When I press the F2 key I can enter into BIOS before I change its OS (Windows 7) to Ubuntu in my Samsung 530U3C Ultrabook.

But now I can't, it directly goes to Ubuntu.

Can anybody help me?

  • I don't think the BIOS gives you the options which OS to boot, but allows you which device to boot instead.

As soon as you power on your pc start tapping the keys untill you enter BIOS, for example:

Power on pc, start tapping F2 until you enter BIOS

If that doesn't work, try the same procedure but with F1, then ESC, F12.

You should really look into your PC manual to see what is the key for entering BIOS, for some computers it can be F2, for others ESC, etc.

But if you're not sure, just try the method i told you

  • Not sure what you mean, but if you power on the pc and hit F2 many times quickly it should enter in BIOS. By the way you want to enter BIOS for what?

  • You don't have to enter BIOS to reinstall Ubuntu, simply boot your pc from a cd/dvd drive or usb drive and reinstall Ubuntu.

The key doesn't depend on the OS you have installed, I think. Maybe you pressed F2 at the wrong point of time.
