I restored my C:\ IMAGE to replace another OS in a primary partition (XP Pro replacing an XP home edition [I have DVD images of both]) for testing purposes. The result was a single hard drive with dual active partitions! This disk is set as a visible multi-boot. The new partition was lettered differently after adding the partition but resulted with the error "Invalid Partition Table" and no boot up at all-- just hanging on a blackened screen with an error message. Using the DD10 Stand Alone Version (rescue full version) I could 'see' the two primary partitions marked "ACTIVE". I know of another disk manager utility that has a "MARK INACTIVE" function but DD10 does not have this capability (as far as I know). With nothing to lose, I chose to mark a data partition as "active", then I marked the real "C:\" partition "active" again. After this change the second "active" partition was no longer marked "active"; finally only one active partition. Talk about good luck! There was another "safe mode like page" that allowed me to boot into the added partition and after rebooting this page no longer appeared. This 'repair' was short lived since it started to malfunction (slowness, inability to shut down programs easily, inability to connect to the internet and plain old 'strange' behavior). I had to delete this partition as a restore would be much quicker than figuring out a workaround. The image of "C:\" was of XP pro sp2 and only 1 Windows entry in the boot.ini file so I thought I could use it to restore to different partitions as I did with the XP home image partition ( originally an image of the "E" partition w/ only one Windows entry in the boot.ini file [a non system partition]). I guess restoring a system image can only be to the same partition. My non system XP allows me to make multiple instances of itself ( I don't think I could use it to replace the C:\ partition but I have not tried this yet). This is how it behaves on my setup anyways. Other posts lead me to believe that an image restore of a 'system partition' does work on other non original partitions on other setups. Not sure about this. This 'trick' may work correctly when TI10 mistakenly marks two partitions 'active' (probably with DD10 mistakes as well) on the same hard disk.
