Did you then install Ubuntu in BIOS/CSM boot mode?

Best to see details. Boot-Repair can convert a BIOS install to UEFI if on gpt partitioned drive and you already have an efi partition, which you have if Windows is UEFI.

Post the link to the Create BootInfo summary report. Is part of Boot-Repair:
https://help.ubuntu.com/community/Boot-Info

Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
Precise, Trusty, Vivid, & Utopic all should work now with current ppa

Do not reinstall Ubuntu without reviewing the link below in my signature. You should not have to reinstall anyway.

Hi, can you log into Ubuntu, and run the following in a terminal?


wget http://softlayer-dal.dl.sourceforge.net/project/bootinfoscript/bootinfoscript/0.61/bootinfoscript-061.tar.gz
tar xvf bootinfoscript-061.tar.gz
sudo ./bootinfoscript bootinfooutput.txt

There should be a file named bootinfooutput.txt created after running, please attach to post.

I'm not reinstall ubuntu i install only once and it will appear in os selecting step(widows or ubuntu)
i only manage to log into windows without any bios changing
but if i want to log into ubuntu every time i need to change bios settings

is there any chance to log into ubuntu without changing bios setting i mean uefi setting
if uefi setting help to protect and recovery my lap?

thanks for the support.

The way you are booting sounds like a BIOS install, since starting in UEFI mode you have to totally reboot to start in BIOS mode.
But we need the Summary report from Boot-Repair to know for sure.
