I've got two newly delivered R510's and am trying to install Server 2008 R2 obtained from Microsoft BizSpark.
I've burnt the ISO to a 16GB USB stick but although the install goes ahead when it comes to building the desktop for the first time (after setting the Admin password) it stalls on the blue desktop background with no icons and no taskbar.
I've left it running on that screen for hours with now change.
I've killed the partition a good 2 or 3 times, rebuilt it and reinstalled but nothing helps.
I've considered burning the ISO to DVD but haven't got that far just yet.
