7tools Boot Corrector Description:

Boot Corrector is a system utility designed to resolve various problems which users may encounter during the system boot process. These problems may be caused by program errors or user mistakes, or become the results of boot virus activity.
Boot Corrector is purchased as an ISO-image of the bootable disk. You should burn it to a blank CD and keep it until something unpleasant has happened to your system and it can not boot any more. Then you will boot from the CD that you have made in advance and correct boot problems.
Boot Corrector allows you to cure the majority of boot problems for Windows 2000/XP/Server 2003. The key advantage of Boot Corrector is that it can correct the Windows System Registry without Windows loaded. It also helps with other operating systems when common boot problems take place, for example, when a boot virus has corrupted the MBR.
