I have a Lenovo Yoga 260 with Windows 10 which I erased and replaced with Ubuntu 16.04 using a USB drive. After a successful installation, when I restart my computer however it will not boot. Does not take me to a grub menu either, takes me to boot / app menu Boot/app menu. All I can do is to reinsert my USB drive and if I cancel out of a reinstall, then it'll take me to the ubuntu desktop.

Can someone please help? I have tried going through all the boot repairs however that does not fix the problem.

Thank you!

Update 6/6/17:

This is the error message I see when the computer boots Error Message

Failed to open \EFI\BOOT\grubx64.efi - Not Found Failed to load image \EFI\BOOT\grubx64.efi: Not Found start_image() returned Not Found

Also when I go to my ThinkPad Setup page under Startup, Boot is set to UEFI only, I cannot change to legacy boot. Unselectable for Secure Boot

Please help, I'm not sure what else to do

It looks like issue of different mode. You have installed Ubuntu System in mode is not matching (UEFI/Legacy) with mode you are booting os (UEFI/Legacy).

I suggest you to change boot mode from BIOS menu.

  • Should I change boot mode from UEFI to Legacy? Please see my update above, my computer won't let change from UEFI to legacy (Unselectable for secure boot) – Nick T Jun 6 '17 at 21:35
  • Yes, In legacy mode you will be able to boot os. You can it from BIOS Settings. You need to disable secure boot first for that. – Ketan Patel Jun 7 '17 at 5:05
