This question already has an answer here:

Today I installed Ubuntu on a partition on my Hard drive, which already had Windows 10 installed. When I boot up my laptop Windows Boot Manager automatically boots into Windows. I have heard that I need to enable GRUB but I'm not even sure how I can get back into Ubuntu. I tried enabling UEFI in boot options but I can only see Windows Boot Manager and not an option to boot into the Ubuntu partition. Any help would be great.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • If Windows is UEFI which all new systems are, you want to be sure to install Ubuntu in UEFI boot mode. And how you boot install media UEFI or BIOS/Legacy is how it installs. If you installed in BIOS/Legacy mode, you can use Boot-Repair's advanced mode to totally reinstall grub if you boot it in UEFI mode. – oldfred Dec 8 '18 at 16:53

Enable legacy support in bios. Then go to boot order and put usb first. Reboot. Hit f12 for boot options. Select usb and it should boot.

  • Oh im sorry i see now you put it on your hard drive. In that case just enable legacy support in bios. Reboot. Hit f12 and boot the linux os. – Storm Sowards Dec 8 '18 at 1:07
