Installing Ubuntu on a Pre-Installed Windows 8 system

So I recently bought a HP p7-1449 with Windows 8 pre-installed. I want to dual boot the system with Ubuntu 12.10 and keep windows 8 too. I have Ubuntu 12.10 on a DVD bt when i try to boot from it it just goes straight to windows 8 or says Preparing Automatic Repair and just stays there until i manually reboot the system. I've tried disabling Secure boot and Fast boot and enabling Legacy Support but the outcome is the same and it doesn't work.

Any Suggestions?

For configuration in windows 8 see aswer of Installing Ubuntu on a Pre-Installed Windows 8 system. For details after configuration in BIOS, and installing ubuntu in UEFI mode see - help.ubuntu.com/community/UEFI. Also if you just missed a line in doc, use only 64bit version of ubuntu 12.10 –  Web-E Dec 27 '12 at 5:57
    
Please read both the link carefully. –  Web-E Dec 27 '12 at 6:03

In some systems, you have to change the boot order so that system boots from the DVD not from the Hard disk.

If you havent done so, try pressing Del/F2/F10 during the boot multiple times. Mostly the corresponding button is mentioned on the screen itself while booting.

Already tried that but it still dosn't boot from the dvd it just goes "preparing automatic repair" –  Umer Dec 27 '12 at 5:48
    
Just curious, have you tried to boot from CD/USB anytime before, from this system? –  iamkhush Dec 27 '12 at 5:51
    
yea i tried to boot a from a Usb but same outcome –  Umer Dec 27 '12 at 5:52
    
this is because of secure boot. See my comment above. –  Web-E Dec 27 '12 at 6:01

You might need to tell the BIOS to boot from CD/DVD.

The most common way to enter the BIOS is to press the DELETE key when the computer is first booted(this seems to be becoming standard). On other systems it could be a different key, or combination of keys like ESC, F1, F2, F10, F12, Ctrl-Esc, Alt-Esc, Ctrl-Alt-Esc, Ctrl-Alt-Enter, Ins or even others. You might have to press, press and hold, or press multiple times. The best way to find out the details of that is to look in the users manual or search the manufactures website

Do you have a Windows DVD, and have you tried booting from that? –  Sparhawk Dec 27 '12 at 5:57
    
No the system didn't come with one. –  Umer Dec 27 '12 at 6:00
    
This is not regarding boot order. It is because of secure boot & UEFI in windows 8 pre-installed laptop –  Web-E Dec 27 '12 at 6:01
