My OS drive is no longer "blessed"

[VideoBeagle]

The SSD on my MBP, that houses the OS, is no longer blessed, so I can't set it as the start up drive.
Computer boots fine...takes a long time as I guess it seraches for a way to start up before using the non-blessed drive.

I can't figure out a way to fix it, short of a re-image, which I don't want to do, because it's a pain, but will unless someone has some advice?

I am not sure what you mean by 'blessed' og 'not blessed', but I assume it is this:
Go to System Preferences -> Start Disk -> Select your boot drive.

What MacOS versions on the MBP and the "non-blessed drive"?
What year is the MBP?

I thought you meant it just booted slowly, because you said it booted fine?

Hold down the Alt-button upon start, and see if you can see the drive. Otherwise it is likely dead.

I seem to have this in my utilities folder.
It looks to be an AppleScript that can bless a volume?
Not sure if it will work in your case, or not -- no promises.

Paste the following command into a Terminal window:

bless --info

Press the RETURN key.

Copy and paste (drag-select the text in the Terminal window) the output and post it here.

There's good information on blessing on the CCC site:

So the drive is greyed out, or a message tells you that the drive is not blessed?

Thanks for the hints.. I'll give em a try later and report back.
(the Drive used to be blessed and fine..it just one day...stopped being so).

Never got back to this... seemed to be aproblem with the "blessing" tool, rather than the drive.. I erased the whole drive and did a fresh (and upgraded) os install.
