I guess the easy answer would be that I don't know what that means or what it entails. Sorry, I may be in a little above my head here.
After doing a little research I understand a litle more about what you are talking about. My main question with this would be, will I be able to boot normally using W7 if I format the hard drive. Currently my partitions are as such:
Drive C: Status- Healthy (System, Active, Primary Partition)
Drive G: Status- Healthy (Boot, Page File, Crash Dump, Logical Drive)
Drive I: Status- Healthy (Primary Partition)
I'm not sure what the above means specifically but thought it may help describe what I have. Drive G is the drive with W7 on it and Drive C is the one with Vista.
