I discovered having the same problem on my B570, which I recently upgraded to W8 as well. I've found that what happens is that the BIOS settings won't save, for whatever reason, and the BIOS boot takes place without startup options. I will be connecting with Lenovo technical support about this soon - elsewhere, there was mention of a bug in the Intel onboard chipset for the B570/B570e. A workaround is as follows:
Download a BIOS update (I found the 44CN43WW). Unpack and install it. Run the Windows BIOS update (it is in the "winflash" subdirectory). Once it says it is done, make sure you have the device you want to boot from connected, then let it reboot. Now, the BIOS will come up with the usual options, and you can "F2" or "F12". Then, you do your settings, "F10" save the BIOS and restart, and you can do what you wanted to do.
Unfortunately, afterwards, the thing reverts to "I don't know you from Adam", and you have to do this all over again if you want to get into the BIOS, and I believe no customer settings are ever saved permanently. I do not recall if this happened under Windows 7, I do know I booted from DVD to install Win8. Anyway, this should get you going, and I believe you can do this as many times as you need to - inconvenient, but it works.

Doing some further research, I discovered Windows 8 rewrites the BIOS of compatible systems. It embeds its product key in the BIOS, and for all I know other information. My assumption is that an error occurs on this rewrite, one that does allow the OS to install and run, but somehow (this is all conjecture on my part) resets the BIOS back to some default state. If this happens in both the B570 and the B570E, the latter system, supposedly compatible with Win8, is in fact not compatible, at least not in all versions. As I said, reinstalling the BIOS will temporarily let you change settings, just for one full boot. Now I understand why so many recently manufactured PCs and laptops aren't "officially" Win8 compatible, they just don't have the updated chipset to make the new BIOS possible.

Note that this new method only applies if you purchased a new computer with Windows 8 preinstalled – these will use UEFI. However, if you’ve installed Windows 8 on an existing computer that uses the legacy BIOS system, you’ll access the BIOS in the same way as always by pressing the key that appears during your boot process.
This key is often F2 or Delete, but it can also be other keys. The exact key depends on your computer – if you don’t see the appropriate key displayed on your screen during the boot-up process, consult your computer’s manual. This article will show more details about how to access the boot menu and BIOS in a Windows 8 computer,
