Thank you very much! I reflashed the BIOS you modded, but the same thing happened again. I tested with SLIC Toolkit, it has the same screenshots as I posted; and it says "No SLIC" when testing with Uloader/Vista7SlicLdr. This is a new installation of win7, default settings of BIOS were loaded automatically after reboot, there are no loaders installed, no crack used, and there are 26 days left for activation. Thanks again for your help; and if you have some more suggestions, I really appreciate it.
