now it says "chrootarch" not found.. ahh how i wish i had more knowledge on utilizing x terminal! okay, here's what i did:

sudo gainroot
cd /home/user/archlinux
chmod +x /home/user/archlinux/archlinux
chmod +x /home/user/archlinux/chrootarch
chmod +x /home/user/archlinux/startarch
exit
./chrootarch

after typing "./chrootarch", it said chrootarch not found..
