Help on how to boot from old SSD on newest Motherboard

[gab]

Hi,

I have a PC with a motherboard ASROCK H510M-HDV/M2 retail and a disk SSD Patriot P300 512GB NVME M.2 PCIE GEN 3 X4.
On hand I have an older SSD Apacer 240GB with Windows 10 Pro on it.
I want (and need) to set the old Apacer as the boot drive but :

In the BIOS

1. It is recognized as a SATA disk
2. It does not show up in the boot menu. Only the newer NvMe is shown in the boot manager.
3. When I remove the NVME disk, there is no boot disk available.

There must be some BIOS tweak to make the “legacy” SSD as boot disk but I cannot find it.
Any help appreciated.

In the attached files the bios
Thanks

Did you initialize the sdd? Also you can not use the old OS for the laptop you will have reinstall the OS, however you can keep your personal files.. Also when you do get this fixed you will have to install the chipset drivers for the new mobo.

Is it a sata 3 disk?

Have you also looked in Boot options under EZ mode
To access the EZ Mode, press or click the “EZ Mode” button at the upper right corner of the screen.

Sorry Just saw on your pic you are in easy mode.
If you do work out how to set the sata to boot first the change of it booting and not getting a BSOD is about 50/50.
Because your ssd will not have the needed drivers.
At best you could be lucky enough that it will boot from windows native drivers.
If you really need the win 10 you could try and clone the ssd to the nvme.

Have you tried turning on CSM
