I had two OS in laptop windows vista and linux mint and when I used to start my computer I used to get different option for os like linux mint, linux mint memory check, windows vista etc.. but because of virus windows vista got crashed so I formatted disk drive C: which were containing windows vista and reinstalled fresh copy of vista.. but now when I start my computer vista start automatically, bootloader does not give those previous options to run windows os or linux os..

Is there a way to configure bootloader to get options like I used to get before formatting ?
