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 (I can't actually post them though so I just included a photobucket link).

Am I completely screwed here (i.e. reformat and reinstall?)?

Thanks

  • What does DISKPART -> LIST VOL display? That will show your volumes (with drive letters). I've got a feeling you're following the tutorials literally and not using YOUR drive letters for the current WinRE session. C:\` within WinRE might not be your actual system `C:\` - hence the "Path not found" and "File not found" errors...

You deleted the boot partition (EFI System Partition or the active partition) on the old SSD.

You could restore all partitions you have deleted - google and find some tool (I would suggest "TestDisk" for partition recovery).

You only need either an "active partition" on old SSD if disk uses a MBR or an [EFI System Partition (ESP) + Microsoft Reserved Partition (MRP)] if the disk uses a GPT.

Then you can repair the Windows BCD.

If second SSD (where you installed Windows 8.1) has ESP and MRP partitions just put it as first disk in firmware and do a Repair Windows BCD.
