I have a Toshiba satellite laptop that came preinstalled with Windows 7 then I had it upgraded to Windows 10. I decided to upgrade to 16.04. So I made a bootable USB and set my boot order accordingly. It booted straight to Windows. So I redownlaoded it and tried again with the same result. Next I made a bootable disk and the same thing happened. Has anybody run into this problem before and is there a workaround? I know that wubi isn't supposed to work for W10. Thanks in advance.

    there seems to be an issue if you are using uefi .. I found when booting my PC from a USB i needed to make sure that the USB stick was plugged into a USB 2.0 port then I had two options for booting to it... just a normal one and a UEFI one ... if i chose the normal one it would boot to it ... if i chose the UEFI one it would just go straight into Windows.. this may be your issue .. not sure if you are dealing with UEFI tho – John Orion Jun 01 '16 at 02:37
  • In my case I can press 'f12' on booting and it will take me to a 'one time boot menu' where i can select which device to boot from (internal HD, USB stick, CD/DVD drive). Windows is quite likely to be using UEFI to boot, so select to boot the USB stick from the UEFI Boot Options. Let us know if that works. – pHeLiOn Jun 01 '16 at 02:48

At boot, open your boot menu (usually f2 or escape), and select "cd-rom device" or something like that.

Good luck, I hope this helps you.

Disable Fast startup and hibernation in Windows - so boot into Windows - open command prompt as administrator and execute : powercfg /h off. Open Windows Control Panel, go to the Power Settings and uncheck Fast startup. Shutdown the PC completely - do NOT reboot. Boot into BIOS and select the Ubuntu installation USB drive you created marked with UEFI in front to boot from.
