We recently acquired 30 x Veriton x4640g which come preloaded with Windows 7 Professional. I have been trying for the whole day to install the Enterprise version of Windows 7 and it keeps freezing on the select language / time zone.
Although there is nothing wrong with Windows 7 Professional, it's a company policy to install only Enterprise Editions of Windows on all our systems due to the volume licencing and standardising the entire environment.
I have changed the BIOS mode from UEFI to Legacy, tried installing from a DVD and USB, I even used different brands of DVDs and USBs but the problem persist.
My next step is to upgrade the BIOS to see if that helps, a colleague also suggested network boot via Windows Deployment Services, I doubt that will fix the problem but I am grabbing at straws here any suggestions.
