Hi. I need help.
I have an Asus n752vx laptop. It has 2 drives. Primary SSD M2 SATA Micron 512GB, and secondary mechanical HDD 1TB 7200rpm.
I have changed the mechanical HDD with new SATA SSD (Samsung EVO 870)
But now I have problem in bios, cannot set to boot from original M2 SSD.
When CSM is disabled in bios (default setting), I cannot select M2 for boot, Windows boot priority only offers 2nd SATA SSD
After booting it say cannot find OS on drive... When enable CSM, I can set in boot priority the M2, but wont boot again.
When I take out the new SATA SSD, and disable CMS, it boots from M2 drive.
So it works only with CSM disabled, and without the new SSD Installed...
(when both SSDs are installed it wont boot from original M2 system drive.)
