The Dark Lord Posted March 26, 2009 Share Posted March 26, 2009 Rammjet, Thanks so much for the detailed explanation here. I just seem not to be able to resolve this. I am very new to MAC, but couldn't stand Windows anymore. I installed multiple different images on my Computer (Kalyway, iDeneb and other ones), which is a fairly new Sony Vaio, T9300 2.5 Ghz Core 2 Duo processor, 4 GB of RAM and all the other good stuff. I really just want to see if I like the OS. It has got to be better then F... Vista. If I do, the money is right there to buy a new MacBook Pro 17 inch man. I either get still the b0: error or I get a white screen. But it never boots up for me. I followed your steps and I went through them about ten times and it never booted up. What am I doing wrong. As said I followed your steps, verified that the correct disk is Active with a star next to it. It looks good at the beginning, but then it doesn't go. Is there anything else I might be missing? Thanks, I hope you can help me. The Dark Lord. There are a lot of people who experience a b0 error on their first boot up after installation.

SubCool Posted March 29, 2009 Share Posted March 29, 2009 Hey, i am having serious issues with this installation. I have made minimal progress. I somehow got past the Boot0: MBR etc. but I still run into my orignal problem. When my laptop loads, it stalls on boot. After running in verbose, i came across the same issue: Still waiting for root device. I am running this on my laptop. Single core, INtel, 1gb ram, 90gb HD, OSx86 10.5.6. I might run a ealier version, but i would liek to make it work. I am a noob- but i have tried most of steps on this thread, along with others. I have reformatted and primary partitioned the drive multiple times. There is only the primary HD in the computer. I havent been able to successfully boot into Mac yet. Any requests? im dieing to get this working. Link to comment Share on other sites More sharing options...
TBizzle Posted March 29, 2009 Share Posted March 29, 2009 So I have tried to search and search for an answer to the problem I am getting and I cannot find anything. Basically right after the install verifies that the install disk is stable to continue installation, it says that it cannot install folder: volume/leopardOSX/basesystem.pkg.157FJXMZe And like I mentioned I don't know what is happening because I cannot find in thing on it...

rsilves Posted May 21, 2009 Share Posted May 21, 2009 Hi. I am having a weird problem. I screwed up my MBR some months ago. After doing it, I tried many different methods of fixing it. Rewrote the MBR exactly how it is explained on this topic. Nothing helped. If I select the wrong partition, it shows that b0 error, but if I choose the one I think is right, it shows the blinking underscore with NO b0 error. This is the diskutil list output: /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *232.9 Gi disk0 1: EFI 200.0 Mi disk0s1 2: Apple_HFS Hackintosh 182.4 Gi disk0s2 3: Apple_HFS Backup 50.0 Gi disk0s3 (Only copied the code of my booting drive, the partition is Hackintosh. There are 3 more -no bootable- hard drives with different names). This is the print output after marking the partition active. #: id cyl hd sec - cyl hd sec [ start - size] ------------------------------------------------------------------------ 1: EE 1023 254 63 - 1023 254 63 [ 1 - 488397167] <Unknown ID> 2: 00 0 0 0 - 0 0 0 [ 0 - 0] unused *3: 00 0 0 0 - 0 0 0 [ 0 - 0] unused 4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused This also happened with a friend's hackintosh. Different haraware, different install DVD (mine was Kaly 10.5.0 and hers Kaly 10.5.2). But it was different, she had the b0 error from the first boot. I tried choosing all of them with no results. Always type rdisk. ---------- Now (30 seconds ago) I noticed that if I reopen fdisk and use the print command (p), the partition table doesn't have an asterisk on it (having marked it active 30 more seconds ago). Shouldn't it show the asterisk now?! When I leave the Install DVD inside, the system boots normally. I was going to leave it like this until next major update, but now I want to test kernels, and for doing that I need to use the Darwin Bootloader, which doesn't appear when loading from DVD. Also, there is an issue with my DVD drive, and if I forget a DVD inside it (mounted), Mac will try to send it to sleep after 15 mins and it gets stuck until next restart. So these are my reasons for trying to make it work. I hope you can help me. I read before that a user used Windows to mark the Mac partition active. Can I do this? (I have a spare drive with Windows XP on it, not plugged now). Thanks, Rodrigo Link to comment Share on other sites More sharing options...
CreedMac Posted May 31, 2009 Share Posted May 31, 2009 Hello, I'm installing Kalyway 10.5.1 to my external HD which is called Kebab. When I boot, I always get the b0 error which I've googled and the most topics say that I gotta set it to "Active".. The external HD has got 2 different partitions, one is called MAC and the other one is called DOCUMENTS. The single external HD's "number ID" is called disk6. I wrote the "p" command and I don't know which to choose and I don't wanna choose my system which I think is called disk0.. Please help! EDIT: The external HD is 500 GB splitted on two partitions please HELP! I don't want to loose my windows system.. Link to comment Share on other sites More sharing options...
noobatlife Posted July 13, 2009 Share Posted July 13, 2009 Hey Rammjet, sorry I'm a few years late lol, but I followed your directions and I need help. Of course, my game is a bit different - I'm using iATKOS v7 and the Terminal is something called bash-3.2 Anyways, I use "diskutil list" and it's evident my partition is on disk0, so I follow the next step, typing in "fdisk -e /dev/rdisk0". As soon as I press enter, all that comes up is "Enter 'help' for information', and the line begins with 'fdisk: 1>" I am so confused... I hope this isn't a problem with the version. Please help!

steli0s Posted September 7, 2009 Share Posted September 7, 2009 First of all, respect guys for this great forum. I'm new to the osx86 stuff, i installed leopard 10.5.7 using iATKOS v7 DVD. Everything went fine, but i had a flashing cursor. I used the following advice to fix the flashing cursor: http://apple2pc.blogspot.com/2008/04/blink...86-install.html and after that i had the boot0: done boot0: MBR problem like other users. I tried exactly what the first post said and still it can't be fixed. I only have one hdd mounted atm, with only one partition where i installed leopard. i'm posting some screenshots and let me know if i'm doing something wrong please... As you can see, here's exactly what i wrote: diskutil list fdisk -e /dev/rdisk0 p f 1 write yes exit what am i doing wrong here? i remove the install dvd, reboot and same thing happens...

JavaKrypt Posted September 27, 2009 Share Posted September 27, 2009 Hey. I know how to install MacOS and XP dual-booted. I've done it many times. But I already had Windows installed and so I went ahead and installed MacOS afterwards. It's installed fine (the files) but I can't boot it. When the computer turns on it goes straight to Windows XP. Now I've already known about using fdisk, I've tried it millions of times but it wont do anything. It keeps booting my Windows partition first every time. I haven't even managed to install my user account on MacOS because I can't boot it! I was getting the boot0 error, but I know that was an error on my behalf. What do I do? I don't fancy installing it all again with Mac as s1 because it was a failed Snow Leopard upgrade that fudged this up and I haven't got any idea how to backup, then restore XP if it fails (I've tried Ghost and stuff before, I don't like it. I prefer Disk Utility using Restore. But I can't do it with the install disk because it can't recognize it.) Link to comment Share on other sites More sharing options...
pointblankshotx Posted October 18, 2009 Share Posted October 18, 2009 Okay everyone i think i sorta got a solution here, im not any sort of expert but i got it working through trial/error. i am dual booting iatkos v7 and windows 7 on a dell inspiron 1521 amd. i installed iatkosv7 then installed windows 7 and was stuck only loading windows 7. i could boot osx but i had to boot from cd and couldn't get a wifi connection for some reason. so i followed the guide in this thread and got stuck at the blinking cursor screen or the mission operating system screen (depending on which partition i made active with the guide posted). After a few days of googling and searching around i just figured id get creative. So, i loaded up my iatkos v. 7 install dvd and under "utilities" there an option "Chameleon v.2 installer" so i ran the installer, followed the instructions and got the chameleon screen to boot instead of the blinking cursor. But first go to utilities>disk utility select your mac partition and Unmount it. then close disk utility now open up chameleon v2 installer wait a few seconds for the scripts to load It will prompt you to do several things, i believe the first one is: select disk (for me it was 0) Type: 0 (or your selected disk) then press enter Type: Y DO NOT PRESS ENTER, by pressing y it automatically enters it for you. now you will be prompted to enter partition number i selected 2 because thats where my osx is installed. (why i selected this one i have no idea, but it worked) so type 2 or whatever number you want to install it to. press enter then type: Y again, AGAIN DO NOT PRESS ENTER after this just follow the instructions and keep pressing Y. until it says "proccess complete" or something like that. Now close the terminal and quit the OsX installer. a window will pop up that has a Restart button. push it. now you should get the chameleon screen again. The first time i selected my mac harddrive from the chameleon screen, it timed out and restarted. chameleon popped up again so i tried windows and i got some sort of hardware failure BUT the third time i restarted i selected my mac partition again and it loaded fine! however it was really weird and buggy, i could not select the little apple logo to restart or shutdown, the top bar would disappear every time and finder would reload... this is a different issue though i think. -i just restarted again and i can click the little apple... maybe the more i restart the more efficient it runs? everything seems to be working fine now except i get an error when trying to load windows. "Status: 0xc000000e Info: the boot selection ailed because a required device is inaccessible" im going to try to repair this so we'll see what happens. so try this, at your own risk obviously and let me know how it works for you. ~pointblankshotx Link to comment Share on other sites More sharing options...
eolithix Posted November 13, 2009 Share Posted November 13, 2009 ok I've had the boot0: error I se the right partition active and then ofc boot0: done (and nothing happens) I tried to install chameleon 2 as "pointblankshotx" mentioned but still didn't work so I guess we wait for other suggestions :/ Link to comment Share on other sites More sharing options...

helob Posted December 2, 2009 Share Posted December 2, 2009 Need your help and advise. I am running SL 10.6.2 and boot using Chameleon v2 rc3 from a seperate partition "Cham" on same HD with 5 partitions (See Attachment). Now booting from Cham some times encountered KP ( blue or black screen just before booting into SL) Problem: diskutil list shown a total of 5 partitions including EFI With fdisk -e /dev/rdisk0 and p, Only partition 1 is shown with unknown id. (See attachment) Rest of partitions shown unused. So can't set my "cham" partition active. I must have screwed something up. What must I do to correct the problem so the proper partitons is shown in fdisk?. Does the command "fdisk -u /dev/rdisk0" help to solve above the problem? I like to get feedbacks from anyone who has tried repair MBR with this command. TQ Link to comment Share on other sites More sharing options...
