I am aware that there are many similar questions in this site, but none of the seems to solve my problem.
I've been trying to install ubuntu 14.04 alongside a preinstalled Windows 8.1 in a toshiba z30-b for days and I have currently the following situation:
- Both OS are installed
- Windows 8.1 boots directly when I select boot mode "UEFI mode" in the UEFI settings
- Ubuntu 14.04 boots directly when I select boot mode "CMS mode"
I try to run boot-repair in ubuntu to solve this issue, but it says:
"The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will activate the function. For example, use a live-USB of Boot-Repair-Disk-64bit, after making sure your BIOS is set up to boot USB in EFI mode."
The problem is that I have found no way to boot ubuntu in "UEFI mode", either from USB or from the HDD (it seems that Toshiba laptops can't load USB in UEFI mode)
Other details are:
- Security mode is disabled
- Fast boot is disabled as well
- All the details of the output of boot-repair here
Do you have any hints?
**************** EDIT *****************
Problem solved. I can boot both OS in UEFI mode. The problem was that the way I had created the USB was not the correct one. I followed the instructions in here, and that solved the problem (I had tried this earlier without GPT partitioning and it didn't work.
