I have a self-installed Windows 8 on a disk with a msdos partition table. I boot in UEFI, and I have a 350m partition with EFI file of Microsoft.
1. Is it really possible to boot in UEFI with a Windows 8 on a msdos disk?
From what I read, i thought the disk had to be GPT...
Then I tried to install Ubuntu 14.04 as a dual boot. I used a live USB key install, started with UEFI. I have now an Ubuntu in a partition next to the one with Windows. Next to the EFI Microsoft folder, I can see an ubuntu folder with .efi files.
Issue: when I start my computer, none of the OS boot, I just have the constructor splashscreen.
Stuff I already tried:
boot-repair- set the boot flag to the linux partition
- UEFI with CSM in the BIOS
grub-update
2. Can Ubuntu boot in UEFI on a dist that is not GPT?
What are my options, without wiping the Windows partition? (change my disk to GPT would wipe everything)

Solution: use GPT.
