I'm dual booting Windows Vista SP164 bit and Windows 7 RC 64-bit. Both are on seperate drives, Vista on C (the boot drive). So far, Win 7 has been fine for the most part, though when I try to access stuff from the C drive it doesn't give me permission sometimes, saying access is denied, and a couple of times, folders created in Vista (both on C drive and on a seperate data drive) have been denied -- once Win 7 claimed the folder was corrupt and the data just disappeared (a checkdisk did not restore it).Vista, on the other hand, has had plenty of problems -- I use a Sager for which Vista 64 bit is the recommended OS, and since Windows 7 runs fine, and both use the same drivers, i assume it's not a hardware issue. So far, sometimes when I boot into Vista, networking gets messed up, and my wireless connection to the home network just seems to not have internet, and it thinks the router is preventing it. Sometimes the desktop just shows up with half the things missing, sometimes half the icons from my notification area are missing and i can't get them even though the processes appear to be running. I've had TONS of checkdisks attempting to run when booting either OS on the C drive.At one point, Vista crashed from a BSOD and booted only into a blank screen with the mouse, but I think that was a graphics driver issue (i was using a glitchy new version which apparently had problems), and when I booted into Win 7, it had no access to the C drive at all -- access denied. However, the backup manager displayed the entire directory tree within it. I had to clean install, but these problems have still been occurring.THe latest problem is, when Vista boots up, just before the log in screen, a message pops up saying \$Mft is corrupt, and I understand this has something to do with the boot sector? So what's going on? Is this a Vista-only issue, or is it some conflict between Windows 7 and Vista?

Vanwaril,Did you run the Windows 7 install from within Windows Vista, or did you boot to the DVD. Some people have better luck running it from within Windows Vista.A number of people have also had to go into their other drives and set permissions for 'Everyone' in order to have free access to the other drive (and vice-versa).

I booted from the DVD. What difference does it make if I installed from within Vista or from the DVD?Also, I didn't set permissions for 'Everyone' in the opposite drive because I was unsure if doing that would aggravate the problem -- the changes checkdisk usually 'corrects' are in the file indices, so I wondered if somehow the security permissions from Windows 7 were being written in a way that corrupted the permissions from Vista, if that makes any sense..Either way, I haven't booted into Vista over the last few reboots, and there has been no problem, so I think the problem only occurs when I go from one OS to the other.

There might be a conflict if both systems have the same computer name.It's a guess.

Hi, I've seen that before when I have had an external hard drive that lost connection or when I've used my USB 2.0 ext. hard drive that uses a seperate USB power source and the power source gets unplugged while the data source is still attached,however... \$Mft usually is visible if you set the "show hidden files and folders" in folder options. I've also noticed if you have this issue externally on a machine and you didn't on another machine... i.e. worked fine on my HP desktop, but not on Dell laptop... it will work fine again on the original machine. This may not help for internal (ide-sata-etc.) HDD's,but it does seem to be about write combining and controlling that precious 1024 cyl. threshold.It mayalso worth checking BIOS settings for dual boot priority. My Dell has 2 hidden restore partitions and my C: drive,if they were all visible,would be my E: or even F:. Very tricky playing with dual installon certain machines with hidden restore partitions... such as Dell or even HP/Compaq PC'S. Toview my Dell's partitions sequentially the C: partition is the 3rd partition. One of the first 2 is actually in FAT format... completely invisible to an NT machine by default. I was wondering... did you dual install clean or on a visible active dual partition? This could be the problem if the HDD is searching for the "NT Loader" that runs all installed versions via boot manager. The choices when booting to choose the OS is much different in Win7 than WinXP. When booting up and logging in, go directly to the user profiles and check all privileges to the HDD and make sure you have all administrator control. Good luck,John
