flipsoft Posted June 14, 2006 Share Posted June 14, 2006 Just working on a new installation and it installs correctly (I selected the correct options) but after I reboot I get a b0 error message. Is there some special preparation needed for the drive to be bootable? -flipsoft Link to comment https://www.insanelymac.com/forum/topic/19765-need-a-little-help-jas-1046-installs-but-does-not-boot/ Share on other sites More sharing options...
Rammjet Posted June 14, 2006 Share Posted June 14, 2006 b0 error means the partition needs to be made "active" using fdisk or one of the windows partition apps.

flipsoft Posted June 14, 2006 Author Share Posted June 14, 2006 Ok I will try that then. I used the disk utility from the DVD to format the disk so I could load it. I assumed that it would set it active but I guess I was wrong. Thank you for your help.

j2xu Posted June 14, 2006 Share Posted June 14, 2006 what exactly do you do to fix this issue? Link to comment https://www.insanelymac.com/forum/topic/19765-need-a-little-help-jas-1046-installs-but-does-not-boot/#findComment-129749 Share on other sites More sharing options...
Rammjet Posted June 14, 2006 Share Posted June 14, 2006 what exactly do you do to fix this issue? Boot using the install DVD and use terminal to use fdisk to set the partition active. Or find a bootable Windows or Linux Utilites CD/DVD and use the partitioning software to set the partition active. From another thread on using fdisk: - boot on DVD, open terminal - execute diskutil -list and keepnote of your HDD, mine is disk0, the mac os partition is diskos1 on my computer - execute fdisk on your disk + fdisk -e /dev/rdisk0 <-- use your disk number and note the added "r" + p (display partition) + f 1 (will flag the partition 1 as active) <-- use your partition number + write - reboot and it should be ok.

flipsoft Posted June 14, 2006 Author Share Posted June 14, 2006 I have not done this yet but I planned on doing the following 1. Boot to partition majic 2. Select drive 3. Make active 4. Reboot and see if it loads into 10.4.6 In my case the installation worked as planned but I guess the drive just did not get set to active.

Ok , I may be dense this early . But it's been awhile since I have been in the Terminal . I entered -diskutil-list , command not found . So how exactly do I enter all of this . Again sorry for the ignorance. EDIT: I have only disk0 , as I have no partition's . I have choosen only to run OSX , so no dual boot. I have skipped the first two , starting with fdisk-e/dev/rdisk0 I get "'no such file or directory" Running the JaS 10.4.6 install DVD.iso I have erased the drive prior to install , and used Disk Utility to use Journaled . So I am stuck atm.

chevy2410 Posted July 16, 2006 Share Posted July 16, 2006 I entered -diskutil-list , command not found . So how exactly do I enter all of this . Get rid of the dash before diskutil and put a space after diskutil and before the dash like this: "diskutil -list". Don't use the quotes either. Good luck, Chevy Link to comment https://www.insanelymac.com/forum/topic/19765-need-a-little-help-jas-1046-installs-but-does-not-boot/#findComment-145880 Share on other sites More sharing options...

Good luck, Chevy Thanks Chevy , RammJet has been helpful as welll . Here is what he recommended:- type: diskutil list (Note your HDD, mine is disk0, and the mac os partition may be diskos1) works - execute fdisk on your disk as follows: works EDIT: * type:fdisk -e /dev/rdisk0s1 <works * type: p (display partition) works * type: f 1 (will flag the partition 1 as active)works * type: w (writes change to disk) says it couldn't make it exclusive ? Seems like it was gonna work * type: q (quits) Link to comment https://www.insanelymac.com/forum/topic/19765-need-a-little-help-jas-1046-installs-but-does-not-boot/#findComment-145930 Share on other sites More sharing options...
Guinevere Posted July 17, 2006 Share Posted July 17, 2006 Hi All, I had the same b0 error, and used the diskutil as suggested. No more b0 error, however, when booting, I get Loading messages, then a blank screen. (the grey apple startup screen never shows) It then waits a few minutes, then reboots itself. I have read through the forums and this ATI video card is supposed to work. Any ideas? Thanks, Guinevere This is a Sony Vaio GRX P4 2.0Ghz (Northwood, I think) ATI Radeon Mobility 7500 1GB RAM Link to comment https://www.insanelymac.com/forum/topic/19765-need-a-little-help-jas-1046-installs-but-does-not-boot/#findComment-146382 Share on other sites More sharing options...
god-of-gamblers Posted July 20, 2006 Share Posted July 20, 2006 Just wanted thank RammJett for those directions! I had a great 10.4.6 install on my Acer 291 notebook, but couldn't boot up from the HD. Weirdly, I could boot from the install DVD, which would then load up the OS from the HD. But now I am great to go! Thanks!
