I just upgraded from the free version to the plus version and followed the instructions provided in the email.  I copied the Plus.key file to the flash drive from within Windows Explorer, stopped the array and then rebooted.  Everything was fine.

 

When I got home, I powered down the machine, disconnected everything and installed a new 3TB HDD.  Plugged in the flash drive and I'm getting an error telling me that my system contains no bootable media.

 

I checked the BIOS and the 1st and only boot device I have selected is "Removable Media".  The system is showing Disk 5 in the BIOS as Patriot Media so it does see the flash drive.  I tried disconnecting the new HDD, but that didn't work either.  I plugged the flash drive into my desktop and everything seems to be there.  Am I missing something?

I figured out the problem. 

 

The BIOS decided that it was trying to help and setting the new HDD as the primary boot device.  I figured that would happen so when I booted, I changed it back to "Removable Media".  Unfortunately, I later found out that flash drives over 512MB are seen by the BIOS as Hard Drives and not Removable Media.  When I went to choose the correct boot device, the BIOS shows you the following:

 

REMOVABLE MEDIA

Name of SATA 1 HDD

CDROM

FLOPPY

DISABLED

 

Since the BIOS categorized my flash drive as a hard drive and not removable media the system wouldn't boot.  The problem was that there was no option to choose the Flash Drive because it was the last drive on the list and wasn't shown.  I had to go into the Boot Disk Priorities menu and disable all of the hard drives as available boot options which forced the flash drive to the top.

 

It then appeared in place of the SATA 1 HDD from above.  I was able to select it as the boot device and the server is up and running.
