Dual boot Xp and Vista (rc2) on seperate HDD's. Today when I booted to
Vista, it did a diskcheck and started working on my Xp partition with the
following message " replacing invalid security ID with default security Id
for the files xxxxxx". The Xp drive was not labeled as "not valid" from the
Vista OS. Thankfully, both still boot, but Vista will not boot without
diskcheck, which I cancel. Any help appreciated.

Mistyped : The Xp drive was now labeled as "not valid"... sorry

Another issue to watch out for is that all Vista restore points are deleted
when you boot into XP.

I've never seen it either, and I dual boot XP/Vista. But my Vista is RTM,
not RC2. Could this be an RC2 bug? Dunno.

What happens if you let diskchk run all the way through? Does it say
the same things every time? If you run diskchk from XP, does it find
any errors?
