I have also an Acer Aspire VN7-592 G with Windows 10 pre-installed. I am trying to install Ubuntu alongside Win 10 in dual boot, but no matter what version I put 14, 15, 16 at boot I have no option of booting Ubuntu in the boot menu in UEFI mode. Secure boot is disabled as well. If I try to boot it in Legacy mode, and choose Ubuntu the PC is freezing. I have no idea how can I fix this so that I can have Ubuntu and Win 10 alongside in dual boot.

Any help would be apreciated.

Try disabling Windows fast startup under Power options and reboot in UEFI mode.

  • I did it. In fact with that I have started the installation. I think it has nothing to do with it.

  • Which software to create live USB? I tried Rufus under Windows with no success. If you have the possibility to use Ubuntu to create the boot device try this guide link. The CLI method worked great for me.

  • I use PenDrive and Lili USB creator. I succeded to install ubuntu but the problem is that it is installed on my partition D( I have partitions) but at boot it enters directly in WIndows 10 and there is no way to get Ubuntu in the Boot Menu

  • Did you set a partition for grub? In UEFI dual boot you shouldn't set this, grub automatically recognize EFI Windows partition and installs inside of it.

  • I only boot from the USB key than I followed the steps for a normal installation. I choosed the other partition drive( I have two partitions in win10 C: and D:) and then it got installed. At reboot I couldn't find Ubuntu in the boot menu because it went to Windows 10. Also there is also no wifi connexion for Atheros in Ubuntu 14.04.

There were some ways to deal with this:

First of all if at all you have installed it under 'UEFI'. Then there will be a way to get to that 'EFI' installation.

According to my knowledge (My laptop) there will be a way through bios.

Go to 'Bios settings' as per your computer. Then go to 'Boot options'. There you should see 'EFI' option.

Then select Ubuntu from it. (I think you will be met with several options please check them one after other)

If you don't like this, I think under 'EFI' in boot-menu you have one option to sign the keys. (It takes merely 5 to 7 seconds to sign keys) (This done from 'EFI' under 'BIOS' Your operating system will not be loaded to do this)

Then Reboot your system, you will be met with choosing of operating system from windows menu. If this didn't work for you.

Once you check-out this application 'Easybcd'. Try it, I Think this will work for you. It makes a indirect link to the 'MBR Partition' so that you can boot from other drives as well.

But for 'Easybcd' to work your boot-loader should be installed on that respective drive.

I hope this was helpful.
