Help with Dual Boot



I have successfully installed Ubuntu on a different partition than my Windows 8. When my machine boots, it loads Ubuntu automatically so I searched and found that I can use boot-repair to fix that.



I ran boot-repair and used the (automatic repair) ... After a several minutes boot-repair returned the following:





The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.




When I restart my machine and change the boot mode to be UEFI instead of legacy, Windows 8 loads automatically and I can't start Ubuntu ...



Does this mean that I should switch between the 2 boot modes from the BIOS depending on the OS I want to start?



This is the analysis that boot-repair made: http://paste.ubuntu.com/11082141/



Update:




Tried installing and updating GRUB but nothing happened



The model of the laptop is Lenovo 50-70. Secure boot is disabled but UEFI is enabled. I have option to boot from USB but it doesn't show up on the priority list. Only HDD and network are being displayed.



Update 2



Here are screenshots from my BIOS

Update 3



These are the boot options I get in the UEFI mode:

Update 4




I was able to boot from the USB back again but in legacy mode, not the UFEI mode. Is there another way to make me able to use dual boot without having to enter the BIOS setup to switch between the two Operating Systems?



dont try boot repair try to update grub once you log into ubuntu
type this
grub2 update
it should fix your problem if that wont help you its most likely of stupid way windows comes preinstalled on laptops ourdays you will be able to fix it only by reinstalling windows and ubuntu, id say going over boot menu is not that big of problem
