I've hit a snag on upgrading my netbook to F17. Every time I go into the upgrade section I get a dialog saying my root volume is dirty and to reboot into linux, have it clean the FS and restart the upgrade.
Unfortunately, no matter how many times I've rebooted I keep getting the dialog. I'm not really sure where to go from here except to manually check the FS, but I can't fix any root volume errors since I have no way of unmounting the FS on this machine.
Ideas?
