clamothe Posted June 3, 2007 Share Posted June 3, 2007 I was dual booting 10.4.8 & XP via the darwin bootloader. Everything was happy, until I formatted a seperate hard drive using the windows install CD. In the process, it replaced my MBR with NTLDR. I can boot windows via NTLDR, no prob. I tried using the chain0 method, with no sucess. Choosing the chain 0 method in the bootloader simply sends me back to the boot loader. My goal would be to reinstall the darwin bootloader. `fdisk -u /dev/rdisk0` should handle this fine, right? Well, at least from the installer's terminal, it doesn't. I tried it, but NTLDR still stands. Disk Utility, loaded up from the install CD, shows both my XP & OS X partition's, and verifying my OS X partition suceeds. I also tried selecting my Mac OS X as the startup disk, via the install CD, but that also is to no effect. XP: disk0s0 OS X: disk0s1 How can I get into OS X ? Reformatting is NOT an option. RESOLVED: As it turns out, the darwin boot loader WAS in the MBR, it was just set using a 0 timeout and the NTFS partition was active. Link to comment Share on other sites More sharing options...
l3opard Posted June 5, 2007 Share Posted June 5, 2007 Could you please let us know how did you resolve it...It sounds like a similar problem that I have. But in my case I first installed grub and it didn't give me any option for osx so I deleted the partition which had linux on it ...but grub stayed on..and now i have a grub loading error..so basically i think i overwrote my existing booting which worked fine and i have not idea how to set it back ... and i too cannot reformat the whole thing...i have way too much stuff on there.
