Make a bootable Lion disk for fresh start I just bought a used MacBook Pro from a friend. He left the OS discs in Iraq so he did not have them to give to me. The laptop is currently running 10.6.8.

I would like to start with a fresh install. If I upgrade to Lion and then follow the instructions here to make a bootable disk, can I wipe the system and start fresh?
Yes. I've done this before multiple times.

Pay attention to the following during the installation:


Enter Disk Utility to format the disk.
In the tab select partition. Then click on option and select: Format as GUID


Otherwise the drive won't be bootable.
