I *think* i booted from the flash drive.....
I have a flash drive with a Lion on it, Installed lion and copied the "install.dmg" and I want to erase my hdd with a few passes and re-install lion.
I started my computer while holding down "COMMAND R" and opened disk utility and wanted to erase the hdd that way.
But I just read on a site to do this: "Restart your computer by holding down the option key. You will now be given an option to boot from the DVD or USB drive. Go through the installation, ready to enjoy a new, clean install of Lion."
Am I restarting the incorrect way? But before I re-install lion I want to erase the HDD"
I read some of the articles simsaladimbamba posted but I dont quite get what "To format, erase, or reformat your Startup volume (the OSX volume on your internal HD), you must start your Mac up from a different source: •On Lion, the Recovery HD or OSX USB thumb drive."
Thats what I am doing, by restarting my Mac while holding down "COMMAND R". Or do I just hold down
