Hi! The install stops making progress at 85% expanding files. I left it for 45 minutes and it still made no progress although it is clearly not frozen as it responds to cancel commands etc. Tried formatting and making partitions again with no luck. Any suggestions would be appreciated! It is a completely new clean machine with no other OS. specs : 1 DFI LanParty DK X58-T3eH6 Socket-1366, ATX, 1xGbLAN, DDR3, ICH10R, SLI&Cross1 Corsair XMS3 DDR3 1333MHz 6GB CL9 Kit w/3x 2GB XMS3 modules, CL9-9-9-24, for Core i71 Intel Core? i7 Quad Processor i7-920 4,8GT/sec, 8MB, Boxed1 XFX GeForce GTX 260 896MB PhysX CUDA PCI-Express 2.0, "BLACK", 2xDVI, HDMI, Core 216, F1 USB2 MULTICARDREADER 3.5" sort for CF I/II,SM,MMC/SD/microSD,MS,xD (bulk)1 Sony NEC Optiarc DVDÃ‚Â±RW burner AD-7200S, 20x, SATA, Black, bulk1 Western Digital VelociRaptor 150GB, 10000RPM, SATA, 3 Gb/s, 16MB p.s. downloading build 7057 to see if I have more luck there 7057 worked fine.
