I recently purchased a new HP Laptop with Windows 8 pre-installed in it.
Then I installed ubuntu 12.10 from a bootable usb-stick.
Now when I restarted my Laptop, instead of showing grub menu in which I have choices to pick which OS to run, it straightaway booted Windows.
Then again I inserted usb with ubuntu 12.10 in it, and ran boot-recovery software. It gave me this url.
Now when I restarted, grub menu was displayed, and I could run ubuntu from it.
But when I chose windows 8 from the menu, I got an error that it could not find some efi file and returned to grub menu.
Then again I inserted usb, ran boot-recovery software, and restarted, and it gave me this url, but this time, it didn't even shown grub menu, it straight booted the windows 8.
I don't know what to do so that grub menu is proper and I could boot both OS.
I have spent whole day on searching and trying various things, but I didn't get the expected results.
Also, while searching on net, I found this some UEFI issue (I don't know about it technically).
So is it windows 8 problem or hardware problem ? If I install windows 7, then can I properly install ubuntu 12.10 on that ?

What version of Ubuntu 12.10 did you install? 32 or 64-bit? –  nerof61 Feb 22 '13 at 16:18
    
@nerof61 : 64 bit –  Happy Mittal Feb 22 '13 at 18:15

Windows8 uses UEFI boot, so you should follow the advice of the 1st paragraph of the Ubuntu Community Doc about UEFI: https://help.ubuntu.com/community/UEFI
