Worked like a charm. I used the diskpart command to make a flashdrive bootable, then I simply copied my Win 7 install disk to the flash drive. Rebooted using the flashdrive as the primary boot source and it ran perfectly.
Hello I am sorry, I have been having the same problem as you, been meaning to get windows for almost a year, but some or the other error always pops up. I have seemed to hit a dead end at the same error as you, but you seem to have fixed it apparently. Can you please tell me how you copied the installer disk on the usb, was it using mac or windows. Any help will be appreciated mate. Thanks.
