I'm running a dual-boot of Vista and Jaunty. I installed Jaunty a couple days ago and the upgrade cut off my access to files on the Vista side. I've been trying to figure out what's up with this and discovered that I have a bad boot sector. I ran testdisk and tried to rebuild the boot sector, but it seemed rather worthless as it didn't provide me a set of options when it finished. The only new occurrence was testdisk stating the backup boot sector is also bad. I'm feeling close to a solution but I don't know where to go from here...
