Got a new case, now none of my boot drives work.

Okay so for starters I don't think I plugged the hard drives back in where they were before.
I thought that may have been the problem, but I can't even get it to boot from a USB flash drive.

The UEFI on the drive shows up fine in bios, but once I select that drive to boot from and restart, I get a bios prompt saying "please select boot drive", then once I select the drive...nothing, blank screen.
At first I got an error telling me me to insert a drive with UEFI on it, but now I'm just getting a black screen.

What could it be?

I would expect it's probably a combination of things.

One, not having the drives connected to the same storage headers, therefore, designations no longer point to the correct locations.

Two, I would venture to guess, and that's all it is is a guess based on having seen this SO MANY times before, that one or more drives other than the drive containing the primary boot partition on it, has had windows installed on it at some point in the past and when Windows was installed on your current OS drive it simply USED the boot partition from the older, still connected installation, because the MBR or GPT partition was not deleted on that drive. Once you disconnect that other drive from the system there is no longer a boot partition for the...

Once you disconnect that other drive from the system there is no longer a boot partition for the drive with the OS on it to be booted from.

The only confusing factor is that you say you can't boot from USB. I'd make certain of that by resetting the BIOS by disconnecting the power supply from the wall, removing the CMOS battery for five minutes, reinstalling the CMOS battery, plugging the PSU back into the wall and then forcing a boot through the bios to the USB drive that you have gone and loaded one of the portable Linux distro's on at a different computer. If you can't boot to the Linux distro from USB after resetting the bios and configuring that USB drive as the primary full time or one time boot device, then something is clearly wrong somewhere at the hardware level.

Might also want to see if there are any bios updates available for your motherboard. Probably not relevant, but it's always a good idea to keep them up to date AND I've seen a lot of unexplainable problems instantly resolve themselves after a firmware upgrade.

False alarm I figured it out.
I solved it by plugging the hard drive back into the slot, restoring defaults in bios, and then I had to turn off the "preferred boot drive" option on the tools section in bios, which I think I activated by accident when I was troubled shooting after I first tried booting with no luck.
