Thanks but i'm not sure to understand. The post says:
"to run the file uninstall inside /darwin/, the MBR and DBR will be restored. Reboot your computer. If ok to delete the following files: boot, btldr, btldr.mbr and the folder darwin"
Is it good english?? I really don't understand the step by step to uninstall it... Also i'm really scared to reboot my computer now it's working (I know I'll need to!) and when i installed bootthink the install failed with an error message si i'm not sure it is well installed... Can i uninstall it directly from Leopard? Thanks again!
