Inaccessible Boot Device

So I'm pretty stuck on this one.

Last night I was rendering some video, while watching another video, when everything started to lag really bad. My rendering software crashed, as did Media Player, and Windows 10 (anniversary edition) basically had a seizure. No brainer, I thought, just reset.

Lol no.

Windows wouldn't boot any more. I got endless loading loop with the windows logo, and every third attempt I got endless "preparing automatic repair" screens. I know they were endless, because I left the latter overnight and it didn't change.

For ages I thought it was something to do with the MBR, so I created a Win10 installation USB to use as a recover media. I used commands to repair the boot environment, with no success. I was able (intermittently) to boot into safe mode, but never into Windows properly.

In the end I connected a second, new SSD and did a fresh install of Windows 10 to that. This install I'm able to boot into, no problem. So from here I used EasyBCD to create a dual boot option with the old SSD.

So now I can see both Win10 installs in the boot environment, but every time I select the old install I get a "Inacessible Boot Device" blue screen, complete with a perfectly useless QR code (why Microsoft?).

I know Windows likes to share boot environment information, so I'm thinking now that this can't be an MBR/ BCD issue as I've got one working install running parallel to the one that isn't. Besides, I've tried running all the command prompt fixes in the recovery environment that I can find (‘bootrec /rebuildbcd’, then ‘bootrec /fixmbr’, then ‘bootrec /fixboot' etc) and none of them have worked.

Frankly I don't want to have to start over with a fresh install of Windows 10, I'd much rather get back into my old install.

Anybody got any advice?

Two ways to fix this
1. boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
open command prompt and type chkdsk /f and press enter. Might take a while. http://www.toppctech.com/inaccessible-boot-device-error-fixed/
2. The more common way to fix it is fresh install
If there anything on hdd you want to save? Try this: http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/
Once you copy everything off you want to keep, follow this: http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

clean install may want to wipe hdd so make sure to copy everything off you want to keep
