www tonymacx86 com/attachments/p5we0121_vbios_2158-2-zip.71854/ I have a Acer Aspire 5755G. I am using an unlocked bios which unlocks power, advanced and uefi options whose link is linked above(sorry cant post links).The original bios did not have uefi boot feature. But there is no option to change efi boot order or add a new efi file. I extracted the bios using Phoenix tool and i found that there are many options in the bds module which allows to change efi boot order and other options that is not appearing in my bios. Is there any way to unlock these ? I also have a problem when win 10 is installed in uefi mode, fast startup doesnt work properly. It wont boot the first time (no bootable device insert boot device and press any key). But when I restart the laptop it would boot properly. This problem does not arise when win 10 is installed in legacy bios mode.
