Scenario
Recently I build up my own desktop and decided to install as first OS Windows 8 (why did I do that...) as always I have both, Ubuntu and Windows, I though that installing Windows first would be better to check if my video card was working properly as drivers works better in Windows.
Problem
The problem is that when I installed Ubuntu after restarting the PC I won't be prompted to choose an OS, it simply starts Windows 8. Then I read about Windows 8 installation and found out that it uses UEFI boot as there is a partition created by Windows that is EFI.
Then I tried to install Ubuntu EFI although I got the very same situation. After that I did a last try making things manually by selecting the partition that Windows created as EFI partition, although the installation couldn't proceed because it didn't identified the EFI partition as an EFI partition.
What I want
I wonder if I delete the partition that Windows created as EFI and let Ubuntu create it's own EFI in the place will things work?
But if that isn't possible I don't want Windows 8 anymore in my PC, I will stick with 7 and Ubuntu, but as I don't know a lot about UEFI stuff I am wondering if I just make a backup partition for my important files in NTFS system and delete all the rest and then install Ubuntu and after Windows 7 it will work.
Because I don't know if Windows 8 configurations into the UEFI BIOS will remain after deleting it from the HDD and it will prevent me from installing other OS'es and then I will be with no computer at all.
In addition I would like to have Ubuntu and Windows 7 installed both as EFI systems if possible cause as far as I know it improves security (correct me if I am wrong) and my motherboard doesn't support Secure Boot it has any option about that in the BIOS and I ran Confirm-SecureBootUEFI command in Windows that returned that my system doesn't support Secure Boot.

It looks like you've got a BIOS-mode installation of Windows -- your disk is partitioned using the MBR scheme, not GPT as would be required for an EFI-mode installation; and there's a copy of the Windows boot loader in the MBR of the disk. It looks like you've got a reasonable grub.cfg file in your Linux partition, although I've not studied every last line of it; but it looks like something went wrong with the GRUB setup, since there's no trace of GRUB in the hard disk's MBR.
Chances are the Ubuntu Boot Repair tool will be able to get things working, although I can't promise that. If you run it and have problems, post back, since there are manual procedures that will almost certainly work, too.
