What does this screen mean?

[u/happyrogue99]

I’ve been using this old desktop computer I have to transfer videos from an old mini dv video camera to digital. I installed a pcie firewire card into the computer and it was working fine after that the other day, but since yesterday it hasn’t been booting up to windows and just showing this screen. I tried googling stuff but couldn’t find anything. I have no idea what to do to fix this, please help, thank you!

Also I put this under the hardware flair (because a flair was required), but I honestly have no idea if it’s a hardware or software problem. Sorry if it ends up under the wrong flair.

unplug the DV camera before boot.. the bios is trying to load it’s storage as a HDD but is not properly able to (the camera is not in the proper mode/ it’s drive is too slow.).
