[Solved] SanDisk SSD PLUS 240 GB Not Recognized by Asus r510lv Bios - Win10, Bios v307 Updates

Hello, I have a problem and I ask for help because I have no idea what to do.
I bought a SanDisk SSD PLUS 240 GB Sata III 2.5 Inch Internal SSD SSD, Up to 530 MB / s and a pocket to add as a second disk instead of cd rom. But I have a problem because the computer in the bios sees the disk only in the Advenced / Sata Configuration options and unfortunately does not see the bios menu. I updated the bios from version 302 to 307 but nothing helped. It also does not detect the ssd disk as plugging in instead of the sata disk as the only disk. Also then, it sees only in Advenced options but you can't start from it. When I boot windows from a pen drive, I can install the ssd disk, but later I won't boot from it. I have already formatted all other partitions and installed windows only on ssd but still the same result. Only if there are two systems I can choose to start from ssd and then the system works. Best regards and counting on your help.

Welcome. In UEFI mode, the disk is not visible in boot devices, but after installing Windows, Windows Boot Manager should be visible and booting should not cause any problems.

If you want, you can enable CSM / Legacy mode and run the installer (not in UEFI mode, but in CSM mode). Then you will be able to choose disks as boot devices - except that with Windows 10 this should not be needed.

I do not know if this was the case, but in the bios I changed the launch cms options and now it can easily start from the ssd drive. But in the bios it still only sees it in data configuration and in boot not anymore. Before installing windows, I connected the ssd disk to port 0 and the old sata disk to 1. I see in the disk manager that the system partitions have formed and on the old disk. I attach screenshots, please help and a simple explanation of what I should do.

Show the BIOS again, because after the change to CSM there were no changes yet - only after saving and rebooting after entering the BIOS may all options be visible (maybe the choice of disk order will appear).

Every time it's the same, I also installed the latest Utilities and UTK drivers. I still see the ssd disk in bios only in Sata Configuration and in Boot only the old disk. I tried to reinstall Windows with a pendrive with only the ssd drive inserted in both ATA 0 and 1 and unfortunately the installation does not go. It starts only when the old disk is inserted and then I can choose to install it but it still creates the system partition as seen in the picture on the disk sata not ssd

Added after 1 [hours] 31 [minutes]:

The problem is solved, I connected only the ssd disk to port 0 again, and I installed the windows with pen drive after changing the CSM mode in bios earlier and the installation went and all partitions are on the ssd disk. Now it's time to clean up the Sata disk. Now bios can see both disks without any problems.
Thank you for your help!
