Uninstall JoeOS

how do I uninstall a dual boot win7 & JoeOS installed via live cd?

you can just delete the JoeOS partition and you have to recreate the windows-boot-record, so that the pc will boot windows, because grub is missing. you need to boot with a windows cd in reovery mode to fix it and make windows boot normally and then repartition the partion that JoeOS was in so windows and you can use it again for anything else.
