Today I was copying my iPhoto library to an external drive which got to 80Gbs then failed. I tried to eject the drive, but it wouldn't let me. I rebooted the computer. I now get the flashing question mark folder! I assume my hard drive has failed. I have a lion boot disk, by my SuperDrive is dead. Can I copy the lion boot disk to an SD card and boot from that? How do I do this on widows?
