Hello, i have problem with my Laptop (Lenovo G50-30)

I have Windows 8.1 , but recently i had some problems with it. It`s slow and I`dont like it. I have Windows 10 Pro 64bit on CD , for multiple users.

I wanted to reinstall my windows , but i can't ... cuz there is no Boot Menu, like in Windows 7,10
When i insert my disc , how can i do that it`s booting from disc.

I`was trying to go in BIOS and see if i`can do something but i can't seem to find anything...

I`really need to install new OS.
Also sorry for my bad english, not my native language.


Thanks
