Boot Camp Utility from Mac went mad itself and now it ruined my partition table. Via Boot Camp Utility, I merged the Mac partition with windows partition. Just to make sure everything went smooth, I used command-line program from Terminal and figured my Mac Partition was labeled as "Microsoft Basic Data". I thought it was weird but the Mac OS X was running without any troubles so I reboot my machine, then my Mac was never able to boot again. After a long wait during the boot, it shows an icon of a question mark within a folder. I restored my Windows from backup image and figured the Mac partition is labeled as HFS sized as 465GB! My MacBook Pro (i7 15") is clearly a 500GB HDD (or technically 465GB), and according to Windows, its HDD has a partition of Windows (301GB) and another partition of non-bootable Mac (465GB). I know the partition table has gone mad and I have a dmg file of Mac OS X which could be used to repair the Mac partition. I bought 10 DVD+R DL's and tried third-party tools to burn dmg file as a bootable disc and nothing seemed to work. Of course, if dmg file was a compressed image, those tools would had decompressed first. When trying to boot from the burnt disc, pressing 'c', 'd', 'SHIFT', or 'OPTION' key never worked. I'm doing this because the DVD came with my MacBook got lost. The main purpose of this whole procedures is to make my Mac bootable again. So if any of the experts from this forum knows how to do any of the following please help me: 1. Creating a bootable disc of Mac OS X in Windows. 2. Repairing the Mac partition in my situation. 3. Make the Mac bootable again. Thanks in advance.
