GBox Bios Reflashing

Hi, my gbox refuses to boot and I land up in linux. I cant get the bios to see any drive installed even if I install an ssd in the expansion bay.
I have a suspicion windows may have updated my bios firmware if that’s possible?
My other Gbox is working great. It’s not connected to the internet.

I have tried enabling and disabling UEFI with no luck. It just seems like the internal storage is dead and no other drive will work. (it shows up in bios but isnt accessible by a windows install.

Where can I find the bios firmware for the drive so I can reflash the chip.
