ارجو مساعدتي فى تنصيب ubuntu بجانب windows 10 حيث قمت بحرق اوبنتو على dvd وقمت باختيار تجربه اوبنتو ثم بعد تحميل سطح مكتب الاختيار قمت ب اختيار install ubuntu 16.04.2 lts
بعد اختيار اللغه واختيار تحميل التحديثات ظهرت لى رساله الخطأ تلك
Force UEFL installation
This machine's firmware has started the installer in UEFL mode but it looks like there may be existing oprating systems already installed using BIOS compatibility mode if you continue to install debian in UEFL mode it might be difficult to reboot the machine into any bios mode operating systems later
If you wish to install in UEFL mode and don't care aboutkeeping ability to boot one of the existing systems you have option to force that here if you wish to keep the option to boot an existing operating system you should choose not to force uefl installation here
ثم خياران back و continue in uefl mode
ارجو المساعده
