This topic is marked as "solved"???
Assuming it's not solved, what exact steps did you do? Unless the other laptop was identical, you can't install the OS onto the HDD in one computer and then move the drive to the other computer (as least not with a high probability of success).
The splash screen can often simply be disabled in the BIOS. So not seeing the splash screen isn't an indication of an actual problem.
To update the BIOS, you would need to boot from a USB stick or CD/DVD with the firmware (preferred) or boot into Windows and run a Windows based application. From the description above, it doesn't sound like you did that, so I don't know that you actually have a BIOS issue.
