Windows 7 Dual Boot Help? -

I want to dual-boot my Windows Vista computer with Windows 7. I know how to do the actual dual-booting, but I want to know how to undo the dual-boot when Windows 7 stops working. I have a general idea that I can just delete the partition and re-size the one which has Windows Vista on it. Will this method work? Are there any pitfalls or things I need to know before attempting this? Thank you in advance.

The most important thing when dealing with partitions, ALWAYS backup BEFORE! (sorry for caps). Anyway, yes, I don t see any problems with that method. Windows 7 can use unused disk space on a existing partition to create a new one. Then you can use vista s built-in disk manager to remove the Win 7 partition and resize your Vista partition.
