Windows 7 installation gets stuck on Expanding Files for 2 hours
So we are using Lenovo machines and on our T430s/X230 we sometime saw machines that would get stuck on expanding files during Windows 7 installation. On these models we could change it from AHCI to Compatability Mode on the harddisk and this would resolve the issue. However on our new T440s and i presume it could also happen on our X240 this problem is occuring again but this time Lenovo and Intel has removed Compatability Mode as they no longer support Windows XP.
Anyone have any idea what could be causing this?
Quick edit: Its worth mentioning that the PC does complete installation just takes 2 hours longer then normal.
