Hi I am new to this so I am sorry if I make any mistake. Okay, I have sony vaio laptop and i was running windows vista on it. I did a partition and dual boot the system with ubuntu 10.4. Then i download easybcd tool to set windows vista as a default OS to boot with, but accidently in easybcd software i unistalled vista boot loader. now when i reboot the system ubuntu works fine but when i try to load vista its says NTLDR is missing Press Ctrl+Alt and Delete to restart. Then tried to boot from cdrom because i have a fresh copy of Windows 7. the system doesnt boot from cdrom. So now i am stuck with ubuntu on my system.
