Windows 8.1 - Won't boot (0xc000000f), bcdedit fails

I’m pretty much stuck at this point. So, backstory:
Windows was installed on one of the SSDs currently in my tower. I bought a new SSD to install Windows (8.1 64 bit) on. Windows installation went fine, booted up, and formatted the old SSD from within Windows (this seems to have been a mistake, but I didn’t realize that at the time).

Despite formatting the old SSD, whenever I tried to boot I was told that there were 2 Windows installations. Apparently, when I formatted the old drive, not all of the partitions were removed.

So, I booted up with the repair utility, went into cmd, and deleted the non-primary partitions on the old SSD (there were 2 – think they were system and recovery, although I’m forgetting now).

Reboot – computer won’t boot. Getting the 0xc000000f “The boot selection failed because a required device is inaccessible” error.
Troubleshooting so far:
Automatic repair doesn’t fix anything (I’ve never had luck with it though) If I go to install a new version of Windows, the drives and partitions are all there. The SSD is functioning, I at least know that.

I’ve essentially gone through this guide: https://neosmart.net/wiki/recovering-windows-bootloader/Unfortunately, I’m not getting anywhere. I’m not even entirely sure how to describe the errors I’m getting, so I’ve just included pictures of every step

Am I completely screwed at this point (i.e. reformat / reinstall)?

Thanks

The Drive 0 you are showing the partitions on is a GPT drive, and if it were the boot device, it would have an EFI partition. Since it does not, it has been corrupted or the other GPT drive (119 GB) is the Boot drive.

Check the partitions on it, and if it shows the correct partitions, make sure and select the Windows Boot Manager in the bios as first boot option. If you were to have the boot files on an MBR drive, you would need to set that drive as first priority.

If you don't find any EFI partitions, you may be booting to one of the MBR configured drives, which would need an active partition.
