Just tried to install Lion on my MacBook Air rev A. After nearly 3 hours of a grey screen and spinning, I restarted the computer. I essentially now have a brick! Just got Install utility when it restarted, and an option to reinstall Tiger, or use a Timemachine backup. Tried to reinstall from Timemachine backup, but whilst Timemachine is recognised it can't find a hard drive to install on. Any advice greatly appreciated...
Cheers
