I have recently bought a new Acer V3-772G laptop and now I'm trying to install Ubuntu using a flash drive. This laptop has UEFI, but it can be disabled by switching to Legacy mode. I have done it to allow booting from a flash drive and when I boot it up, I can hear the Ubuntu welcome sound, but I can see nothing on the screen. It's not even purple or black, it looks like it is completely turned off.
Possibly it has something to do with one of the following:
- the laptop has the NVIDIA Optimus system with Intel 4600 and GeForce 760M adapters
- the flash drive has been created by Unetbootin instead of Ubuntu's native flash drive creation tool
- perhaps the UEFI legacy mode interferes with the boot process
I'm not sure what to do and how do I even start to diagnose what happens. Any help would be greatly appreciated!
