MBR screwed. USB Boot and load existing Windows as a temporary measure?

Help! My Windows 10 Master Boot Record has kicked the bucket.
As a temporary measure, I would like to throw a Boot Loader on a USB drive and configure it to load the currently installed Windows, bypassing the MBR of the current OS drive.

I used to be a nerd and I knew how to use LiLo to load any choice of OS... but that was a long time ago. I seem to be running in circles with Google trying to find the resources.

Can anyone point me in the right direction?

I'll be picking up a new HD and doing a re-install this weekend... but I have business materials on my Windows RAID that I want to get at.

Thank you all in advance!
