No password, not booting from CD

I got a used iBook yesterday. It is booting only in safe mode, and no matter what I try (holding down C key, holding down shift) it will only boot up in safe mode with the previous owner's log in screen. They don't remember their password, and its not booting from the disc. I think I'm missing something pretty simple here...

Congratulations!
Are you now able to boot from the Installation disc? (You may need to be able to do that in the future.)

Reset Password - System does not boot from DVD

My System: Macbook Pro - 2Ghz Intel Core Duo - OS X - 10.6.8
Hi everyone,
i forgot my password. So i want to boot from install DVD to reset the password. Unfortunately my macbook pro does not boot from DVD (10.6.3).
I press c all the time...but sometimes the macbook pro throws the DVD out...and sometimes nothing happens.
The DVD drive is working fine...
Any other idea?
Thanks in advance.
Fabian

So when you boot holding option it shows a padlock with a password field? Is that correct?
In that case we're talking about the firmware password, which you can't reset via the install disk. There is only one way to do this, I'm not certain if one is allowed to divulge that information publicly - might want to try googling "reset firmware password"

Hard disk not recognised - will not boot from cd & No FW Target Disk mode

hi,
some help would be greatly appreciated.
Some time ago i was switching internal hard drives around and wound up with a kernel panic of some sort (see my previous posts).
following on from this I have tried FW target disk mode with no success, and it will not boot from a retail Tiger install disc (this machine has tiger installed (i think!). I can't force a boot from the optical drive and i also can't even force it to eject the disc inside to try another install DVD/CD (I have panther discs lying around also).
when i start up with the c key nothing happens, but when i start up with the alt/option key i get a closed padlock symbol, password entry field and a "right facing arrow" button.
anyone got any clues with this? i'm guessing it could either and/or be an internal hard drive ribbon failure (i have swapped internal HDs multiple times in this machine, which can't be good for it) or the familiar PRAM problem (although why would it not boot from an install DVD if this was the case?). I have changed the power supply unit in the past due to having a power cable snap off inside the original one - damage to PRAM caused by this?
help would be muchly appreciated!

Hi, Jesse. Remove the hard drive and its cable, then see whether you can start up from a CD or DVD. If that works, replace your hard drive cable.

Imac Not Booting From CD

I've tried just about everything at this stage, so I'm here asking for help. I have an Imac, of which I can log into the root account and has no openfirmware password. The Macos ISO is seen from within Macosx, though I cannot get it to boot from cd, whether holding down the "c" key or setting that device to boot up first from the startup disk menu. I have tried resetting the pram and nvram and reset-all within openfirmware, and the "boot-device" command within openfirmware shows exactly the same as another machine which does boot from cd. I know that both the drive and (multiple) CD's I've tried are functional.
Can anyone point me in the right direction as I am at a loss at the moment and have no further idea's of my own.

n0der,Welcome to Apple Discussions.
Is the Optical drive known good? can you read other disks?
If not do you have another Mac you could use Target Disk Mode on and hence use that Mac's optical drive rather than the iMac's internal...
Does Apple Hardware Test CD report any faults or will it not boot from that either?

Not booting from 10.4.8 volumes after upgrade from 10.4.7

I'm sorry to report that my aged G4 450 MHz AGP with 4 internal Hard disk drives no longer boots from any of the 2 volumes upgraded to Mac OS X 10.4.8 as soon as it was started from another volume!
All was working fine as long as 10.4.7 was installed on the 2 232 GB disks connected to the SIIG ATA133 controller. I could boot from any OS on any of the 4 disks, 5 partitions:
internal ATA66 bus:
18 GB disk, 2 partitions: 'IBM_18GB' with OS 9.2.2 and TechTool Pro's 'eDrive' with 10.4.7
71 GB disk, 1 partition 'IBM_71GB' with OS 9.2.2
PCI SIIG ATA133 controller:
232 GB disk, one partition 'I1232GB' with 10.4.7, now upgraded to 10.4.8 and no longer bootable
232 GB disk, one partition 'I2232GB' with 10.4.7, now upgraded to 10.4.8 and no longer bootable
Now I can only boot from the Mac OS 9.2.2 or the eDrive 10.4.7 partitions.
What I did so far: 'I2232GB' was my main OS X startup volume, 'I1232GB' contains a clone of it, plus additional folders like software base and backups.
After upgrading 'I2232GB' to Mac OS X 10.4.8 through Software Update and repairing permissions all was OK as long as the Mac was just shut down or re-started: it always booted up in Mac OS X 10.4.8 from 'I2232GB' without any problems.
The next day I booted from 'I1232GB' to do the same there.
Afterwards I could no longer boot in Mac OS X 10.4.8 from 'I2232GB' nor in in Mac OS X 10.4.8 from 'I1232GB': it just gets to the grey screen with the Apple logo, but the round circle underneath indicating some progress never appears. I left it there for hours: it just hangs.
With the Option key held at startup I could boot from the other partitions with Mac OS 9.2.2 or the eDrive with 10.4.7. None of their Startup Control Panels was able to get me back to 10.2.8!
So I booted from the TechTool Pro 4.5.1 DVD to Optimize both volumes, 'I1232GB' & 'I2232GB', always Files only.
Then I booted from the DiskWorrior 3.0.3 CD to rebuild the directories of both volumes, 'I1232GB' & 'I2232GB'.
Still I can not boot from either 'I1232GB' or 'I2232GB' in Mac OS X 10.2.8!
Downloaded the Mac OS X 10.2.8 Compo Update (for PPC) and installed it onto both 'I1232GB' & 'I2232GB' while booted from the eDrive which I keep on Mac OS X 10.4.7 - no luck either, still I can not boot from either 'I1232GB' or 'I2232GB' in Mac OS X 10.2.8!
Then I backed up the users folder from 'I2232GB' onto 'I1232GB', booted from Mac OS 9.2.2 and used Intech's Hard Disk Speedtools 3.6 to format 'I2232GB', afterwards initialized it with Alsoft's Plus Maximizer Extension for a Block Size of 512 Bytes.
Installed Mac OS X 10.4 from DVD, as well as iLive '06 and upgraded everything to the latest releases with Software Update. All was working fine with all the required reboots until another startup volume was chosen: afterwards again I can no longer boot back into Mac OS X 10.2.8 on the fresch installed 'I2232GB'!
Any help would be appreciated.

Apple G4 AGP Mac OS X (10.4.8) 4 internal hard disks, dual layer DVD-RW, 2GB RAM

What I did so far: 'I2232GB' was my main OS X

I found several typos in above post, wherever it was 10.2.8 it should have read 10.4.8 - I'm very sorry for confusing you, this would not have made sense, but I found no way to edit the existing text therefore I modified the quote of it here.
I do not need Mac OS X 10.2.8 back, but it would be nice to boot back in Mac OS X 10.4.8 from another volume as the current one - which was working fine before with Mac OS X 10.4.7.
Many thanks,

Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
So to sum up, the symptoms I'm seeing:
MacBook Pro CAN see internal SATA hard drives.
MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

UPDATE: An interesting development!
I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
Onward!

Will Not Boot from Install Disc & 4SNS/1/40000000: TG0D - Thermal Sensor?

*Will Not Boot from Install Disc*
I used the "option key" approach with the gray start up disk. At first it ejected the start up disk. Then I nudged the disk back in the machine and it showed on the screen as an option. I clicked on the start up disk image and it finally loaded.
But, it won't accept the start up disk when holding down the "C" key at restart.
*4SNS/1/40000000: TG0D*
I did an Apple Hardware Test and received the following diagnostic:
Version: 3A121
Test Suite: Extended Test
Loop Count: 2
Result: Failed
Failure code: 4SNS/1/40000000: TG0D
*Thermal Sensor*
A search for the failure code 4SNS/1/40000000: TG0D brought up an Apple Discussion topic entry stating: That error code indicates a problem with a thermal sensor. It could be not working or possibly not connected. You will need to take it to Apple for repair.
Would a thermal sensor have anything to do with it not starting up when holding down the "C" key at restart? What are thermal sensor problem symptoms?
*User File Folder Opened Up*
The machine also starts up with my user file folder opened up rather than with a blank screen as it normally should
I completed a DiskWarrior rebuild on the disk and verify disk shows it is fine.
Any suggestions on what to do next with these issues?

The answer was in your post: "You will need to take it to Apple for repair."

Can not boot from OSX disc

I recently partitioned my internal drive with an 80 gig partition to run Ubuntu , removed Ubuntu and now can not resize hd to recover the 80 gig that I used , there was a program with this Ubuntu install called rEFIt that was installed for the dual boot , My problem is that Itunes keeps crashing and I have spent somewhere around 8 hours trying to fix this issue and in the process I discovered that I now can not boot from the osx disc but I can boot from the Ubuntu disc , what can I do to correct this issue or is there anything that I can do to correct this and recover the 80 gig that I used ?

The only solution was to erase hd and restore from time machine backup......
According to everything that I have seen , read and tried when you partition the mac hd the way that mac is designed it will lock the hd thus preventing any access even using the startup disc to repair. As far as restoring everything after the erase and reinstall of the OSX that was easy and painless. FOR ANYONE WHO DOES NOT BACKUP THEIR DATA THIS IS WHY YOU SHOULD!!!!
Once OSX is reinstalled the migration assistant will ask if you want to restore from a backup , if you have time machine or any other sort of backup simply choose the one you wish to restore from and continue , must admit I was a bit hesitant at first , I must say that everything restored with the exception of some settings that I have had to restore but they were not major settings , after the backup is restored simply run update check and reinstall all updates , may need to do this a couple of times.
Depending on the amount of data you have will determine the length of time for restore (500 gigs about 6 hrs.) but it will restore user account settings , connection settings and network settings.
Hope this will help if anyone has experienced the same problem.

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

IMac will not boot from any mode except Target Disk

I have an Early 2008 Penryn iMac 24" MB398LL/A running OS X 10.7.4 (see specs below) that will not boot from ANY mode, It also has several strange vertical bars from top to bottom on the screen. They are about 10 px wide, with some pixels empty and looks a bit like a barcode if you squint at it.
I have tried Safe Boot, Force Boot, DVD Boot, FireWire/USB Boot, and it always gets to the same point. It gets to the apple screen with the spinning gear and then after about 8 seconds it freezes. The only way it works at all is in Target Disk Mode. It pops right up on my Macbook Pro and I was able to grab all my info!
I have run Disc Utilities and Tech Tool on it many times from my MBP and it passes every test.
I reformatted the HD and installed 10.7 again, it still freezes up at the same point.
I have tried using Single User mode and every time have had to run /sbin/fsck -fy twice because it always says the disk is ok but it was modified on the first pass.
I thought maybe it had a bad video card or logic board but and I ran the Apple Hardware Test on many occasions and it always passes. Recently I was told about Loop Mode and just completed running the AHT for just over 30 hours without any errors at all.
UPDATE...
Strange Part… I tried installing Mountain Lion in Target Disk Mode and everything went smoothly. When it restarted on its own the lines on the screen were gone for the moment, but the Mac still freezes up on the spinning gear and immediately restarts on its own. I have run every thing listed above on it and still nothing. Sometimes the lines reappear then in two more starts they are gone.
I did manage to have it start one time got a copy of the the error report (its at the bottom too) The Mac ran for at least 30 minutes with no problems, then the screen went crazy a few seconds and it became unresponsive. The mouse moved but that was all it could do. Now my iMac continually restarts itself, I don't have any more ideas, HELP!

RE: HP XP Media Center 2005 Ed will not boot from HP System Restore CD's

RE: HP XP Media Center 2005 Ed will not boot from HP System Restore CD's.
The following instructions about the "Code Purple" error FAILED. Error is still present.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
***PLAIN ENGLISH QUICK AND EASY FIX FOR ALL SYSTEMS****
***Windows 7 code purple or Windows Vista code purple***
With the code purple error on the screen, press shift+f10 (the shift key and the F10 key (at the top of the keyboard) at the same time) to open a little screen called a command prompt. (So, you get a little black screen with white text that says something about your Windows verison first and a little ways down you'll see "C:\>".   It's all ready for you to start typing.)
Type the following line, just as you see it here...
notepad C:\hp\bin\checkdmi\checkdmi.cmd
so it will look like this
C:\>notepad C:\hp\bin\checkdmi\checkdmi.cmd
Press Enter.
You will see the text for the file listed in a window using a simple text editor.
Go to the beginning of the text. Press enter to make a space. Type this...
goto cleanup
So, whatever comes after, the first line looks like this...
goto cleanup
Save the file and exit notepad and restart your PC. You are good to go.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RESULT: Same error and problem.
So, NOW THE SCENARIO IS THIS...[ And A CHALLANGE TO ALL HP Software EXPERTS]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. The PC will not boot the System Restore CD's
2. The Original OS install and [HP_RECOVERY] disk sector has been severely damaged by
all of the following:
   A. Massive Virus Infections as shown by Kaspersky Virus Scan and cleaned up.
   B. The user had originally updated the pc to Vista Business Express Upgrade
       (Supplied by HP with the original purchase and warranty).
        (Prior to the upgrade, Media Center was working correctly.)
   C. The original OS product key(XP Media Center Ed. 2005) has been changed by the Vista Business Express upgrade.
   D. The destructve recovery done by PC-Doctor has done user file damage(s).
   E. All software, and possibly hardware could be corrupted & damaged by viruses,
   incomplete recovery, and the unknown failures and conditions.
To sum up, the system is locked in an unknown state, waiting for expert help.
(I can allow and manage to let someone diagnose, repair remotely using another OS i.e.Linux Opensuse 12.1, or XP Home ed if needed.)
SO IF YOU THINK YOU ARE UP TO THIS CHALLANGE, SEND MESSAGES TO DAVHPForum anytime. Thanks in advance!

PowerPC G5 will not boot (from CD, single-user, verbose...) - is it dead?

I had posted this in the OSX forum but had a suggestion to post here as well - any suggestions would be greatly appreciated!
My PowerPC G5 (10.4.11) will not boot. It gets to the grey Apple screen, and then freezes there, no progress dial, and the fan starts racing after a couple of minutes sitting there. Here is what I have tried so far and the results:
-Will not boot normally - freezes at grey screen
-Will not boot from CD (DiskWarrior, 10.4 Install disc OR 10.3 Install disc - which came with the G5, each time it freezes at grey screen
-Will not boot in safe mode - freezes at grey screen
-Will not get into single-user mode, freezes at "DART-enabled"
-Will not get into verbose mode, freezes at "DART-enabled"
-Holding option when starting up allows me to select a drive (hard drive or CD), but then freezes at grey screen when attempting to boot from either drive
-Option-Command-Shift-Delete does nothing when starting up, again freezes at grey screen
-Option-Command-P-R does not work - well, maybe it deletes PRAM, but it never even gets to the grey screen, freezes with a blank (black) screen, so that can't be right
-I CAN get into open firmware & eject cd, cannot boot up from there - it freezes at the grey screen with a circle w/a line through it
-Attempted to reset NVRAM from Open Firmware, "reset-nvram" and "set-defaults" both were ok, then it froze after "reset-all"
I have tried everything I could think of and everything I can find - Does anyone have any possible suggestions or ideas for what I can do?
I had a couple suggestions that it could be RAM, so I'm going to try to run Apple Hardware Test, though if I can't boot from a CD, that will make that very difficult. Any thoughts?

Hi svman8-
Did you also reset the SMU?
One thing known to cure various ills is to replace the battery.
This may be a helpful link:

BIOS update, then will not boot from any drive

This old laptop, 3000 C200 8922 was acting very clunky when on wireless.
Downloaded Bios Version 63ET62WW and flashed it into the bios.
Now, even though I can get to the bios screen, and it shows the hard drive, DVD/CD drive, it will NOT boot from either.
It will also "see" a usb installed, but will not boot from it.
I have removed all power and cleared the CMOS several times and I still have nothing. Tried two different hdd's which have been in the machine and same results.
HELP!! I should have never messed with it......

hi k4pew,
One rule after a BIOS update is to Load optimize deafults after updating.
Try that go inside BIOS Hit F9 to load defaults then F10 to Save and Exit.
If not
Try turning on the computer and start hitting F1 to load the Recovery Menu and see if that will push then Try Reseting the PC.
If still the same Im afraid that the BIOS needs to be reflashed.
Im not aware of any flash tool or a your Previous BIOS Version Firmware available for download.
You can try calling Lenovo Technical Support for any options available for repair.
Im sorry to hear what happened

Wiped macbook pro will not boot from install DVD

I recently purchased an older MacBook Pro that came with the OS system wiped but it did have the original Install DVDs. The computer will not boot from the DVD. I have booted holding down the C key and nothing happens. I have booted holding down the Option key and it shows the Install DVD and I select this and nothing happens.
How do I get it to open up the Utilities from the DVD to install the operating system?

It could be a problem with the optical drive, but also may be due to the DVD's being for a different model.
Exactly which MBP do you have, and what serial numbers are on the discs ?.

Optical drive trashed and MB Pro will not boot from USB image

Hello,
New here but I have searched and tried all I know to get this MBP working right again. My disk drive is trashed and has been for some time now, this is why I have a bootable version of Snow Leopard on an 8G flash drive. When my MBP began acting funny recently and I went to disk utility to verify permissions and the disk. Both failed = must boot from disk to repair, thus my issue. For some reason by MBP will not boot from the usb image I have used previously??? Pressing C or Option during startup does not work. If I press Option, I only get the harddrive option, C yields nothing and the computer boots normally.
Please!! let me know how / what you would do to resolve this. I don't understand why I have previously been able to boot from this same file on the same drive previously to repair my disk / permissions but cannot do so now. FWIW, I tried placing the file (OSX) on my external HDD to boot from, this did not work either (USB HDD).
Thank you in advance for your input!!

It isn't clear what you mean about your HD being trashed or which disk (HD or USB drive) you are trying to repair, but either way you need to start up from your Snow Leopard installer DVD & instead of installing anything go to the Utilities menu & run Disk Utility from there to repair either or both of the disks.
