Dell XPS 8700 and MS Server 2012r2

Just trying to repurpose an XPS 8700 we acquired and use it as a software testing server.  We'd like to install Server 2012r2 on it but have hit a snag.

The disk requests and performs repartitioning without issue, accepts the license code, but pauses and eventually fails at 91% of "Getting files ready for installation".  At 91% it will sit doing nothing until you try to intervene (open disk drive for example), at which point it says it cannot install required files and throws a 0x80070015 error.

I've tried using the internal dvd drive, an external USB dvd drive, and 3 different disks.  Any thoughts how I can get past this, if I even can?  I understand Dell doesn't support higher than W10 on this box...but hoping that only means they won't support it, not that it can't be done.

Try the installation via a USB stick. You can create a bootable USB stick with the Windows iso using the utility "WinSetupFromUSB":

could be a disk problem - run a diagnostic on it; i use UBCD for this :
Hardware diagnostic CD    UBCD
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems :
