Hey guyz, I created a Lion recovery flash drive using the tutorials available online (restoring the flash drive using the InstallESD.dmg image) however when I try to boot my macbook from this drive, after a while, the apple logo disappears and turns into something like a "do not enter" sign. I would appreciate any help regarding this issue, and if anyone has other alternatives to perform the clean install without downloading from the internet I would be appreciative of that too.
