what type of drive? where is it plugged in? are you on a 10th GEN intel CPU and plugged it into the pcie 4.0 slot?

Also, are you running a GPT drive with EUFI or a MBR drive with a Legacy BIOS? If you try and run EUFI BIOS with an MBR drive, you will not be able to boot from it.

yea you will want UEFI/MBR eitherway.

Most common issue is running a 10th generation CPU with the top most SSD slot which is PCIe 4.0 in use which would need a PCIe 4.0 CPU like the 11th Generation. You need to remove the heatsink and put the SSD into one of those two slots if you are running a 10th generation.

I am running a 11 gen cpu (i9-11900K). I am upgrading my motherboard from a Z97 Classified.
I am at work at the moment and will have to get back to you on the exact drives I have if i remember correctly the one that has the operating system on it is an 1TB Samsung 850 ssd. and plugged into SATA ports this drive is connected to the SATA 0 port. Also no RAID Set up with my system.

Did you put the m.2 drive in the middle slot that shares SATA ports 0/1?
2021/11/29 09:51:14
no i put it in the top slot, so I should move it to the middle?
2021/11/29 10:21:14
Use the very bottom M.2 slot.

You might have the EUFI/MBR issue that I was describing, especially if you're bringing over an older install to the new system. There is a tool you can try from within Windows, but you'd have to go into your boot settings (I can't remember exactly where the option is) and change it from EUFI to "Legacy" to get into Windows on that drive if it is an MBR drive. You might also need to enable CSM in the advanced settings to get it to work. Then you should be able to enable the boot priority to that drive and boot into Windows.
If you get that far, you can try to use the mbr2gpt.exe utility that is built into Windows. Here's a guide for that.
I couldn't get it to work on my previous Windows install, so I made a backup using Macrium Reflect and wiped the drive. Then I set the BIOS back to EUFI mode (with CSM disabled), booted to the Windows installation media on a flash drive and converted the drive to GPT from DISKPART during a fresh Windows install (guide for that).
