I have Acer iconia W4-820 windows 8.1 tablet which is an UEFI boot device. its secure boot is enabled. I dont know anything about UEFI hoe to play with it. I just want to try ubuntu desktop images on my Acer Iconia W4-820 device, I made a bootable pendrive when i connect it using OTG cable it dont load booting directly goes to hard disk boot of windows. I changed the boot device priority in UEFI. But nothing works.
Anyone tried booting ubuntu on Acer Iconia W4-820 tablet ? Please I need a help.
I haven't tried but you can enter the BIOS by holding the volume-up and power button (to turn on device). For me it didn't work the first few tries, I guess you either have to hold or release the volume button. When you are in the BIOS screen you can change boot-order to USB but you can also disable secure-boot. With both of these options set and a USB-OTG + bootable-USB-drive it should work I guess.
You can try to disable the "secure boot" setting in the UEFI. Also check if there is a setting for legacy support, if so enable it. It can be that those functions prevent the device from booting into another OS.
