If you purchased the USB flash drive version you can download an ISO from Microsoft and use the Windows installation key that came with your flash drive.
If you're installing Windows for the first time, make sure the Windows installer you're using is for a full installation (not an upgrade installer).
My G-Drive 2TB USB3 with Firewire backup is less than 1 year old0G02529 I use this for time machine backups on my Mac Pro Server (Mid 2010)This is one of two similar drives in rotation OS X El Captan 10.11.4 The drive has been giving me trouble for months. After consulting with a G-Technologies agent, I was encouraged to update the firmware on this external drive. But it failed on the subsequent attempt (one hour later)I cannot eject the G-Drive because one or more application is using it. Process failed with this error message:“Updating boot support partitions for the volume as required. Seems everyone is investing so much into sales and they lack support.
I decided to re-format the drive and do a new, clean backup. I downloaded G-Technology_Firmware_Update_Utility0614Installed and ran this on our Mac Pro with only the problematic G-Drive connected. I have been extremely satisfied with the attention given by this forum as well as the tech support.
