Hi,

I am having trouble with my new "Crucial M550 256GB mSata SSD" and Lenovo T420, I have tried in various ways, but I can´t boot from the mSata.
Always get a black screen and a dash on top left corner.

Install SSD without problem, BIOS and Windows recognize it.
SATA is settled as ACHI
UEFI is settled as BOTH

Then I try:
-Clone Disk. The disk is cloned I see my files and system partition. Use EASEUS to clone.
-Install windows from Lenovo Factory Recovery.

Then update Bios and drivers and went back to deal with the two option mentioned but always achieving the same.
Always disconnect my original HDD and sometimes force start from BOOT list selecting the source.

Someone can help me with this problem?

Thanks.
Regads.
