Windows Vista/7 Boot Stops at Black Screen with Blinking Cursor

If your windows (Vista or 7) machine repeatedly stops at a black/blank screen with only a blinking white cursor in the upper right hand corder, then I may have a solution for you:

1.) Boot from the installer CD

2.) Launch repair console DOS prompt

3.) enter the command "diskpart" at the command prompt

a.) ***Note: you can type "help" at any time while in the diskpart menu to get a list of possible commands

b.) type "list disk" to show all disks in the system

c.) type "select disk #" where number is the number of disk you need to view

d.) type "list partition" to see what partition number you need to make active (the one that Windows is actually installed on)

e.) type "select partition #" where number is the number of the partition that you need to set active

f.)type "active" This should activate the currently selected partition so that the following commands know what partition to set as the bootable volume

4.)bootrec /fixmbr

5.)bootrec /fixboot

6.)bootrec /rebuildbcd
