A bit of an embarassing problem (Restart Loop, Windows 10)

[Guest]

I was eagerly looking forward to upgrading my Windows 7 PC to Windows 10, so I started the upgrade process and everything went smoothly. I got past the "use express settings" prompt to the "Setting Things Up - 99%" screen, when, on accident, I kicked the off switch on the power strip my computer is plugged in to.

Now when I try to boot, I just get the little circle dots for Windows 10 startup, followed by my computer restarting endlessly.

I've tried following these instructions, but I get stuck since the "attrib c:\boot\bcd -h -r -s" command tells me that "c:\boot" is an invalid file path. I've tried running the regular startup repair tool too but it just tells me that it isn't able to fix anything.

I was planning on reinstalling from scratch anyway, but the way I understand it, I need to upgrade my Windows 7 version before I can do a fresh install of Windows 10, so I would still like to fix this failed upgrade before wiping everything, lest I have to install Windows 7 and all its updates again.

Thanks for the help.

EDIT: A bit more information: bootrec /rebuildbcd finds two installations of windows (C:\windows and C:\windows.old). I'm able to add c:\Windows and discard c:\Windows.old, but then I don't get "operation completed successfully" as expected. Instead, I get the "device not found" error.

I would just reinstall Windows 7 cleanly and use the same product key (If it's OEM, just let it pull the key from the BIOS), then upgrade to Windows 10 again. If you get and issues with your Win7 key, then it's possible that it's already converted to a Windows 10 key.

I know it the "long way" around, but at least you want have to do any further trouble shooting.

Hope this helps,
