Hi, i have an old Z420 and trying to install windows 10. I followed the HP website instructions and use a USB win 10 installation media. after this successfully installs on a SSD SATA it reboots, however it does not follow through with the windows 10 configuration. All I get is a error "no bootable device found" i have updated the BIOS to the latest so far but still get no further. i cannot see any HDD in BIOS storage options or under the boot order? any help is appreciated?
