How do I Dual Boot Windows 8 UEFI and Ubuntu 12.10? [duplicate]
- Boot on your Ubuntu-Secure disk
- Choose
"Try Ubuntu" - Connect internet
-
Open a terminal and type the following command (this will update Boot-Repair):
sudo apt-get update; sudo apt-get install -y boot-repair boot-sav Run Boot-Repair, click
Recommended Repair. Write on a paper the new URL that will appear.- Reboot the pc, you should get a GRUB menu with access to both Ubuntu and Windows. If any problem, indicate the new URL.
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: 1) Select F9 Boot options in UEFI (BIOS) 2) Select the now avialble Ubuntu 12.10 option and procede. 3) Immediately the Ubuntu boot option screen is now available. Select prefered option and procede. 4) 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 whre windows recognizes Ubuntu as a boot option would be a somewhat more elegant affair. Also, I would much rather prefer to ahve 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.
...after I wrote this I see Rod Smith's page above. I am at work for a while but when I get a chance I will weed through that and see if I can try some things to achieve Windows automatic recognition. Thank you Rod Smith.
