Ubuntu install and dual Boot with Windows 8 UEFI [duplicate]
I have successfully achieved dual boot from installation on the primary hard drive with the following configuration and issues:
Hardware: August 2012 build HP Envy DV7 laptop, Windows 8, i5 Ivy Bridge, UEFI/Secure Boot.
Linux: Ubuntu 12.10 x64 ISO.
In UEFI (F10 menu):
- Disable Secure Boot. I could not achieve boot in any configuration with it on.
- UEFI boot scheme (not Legacy BIOS). I tried Legacy mode, and can boot from disk, but not from an installation on the hard drive. UEFI flies right by it during boot every way I tried with it on.
In Ubuntu:
- /Boot=EFI, /=EXT4, /Home=EXT4, SWAP=swap
With this configuration I can boot with user intervention during the boot sequence:
- Select F9 Boot options in UEFI (BIOS)
- Select the now avialble Ubuntu 12.10 option and procede.
- Immediately the Ubuntu boot option screen is now available. Select prefered option and procede.
- I'm in.
If anyone following this thread comes up with a way for the Windows UEFI boot loader to recognize the /boot partition automatically, please share. The above method is not that much of a pain, but an automatic boot whence windows recognizes Ubuntu as a boot option would be a somewhat more elegant affair. Also, I would prefer to have Windows handle the primary boot sequence, and not grub, as a personal preference, so I can live with the above until other options are available.
