sse Posted January 21, 2007 Share Posted January 21, 2007 (edited) Hi all I accidentally installed GRUB to the boot sector of my osx partition, so if I try to chainload osx from another boot loader in the mbr, it just fires up grub, and if I try to chainload osx again from grub, I get an hfs+ partition error, cause the boot sector is screwed :/ how can i restore/ rebuild the boot sector? using 10.4.8 edit: SOLVED! ok, that did it: booted from install dvd, fired up a terminal dd if=/usr/standalone/i386/boot1h of=/dev/diskXsY bs=512 count=1 bless -device /dev/diskXsY -setBoot didnt have to fiddle with startupfiletool Edited January 21, 2007 by sse Link to comment https://www.insanelymac.com/forum/topic/39395-solved-boot-sector-screwed-overwritten-by-grub/ Share on other sites More sharing options...
