So the other day I partitioned my hard drive via windows vista to take windows 7 for a test drive through dual boot before possibly buying it. Everything went as planned and when I turned on my computer I got the message to choose which system to run. Again this was fine until I was finished the "test drive" and deleted the partition and extended it back to my vista partition. But now the boot manager continues to ask which OS I want to run. I have windows 7 deleted. I even booted off the Vista CD and "repaired my system boot" yet it still asks what OS i want to run. Any Help is appreciated!
