I had windows 10 installed and wanted to dual boot it with ubuntu. Installed ubuntu with "install alongside windows" and installation completed successfully. But after reboot the laptop booted straight to windows without allowing me to choose the operating system.

I tried this, but it didn't solve the problem

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Tried liveCD boot-repair, did nothing.

And also tried easyUEFI, there are two options and the second one booted to a black screen with something written, but it seems like it had nothing to do with ubuntu. EasyUEFI screenshot

Secure boot is disabled, and in BIOS I can choose between Legacy BIOS and UEFI, Legacy BIOS is chosen by default, don't know if this has to do with anything.

  • Try disabling fast startup option in windows machine and try. Disabling fast startup is mandatory for dual boot. Look here for a tutorial on disabling fast startup --> howtogeek.com/243901/… – Emmanuel Giftson Jan 16 '17 at 14:33
  • The only valid answer in the link above is oldfred's and it's applicable to the mentioned model only. Please edit and update your question with your hardware specs. Some models do need additional steps, often model specific. Also, any factory installed Windows 8+ is in UEFI mode; any other OS in multiboot should be installed in the same mode. Do the other way if you installed Windows yourself and explicitly booted and installed it in Legacy mode (lot's of users do the same dumb thing, I don't know why). – user589808 Jan 16 '17 at 14:50
  • In addition to hardware, if you ran Boot-Repair post the link it gives for its Summary Report. help.ubuntu.com/community/Boot-Info Note that now Boot-Repair can copy shimx64.efi to /EFI/Boot/bootx64.efi to use fallback or hard drive UEFI boot entry as in first comment above. – oldfred Jan 16 '17 at 15:04
