rkwok Posted June 30, 2006 Share Posted June 30, 2006 use fdisk to make your partition active, that's it. Link to comment https://www.insanelymac.com/forum/topic/20782-osx-will-not-boot/#findComment-137508 Share on other sites More sharing options...
Aqua Posted July 1, 2006 Share Posted July 1, 2006 I've been having the same problem. Could you (or anybody) tell me the command to set an active partition in Terminal? I've already tried using cfdisk on a linux live CD but it work with HFS.

Aqua Posted July 1, 2006 Share Posted July 1, 2006 Hmmm... It looks like it's an .exe file. I'm on OSX (my whole HD is dedicated to OSX). I don't have a floppy drive by the way.

Aqua Posted July 2, 2006 Share Posted July 2, 2006 Can anybody tell me of a live DVD of Linux that you think has an fdisk that'll let me set an HFS partition as active?

GeneralDelta Posted July 3, 2006 Share Posted July 3, 2006 I'm having the same b0 problem after installing 10.4.6 with the JaS DVD. The odd thing is that if I leave the DVD in the drive, and let it count down from eight and I don't do anything it'll boot! I would like to figure out how to get it to boot without having to leave the installation disc in the driver however. I'm not sure what you guys mean by using fdisk to set the partition active. Are you talking about the M$ DOS fdisk, of the OS X fdisk. I'm not sure how to get the OS X fdisk to do that. I run it as #fdisk dev/disk0s1 and it says the device is busy. To be honest I have never used the fdisk program supplied with OS X. So any help with that would be much appreciated! At this point I would like to point out that I'm not sure how the partition is not being set active. I install from the original 10.4.1, and used disk utility to partition and format my HD, and it booted fine. Not sure why all of a sudden 10.4.6's partition wouldn't be set active...

GeneralDelta Posted July 3, 2006 Share Posted July 3, 2006 Not sure if the above comment was directed at me or the guy who posted before me. If it was to me I think I was slightly misunderstood... I'm not running Windows... So no "Alchohol" (sic) or Nero. The only OS on the PC is OS X 10.4.6 at this point. Farther, I am a Mac user. I have a Dual G5, and a iBook G4, in addition to my Athlon 64 that I'm trying to get this to work on. (Just incase that's useful to know.) Not sure what you mean by "the emergency boot cd". The JaS install DVD boots just fine, and I can use the terminal from there if need be. Also as I stated above with the use of the JaS DVD I can get the installed OS on the HD to boot, it just won't boot independent of the DVD, just gives a b0 error. I also don't what this "boot mananger" (sic) thing is. Are there any commands that can be issued from the OS X terminal to clear this problem up? Thank you very much for you help and effort in this!

Blas Posted July 5, 2006 Share Posted July 5, 2006 GeneralDelta: What asap18 is try to say is that you should download 'Emergency Boot CD' and burn it to a cd, it´s doesn`t mathers if is with Alcohol... Nero... just with the soft that you use in your G5 (how lucky your are). This kind of soft has some tools to manage disk properties so you can use it to fix tha 'b0 error' Ok, i installed today the 'Jas 10.4.6 DVD' at my office and have this error. Apparently is caused because the unpatched intaller don´t ACTIVATE the partition (or the whole disk) and the system don´t know where to get the OSX. Now in my home I searched in the forum and all that we must do its to activate it. Here are the ways I found: + Use a Win98 boot floopy disk and use fdisk. + Boot whit a Linux cd. + Use an older MacOSX dvd like 10.4.4 (installation mode) and use the Disk Utility. + Use 10.4.x (installation mode) to set as the Boot Unity the disk (you can do it quicky entering the setup and qquiting, then the installer ask if you want to resart or set a Boot Disk) + Use 10.4.x and press F8 to have the entry mode and put: 'mount /Volumes/yourHardDiskName -setBoot' + Use a boot soft: spfdisk / Emergency Boot CD / Live CD Thats all i have... I could't test any of them because i need to wait until tomorrow to go to the office. Hope this help you. pd: the next time try searching in the forum, it´s the best and faster way to find this things. pd2: sorry about my english Link to comment https://www.insanelymac.com/forum/topic/20782-osx-will-not-boot/#findComment-139759 Share on other sites More sharing options...
GeneralDelta Posted July 7, 2006 Share Posted July 7, 2006 Thank you Blas for your reply! I have tried: Use an older MacOSX dvd like 10.4.4 (installation mode) and use the Disk Utility. (didn't work) Use 10.4.x (installation mode) to set as the Boot Unity the disk (you can do it quicky entering the setup and qquiting, then the installer ask if you want to resart or set a Boot Disk) (didn't work) Use 10.4.x and press F8 to have the entry mode and put: 'mount /Volumes/yourHardDiskName -setBoot' (didn't work) I have tried to use my SuSE 10.1 linux disc, and I don't see how to use it to set the partition active. I no longer have my Win98 CD, so I can't personally test that one. So I guess I'll have to look into the Emergency Boot CD method. Thank you so much for providing a link!!! I had no idea what he was talking about. Link to comment https://www.insanelymac.com/forum/topic/20782-osx-will-not-boot/#findComment-141175 Share on other sites More sharing options...
sandmanfvrga Posted July 7, 2006 Share Posted July 7, 2006 Ok, I got a Win98 Boot Floppy and My Windows 98 disc, just fdisk and make the main patition active? Awesome. I will have to try that. EDIT: Ok when I got to do dual boot, do I suspect the chain0 will be enough to boot OS X?
