    I am installing Ubuntu along side windows 10 preinstalled but there is no option “install ubuntu along window“.

    Hi, I just finished going through all the steps that you have in this blog. First of I have a brand new Lenovo Yoga laptop, which I just bought. It came with windows 10. After I installed Ubuntu and rebooted the system it went straight into Ubuntu login screen and now it seems I cant get back to Windows because it does not give me that option at all.

    So my question is did I miss anything in the steps? Also what was the point of step 8 part 2 where we created a partition of 5MB? Was that where grub was supposed to be installed? Is there a missing step of installing Grub or is Grub apart of the Ubuntu ISO image that I downloaded? Please help. Thanks.

      Have you manually created the partitions or you’ve choose to automatically install Ubuntu alongside windows? Also you should check out UEFI settings after reboot -> Boot Options -> BBS Priorities and see what’s the default OS you’ve choose to boot from.

        Hi Matei,

        I manually created the partitions just like the document recommended. As for your next question, I am only able to get to windows now by restarting the machine while I press Fn + F2. When I do that and go to the boot options, I notice it only gives me Windows as the only option for the OS. In other words Ubuntu is does not show up in the list.

    I installed Ubuntu with Windows dual boot. Now I don’t have any grub menu. I can only access windows, but I know Ubuntu is still there and would like to restore or install the grub menu.


    • Matei Cezar says:

      Open UEFI settings after reboot -> Boot Options -> BBS Priorities. From there, on some UEFI machines, you can setup what OS should be loaded by default. However, depending on the motherboard producer, the UEFI settings it might look different.

      You can also run the following command with elevated privileges from Windows OS:

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

    Great tutorial!

    However, now I’m having problems starting windows. Every time I restart or simply sleep my computer, the first screen I see asks me to choose “Ubuntu”, “advanced options of Ubuntu”, “Windows boot Manager”, or “System settings”. When I choose Windows boot, Bitlocker asks for this very very large Recovery Key, which is getting really annoying and time consuming. Is there anyway of avoiding this without loosing my computer encryption/security? I use Windows 10 Pro 95% of my time. I only need Ubuntu for a side job. Is there anyway to boot directly to Windows as a default?

      One small technical correction: its “Every time I restart or HIBERNATE my computer”. When just at sleep mode it doesn’t ask for the recovery key… although after a long sleep my computer eventually hibernates, so almost the same thing.

    My copy of Ubuntu didn’t boot into the first screen shown in step 2, it booted straight to the next one, with a try Ubuntu and install Ubuntu buttons. As for the installation, I didn’t exactly follow the instructions.

    I selected something else, created just one ext4 partition from unallocated space (showed up as /dev/sda5), went back and did install Ubuntu alongside Windows 7 (I used Windows 7 in Virtualbox, I’m too scared to do it on real hardware) and it said that it will write to partitions /dev/sda5 (the one I created) and /dev/sda6 (I guess it cut off something from /dev/sda5).

    Once installed, rebooting the VM boots straight into GRUB, where I tried both options, however mine had 5 options instead of 3. The extra options are:

    Memory test (memtest86+)
    Memory test (memtest86+, serial console 115200)

    I have no idea why these options appeared, but as long as they don’t mess up anything, I don’t care about them.
