Hi,
I hope someone can help me as I have spent two days trying to figure this out!

I have an ageing Asus P8 Z77-V Pro motherboard with a Samsung 850 EVO Pro SSD (m2) attached by an adapter card to a PCI slot. This has worked perfectly for a few years, windows 10 loads fast.

I have just purchased a Samsung 970 EVO Plus SSD (m2) drive to replace the 850 Evo as I was planning to use it elsewhere. I then installed the 870 EVO plus to a PCI slot with another adapter card.

I then used Samsung Data Migration software to clone the 850 EVO to the 870 which seemed to work without a problem. I then removed the 850 EVO SSD.

However when I go into the BIOS the 870 EVO card does not show up anywhere so I cannot Boot from it, I get the error message that no bootable drive can be found?

If I now refit the 850 EVO SSD and go into the BIOS, it's there and I can boot into windows without a problem. Both drives then show up in 'This PC' and the Disk management which shows active, healthy drive with the cloned software installed.

I also note that the new 870EVO is listed as a SCSI drive! Do you still get SCSI drives :confused:

Any help appreciated.
 
Hi, KompuKare,

The M2 adapter board works flawlessly with the M/B and has done for a very long time.
The problem is the 870 Evo drive just does not work and I can't see why it shouldn't show up in the BIOS and allow to be boot from but show up in Windows.
 
Hi,
the motherboard is quite old, I have the latest BIOS which was released in 2013:rolleyes:
The card must work as the drive is shown in disk management and I can read and write data to it in Windows.
I don't think there was drivers needed when I first installed it, I just changed some settings in the BIOS.
