Error with dvd installation

I spent hours trying to install the dvds. (standard version.) every time i arrive at dvd nr 8 i receive an error and installation stops. Any ideas how to solve this?

Took me ages as well , installation crashed every 30 mins or so. Then you have to start again…
Disc 1, 2 3, 4 5, 6 etc… Eventually got it installed after about 8 hrs.
But now its updating online with another 50Gb update!
Not good Microsoft for a £60 purchase!
