I've managed to seriously bork the hard drive that had my Linux system on it. Not a big deal thus far, except that when using cfdisk (with Arch) I cannot set the root partition as bootable.
It says it's an illegal command.
Did I destroy the Master Boot Record? How do I get cfdisk to make the drive bootable?
Was trying to install Arch and once that was done, reinstall sonar linux (ubuntu-based) and let it sort it out. That's the plan, anyway.
