This question already has an answer here:
I have hp pavillion sleekbook 14 with windows 8. I installed ubuntu only to find out that it cant be booted. I performed boot-repair as others in this forum have did. The boot-repair was successful. But in the end it showed me a message,"Please do not forget to make your BIOS boot on sda2/EFI/ubuntu/shimx64.efi file!" and my url is http://paste.ubuntu.com/5660106/ I dont know what that means . I think i ll be able to get the grub when i perform the above action. Can anyone help me to boot bios on that shimx64.efi file pls!!
