Hi All! I need a help with updating BIOS in my Acer Aspire E5-511 notebook. Now notebook is working under Ubuntu with BIOS version 1.03 while the latest version is 1.08. Ubuntu uses grub loader with UEFI suuport. Unfortunately Acer does not provide any update utility rather one running under Windows 8.1/10 x64. I've tried to use bootable USB with Windows PE 8.1 x64, but it was unable to load OS nether in UEFI nor in Legacy mode. Is there any way to successfully update BIOS in my conditions?
