Q: Mac OS 10.7 upgrade failing at disk selection screen.  "this disk cannot be used to startup your computer"  It is the current startup disk on my 10.6.8 installation.  What am I missing?

Upgrading to MAC OS 10.7 on a Macbook Air:

 

Model Name: MacBook Air

  Model Identifier: MacBookAir3,1

  Processor Name: Intel Core 2 Duo

  Processor Speed: 1.4 GHz

  Number of Processors: 1

  Total Number of Cores: 2

  L2 Cache: 3 MB

  Memory: 2 GB

  Bus Speed: 800 MHz

  Boot ROM Version: MBA31.0061.B01

 

Available Storage 17.5 GB on a 60.3 GB drive.

 

On upgrade installation message says " you cannot use this disk to startup your computer"

 

My current OS  is 10.6.8 and is using this disk as the startup volume.  How do I proceed?

MacBook Air, Mac OS X (10.7)
