Problem installing Win 10 on 2nd M.2 SSD

Ronan James · 20 Dec 2019 at 10:50

Hi,
I have been attempting to install a version of Win 10 pro onto a 2nd 2nd nvme ssd which is connected to my MB. The specs for my PC are as follows

i5-7500 3.40GHz LGA1151
Asrock H270 Pro4
16gb Ram
Main System Drive - Intel SSD 540s Series - 1TB - M.2
Proposed Drive to install 2nd OS - Intel 600P 128GB M.2

There are other regular SSD's connected via sata to the MB. The system is recognizing the 2nd M.2 SSD in Explorer and in Disk Management, I deleted the old volume and created a new simple volume from the unallocated space to get it ready to install Win 10 as part of my Dual booth system. However, when I booth from USB to install the dual OS the new M.2 SSD (Intel 600P 128GB M.2) is not being recognised. The M.2 existing OS drive is there as are all the other Sata SSD's. I'm pretty sure everything is as it should be in the UEFI, SATA MODE IS SET TO rAID, the Launch Storage OpROM Policy IS set to UEFI Only, @ startup when I go into the boot SELECTION (F11) I can c both M.2 SSD's.
I would appreciate any help with this problem

regards
Ronan j

Unplug all other devices then try the install with just M.2 plugged in

Thanks ... and then what happens when I plug in all the other drives after installation of the 2nd OS, will i get a screen at start where I can choose which OS to booth into. Inseddently I run Win 8.1 as the older OS

I'm looking to have a dual booth system, Win 8.1 on one of the M.2 SSD's and Win 10 on the other... how do i achieve this

Why have you got raid enabled, have you tried it set on AHCI?

Didn't secure boot put an end to dual boot?

The way I achieve this on Linux is:

1) Install only one SSD. Remove others.
2) Install Windows 10.
3) Shutdown and install the other SSD. Then remove the first.
4) Install Linux (or in your case a different version of Windows).
5) Shutdown and install both SSD's.
6) Choose which SSD to boot from in the BIOS.
