UPDATE: I have booted into my second OS and the problem still exists, CCleaner sees restore points from both systems and Windows only sees the restore points from the current system. I guess that they are both using the same system partition so the system restore points for both are stored in the same place?

Where did you read this? As far as I can tell dual booting is maybe not extremely common but it is definitely possible and safe and many people do it without any problems. I have also successfully dual booted XP and 7 for a very long time without any problems at all and I am now dual booting 7 and 7 without any problems (besides for the system restore). Now that you mention this I think I have found the problem; after installing both operating systems I used the Disk Management tool to rename my second hard disk and in the process I accidentally click the Mark Partition as Active option. There was no obvious way to undo this and according to a few web pages I found only the first active partition would be used to boot from, and as far as I could tell it didn't cause any problems so I just forgot about it. After you mentioned the active partitions again I did a search to find out how to undo it. Now all the system restore point have disappeared and after manually creating one both the windows system restore and CCleaner show the same thing. I will also boot into the second OS to make sure everything is still working there.

Thanks. So it would be a problem if they shared system volume information? But it also almost seems like you are saying that it is a problem for one to see the other's hard drive, which doesn't make sense to me, I don't see any harm in being able to browse both hard drives from either OS.

I never had any problems with XP and 7 and if I remember correctly I found some people that said that 7 was smart enough to dual boot with XP as long as you installed XP first and then 7. I am not running XP anymore but now just two 7s, here is the disk management on my primary system: C is my primary drive, with my first win 7 installation on it and D is the second, E and F are just extra hard drives. What exactly is System Volume Information?

They're installed on two different hard drives. I'm not completely sure what you mean by this, even though the one drive has another win 7 installed on it, it is still just a regular hard drive so unless I am missing something important I don't see why it would be a problem for me to see both drive from one installation? I have also successfully dual booted XP and 7 before and I have never noticed any problem or clashes between the two operating systems before until I discorvered the system restore points in CCleaner.

I am dual booting two copies of Windows 7 64bit and under the System Restore page all restore points from both installs are shown. The regular Windows system restore dialog correctly only shows entries from the current system. If you would like more information just let me know.
