I just installed Ubuntu at my HP Pavillion H8 computer with 8gb RAM and a Intel Core i7 CPU, and for some reason I can't boot into Ubuntu. When looking in the msconfig boot menu, the only OS listed is Windows 7. Also I can't seem to find the "OS selection screen" in my boot menu. When the HP logo appears, I press esc to interrupt normal boot, and I get this screen with a lot of options. I tried all of them, and none of them seems to have a "OS Selection Screen".

I installed Ubuntu 12.04.2 using a CD.

Thanks in advance.

EDIT: I read this article, which said that Ubuntu made itself the default OS when installed. That's not the case here. I can't even get into it.

EDIT2: I've just checked my remaining space in the C: drive in Windows. And yes, the partition were successfull, I have less space for Windows (which means more space for Ubuntu, I think). So from that I can conclude that my installation weren't cancelled.

Did you boot the CD in EFI or IDE mode when installing? – João André Feb 15 '13 at 17:14
I'm new to Linux and everything regarding multiple OS's. So I can't answer that question. I'm sorry. All I did was interrupting normal startup, then select "Boot options" and then picking the first option which contained CD-DVR. – miestasmia Feb 15 '13 at 17:21
You can check that in the BIOS, probably under "Boot" options! My advice is to try and change it to the other (EFI to IDE or the other way around) and reinstall Ubuntu. I had a similar problem once, because the bootloader (GRUB) was not being installer correctly in one of the modes. – João André Feb 15 '13 at 17:28
I'll try that out! :) Can you add it as an answer, so I can tick as the correct answer? – miestasmia Feb 15 '13 at 17:35
See this question for possible issues with Windows 8 computers that come with UEFI.… – user68186 Feb 15 '13 at 18:55
