SteveStar Posted December 20, 2006 Share Posted December 20, 2006 You have to set your osx partition active. Link to comment https://www.insanelymac.com/forum/topic/36376-help-1046-clean-installation-on-a-toshiba-laptop/#findComment-258759 Share on other sites More sharing options...
Envying Posted December 20, 2006 Author Share Posted December 20, 2006 I only have one partition, I set it up during the installation. It is supposed to be active in default, right?

Rammjet Posted December 20, 2006 Share Posted December 20, 2006 The "b0" error means that your partition needs to be set active. You do have a single partition on your drive. If you go to Disk Utility and look in the left hand pane, you will see the hard drive listed and below that the primary partition on that drive. It still needs to be set active. Doing this sets a flag in the MBR (Master Boot Record) so that BIOS knows which partition (the only one) to boot. Otherwise, it reads no flag and doesn't know what to do. You can use any Windows/Linux disk/partition software to set the partition active. Or you can use Fdisk built into OSX: http://forum.insanelymac.com/index.php?showtopic=22844 The first time you rebooted, you probably had the DVD in the drive. It's bootloader took care of booting the partition. Once you removed the DVD, the MBR on the hard drive took over and it is missing that information.

Envying Posted December 20, 2006 Author Share Posted December 20, 2006 (edited) Thanks Gurus, I also got it from googling! Can't be happy no more! * Comment 1 (10.4.6): If the installation reboots and you get a "b0 error" you'll need to mark your hard disk partition as active so the operating system will know where to look first. To do this reboot the system and boot to the DVD. When you see the initial prompt hit F8 to enter some additional options. Start the installation dvd image in single mode using the "-v -s" flags. Once a prompt appears enter "fdisk -e /dev/rdisk0" (depending on your drive, this is the typical primary disk). Use the command "print" to display a list of partitions on the disk. Find the partition number for the one where you installed Mac OS X and then use the "flag" command to mark the partition as active ("flag partition_number"). Save and quit ("quit" saves changes, "exit" does not) fdisk and reboot. The installation should continue now.
