I recently bought a new SSD drive for my PC and would like to install a version of ubuntu on it. I installed the drive and managed to get the OS on the SSD but when I boot the PC I'm given no option to choose which OS to use. My boot manager is called ASROCK Boot UEFI

If no bootloader shows up in the boot process, this could be because you installed the bootloader on your ssd. Go into bios and tell bios to boot into your ssd instead of booting into your other harddrive where windows is installed.

you can try

sudo update-grub

and see if windows is detected

  • Hi @Guillaume, Thanks for replying, At the moment i cant access elementary OS. I can only boot into windows – John Smith Jun 20 '16 at 10:56
  • In this case you want to boot with boot-repair (boot via usb or cd), and choose: Recommanded Repair. – Guillaume Jun 20 '16 at 13:17

You can always modify windows so that it loads the ubuntu bootloader instead of it's own. In windows, just open up cmd as admin, then enter:

bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

Make sure that this is actually the right path for the elementary OS bootloader, otherwise your system might not boot at all anymore.

  • Hi @Nordic can you tell me first how to check in windows the path? I just want to be 100% sure i don't brick the system – John Smith Jun 20 '16 at 10:55
  • No idea unfortunately, I'm not too familiar with windows when it comes to lowlevel stuff. If I were you I'd just go and ask someone in an elementary OS forum if they can find out if that's the correct file for elementary or not. Good luck! – Nordic Jun 20 '16 at 11:47

You must type msconfig in the command prompt, start tab, choose "normal boot". Reboot and there you can access the secure boot options normally, which are otherwise grayed out. From there you can choose shimx64 or grubx64. Then the boot will be possible. I had a hard time finding but I got there.
