justin1986 Posted June 7, 2008 Share Posted June 7, 2008 Since updating to 10.5.3 I finally found my OS X install to be so stable, that I decided it was finally time for that glorious moment - formatting my windows partition. I hadn't booted into it for over a month now, and I definitely could use the storage space. So I went ahead with Disk Utility and made myself a nice HFS+ partition. Only thing is - The Windows partition was of course the first one on the disk. I got an "Error loading operating system". I then booted using my Leo4all install disk, and all worked. I then looked around the forum, and tried to update the MBR using "fdisk -u /dev/rdisk0". Since then it only gives me the blinking cursor on boot. (still boots using dvd though) Getting around to my questions: - Have I f*ed up my MBR by doing the fdisk thing? - Is it even possible to boot if the only OS there is is on the second partition? If yes: how? If no: what is the best way to "copy" my second partition to the first one?
