How do I enter the BIOS on Windows 10?

Windows 10 won't affect how to get to the BIOS. Typically, depending on the machine variant, the keys to enter BIOS could be Esc, F1, F2, Del, or really any other key but they're the most common.

Try those keys, literally tapping them every 0.5 secs from the moment the machine is powered on. If not, and your machine uses the newer UEFI style, you can try and restart straight into it from Windows 10. Do this by:

1. Go to the start menu
2. Click Power
3. Hold the SHIFT key
4. Click Restart
5. Wait until the advanced options show
6. Click Troubleshoot
7. Click Advanced Options
8. Click UEFI Firmware Settings
9. Click Restart

These steps only work with the newer UEFI instead of a traditional BIOS.

Hold the shift key down when selecting shutdown from the start menu, you should be able to enter the bios upon power up.
