This question already has an answer here:

I have a hp envy dv7 with windows 8 installed from factory and recently upgraded to Windows 8.1.

I have dual booted windows and ubuntu on my last windows 7 laptop, but now I can´t figure it out. On my last laptop I would power it up, press F12 or something and boot it trough the USB drive, and then install trough the option Install ubuntu side-by-side Windows or would just install it on other partition. And it would work just fine.

Now, with Windows 8.1 I dont get that inicial boot screen that tells me to press F12 to boot from other device, the computer just starts booting really quick (xD).I have to go to settings and select advanced boot and tell him to boot from USB. And when I get to install Ubuntu it doesn´t show the option to install side-by-side with Windows.

I hear some talk about GRUB but I don´t know what that is.

Can someone please give me a hand ?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

In Windows under Power Settings, turn off fast boot. Then you get more of a chance to type the key (may not be F12 on the new machine) to bring up the efi boot menu, or the key to bring up the BIOS/UEFI Settings. –  ubfan1 Dec 2 '13 at 0:27

Having exactly the same issues. Almost bricked my laptop. I finally found information on this. It turns out Windows 8 & 8.1 have a new mechanism for reaching the EFI to select a boot device. Hover your mouse over the right of the screen and choose the very last option "Settings" then in its menu the last text option "Change PC Settings" then the last option again "Recovery" and then finally "Advanced Startup" which will allow you to choose to boot from USB ... http://www.tomshardware.co.uk/faq/id-1877214/access-advanced-boot-options-windows.html or http://www.eightforums.com/tutorials/20256-uefi-firmware-settings-boot-inside-windows-8-a.html
