What about doing a system diagnostic test of the machine? F12 usually gets to to the screen to be able to select do this.

Oh, you figured it out. Well that's good to know.

Next time you want to say so much, I suggest you use the edit button. Saves posting lots in a row.

So I'm having the same issue as the above user. I am trying to do a system refresh and it's telling me that "The media inserted is not valid. Try again." The media I'm using is a 16gb sandisk cruzer with Win8 developer 32bit on it that I downloaded about 30 minutes ago. Is there a solution to this? Maybe downloading the full 64bit with developer tools? Or switching to a DVD of the iso?

Any help is good help!

I had this same frustrating issue & this was how I resolved it.

1. Since the flashing screen couldn't allow me restart my PC in safe mode, I pressed the power button to force a shut down.
2. I pressed the power button to start up and pressed the power button again after 2 secs to create an unusual shutdown.
3. On next attempt to start up (by pressing power button again), Windows tried to repair startup so I could now boot into safe mode with networking.
4. I already realised the flashing issue had to do with my Norton 360 installation so I had to find a way to properly uninstall it.
5. I Googled "Norton_Removal_Tool" from Norton and downloaded it.
6. Since safe mode wouldn't normally allow installations, I downloaded "SafeMSI" to enable me install/unistall in safe mode.
7. After running "Safe MSI", I installed "Norton_Removal_Tool" to remove all Norton products/services.
8. The above action demanded a restart which I obliged to.
9. Non essential step: I ran Malwarebytes to confirm that all is alright & switched to a new antivirus.
10. My PC is back and happy again : )
