It’s a bit frustrating that the X205TA use a 32bit bootloader even when the CPU is 64 bit.
This makes it a bit trickier to boot the X205TA from USB.
If you want to install some Linux distros for example, then continue to read this post.
1: First, “burn” your Linux USB with Rufus for example.
2: Download https://github.com/jfwells/linux-asus-t100ta/blob/master/boot/bootia32.efi
3: Put that file on the Linux USB in this folder: \EFI\BOOT\
4: Start the X205TA, press F2 to get into BIOS.
5: Under the Security tab, Secure Boot menu > Secure Boot Control set to Disabled.
6: Make sure your boot order have USB first.
7: Now, insert the USB and reboot the computer.
Linux should now boot from the USB.
I had problems with the WIFI, couldn’t get it working by the way…
