I have burnt Ubuntu 14.04 64bit using Unetbooting on a USB flash drive and tried several times to install Ubuntu on my new computer which has no software on it and Gigabyte GA-Z97P-D3 motherboard. It is a UEFI Dual BIOS and I guess the problem has something to do with UEFI.
It may also worth mentioning that the flash drive is formated to ext4.
The installer just hangs on Unetbootin blue page and does not proceed. I have also tried Ubuntu 12.04 but got the same resutls. Appreciate your help to resolve this.
