I've tried to use boot camp to install win xp after i removed it from Vmware, but there was a warning in boot camp when i tried to make a 20G partition for xp, it recommended me to rebuild a partition(means restore the OS), and that is the hell thing i would never try because i just restored it days ago!! It reminds me of iDefrag, i decide to try it on my HD to see if it can help or not. I need CDmaker to create a bootable cd so i can run iDefrag without mounting HD, but there is a problem when i create it: Coriolis CDmaker failed to create a template from that installation media, try again or use an alternative source. I've tried: 1) Mount Mac OS X Install disk 1 DVD; ----- Failed!! 2) Using Disk Utility in the Utilities folder to create a new image of the Mac OS X Install DVD. Change the Image format option from "compressed" to "read/write" (reference:http://hopeforcedmetoblog.blogspot.com/2009/02/leopard-boot-disk-for-unibody-macbook.html) ----- Failed!! Failed Failed Failed, always failed !!! it really sucks! My last option is using time machine to backup OS and move it to a new portable disk, GOD!!! I really hate backing up date!!! >"< Any ideas?!!!!!
