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.
 
You can't really expect an old Z77 board to be able to boot from some random PCIe slot.
I am surprised that the m2 SATA worked actually.
I have a P8Z77-V LE (if I recall the model correctly) and I have NVMe drive on a PCIe adapter but of course I don't boot from that.
Instead I boot of normal SATA SSD.
Once in Windows, the NVMe drive is useable.
Do you not have any other drives too boot from?
 
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.

If the motherboard doesn't recognise the newer 970 it may need a bios update.

Do you have the latest bios for your motherboard ?

Does the m2 pci card need drivers ?

Does the m2 pci card support m2 nvme drives?

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.
 
Well, your model numbers are all over the place in the OP.
EVO 850 is m.2 SATA.
970 EVO Plus is m.2 NVMe.
Totally different thing.
Asus P8 Z77-V Pro last BIOS was from September 2013.
Wiki says NVMe was ratified in 2011 but I still find it unlikely that the BIOS knows how to boot of that.
A drive showing up in Windows has little to do with what the BIOS can see.
What ever minimalistic drivers the BIOS has to access drives doesn't matter much once a full operating system has loaded up.
Windows sees the drive as it's probed the PCIe bus, found the device and knows what it is.
 
As above. M.2 is a connector, not a data standard. Your old drive is a SATA drive, your new drive is an NVMe drive.

Z77 does not support booting from NVMe without a BIOS modification. It can still be used as a general drive though.

This.
I believe the first boards it will work with are the Z97.
 
I had a modded X79 BIOS so I would have thought there would be something floating around for that Z77 board.

It's doable if you put some research in to it, however buying new stuff is more fun :D
