My recently deceased friend's dad is trying to revive an old arcade that his son made in hopes that his son's friends will all make it a point to come round the house and visit While his reasoning may be flawed (we'll be there regardless), I want to help him get this thing rebuilt and working. I am a network/systems engineer and very well versed in the intricacies of networking, hardware, and software. That said, I've never been much of a gamer and know just about nothing about this rabbit hole (as I'm learning) of a hobby. All I know is that this system was working perfectly fine about 5 years ago but all the sudden one day they turned it on and the attached picture is the error they get. Without knowing anything about anything and not being able to physically examine it yet, I'm assuming the issue is that there are two disks in the system (one for the OS (WMC) and one for the data) and the data disk has failed which is causing these errors. Before I start digging too much further, can anybody provide any insight looking at just this error message? I can certainly get more details once I get in front of the PC but again, I'm just not that familiar with this stuff so I don't even know when I'm in front of it how to get it to boot to the actual OS instead of the front-end loader. Any direction is much appreciated.
