Bad idea. I keep getting errors when expanding files. same error 0x80070570. I'm currently redownloading the iso and going to try a bootable USB instead of a dvd. I've tried removing one or the other stick of ram, same problem. Changed from AHCI to RAID to IDE, same issue. Deleted all partitions on drive using Partition Wizard Mini bootable cd. recreated a primary partition in NTFS format, still the same problem. Some help would be appreciated.
