How to completely clear the restore genie

I used to install the restore genie 6.1. Due to system problems, I re-went to go to an XP portal. When go restarts and enters the system configuration, the restore genie was damaged, the system installation cannot be completed, and then I start to reinstall the system with the original version of XP, or not .... dizzy! I 'd like to think about it: do not install XP after starting with a boot disk, but first enter dos, execute: fdisk/MBR and then restart the system. Now the system can be installed normally. everything is normal! No ..... when I want to reinstall restore genie 6.1, I am prompted that you have installed a similar version. please uninstall it before installation. Then, enter the 6.1 installation package. click execute. /CHT/rg/uninstall... OK !! Everything is normal !!
