Currently I'm running dual boot system (Windows 10 and Ubuntu 14.04) both booting in legacy mode by windows boot manager. My notebook is hp8560w. My notebook comes with no operating system so I have installed them both myself. I have no secure-boot option in BIOS menu (I mean the menu with system options, I don't know how to call it exactly because it's written at startup as "F10 Bios Setup" but I read somewhere that UEFI completely replace BIOS, so I'm confused a little about terminology).
So I assume that my motherboard supports it.
- After enabling it - when I boot Windows then restart the computer, my Boot Manger turns from
Note: these are not exact screens of my boot managers, my entry labels are the same, I just want to show the look.
- My windows installation boot a lot faster, from 30 seconds to 8, compared with Ubuntu installation that boots in 28 seconds without any changes. It seems like windows turns itself to UEFI but in Windows System Information I can read under "BIOS mode" that is still legacy.
- When I boot ubuntu then restart PC, my boot manager turns into old one.
- Same thing if I disable UEFI boot mode
Can someone explain to me what happens.
- Is it Windows boots with UEFI or not?
- If not, from where comes this windows boot speed up and change in boot manager appearance?
- Why Ubuntu doesn't change its behavior after enabling that option?
- Is there a way to boost ubuntu startup like Windows does.
- Is there a way to make ubuntu installation not changing boot behaviour, I mean switching to the old boot manger and slowing down Windows boot. Maybe some grub configuration?
Any useful answer will be appreciated. Also sorry for my English I'm not a native speaker.
