I have a x64 tablet running win 8.1. I am trying to install different Linux distro's. Unfortunately I am having trouble booting up from live usb. I got all set up in bios, turned off secure boot, changed boot order. In bios I use boot override and choose usb. I discovered that bios won't let me boot a fat32 prepared live usb. Only ntfs worked (win 8.1 ntfs usb worked). Linux can't be ntfs prepared in a usb stick to boot from. There are some options missing in my bios which i have seen over the internet like csm?
When I choose "boot override" with an Ubuntu prepared usb stick the only thing that happens is that the screen goes black and then goes back to exactly where I was in bios menu, all this happens in a blink of an eye.
I also tried wubi, Ubuntu got installed, but when I try to boot, it boots to a Windows menu where I get to choose between Ubuntu and Windows. When I choose Ubuntu I get an error saying that I can't start Windows because of a change in hardware or software and I get to see this path \ubuntu\winboot\wubildr.mbr and it says that a file is missing.
Now from my experience on desktops and laptops, after installing Ubuntu or any other distro GRUB gets to take over the boot up and let you choose from the installed systems.
Any help is greatly appreciated.
Got it. Turned out that Bay Trail architecture bios firmware does not support booting outside uefi and has a bug which does not allow to boot anything else than 32 bit os. Linux 32 bit does not support uefi and linux 64 can't be booted since the firmware does not support 64 bit. However there is a bypass, after you have prepared your usb stick, go into the folder efi and copy to there a file named bootia32.efi, which you find here: https://github.com/jfwells/linux-asus-t100ta/blob/master/boot/bootia32.efi. Click on view raw and you will get to download. However this only solved the booting up of the live os usb. After installing I still could not boot Ubuntu.
