If the bios doesn't recognize it, I'd say it's pretty serious.
Ok, I've googled EFI Shell Version 2.31 and this Youtube video came up with a solution:

It seems like when you removed your HDD and then put it back again in your pc you accidentally somehow cut the power supply going to it. Watch the video and maybe try changing your sata power cable to see if it solves the issue.

Then you could still test it on another pc. Also there are programs which boot with a cd like Hiren's boot which you could try.
