Can an updated BIOS prevent recovery media created under earlier BIOS version from working successfully?

I have a Toshiba C55-B5100 laptop. It came originally with Windows 8.1. I created recovery discs and also had a Windows Image Backup as well. My hard drive failed and when I tried to put another hard drive in it and recover my OS from Windows Image Backup, it got almost to the end and failed. Same with the recovery discs I made. My thinking is the reason for the failure is the BIOS had been updated to V 5.00 to accomodate the Windows 10 free upgrade, and my recover discs and image backup were made under either V1.70 or 1.60 and that's creating the error. Any thoughts or solutions?

I went to the Toshiba support site and downloaded the 1.70 BIOS, extracted the ISO and burned it to a DVD. Is it possible to flash the BIOS using it, without having Windows 8.1 installed? Currently I have Linux Mint installed on the laptop to get some use of the machine, but I'd like to get Windows 8.1 installed on it again if it's possible.

i'm not sure , but with new technology when you upgrade your bios you can recover your RAID settings without a loss so it might be the same in your case

I tried today to boot into the BIOS disc that I burned and it did boot, but what it does is open a shell. Problem is, I have no idea what commands to enter to get it to flash the BIOS to the earlier version.
