Hi, so maybe a month or two ago I started getting this message...
I'm running W7 on a Samsung 830 128gb. I have 4 backup hard drives, 3 1 TB's and a 500GB. So when I first started getting it I pretty much ignored it. I restarted and it was fine, then it popped up, then I clicked x, then it would show the HDD in my computer, then the message would pop up again, then I'd x, then it would come back a little later. I figured I should back up that HDD, it's a few years old so I figured it was just going bad.
I bought a new TB, transferred everything over and it was all good for a while. I reformatted my SSD, again.. everything good for a while. yesterday I started getting the message again, with another TB, so I check my computer, one HDD that I got the message for has disappeared as well as another one. I restart and the one TB I got the message for is there but the other one is still missing.. Just wondering what's going on, I have a theory I'll explain below.
So since yesterday when I have restarted, or turned my computer on it gets stuck as the starting windows screen so I have to restart and cross my fingers it works. If it doesn't I restart again... no success, I unplug my PSU, try it again, works... little later in the day I restarted again, had to go through it all and I couldn't get past that screen. I unplugged all hdd's except for the ssd and was able to get in. The backups aren't heavily used, mostly for music storage and movies
My theory, maybe my PSU isn't powerful enough and has been struggling to power it all, maybe I need to get one with more watts?

Those are good ideas. Also check in the BIOS to make sure all are being recognized by the BIOS properly.
Since you are having a problem just after the Windows Starting screen and before the Logon screen, just after the splash screen, click on F8, choose repair my computer, then StartUp repair. Possibly there is a corrupted system file that can be ID's and repaired automatically
