Hi, I recently purcchased an OEM version of Windows 7 Ultimate for my desktop. I did a complete erase of my computer and set the boot for the DVD-ROM. It did not recognize there is a DVD in it for some reason. I checked the Windows DVD and it works fine on my laptop so this is not the problem. I then thought there is probably a problem with the DVD-ROM and embarked on the process to make a Bootable USB drive - and set the boot to the USB drive....then got the famous error .... File: \boot\BCD Status: 0x000000f Can an yone clever tell me what did I do wrong ?
