no operating system disk. I`m on the road (on the way home from Afghanistan)
Right now I have the Apple Logo and progress indicator (spinning wheel). It usually lasts about 5 minutes and then the screen goes grey... or blue... or grey and then blue.
Tried to reboot in safe mode but I got a `not permitted`kind of icon (like a no smoking symbol minus the cigarette)
No other Mac around. No firewire cable. Pretty basic - just my Macbook and the power cable. No software, startup disks, etc.
