When I tried to boot from a USB stick on my IdeaTab Miix10 through the Advances Startup Setting from Windows 8, I always get an error saying 'Your system doesn't have a usb boot option, please choose another option'. But it is bootable on my laptop.
I already disabled secure boot through the UEFI firmware settings (used advanced startup settings too), so i'm wondering if the IdeaTab is able to boot from an USB stick and if yes, how?
You maye be also experience this:
When user presses Power and Volume Up keys to enter Novo Menu, they cannot find the USB device or SD card under Boot Menu
There are things you have to take note:
1. Miix10 BIOS is Pure UEFI, only support UEFI boot, does not support legacy boot.
2. Miix10 only supports USB boot by WinPE, the Boot Menu only shows USB device name if and only if that USB device contains WinPE boot up files.
Notice: If device cannot be recognised, please wait for a while before selecting Boot Menu.
Hence, please make sure your USB stick adhere to what's required as stated above.
