I got an Acer Aspire E15 and came with Windows 8.1 pre-installed, and UEFI / Secure boot, would like to install Ubuntu on dual boot, but I have no experience with laptops that have the system UEFI / Secure boot, this is new to me.
So I would like, if possible, that you explain me how to install step by step, and would like to know which procedures and care must be taken to not lose the Windows installation because according to me Acer responded via Twitter "The exchange software is not recommended because some functions may be damaged and may decrease its performance beyond the warranty loss. "
I believe that dual boot is not an exchange of software, for I will keep Windows on the machine, moreover it seems somewhat authoritative by the manufacturer make me use Windows only (installed without my consent). If someone went through it too, could explain how proceeded with these issues, the installation has caused loss of warranty to you?
