I just bought a Lenovo Ideapad 100s, and it's preloaded with Windows 10 Home Edition. The software on the computer doesn't allow me to access the boot menu to boot from the USB. Do any of you know a method to force the boot from the USB?
I, you can access the BOOT menu by F12, or with the NOVO button right the battery indicator. Note that this PC is 32bit UEFI only, so you had to include bootia32.efi file in the BOOT folder in your USB drive. Here the precompiled file: https://github.com/hirotakaster/baytail-bootia32.efi. The state of the art is that you can achieve WIFI working patching the kernel, see https://plus.google.com/+IanMORRISON works to get a custom ubuntu ISO (Wifi, in the latest, work out of the box). For the audio, check the merge in Linux-next and Linux 4.9, changes are working in the shadows ;)
