arcticsheep Posted November 8, 2008 Share Posted November 8, 2008 I had windows and mac working perfectly (mac being the active partition, which has the bootloader to give me the option of windows or leopard [i think]). But recently I reinstalaled windows because it started acting up, and i haven't really touched mac ever since because obviously windows resets the active partition to the vista partition. so eventually i wanted to boot into mac so i decided to change the active partition to my leopard partition, which i did successfully, but now all i get is "boot1: error" when i start it up. what gives? thanks Link to comment https://www.insanelymac.com/forum/topic/135385-boot1-error-after-windows-re-installation/ Share on other sites More sharing options...
MacNutty Posted November 9, 2008 Share Posted November 9, 2008 Try this: 1. Boot with OSX install disk with option -s 2. At command prompt type fdisk -e /dev/rdisk0 (replace 0 with your disk no.) 3. flag 1 (replace 1 with partition no. where OSX is installed) 4. write 5. update 6. quit 7. reboot If still problem, then you need to install bootloader again.

arcticsheep Posted November 9, 2008 Author Share Posted November 9, 2008 Thanks I already did that, it didn't work... I it's my first disk (0) and third partition (3), but that's what gave me the boot1 error. How can I reinstall the bootloader? I tried to find it on the internetz but I had trouble working with the "startupfiletool" and "bless24"? And how can reinstalling windows affect another partition's bootloader?
