I've got a really weird scenario:
I've installed Vista on one of my partitions, after a few days it got
corrupted, so i've installed another version on a different partition
(different disk as well). I've since deleted the first vista
installation.
Now vista works perfectly on my other partition, no problems. However,
when looking at the disk management I can see that the old vista
partition's status is:" Healthy (System, Active, Primary Partition)"
whereas my working vista partition is: "Healthy (Boot, Page File,
Active, Crash Dump, Primary Partition)"
My vista partition is not a system partition. This causes some
problems, as I can't format the old vista partition.
Trying to disable the disk at startup and booting with the Vista DVD
doesn't help (it recognizes some problem but when rebooting, nothing
happens, no loading of anything).
Is there a way to assign the 'System' attribute to another partition
and/or to remove the 'System' attribute from a partition?
