Will I lose dual-booting if I clone HDD to NVMe using Macrium?

☺
There's an excellent tutorial how to use Macrium Reflect to clone from your existing HDD to a new NVMe M.2 SSD. at UPDATE: Using Macrium Reflect Free to Clone Windows to a Bootable M.2 SSD - YouTube

However --

My original HDD is dual-booting Win 7 Pro 64-bit and Win 10 Pro 64-bit, and they are in separate partitions on my existing HDD.
(FYI - I use the excellent apps iReboot and EasyBCD to reboot into either the 10 or the 7, and the default is the 10. And my HDD is already GPT-UEFI although I do not use Secure Boot and I do not need a password to reboot or log on to my PC, which is at home.)

QUESTIONS --

1) Will there be a problem when I boot from the NVMe SSD to which I cloned the HDD? Will the NVMe still have the dual-boot info?

2) MOST IMPORTANT -- If I run "Fix Windows boot problems" from the Macrium PE environment, as suggested at the end of this excellent video, will that preserve my dual-booting setup? (I think that is the same as asking whether my dual-booting EFI partition will be preserved, but not sure.)

3) If I lose the dual-booting capacity, will I be able to recreate it using EasyBCD? After all, the two partitions (Win 10 and Win 7) should be there.

Thanks.

The very first question to answer is how are you going to connect an NVMe SSD to the Dell 7010 MT which has no M.2 slots?

I've done that once before successfully to an Optiplex 7010 a few months ago, but that was single-boot into Win 10 Pro 64-bit. It's now running 15 times faster on CrystalDiskMark, at little cost.

So, now I want to do it again, but this time the source HDD is dual-booting as I mentioned.

Unless I'm missing something, I don't think the 7010 + that article makes a difference. It's a Q of whether Macrium Reflect cloning preserves dual-booting, especially if I run "Fix Windows boot problems" at the end.

Running the Fix Windows Boot Problems routine will ask you which system partition you want to fix, and which Operating Systems you want to add to it. You should be fine after running that utility.

The only "fixing" is the BCD file in the EFI system partition cloned to the NVMe SSD which Macrium will take care of.

OK - sounds like it's good - thanks.

Unless there might be an issue with Windows adding the NVMe storage driver. It would be best to add the NVMe drive, and boot into each installation of Windows and make sure that the NVMe drive shows up in disk management. That would indicate the NVMe driver was installed in Windows before cloning.

NavyLCDR - interesting suggestion - connect the NVMe drive before running the steps in the amazing article I linked to? Just to see that the 7010 (in each of Win 10 and Win 7 booting from the HDD) recognizes the NVMe for storage purposes, and that therefore each Win has the drivers for the Samsung NVMe?
I like it.
