I have a 2008 MacBook Air (MB003LL/A / MacBookAir1,1 / A1237 / 2142), and I am trying to reformat it with OS X 10.6 Snow Leopard, using the retail install DVD image
snowleopard_10a432_userdvd.dmg restored to a USB flash drive with Disk Utility. I do not have an external DVD drive to use.
Whenever I try to boot, I get a "no" sign after a few minutes of waiting after the Apple logo. If I boot it in verbose mode, I get:
USBMSC Identifier (non-unique): AF429H02YE09000451 0x154b 0x7a 0x1100 AppleIntelCPUPowerManagement: initialization complete Still waiting for root device Still waiting for root device Still waiting for root device
...and so on.
Does anyone know how I can solve this issue?
