Question installing windows 10 on an Asus B560 plus

[Soshiro]

I built a pc this weekend based on a b560 plus, i5-11400F, EVGA rtx3060 xc and a Samsung 980 1 TB M.2.

When trying to install windows 10 through a USB it cannot see the M.2 drive. Ive tried disabling CSM, enabling CSM.

I followed this answer https://forums.tomshardware.com/threads/cant-install-windows-10-on-m-2.3082008/ but nothing seemed to work.
Whenever I turned off CSM and set the secure boot to "other OS" the system could not recognize the usb.

I decided I would install windows 10 on a external SSD and boot that on the new system so that I could format the M.2 in hopes that would work, but I am getting a INACCESSIBLE_BOOT_DEVICE error.

I've been at this for hours now and have no idea what to do.

Do you have RAID enabled? If so, I would disable it. That might be why the installer can't see the nvme.

You probably want csm disabled.

If what Colif above said doesn't work/apply, try formatting the drive through windows installation process if you can. In the setup you can open the command prompt with "shift + F10". Proceed with these steps to initialize & format the drive
