Nightkrawler Posted January 2, 2010 Share Posted January 2, 2010 sure Insert Mac OS X Install DiscReboot. Hold down C key during reboot Do not start the install. From the Utilities menu, select Disk Utility Select your hard drive from the list and then click the Partition tab / button. Click the Options button and select ?Master Boot Record? as the partition scheme. Click OK. From the Volume Scheme drop down list, select 1 Partition. Select MS-DOS (FAT) for the format (not that this matters since you will reformat it using NTFS during the Windows install). Click Apply. Reboot. Hold down the Alt/Option key turning reboot. When the graphical boot menu appears, hit the eject button. When the graphical boot menu appears, hit the eject button. Take out the OS X Install Disc and put in your Vista with SP1 install disc. sourceMaybe removing all other partitons in the setup of windows would be enought but the hdd still would be in "guid" partiton scheme afaik. Also its recommended to have osx at least installed on an external drive for possible firmware updates :) Link to comment Share on other sites More sharing options...
Phantom Helix Posted January 2, 2010 Share Posted January 2, 2010 If you are Installing Windows 7 x64 You can keep GUID partition Table, although that is an experienced user kinda thing. Some Mac's win7x64 might even do it automatically when formatting the entire system drive Link to comment Share on other sites More sharing options...
