Windows 10: Macrium Reflect Free 7 64-bit rescue USB drive won't boot

I have an old Thinkpad SL510.
I did a clean install of Windows 10 on it.
I installed Macrium Reflect 7 Free and did a image backup.
I also created a rescue USB drive.

For the life of me, I cannot figure out how to boot into this 64-bit USB rescue drive.

I had created a 32-bit version of USB rescue drive on my Windows 7 32-bit Acer netbook.
And this Thinkpad will boot into that, but not the 64-bit version.

Can someone help?

Dual Boot 64/32 bit windows

I have windows 10 32 bit installed on an SSD drive and windows 7 64 bit installed on another drive. I want to create a partition on the SSD drive and copy the windows 7 install to it (using Macrium Reflect drive copy). Then I want to create a dual boot
environment. I HAVE READ MOST OF THE PREVIOUS POSTS AND THEY ALL INVOLVE DOING ANOTHER INSTALL - This is NOT what I want to do. I have a current image file of the windows 7 64 bit OS. I know I could use "EasyBCD" but I was looking for a Windows solution.
Any help?

 

Installing 32-bit Free Win 10 upgrade On a 64-bit Win 7

I'm going through all Computers in my house putting the free upgrade on them. I came to one of my computers. It's running Windows 7 SP1 64-bit. I'm installing the Windows 10 and I get a error saying "Processor doesn't support PrefetchW"

Okay, after all the 64-bit requires a processor that supports it

• To install a 64-bit OS on a 64-bit PC, your processor needs to support CMPXCHG16b,
  PrefetchW, and LAHF/SAHF.

So I'll do 32-bit Windows 10. However the setup will not run. It wan'ts me to do 64-bit.

I've looked in the registry and cannot find anyway to trick the computer into thinking it's a 32-bit.

I created a USB drive of Windows 10 32-bit from another computer, however, now it asks for a product key. It will not take my Windows 7 SP1 Key.
