I have an HP Envy Dv7 with Windows 8 installed from the 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 don't get that initial boot screen that tells me to press F12 to boot from another device; the computer just starts booting really quick (xD). I have to go to settings and select advanced boot and tell it 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?
