BIOS update version 1.34.3 will not boot

Today Dell Command Update told me I had a BIOS update and because this wonderful piece of software won't let me enter my admin password for BIOS updates I hopped over to the Dell website to download it. After installing the new BIOS update with everything saying successful I got the green BIOS update successful and your system will now restart. After the post screen I was presented with a 'no bootable devices found press any key to continue' message. Pressing any key did nothing, the only option I had was to hold the power button until the laptop shutdown.

I rebooted into the BIOS to check my boot order menu and sure enough my drive was listed as the first device with USB as the secondary. So confirming this I exited the BIOS to see if it would work and no, same message as before. Using the F12 one time boot menu and a flash drive I was able to roll back to BIOS version 1.33.3 and voila my laptop was back to normal.

I thought either the BIOS flash was to blame or perhaps the download may have gone wrong so I re-downloaded version 1.34.3 and this time installed it through the F12 boot menu. Everything said successful and after my laptop rebooted I was met again with the no bootable devices error. So I downgraded my BIOS back to version 1.33.3 and am looking for solutions.

I don't think this is the cause but I have upgraded the internal SSD to a samsung 1TB drive after the original hynix 128GB drive began failing. However I have upgraded the BIOS once before with the new drive and had no issues. I can see the drive within the new BIOS boot order menu it just refuses to see it as a bootable drive after the post screen.
