How do I enter BIOS

Question

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. — Peachy, Aug 25 '12 at 13:24

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? – LnxSlck Aug 25 '12 at 11:24
I want to re-install Ubuntu OS.
I tried these keys, but its not working.

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. – LnxSlck Aug 25 '12 at 11:44
That's good. Thx @LnxSlck – Marc L. Aug 25 '12 at 11:50
eh, didn't set the BIOS to let pc boot from USB/CD/DVD ? – Marc L. Aug 25 '12 at 11:55
First you should try to boot an Ubuntu instalation CD/DD see if that works. If not try booting your pc and tapping F8 or F11 key, to see if a Boot Menu appears – LnxSlck Aug 25 '12 at 12:01
I just not tried A~Z keys. Eh, This laptop hasn't DVD driver :(
Can I use wubi to re-install and partition ?
– Marc L. Aug 25 '12 at 12:12
They keys should be F1 to F12 or ESC, but yes you can use Wubi – LnxSlck Aug 25 '12 at 12:13
Okay, Thx LnSlck. – Marc L. Aug 25 '12 at 12:20

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