Just to clear up some terminology, by "reset" do you mean "Power Off"?
because there's a "Reset" which means to completely reinstall Windows.
Anyway I'm wondering if you are anywhere near a Microsoft Store and you could take it in? This might be your best option.
Try to force it into Recovery:
Press and hold the power button as soon it starts booting. This will obviously shutdown Windows incorrectly, but by performing the action three times, Windows will automatically boot into the
Automatic Repair environment, where to can diagnose and fix the operating system.
Otherwise you will need to boot to a Recovery USB
If you don't already have one you need to download a recovery image from Microsoft.

Not sure which screen you'll get but options might be Troubleshoot, Advanced Options, to get to Command Prompt
You'll probably have to enter the Recovery Key it will tell you where to get it.
Http://windows.microsoft.com/recoverykeyfaq follow the instructions...
Login, you'll get a tiny Command window... tap the black icon in upper left select properties:
I like to use Font 12x16
Layout -
Buffer Size width 120 height 3000
Window size width 120 height 45
OK
Change to C Drive
C:
Delete this file... to kill pending updates.
Navigate to
C:\Windows\WinSxS\ folder, search for a
pending.xml file and delete it.
Cd windows\Winsxs
Dir *pending.xml or just *.xml
File may have big number prefix.pending.xml
Del *pending.xml
If you have maybe downloaded any large files etc. you can remove, do it now.
or just try Restarting , use Exit command follow the menu.
