I had trouble setting up a new Lenovo 110 17ikb to dual boot with Ubuntu on a Windows 10 machine. Here are some steps that I took to resolve this, including the to not so successful ones
- Started with just an install of Windows 10 on a new 2017 Lenovo 110 17ikb.
- I first freed up some space on the partition using diskmgmt.msc in Windows. I might have overdone it leaving 250GB.
- I had an existing Ubuntu bootable USB drive (16.04). Tried using the Windows 10 EFI boot from USB option with that drive (from the Recovery settings screen) but that did not work. System said that it could not find the USB drive on reboot.
- I then created a new USB ISO image (Ubuntu 16.10) using latest Rufus which should support BIOS and UEFI. Rebooted with USB as boot device but that did not work either. System did not find any bootable USB devices.
- I then created a new 16.04 USB ISO image (Ubuntu 16.04) using latest Rufus using same process as in previous step. Rebooted with USB as boot device but that did not work as well. System did not find any bootable USB devices.
- From the BIOS or UEFI settings I switched to Legacy mode and Legacy boot order (something like that). Moved Boot to USB to top in boot order. Now my USB drive was recognized on boot. The problem was that when trying to install Ubuntu it wanted to overwrite the entire drive (not install alongside Windows Boot Manager) so I had to stop this.
- I was about to give up here …
- I then tried to boot to an older Linux (FC9 i think) ISO CD that I had from before. Again selected EFI boot from CD/DVD. Again it did not work.
- I kept at it.
- I now burned a DVD ISO image (using ImgBurn) of the 16.10 version I downloaded eralier.
- Selected again to boot from EFI CD/DVD. Restarted PC and to my amazement it worked. It started up booting from the DVD. It booted into Ubuntu. I started the installation and it was successful. I did see the option to install Ubuntu alongside Windows Boot Manager. Now when starting up PC I can see options to boot into Ubuntu or Windows.
- The only unusual thing while installing Ubuntu was that I was not prompted to choose the free space partition I created in first step to install Ubuntu there. It luckily did install Ubuntu in this free partition. I would readd this step (it was there before) just to make installers a bit more certain that the correct location will be used.
- That’s it. Took much longer than it should have. Hope it helps someone.
