TeraByte Unlimited

I see that IFL now comes in 64 bit and 32 bit flavors. I have a computer with a 64 bit motherboard, but I installed 32 bit Windows 10 on it. Which IFL should I use with it, 64 bit or 32 bit? What issues may arise from using an inappropriate version?

msinfo32.exe reports BIOS Mode is Legacy, but when I get into the UEFI, that is nowhere apparent.

whichever works, just needed the x64 kernel because of UEFI64 systems with address spaces in the 64bit realm that otherwise could hang on the handover. For most new systems, just use the x64 kernel.

So if the backup passes Byte-for-Byte validation, the backup will have "worked"?
