Convert Win 10 non UEFI to GPT/UEFI

In preparation for upgrading my motherboard and CPU, I found instructions on the tenforums.com on how to convert a non UEFI disc to GPT format/UEFI.  The current Z77 motherboard I have is UEFI capable but I've never used that.  I am going to use the UEFI on the new motherboard.  I wasn't sure it could be done but there are several methods to do it. The instructions I used was easier that I thought. It will save me doing a clean install with the new motherboard to get the UEFI.  The procedure requires making a backup of the current hard drive with Macrium Reflect (free version or a paid version), have a Macrium boot disk or USB Key and also have a USB key or DVD with a Windows 10 ISO (installation disc).
 

Having the full hard drive backup to a separate drive is a MUST.  It is needed in the procedure and if it all fails, you can recover back to where the drive was before the attempted conversion.  And, backups are always needed, not for IF it is ever needed but for WHEN it is needed.
 
If anyone who has a motherboard/PC with UEFI BIOS but is not using it and is interested here is the instructions that I used.

I do not use "Clone".  I tried cloning when I first got an SSD. That was with Win 8.1, and I tried cloning with the program that came with the Samsung SSD - failed, Macrium Reflect - failed, and one other cloning program - failed.  I had a full hard drive disc image (backup) that I made before trying the clones and restored to the new SSD and it worked perfect. 
 
One of our software "guru's" on the Win 7 forum (sevenforums.com) did some testing and came to the conclusion it was a hit or miss (and mostly miss) when trying cloning.  His advice was to not use it.    Another issue with a clone, it copies everything, including bad sectors and bad data when you do a clone.  A disc image only includes valid (good) data.

Make that $368!  I spent 3+ hours on the phone with Dell after buying their 1 yr software warranty to sort out the mess the local repair shop charged me for.
 
I found out they installed windows in Legacy mode not UEFI. Even more goofy was they put the boot partition on one drive and windows on the other. It worked but it wasn't right and they insisted it had to be that way. (???!) These guys used to be the best in town. Now I'll never go back except to say Dell got it right and it wasn't even hard, just time consuming. But who knows.
 
Initially I got a great deal on this laptop but now we're about @list price.

After the fact switcheroos are always hit and miss. The surest way to get things done right is to start from scratch.

Glad its working.
