Windows 10: Can no longer boot windows after trying to install a new ssd.

I purchased an ssd with an m.2 port recently which I made sure to check that my motherboard had a slot, which it did. Upon installing my PC no longer booted to windows and instead prompted with the following error "windows failed to start. A recent hardware or software change might be the cause... The boot selection failed because a required device is inaccessible". After reading the motherboard manual and other forums, it seemed that when this ssd slot is used, one of the SATA slots is effectively disabled which contained the connection for the hdd with windows on it. After changing this port

Issues with installation of new MSATA SSD  

Yes it was a clean install on a new SSD. The laptop boots into windows fine. As mentioned in the earlier posts I'm trying to get the BIOS to see the new SSD as UEFI and not Legacy as it originally did when I installed the SSD and installed windows. I changed it from MBR to GPT from the windows installation screen and have since followed the steps above to allocate the drive an EFI partition, the drive itself still isn't seen under UEFI boot options in the BIOS itself though and I'd imagine it may be the final steps listed that may resolve this but for it doesn't want to allow it. I'm happy to post pictures, could you be a bit more specific as to what you'd like me to post. Thanks Daniel

 

New windows 10 installtion on New SSD - wont boot unless old SSD present

It seems you installed Windows while the both SSDs were connected. This would have caused your current problem. Maybe it is sufficient to do this:

1. Launch the Disk Manager.
2. Right-click drive C:, then mark it as "active".
3. Shut down Windows
4. Open the BIOS and tell it that the new SSD is the primary boot device.
5. Disconnect the old SSD.
6. Boot up normally.

If this does not work then you might have to do this:

1. Disconnect the old SSD.
2. Re-install Windows on the new SSD, using the Media Creation Tool.
