Re: wait for it...
Trouble is when you get a failed machine still under warranty with a warranty seal.
Do you break the seal or not? In the past you didnt have to, you could choose an alternate boot source, and run your repair tools. Now you have to fight with the system to get the UEFI option screen.
Not a nice situation, when you discover the drive is failing and you lost valuble time in trying to recover their prized memories. (Its the Old Dears that generally loose the most)
