Restoring a Windows boot entry

So you're messing around and delete the efi boot partition. After restarting you realise that you can't boot into Windows, so what do you do?

1. Flash a Windows image onto a usb stick
2. Boot into the live media
3. Go to Repair your computer > Troubleshoot > Command Prompt
4. We first need to make sure that the C drive is mounted:

   diskpart
   list volume
   # Figure out which volume is the C drive
   select volume X
   assign letter j
   exit
   

5. Add the partition to the boot configuration

   bootrec /rebuildbcd
