I do not need a solution (just sharing information)
Occasionally when I boot into the recovery screen (using LOR) and select a date recovery SSR shows invalid target drive.
The remedy is to highlight the recovery point and select edit, then select the target volume and then OK.
Then go back to the recovery screen and select recover my computer, select the date recovery point and the target becomes valid again.
I had this issue when testing last year and I would have thought by now this issue should have been resolved.
I did say when testing that I would monitor the situation and report accordingly.
When you need to re-image a machine this sort of thing shouldn't be happening.
