Bootcamp windows 8.0 pro installation issue with early 2015 Macbook Pro

I am having this issue with installing Windows 8.0 pro (and 8.1 pro) on my early 2015 MacBook pro vs. Bootcamp. I have tried different method for multiple times and all failed. Any help is appreciated.

Hardware: (1) early 2015 MacBook Pro with 128GB (13 inches) , (2) Sony USB DVD burner. (3) Two 16 gb flash drive 2.0 version from two different manufactures

Software: (1) 8.0 Pro ISO on flash drive from Microsoft (I have two copies) (2) 8.1 Pro downloaded from Microsoft website.

Note - I was able to download the bootcamp supporting files successfully and copy to a USB flash drive.

Method 1 - Create the installation disk from ISO on flash drive and also tried copying ISO on hard drive (desktop)- failed.

I have a 16 GB flash drive (2.0V) connected

ISO is a valid 8.0 pro copy from Microsoft came on a flash drive.

I have the windows 8.0 pro ISO on a flash drive and plugged in.

Issue - It gets to around 50% of "Copying Windows files..." and then doesn't go any further. 8 hours later, still stuck at around 50%. I also tried to do the copy ISO from desktop. failed as well.

Method 2 - I repeat the above steps with Windows 8.1 ISO downloaded Microsoft website - failed. Stuck at 50% copying windows file for 9 hours.

Method 3 - I burned the Windows 8.0 pro ISO to a DVD and try to do the installation through a DVD instead. DVD was successfully created.

I was able to perform the partition. When the computer reboots, it starts the window installation. However, it got stuck at 7% forever. I tried this multiple times and failed.

Method 4 - I download a 8.1 Pro ISO from Microsoft website, I burned it to a DVD. Repeat method 3, Again, windows installation stuck at 7%.

Method 5 - I called Apple. - What they told me is pretty much repeat the above steps. Still failed.
