You probably have boot0 installed on your second drive. When boot0 is configured to save your last choice, it writes a modified copy of itself to whatever disk the BIOS considers to be the first one. Since the boot sector is only 512 bytes, it really isn't reasonable for boot0 to attempt to detect these sorts of configuration errors. Your only boot manager should be on the master, and you should use it to boot all of your operating systems. State Changed From-To: open->closed if you wish to use some other boot manager, you shouldn't be using FreeBSD's as well. When installing FreeBSD, choose 'Install a standard MBR (no boot manager)'. You should configure your other boot loader to boot directly to the slice (or partition) instead of the master boot record. |
Copies partion table form harddisk 0 to hardisk1 (ads's) System and boot: hd0 3.1 G vfat32 (Windows XP) /dev/hda1 6.9 G ext3 (Redhat 7.3) grub on /dev/hda2 hd1 5 G (FreeBSD 4.6) /dev/hdb1 5 G vfat (MSDOS) /dev/hdb2 10 G ext3 (Mandrake 8.2)grub on /dev/hdb6 All items booted from Windows XP BootMgr boot.ini c:\bootsect.os ="Operating System" created via dd if=/dev/drive of=bootsect.os bs=512 count=1 When FreeBSD 4.6 is booted this way it writes the hd1 partition table to hd0 thus crashing all Operating Systems on hd0 How-To-Repeat: Set up as above stated the boot into FreeBSD
