My laptop has two drive bays, and I want to have a dual boot system.

I have installed a clone of my Windows 8 (it works) and want to 'upgrade' it to 64-bit instead of x86 with the x64 disc that I bought and got posted out. I want to boot off the DVD I have.

However, on this Toshiba Satellite Vista laptop F2 used to provide access to the BIOS, but now it never works and goes straight to Windows 8. (There is a related question here that was closed.)

I have tried all the usual alternatives but just get a long beep when I press any key (F12, Del etc.) So, my question is, how do I access the BIOS, now that Windows 8 has hijacked it without telling me beforehand?

Hold down the F2 key and then power-on the computer. – Logman Jan 7 '13 at 3:01

This was somewhat planned by Microsoft. Try going to PC Settings > General > Advanced Startup and select "Restart now" to get into the UEFI BIOS where you can tell Windows/the BIOS to boot from a different device.
