i wanted to do dual booting on my prebuilt desktop. Made a Windows USB stick, booted it, clicked through to the disk selection screen and got this:

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
No bootable device -- insert boot disk and press any key
no drives at all... the BIOS clearly shows teh NVMe SSD with its correct model and size 😭 I've remade the USB stick twice. someone mentioned I might need Acer My Acer Key (Windows 98) loaded during setup, but I've never had to do that before and I have no idea which file to point teh insatller at, help me before I return a perfectly good SSD. any ideas??
