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.
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 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?
