Booting from SSD

I have the Lenovo T440p laptop running win8.1. It comes with a hybrid SSD as a cache. I am attempting to replace this with a larger SSD and use that as my boot drive but the machine refuses to boot.

So far....
The Lenovo requires an M.2 NGFF 42mm (2242) SSD to fit the SSD cache slot. I have a 256gig MyDigitalSSD Super Boot Drive (SATA III/6G) which I think I have successfully installed.

When first installed the BIOS saw it but Windows Explorer didn't. I went to Disk Management and gave it a drive letter/quick formatted it and Win was able to see it. I was able to clone the OEM version OS from my main HD to the SSD using EaseUS Todo backup which appears to have been successful but.....

The problem
The machine refuses to boot to the SSD. I have changed the boot priority in the BIOS and the machine ignores this and boots to the original HD.
Removing/excluding the HD from the Boot order list results in the SSD also disappearing from the list.
The F12 temp boot device menu is likewise ignored.
Physically removing the HD just means the machine wont boot at all. It starts, displays Intel Boot Agent but that just fails with an error PXE-E61 Media Test Failure, Check Cable and exits to the F12 temp boot device menu

Not being particularly technical I am now at a loss. I have tried adjusting the various BIOS settings (such as UEIF/Legeacy support) - and then changing them back again but nothing seems to make a difference.

No idea if I have somehow misconfiguration the drive in Win, or its just not compatible or if it is because I cloned the OEM OS or maybe because I put my pants on backwards this morning.

Anyone able to offer some advise please?

Is this what you did and failed?

I looked at the link and thought "well that ain't helpful... that is what I already tried". Then of course I stopped and looked through it step by step and of course spotted the one small detail I had missed before. Re-cloned properly and it is now working.

Thanks guys.

So this is not the OS boot.

"the SSD cache slot."

These cache systems are often upsized with arcane methods. Back to the laptop maker you go.

Re: boot issues

Usually, startup repair from the Windows install disk does a good job to remedy boot issues. Worth a try.

Maybe this one won't clone?

Maybe this one needs the other method. Which is....

Install the new SSD and HDD (unless you have backups of what you can't lose) then use the factory restore media.

How I would try this.

Disconnect the data cable to the old Hdd. so only the SSD is install, now try to boot up the computer. It may first go through a repair process and if the SSD has been clone properly, then it should work. Good luck.
