Well thanks a lot everybody for help. I played around with my computer and installed Ubuntu in UEFI. I have never seen such an energetic forum. But now, there is another problem. Sorry :P
Now in my boot menu I have 3 options:
- Windows boot manager
- Linus something. I figured out, it only appeared if when my bootable usb was plugged.
- ubuntu
Well, a good new before, i successfully installed ubuntu and it asked me to reboot. When I did so and clicked on the 3rd option, it booted into windows.
When i clicked 2 and tried to use try without installing, it says "Unable to find a medium containing live file system"
What should i do?
Thanks in advance and sorry for bothering u guys
