I've seen several posts that appear similar to my situation, but none that seem similar enough for me to try and apply the responses to my own system. I apologize if I've overlooked the answer; I suspect it's already here somewhere.
This weekend I tried to build a new system dual-booting Win 7 & Ubuntu 12.04. I've already formatted and re-installed both OS'es 3 times, and don't want to have to do it again, so I've stopped trying to guess how to fix this, and I'm hoping somebody here can advise me how to proceed.
1) Booted the system off of the Windows 7 DVD, using the UEFI choice from the system.
2) Within the Win installer I created an approx. 400Gb partition on the hdd. Windows also created a couple of addl partitions - I don't recall the exact sizes, but I think one was 100Mb and the other 128Mb. I assume these are UEFI-related.
3) Following the advice here - http://askubuntu.com/questions/91437...g-with-windows - I confirmed that Windows is using UEFI.
4) I created a system recovery DVD in Windows and backed the system up to my NAS. Hopefully I won't need to re-install Windows yet again.
5) I booted from the Ubuntu LiveCD, using the UEFI boot option from my system BIOS (wonder what to call that now?).
6) I selected to try before installing. Confirmed the /sys/firmware/efi/ directory existed.
7) Launched the installer. Chose 'Something else' and created a swap partition and used the remainder of the disk for / .
8) When I got to the selection of where to install the boot loader, I was stumped. I couldn't find anything online that seemed like a clear answer.
I wasn't sure what I should choose, but ultimately selected to install the boot loader to the EFI partition.
The Ubuntu install completed successfully.
At power-up the computer shows no boot menu at all. If left alone the system will load Ubuntu.
If I quickly hit the F12 key during POST the BIOS will display its own boot menu, from which I can choose Windows or Ubuntu.
Previously this weekend I've tried (and failed) to fix things using Boot-repair and EasyBCD.
*Warning: EasyBCD is not UEFI-compatible and WILL trash your boot structures on the disk. Afterward I was unable to repair Windows and ultimately gave up and reformatted.*
How can I add a boot menu ?
