hello all, i have gotten the .iso working and OS X installed on a secondary disk. i want to thank zeph and everyone involved in getting this release out to the general public

my problem is that after installing i reboot into the DVD to access terminal to use fdisk in order to mark the partition active. after i enter f 2 it says partition disk2s2 permission denied i also try disk2s1 and disk2 and same thing. i am trying to dual boot with a 500 GB western digital SATA2 which has XP installed and a 200 GB SATA samsung which has the OS X installed. my further pc specs is as follows:

LANPARTY UT nForce4 Ultra-D
AMD Opteron 148 2.2 ghz single core S939
ATI 1800XL 256 MB
creative soundblaster extreme music

before install i selected the latest TOS kernel and the MBR bootloader

sorry if this is a horribly reposted question, thank you to anyone for their patience
