I have a friend whose vista pc will not boot after installing system updates. She does not duel- boot, only runs Vista home. I have tried repairing the problem with the vista dvd, it cannot repair the boot problem automatically. It does not detect the operating system. I am wondering if I can fix it with easybcd by using my vista machine. Any advice is appreciated. I have never used easybcd and want to make sure it doesnt screw up my pc. Thanks.
