I am using windows 7 32 bit. Hp dv5 1050ei,core 2 duo, 3gb ram 2ghz. it was before vista on my laptopand i clean installed windows 7 and from last 2 months it was working fine but tonight when i was starting my laptop it doesnt started and it was black screen completely. i tried many times but failed. then i used windows 7 recovery disc but it is not reading anything from disc i can hear the sound of disc running but nothing else happens. i tried many times but only twice i saw "CDBOOT ERROR : BOOTMGR COULDNT BE FOUND" please help me how i can repair this i am literally pulling my hair. i tried to boot from disc by pressing F8 but after pressing F8 4 or 5 times a loud BEEP sound comes and nothing else happens. i have windows 7 repair disc (but it is not getting read) but dont have instalation disc. i have vista repair disc also but that is even not working.
