Vista start up issue


New Member
so my sister gives me her old hp pavilion dv2000.says her boyfriend jacked it up. I turn it on the first time and never make it past boot up. Black screen says windows failed to and gives me this info:

File: \Windows\system32\winload.exe
Status: 0xc0000428
Info: Windows cannot verify the digital signature for this file.

I have the options to hit enter or esc so i hit enter to continue and i can either run memory diagnostic or try to start windows.i try to start windows and i go to windows error recovery screen with options to enter safe mode etc, etc and none of the options have any positive results. they lead me back to original black screen,windows boot manager with the previous error msg and info.

Any help would be great.My sister doesnt know where any of the original software is so i have no recovery disk or install disks. i dont know what to please
