. I used the Samsung Data Migration tool to transfer Windows and other programs and data onto my SSD. This was very troublesome already because of several reasons. I managed to transfer it finally after defragging my old HDD.

So, after the transfer I hooked up my SDD via SATA and I seem to have forgotten to plug in the HDD. So far so good. I booted up my system, it works and is very fast. I noticed I didn't have access to my HDD but I thought I'd fix it later. So later, I looked into my case and saw the SATA cable was not connected. I plugged it in and wanted to boot; but: Bootmgr is missing.

I then tried several things in UEFI/BIOS (nothing worth mentioning I think though) and nothing worked. I could boot up from my HDD though. I googled this error and found things like using Bootrec, which I tried using after downloading the Windows 10 ISO on my USB stick. Result: Bootmgr is missing from both HDD and SDD (that might be my fault though, I unplugged the HDD now). In any case, I tried to use Bootrec /rebuildbcd among the other options and the command prompt then promisingly told me that my C drive (SSD) had windows installed but wasn't added yet to the "starting list" or something similar. I pressed "Y" to add it, but the prompt told me that it "couldn't find system device" (I have it in German, this is a literal translation).

So now I'm sitting here, I have only my SSD plugged in with my Windows installation, but Bootmgr is missing even after I have tried many many things. What was weird about all this is that I managed to boot on my SSD and AFTER plugging in my HDD again it told me that Bootmgr was missing, even after I unplugged the HDD again. So now I simply can't boot either SSD nor HDD. Can anyone help?

Thank you guys!

I don't like cloning ssd, weird things can happen.

if anything on SSD you want to move to hdd, try this: http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/

try this using your Win 10 USB:
change boot order so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose start up repair - this will scan PC and maybe fix this - will ask for logon info


Since you have all the data on hdd, I would fresh install win 10 onto ssd with hdd out of machine

Use that win 10 ISO you have on USB
change boot order so USb first, ssd second
follow this...

Once win 10 reinstalled, try plugging hdd back in. Make sure SSD is at top of boot order and if you can, remove hdd from list. At some stage you might want to wipe hdd so its copy of win 10 doesn't confuse PC again.

Since you had win 10 on both drives and they were clones win 10 might have gotten confused. Especially if you left HDD at top of boot order in BIOS
