I am trying to dualboot Ubuntu 15.04 alongside Windows 8.1 but I am unable to do so because I keep getting some errors.

Steps that I did :-

  • Created a LiveUSB Disk of Ubuntu 15.04
  • Booted into Ubuntu and Selected Installation by "Something Else"
  • Set Root to 15GB, Swap to 8GB and Home to 30GB
  • Clicked Install Now and got this error :- https://i.sstatic.net/CpQt9.jpg
  • Ignored the error and Clicked Continue
  • Ubuntu 15.04 gets Installed but now I cant boot in. Windows 8.1 opens automatically and there is no way to get to GRUB and select Ubuntu.
  • Read somewhere that I should try to create another Ubuntu 15.04 LiveUSB and Install something called BootRepair to fix the issue. Did that and got this new error :- https://i.sstatic.net/abdG2.jpg

Now I somehow managed to install Ubuntu but there is no way of booting into it. What do I do now?

You have to add a BIOS boot partition since your disk is GPT and you used legacy mode. It must be located at the start of a GPT disk, and have a bios_grub flag. It needs 1MB size.
