Ibook won't boot completely ! (stops at a blue screen)

Hi...first time poster here, please be kind. Also, I'm not brilliant by any measure when it to computers.
Yesterday I was installing updates (now, my ibook was out of use for at least 8 months, so I was bit back logged on updates) and after the second round (a safari update, a java update, and a security update) it said it needed to restart. Ok, easy enough, though apparently not it never booted up again. I get past the grey apple loading screen and to the blue screen that says "loading os x"...the progress bar finishes and then it disappears and all I get is a blue screen with a rotating "busy/working" symbol. A few times I got a black screen with white text asking for my login and password, but it always says it's wrong or it won't even let me type in a password before it freezes and goes on to the blue blank screen again. I did a PRAM cleaning and that ran correctly but did not help. It will not load in safe or verbose mode. Any one have any idea why my ibook is doing this or if there is anyway to fix it ? (also, I'm not sure eaxactly which os X I am running other than it os x 10.4) Help...

If you can't find the system discs that came with your computer, use fsck (a command-line utility that may be able to verify and repair a disk)
To use fsck:
1. Start up your computer in single-user mode to reach the command line.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

T410 Won't Boot/Recognize HD After a Blue Screen

Hello, Few days ago, while i have been installing partition magic (during the install - preior to using the utility) i got a blue screen that repeated itself everytime i tried to boot. I have used a utility that comes with windows 7 boot disc, that tried to solve "boot problem". eventually i did not get a blue screen anymore - though now i can't find the HD in the HDs list. I tryied To Run HD Test from the BIOS but it took an hour and it still was 0%. Is that enough to determine my HD is gone? or is there still a way to revive it?(I dont need to restore all the data, i just want to be able to install windows on it) Any ideas? Thanks.

Hi, When Windows won't recognize a disk, I sometimes use a Linux based OS to identify and format disk, since it sometimes is a bit more "don't care" mode than windows utilities. You could try to run "Ubuntu Live" from a bootable USB:http://www.ubuntu.com/download/desktop/try-ubuntu-before-you-install 1. Download the ISO:http://www.ubuntu.com/download/desktop 2. Install the ISO on an USB:https://rufus.akeo.ie/ 3. Boot from USB: When your PC starts, Press F12 and choose the USB you just made bootable in step 2. 4. Use the "Try Ubuntu" utility 5. Open the program: gparted (a disk partition program) 6. See if it can find the HDD, and if it can, try to delete all partitions. Edit: Apply the deletion and then shutdown, and try to install windows again with recovery cds or iso image.

MacBook Pro won't boot (question mark folder) after blue screen on windows bootcamp

Hi,
So, I was on windows, using bootcamp, and I was creating partitions on a pen drive with it, and then it asks me that it needs to restart to apply changes.
But then, while restarting, a blue screen occurred (**** windows).... And I forced the shutdown pressing the power key.
Then, I simply turned the MacBook on, trying to boot on my snow leopard and I got a flashing folder with a question mark on it.
Now I can't access any partitions on it, if I press option key on startup I get a blank window!
I tried to reset PRAM, repair the MacOs partition using the snow leopard DVD (it shows up fine, along with windows partition and EFI partition), and I still don't get my startup disk showing up...
How can I fix this? I can't loose my files and I need to work with it :/

I just fixed it!
For future reference, what I did was:
- Booting from OSX DVD, go to disk utility
- Erase windows partition (yap, I lost it...)
- Do a "repair disk" on every partition of my hard drive
- Restart
And it just worked ;)
Thankfully I had no important files on my windows partition, now I will just reinstall it.

IBook won't boot from CD

I bought this iBook, used, with Tiger on it. A while back, it had Debian Lenny installed onto it. Now I can't reinstall Tiger...
I have tried holding "C" before the gray screen when it boots, and I've tried holding "option". It only shows the disk with the Linux penguin, but not my Tiger install CD. Holding C, it only loops trying to read the CD; it does NOT reboot, it just unsuccessfully continues attempting to read the disk.
I know it not be a problem with my CD, because I can't reinstall Debian or Kubuntu or Ubuntu, even from the disk used in the past. I have tried resetting the PRAM and PMU..
Is there any hope?? I'm done with using Linux.

Yes, the iMac will still boot from the CD. The iBook won't boot from any disk anymore, not even retail Panther. I know that the CD drive still works, because I'm using it right now to listen to music in Debian.. I think something's up with the open firmware, and I should update it but that can only be done through Classic right? There's not even an update for my iBook, I think.
I've tried burning several different linix distros, and they all work with my iMac but not iBook.
And, yes, it is a set of four CDs for Tiger.

this usually means the software and hardware can't find each other for whatever reason the following article addresses this issue:
http://support.apple.com/kb/TS1440
can also do apple hardware test, following article on that:
http://support.apple.com/kb/HT1509
if you can't access the apple hardware test in the above article you can also do fsck command to check the hardware as well, following article tells how to do that:

hopefully one of these articles helps w/ resolution!!

Many times I tried to simply update from 10.5.8 without any success. It starts and after few minutes ...
I used many different install disks (I bought ofiicial release from Mac seller), so I think this is not a problem with wrong version or bad install disk. A few days ago I've got back my computer from Apple technical support and technician told me he had this same problem with system installation

HP G7000 G7096EA Won't boot, no post/bios, blank grey screen

My HP G7000 G7096EA Won't boot, no post/bios, blank grey screen - It does appear to get into windows after return is pressed, albeit with blank grey screen.
I've reseated the RAM/harddisk, tried the power button reset method. Left it overnight with power battery/power.
I'm at a loss now with what to try. It does look to be a dead graphics chip, which is a shame and will probably put me off HP for life!

Ok, I've stripped it down to diagnose. Due to the piss poor cooling on the graphics chip, it's fried itself and melted the solder underneath.
This was actually the second laptop I had off HP as the first broke within a very short time.
Needless to say, I'll be buying from Dell in the future! What a crock of **bleep** HP are.
Oh yeah! And HP wanted £16 + vat just to speak to some outsourced crappy call centre!

HT1752 my powerbook g4 will not boot up. i get a blue screen. i have tried to start up in safe mode, but get the same blue screen.

My Powerbook G4 (with Snow Leopard operating system) will not boot up, I get a blue screen. I have tried to start up in safe mode by holding down shift key after startup tone, but end up with same result...blue screen. I need important photos and documents of this laptop, Even if I can just get it started up one more time. Need help fast! If you know what to do, please message back.

In the text you say you are using Snow Leopard. Snow Leopard will not operate on a G4 (or any Mac with a PowerPC processor). Leopard OS 10.5 is the max OS for PowerPC processor Macs. Your profile shows OS 10.5.6. What OS are you using (or trying to use)?

HELP PLEASE!! Boot problems with Snow Leopard (Blue Screen Loop)

Hi guys!
My MacBook (the model before the current one) wont boot up. It started stuttering and acting strange and then froze so I did a force restart. It then loaded all the way up until a blue screen when the mouse appears and can be moved. This flickers off after a few moments (the screen dims) and then comes back. The process repeats as if in some infinite loop.
The main problem is that I've lost my snow leopard disc so I'm pretty limited to what I can do until I can borrow / buy another one and I need to get my laptop back up right away for work.
I've tried booting in safe mode, no joy
I then tried to repair the drive in fsck, which repaired something. I did it again and it said all was ok but then booting stuck at the same place.
Finally I read on another forum that removing /Library/Preferences/com.apple.security.plist fixed login loop issues. I attempted this in single user mode but it said the file didnt exist?
Can anyone help me out here? I'm pretty stressed out as all my work stuff is on there for my new job...
Thanks!!

I had this same problem -- machine would boot, but loop at two blue screens before the login window. I sshed into the machine and checked /private/var/log/system.log and /var/log/secure.log which showed a unexpected character in /etc/authorization. Basically, the authorization file was corrupted (most likely by bad RAM.) The solution was to replace this file with one copied from another machine. I didn't match models, but did match OS when copying the file (i don't know if this matters at all), and as soon as the "cp" command was entered, the login window popped up. <-- totes awesome. The machine has been reliable since (all of 15 minutes)

Try resetting the SMC

If it has a removable battery, try removing the battery.
If neither works, then you may need to bring it in for service. Bring the power adapter as well, as you may be able to determine if it is the power adapter at fault, or the computer's power supply.

IBook won't boot, stops at gray screen--HELP

I couldn't find this exact topic at first glance and I am hoping someone can help me. My ibook is about 5 years old and has only really crashed on my once 2 years ago but I was able to reinstall the OS and go on my way. This time, however, nothing works. I tried to boot up yesterday and the gray screen appeared and that was it along with a strange buzzing sound. I tried Disk Warrior, wouldn't even boot off that. Also tried booting off system disk 1 and didn't get past the language screen, just hung up with that buzz again.
Does this sound like a logic board issue? Can it be rescued?
Thanks in advance for any help!

I'm not sure if the computer can be checked out at home in such a way
in its present state, to see if there is a logic board failure behind it, now,
or not. There could be a hard disk drive failure, or ATA controller failure;
and a short list of other possibilities, best checked over by a specialist.
Certain keyboard commands and things could be tried (and I usually
assume they'd been tried before asking here, but that's often not so)
just to see if one or more of them could get a rise out of the dead Mac.
Be sure, if you can get the installer disc to boot the Mac, that you
try and use the Disk Utility to repair disc; maybe more than once;
and do not try to just reinstall an Archive and Install. The HDD may
have corruption issues and it may need low-level zero-data and re-
formatting before a new system could go on there, if it worked at all.
{Even trying to reset PRAM/NVRAM and then seeing if you can get
the bootable OSX installer disc to start up the Mac could be OK.
Maybe that PMU reset, as a last resort? It probably won't hurt...}
A system on an external bootable enclosed hard disk drive could be
used by a tech or a prepared home-tech owner, and a clone of the
machine's system then attempted to be used to boot the ailing Mac.
If the optical drive and other components relying on the logic board
are dysfunctional due to a defect on that main board, most external
devices may also have a hard time trying to use these methods of
outside efforts to troubleshoot be nominally successful.
There may be a way a tech can use an second computer to get
data off the drive in your iBook, should it come to that, by using
the FireWire Target Disk mode and see if your iBook can start
and act like an external hard disk drive. A copy of the drive's
content or parts of it may be made by the second healthy Mac.
A clone (perhaps not bootable if data on it is damaged and not
recoverable) could be made if the second healthy computer has
a clone utility and also an external drive it can copy/clone the
iBook's drive content over to. This may be asking too much;
but the home user who has stuff on hand could do it shortly.
Anyway, there are some ideas online, if you can search google
and choose appropriate words; I looked but you may need to
read through several different source links to see if anything
sounds like it may work. re: iBook won't start past grey screen
Some users have tried resetting the PMU, others tried NVRAM
and PRAM; a few tried SafeBoot to see if the system was OK
enough to load in a reduced startup mode; maybe where the
system's own Disk Utility could be ran to at least fix permissions.
And of these, if it is truly a logic board or a failed hard disk drive,
they won't really do much. Probably no harm; and that is part
of what troubleshooting is all about, working with zeros and ones!
Good luck & happy computing!

Clamshell iBook Won't Boot from Jaguar CD (v10.2.3)

Branching off from a prior thread (https://discussions.apple.com/message/13222609#13222609) in which booting from an OS X CD was a potential solution to a problem, the problem encountered with the potential solution warrants its own thread.
My machine is a Clamshell iBook (G3), Revision B (with 64MB base RAM and no FireWire). It was purchased new eleven years ago and later ugpraded to 192MB RAM.
The OS on the hard drive was 9.0.2 until yesterday, when I updated it to 9.1 so I could bring the firmware up to date. I did this before attempting to use the Jaguar CD.
The CD in question is an original Jaguar install CD, version 10.2.3. This is a two-disc set (the discs are labeled 1 and 2) and is a retail version; my iBook was manufactured prior to the release of OS X (non-server) and does not have an OEM OS X disc.
When the iBook attempts to boot from the CD, either by pressing "C" at startup or by running the Installer from OS 9.1, it seems to be loading fine until the following appears:
At this point, the iBook won't load any further and a restart is required.
The iBook does boot an OS X Cheetah (10.0) CD as well as its own restore disc (9.0.2) and the 9.1 disc that came with Cheetah. Unfortunately, Cheetah doesn't seem to have any effect on the battery (this is why I'm booting with an OS X CD; see the posts in the other thread for details). I don't have any other retail CD versions of OS X to try (aside from a Snow Leopard DVD).
Aside from this boot problem and the battery issue (the computer won't recognize the battery and displays an "X" through it even after having charged it with an external charger) the iBook is working perfectly fine.

No. I get the "X" through the battery in the menu bar and no bars, just a plug icon, in the control strip under OS 9.
The battery is a year old and has never been recognized by this computer. I don't have another Clamshell to test it in but did verify that it can charge in a VST charger.
The last time the computer recognized a battery was about 6 years ago when the initial batteries were still in use. Both were completely depleted after my charger shorted out; they didn't charge again after I got a new charger. The batteries were healthy at the time and were able to hold 3-4 hours, which was pretty typical mileage for me on this laptop.

Ibook won't boot up on own or from OS installation CD (need help in Yemen)

Hello,
I'm currently in Yemen for a few months and my ibook seems to have died on me. The country isn't exactly brimming with Apple support technicians so any advice or suggestions people could give me would be really appreciated.
I have an older ibook (dual USB G3 which I bought in June 2001). It has the occasional application or OS freezes, but typically restarting solves these. Yesterday, however, when I tried restarting the computer wouldn't boot up - it would get to the gray start up screen with the apple and spinning wheel and would just sit there with no progress even after an hour. I removed the airport card and extra RAM, but no luck.
I ran the Apple Hardware Check CD, but everything came up clean. I also ran Norton Utilities Disk Warrier and it found Major Errors in some of the directories (I have the list at home if that would help) all of which it said it fixed. However, it wasn't able to complete checking the HD, at one point it tried to find some files and never was able to get any further in the check - it would just sit for hours with no progress. When I tried rebooting the computer on its own it got no further than a gray screen.
At this point I decided it might be easiest just to reinstall the opperating system. I put in the installation disks (OS 10.2.4) and tried booting up from the CD - the boot up was very slow and ultimately (maybe after 10 minutes) instead of a gray screen with an Apple logo it came up with the "forbidden symbol" (i.e. the circle with the slash through it that you see on no smoking signs).
At this point I'm not quite sure what to since it isn't booting up from the installation CD - are there any other tricks I could try or reason why it won't boot up from the CD? I also have a copy of 10.4 installation CD but I'm hesitant to install it just because the ibook is such an old computer and it would require the extra RAM to run it (currently I have 300 something of RAM in the computer). I also have a 20 GB external harddrive with me if there's anyway I could boot up with it.
Three years ago the laptop had major problems and basically died, but went into Apple and seemed to have been fixed and had the logic board replaced. After this point I got a new laptop (which I'm hiting myself for not bringing with me at this point) and haven't really used this computer frequently - maybe 5 to 10 times in the last 3 years, it really is a "spare" laptop. I used it for about a week before coming and it seemed to be working fine.
At this point I'm really open to any suggestions on how to fix and jury rig it to work for the next 3 months (really I just need to be able to use Word and iPhoto) or so as I won't be using it once I get back to the States. Any suggestions or help would be greatly appreciate. Thank you very much!!

Hi, and welcome to Apple Discussions.
Which utility did you use on the iBook? Was it Norton DiskDoctor or Alsoft's DiskWarrior? They are two entirely different things.
Norton DiskDoctor was developed for OS 9. It doesn't recognize OS X as a legitimate operating system, identifies OS X as "errors" on your drive, and sets about "fixing" those errors, really messing things up in the process. (It does this even if you run it in OS 9 on a drive that has OS X on it.)
Apple calls the sign you are seeing when trying to boot from the CD a "prohibitory sign."
Check out this Apple Knowledge Base article on what to do about a prohibitory sign at startup:
http://docs.info.apple.com/article.html?artnum=106805
Maybe something there will help.

Help! iBook won't boot up after latest security upgrade....................

I have an iBook G4 12 inch screen mac. I have recently updated with the latest Apple security update (15/9/08)Since installing the update my iBook has failed to boot up successfully. There is no start-up chime and the boot stops at the grey screen with the Apple logo and goes no further. I have tried safe mode, won't go there, have tried various other tips, holding down various keys on start-up, all with no joy! Does anyone have the same problem and does anyone have any answers?! Thanks in advance!
Jim

Thanks, Cornelius. I am just afraid now, is it safe or should I forget about reinstalling the most recent update? It is moot right now though anyway, because I still can't get my computer to fully boot up. At least attempting to book with the OS 10.5 disc in the drive it does not power down, but it is getting stuck for a long time (over 30 minutes) on the gray startup screen with the apple and the DVD drive repeatedly spins and stops, then finally just seems to stop spinning and gives up.
