i have installed windows vista, unknowingly i changed the active boot option from 'C' drive to some other drive.now my lap doesnt boot and shows BootMGR missing, Press ctrl+alt+del to restart and also not even open the BIOS setup window.usually i install the OS by using USB Flash drive(since CD drive not working).(Laptop Model : compaq presario C700)How to recover this problem. Please help me....,Thanks in advance
press ctrl alt delete and then press escape and do a factory image restore
here, okorder / the steps are the same. except that since you cant get into vista. you just put your vista CD in and use it to open the command prompt. (its on the disc, under recovery options)
