Now I am really puzzled - mystery active partition
I have 2 HDDs and 1 SSD.
On HDD Disk0 I have Vista which is an active partition (F)
On SSD Disk2 I have Windows7 which is an active partition (C). Win7 was installed with the HDDs unplugged.
On HDD Disk1 I have 2 data partitions. One for Videos (D) and one for Macrium Images (P).
Yesterday I discovered by accident that this Image partition (P) is active. So I cranked up my trusted Partition Wizard and made it inactive. This morning my system would not boot any more. So this time I used my bootable Partition Wizard CD and changed it back to active. After that the system booted as usual.
Would anybody have an idea why a data partition would be set to active and why the system would depend on such a data partition to boot. I am completely puzzled.
Note that I have never used Disk1 for any system installation. It has always been a data disk.
