I'm getting so stressed over this now, i've had my new machine for 2 days and i've not even been able to use it properly because of different problems. The latest being that I recently installed windows 7 on top of each other by accident (with advice from gorman i tried to format the drive first and do a re-install) However half way through installation i get an error message telling me that there were some missing files and now BOOTMGR has failed to load, so now i cant even install windows! I've tried the automatically repair button, along with all the other options given to me on screen, i cant boot from the hard drive as now there is nothing there, so what do i do? im desperate to sort this out, as right now I cant do anything with it!
