Cloning M.2 issues with HP Spectre X360...

Using Acronis TI Home build 6613 to clone my 256Gb original (Lite-on) laptop drive to either of a Samsung SM951 512Gb or an XP941 512Gb drive.

I have attempted this in a number of ways, including following the "clone your laptop guide" provided by Acronis, and each has failed at the reboot stage... the HP simply says... operating system not found or words to that effect, then offers to try to repair the situation, but can't.

Before I explain the various methods by which I have attempted the clone, let me say that I took a straight clone of my XP941 in my PC, which runs Windows 8.1 64-bit, and the laptop obviously made some adjustments during the bootup stage adding drivers and the like I guess, and then ran fine, so I know the laptop is happy with the drive intended to go into it.

Another minor, but possibly important fact, is that the Lite-on original drive is a slightly different form-factor... it has two slots (I believe it is called an M+B) and the Samsungs only have one slot (an M I believe).  Whether that complicates things or not, I am unsure, but mention it just in case.

The Laptop is a brand new HP Spectre X360 running the new Skylake i7-6500U cpu and an M.2 drive as standard, and Windows 10 64-bit.

Methods..

1. I have a motherboard that has two inbuilt M.2 sockets (M-type), so cloning from my boot drive to the other on the PC is simple.  That's how I did the clone and got the PC build to work in the Laptop.

2. I have an M.2 PCI-E card (also m-type) that came with my Asus 3.1 motherboard, so used that to do a three-way, with the PC O/S in it's normal slot and the Lite-on in one of the other slots and cloned driectly from one to the other as neither were in use.

3. I have an external B-type USB 3.0 case that I popped the Lite-on into, put one of the 512Gb drives into the laptop, booted from my USB Acronis (UEFI) drive and cloned from the Lite-on to the Samsung in the Laptop.

4. Install either of the Samsung drives into the laptop and try to do a factory rebuild from the USB Recovery Media that I created on day one.  Errors every time trying to find the installed drive, which I struggle with, as the same drive with a windows 8.1 O/S already on it works perfectly.

5. Also tried imaging and restoring in various positions, but to no avail.

With the exception of getting the Windows 8  build to work perfectly, nothing else seems to work, and I need help.

---- edit

Sadly in a way, the point is moot now... I found another member had posted here that his attempts had also failed, and he ended up using Macrium Reflect free to do the job.

I did the same... it didn't work immediately, in the sense that I got the same result, but the Macrium software offered a repair boot option, and it seems that did the trick... I had to boot into safe mode, and that worked (normal did not), but once I got it to booting in safe mode the once, it obviously sorted itself out completely, and you'd think the Samsung drive had been in there forever, except for the huge performance gain of course.

Now all I want is the next generation Laptop that runs PCI-E 3.0, and we'll be back up to 2200mb/s read and 1600mb/s write again.

Thanks for reading and I hope this helps someone else until Acronis solves this issue.
