I cloned a disk about a month ago, and it's been working fine. My backup programs will not do system backups. On further investigation, I discovered that what 'used' to be marked as the System, Active and Primary partition is now. I'm surprised the computer boots.
It's Disk 0. How do I make that System, Active and Primary. I have another machine identical to this one, and that is what it shows. The old disk was failing, so I don't want to try booting from it again, in case I need data from it.
Here is a screen shot.
Thanks
