Hi! I am currently using a Huawei modem, a USB device I use to connect to the internet. I found that when I try to activate Windows with Daz's loader 1.7.7 while the USB is inserted, it fails to boot and goes to a black screen with a blinking line in the upper left hand corner of the screen. But once I remove the USB, Windows 7 starts up just fine and is still activated. My friend suggested that I change Boot order priority, starting from hard drive to cd/dvd to other devices. Didn't work. I even disabled the Boot from other devices option. Although I can live with inserting the USB to connect to the internet each time, it is still a hassle. Any help will be great. Thank you very much in advance.
