installing OS: Ubuntu 14.04 64bit AMD64
device: Asus x205ta
ubuntu bootable usb drive created and BOOTIA32.EFI obtained from internet inserted to /EFI/BOOT/ directory in bootable usb drive.
Currently trying to install ubuntu to a 2nd flash drive. My intention is to keep this 2nd flash drive connected to ASUS X205TA at all times and create dual boot system.(Windows 8.1 w/ bing + Ubuntu 14.04)
Partitioning during installation is shown in this video.
‘/dev/sdb’ is the 2nd flash drive(Sandisk Ultra 32GB)
created three partitions
1. swap (2G)
2. ESP (efi system partition) (~100MB)
3. ext4 space for ubuntu (remaining space)
Bootloader installed in ESP so that UEFI will recognize it.
After installing this way, ASUS x205ta failed to boot ubuntu from 2nd drive.
problem solved(at least succeeded in loading GRUB):
