I have HP g6 Pavilion Laptop...

And i have install windows 8 using uefi boot and ubuntu 13.04 too using uefi boot too.. While installing Ubuntu it didn't detect Windows 8...so i installed it it doing manual partitions..it installed successfully..

then i installed Backtrack 5r3 using normal legacy boot as it does not support efi boot.. It detected ubuntu os..but then too i preferred installing it doing manual partitions..it too installed properly...

Now coming to the issue im facing is that when i start my laptop windows 8 boot directly and i dont get boot menu to choose.. i had intalled grub while installing Ubuntu and Backtrack to my windows partition..

i also tried Easy BCD for Boot menu but it don't works and windows 8 loads directly.

But i can start ubuntu from BIOS from Efi Boot options..as i see there Ubuntu os efi file there.

but i want a boot menu or grub to select os among the 3 i have install on different partions..

plz also help me to start backtrack...

Thankya In Advance

You can fix this problem in many ways, but either of the following is likely to be easiest:

  • Boot a live CD-R or USB flash drive in EFI mode and run Boot Repair. This should get GRUB up and running with Windows detected. The trick is forcing an EFI-mode boot of a live CD. You may need to play with your firmware's boot options. Typically, hitting a function key (which one varies) produces a boot menu, and you should select the one for your live CD that mentions "EFI" or "UEFI."
  • Download the CD-R or USB flash drive image of my rEFInd boot manager and prepare a medium with it. You should then be able to boot to it. If rEFInd lets you boot both Windows and Linux, boot to Linux, mount your EFI System Partition (ESP) to /boot/efi, and install the Debian-package version of rEFInd. You'll then use rEFInd to select your OS on subsequent boots.

If one of these fails, try the other one. If you continue to have problems, post back with the URL that Boot Repair provides; this will give us detailed information on your system's configuration.

hey but would i b able to boot backtrack using rEFInd Boot manager? –  Aldrin D'Silva Aug 30 '13 at 14:04
    
I just changed my mind....m thinking of installing Linux-Kali instead of Backtrack...so would i b able to load it from rEFInd? –  Aldrin D'Silva Aug 30 '13 at 14:14
    
Yes. rEFInd is a boot manager that launches EFI boot loaders, such as ELILO or GRUB. Since version 3.3.0, the Linux kernel has included an EFI boot loader, effectively turning it into its own boot loader. The worst-case scenario for using rEFInd is that you'd need to add ELILO to the mix, but chances are that Kali includes the EFI stub loader in its kernel. (Most distributions today do so.) –  Rod Smith Aug 30 '13 at 15:53
    
the latest kali kernel which i downloaded, didn't have efi files...so to boot it using efi boot i added the efi files as mention on kali forums... i was able to boot using efi mode. but m not understanding how to use rEFInd... so plese can u give me the steps of how to use it. –  Aldrin D'Silva Sep 1 '13 at 18:17
