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."

It might mean overheating or worse things too.

Will Not Boot From Install Disc

Upon a Verify Disk check I received a "Volume Header needs minor repair" notice.
Because it is necessary to boot from another disc to repair the header, I attempted to boot from the install disc. I tried restarts holding down the "C" or by selecting the start up disc in System Preferences/Startup Disk. I've tried each of the these several times to no avail. The machine will not start from the install disc. It keeps starting from the machine hard drive.
Are there any other suggestions how to force it to start from a startup disk?

The installer disc problem is still a concern but in the meantime you can try booting to Safe Mode. Run Disk Utility again from Safe Mode and see if it still reports problems. Boot normally afterward.
[Mac OS X: Starting up in Safe Mode|http://docs.info.apple.com/article.html?artnum=107393]
[What is Safe Boot, Safe Mode? (Mac OS X)|http://docs.info.apple.com/article.html?artnum=107392]
[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
[Mac OS X 10.4, 10.5- Computer shuts down during Safe Boot|http://support.apple.com/kb/TA24054]
Safe boot mode runs a directory check command similar to that used by Disk Utility's repair. In Tiger it ignores some stored information (cache) that is normally read that speeds up the boot process, and it moves some other caches to the trash. It also uses only System fonts and disables all Startup Items, third party items, and any Login Items.

My Mac Mini Will Not Boot From Install Disc For Re-Installation

I've tried all (at least the ones I've found) workarounds to get my Snow Leopard Install Disc to boot, but it will not. When the computer boots normally (without the DVD), I can insert the DVD and access it from there. However, when I try to use the utilities on the disc, it requires a reboot that ends up telling me to turn off my computer. I have a Late 2010 Mac Mini and I have yet to try booting from a disc, so I don't know if this is a new problem or an old one. Any help would be greatly appreciated.

Unplug everything from your computer except a wired keyboard/mouse and the monitor. If your Mini still won't boot from the install DVD try resetting the PRAM and SMC.
Intel-based Macs: Resetting the System Management Controller (SMC)
Resetting your Mac's PRAM and NVRAM
If that doesn't fix the problem remove any RAM (if you upgraded) and replace with the Mini's original RAM. There is also this document you might want to read, Mac OS X: Gray screen appears during startup.
If that all fails I would take the Mini to the Apple store. It should still be under warranty if you bought it late last year.

Holding c while resarting but will not boot from install disc

hello,
I have a G4 Titanium Powerbook currently running os 10.3.9.
I have been having troubles ever since upgrading to Quicktime a while back such as Quicktime not playing files, missing codecs, Pro-Tools and other software crashes, Itunes will not open with M-Box connected, etc.
I have tried to repair permissions with the disk utility and still same issues.
I have backed up all important files and would like to just reinstall the os 10.1 using the disc I got with the powerbook hoping to be able to upgrade back to 10.3.9.
I have tried to shutdown with the disk in and turn on with the c button pressed and it still boots up as usual.
I have also tried to restart holding c and still boots up as usual. I just cannot seem to get the powerbook to boot from the install disc.
The disc is the powerbook g4 mac osx 10.1 install disc.
What am I doing wrong?

i have the following discs.
mac osx install - which is 10.1
mac os9 install
software restore 1
software restore 2
mac osx developer tools
I have tried to boot by holding c with the mac osx install and the software restore 1 discs to no avail

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:

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 ?.

Macbook Pro will not load OS and will not boot from Install Disk

When I try to turn on my macbook pro it goes to the gray logo screen with the spinning gear however it does not progress from there and then after several minutes it proceeds to restart itself and the same process repeats itself. I have tried to boot into single user mode with success and have run /sbin/fsck -fy and that has returned that the volume appears to be ok. However, when I hit reboot it returns to the same process of the gray screen and spinning gear to black screen which repeats. When I boot into verbose mode it progresses to AppleYukon2: RxRingSize <= 1024, TxRingSize 256, RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328 then it stalls for several minutes and then it shows continuing
synchronizing disks... Killing processes
then it says some other stuff to fast to read.
When I try to boot from the install disk it will not boot from holding the c key it goes through the same aforementioned cycle. When using option to boot I can see the Disk then when I select it the cycle happens again.
Also I have XP installed and I am able to boot into that successfully. Any help would be greatly appreciated.
Not sure if I left anything out

Welcome to Apple Discussions.
Do you have multiple Accounts defined on that system? The last time you successfully were running, did you run from the Account with Administrator privileges?
Do you have another computer from which you could boot and connect the Macbook Pro in Target Disk Mode to take a look at the drive from your working machine? Perhaps you can run Disk Utility from the working machine and point to the hard disk on the failing Macbook Pro.

New hard drive. Will not boot from install dvd.

Earlier this week, I dropped my computer.
It was probably a 3 foot fall.
Computer froze, so I restarted and got the flashing folder with question mark.
Started in internet recovery, and disk utility confirmed that I had killed my hard drive.
Got a new hard drive and installed. Started in internet recovery, formatted hard drive. Disk utility says it's good to go.
Was given the option to install Mavericks, but keep getting an error message.
Attempted to restart from install dvd that came with the MBP. Tried every startup shortcut there is.
Optical drive recognizes the disk, but I always get stuck on the gray screen with the wheel.
Reset PRAM. Reset SMC. Same problems. I do not have access to another mac or a PC with admin rights.
I'd rather not brave the Apple Store this weekend in the snow in a town that never gets snow (people drive poorly on a good day!).
Any tips?
Got the MBP in 2010, new. Was running mountain lion when I dropped it.
Thanks!

Yiou can't use Internet recovery on a 2010 Mac notebook to install any version of OS X on it. That is why you are getting that error. You have to use the original System reinstall discs that came with it to install OS X on a new drive or use the OS X reinstall disk to restore from a time machine backup.
Since your system doesn't seem to want to completely boot from that disc you should try an external DVD drive that connects by USB port as the built in superdrives are known to fail or partially fail at any time. Don't buy an Apple external Superdrive as they only work on Mac computer that did not originally come with a built in DVD drive. Any Brand external DVD drive will work on your Mac except Apples own external DVD drive.

Satellite P300-1A8 will not boot from disc drive

Hi,
I had a little play with start up programs, partitioning the hard drive and marking as active and deleting programs i thought i did not need.
I obviously had no idea what i was doing!
Laptop will go to toshiba screen then goes blank, i can not boot from the disc drive.
I put the hard drive into another laptop and it works fine.
I put the hard drive of that laptop in the buggered one and that works fine.
How the hell do i put the original one back with it working??
Really really stuck with this!!!!!
Any help would be appreciated.
Only thing i havent tried is the recovery disc but im not paying for one if it wont boot as itl be a waste of money.
Seems like its a compatability problem with cpu and hard drive as they dont want to be friends anymore!!
Thank you in advance

Hi!
Can you boot in the safe mode?
If you dont have a recovery disk, use the Microsoft installation disk and try to boot from it.
And you said that you cant boot from disc drive, did you tried different disks?
Maybe some are not readable or not bootable.
The best way would be a recovery disk. The installation takes a few minutes and you have a clean installation with all drivers and tools from Toshiba.
Bye

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!

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:

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!
Jesse

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.

Power Mac G4 400 MHz (AGP graphics) will not boot from hard drive

I have a Mac G4 400 MHz (AGP graphics) Machine Model: PowerMac 3.1 CPU Type:PowerPC G4 (2.8)
When I try to boot from the hard drive I get the folder with the flashing question Mark. The Machine will start up from the OSX 10.4 installer disk.
The system was running OSX 10.4.9 fine. I began to have problems with the hard drive, so I replaced it with an old Maxtor 5T040H4 40Gig Apple branded drive that I had sitting around.
The drive is jumpered (r50) for Master/Single.
I erased the drive in the old G4 using disk utility and wrote all zeros. I then used my store bought Tiger 10.4 install disk to install 10.4 on the drive.
After restarting I still get the flashing question mark. If I leave the Install disk in the DVD drive the system will attempt to install again.
I have zapped the PRAM, pressed the CUDA button, removed the battery and let the system sit unplugged for over and hour and it still will not boot from the hard drive.
To test the drive I removed it and put it in a Granite Digital firewire enclosure and connected it to another mac. The drive shows up and the system appears to be installed correctly.
What am I forgetting to do? Does anyone have any suggestions.
Thanks in advance.

Hi! If Tom's solution doesn't work I would reboot from the install disc and then partition the drive as 1 partition instead of erasing it. Sounds like the driver on the disk is too old and installing a new partition map should write a new driver to the drive that is compatible with Tiger. Other than that it is possible that the drive has a spin delay jumper enabled and the drive isn't spinning up fast enough and the computer isn't looking long enough for the drive. Tom

T500 will not boot from bootable CDs/DVDs, but will read and open files on them

System: 2 T500s, both manufactured early April 2009, win XP, ATI Radeon 3650 graphics,4GB RAM, latest Lenovo drivers installed..
Problem:- Our 2 T500s cannot boot from any windows coded recovery CD -except Lenovo's rescue/recovery discs. Some -but not all- Linux code recovery CDs do boot the T500. Every other kind of CD and DVD such as audio and video works fine in windows XP.
Here an example of our 2 T500s' failure to recognise bootable CD/DVD discs. All the files and folders on a Paragon Partition Mgr v8.5 Recovery CD can be viewed in windows explorer and files such as jpg, txt and zip can be opened. This CD will not boot the T500, however, it will boot our other -non-Lenovo- computers. The same applies when the media are DVDs with identical content.
We have tried several different kinds of CD and DVD media to no avail. Burning the media on other computers and using several kinds of burning software does not help, ourT500s refuse to boot from them too.
The problem seems clear enough, on starup our T500s fail to distinguish between windows coded bootable and ordinary CDs/DVDs -unless they are Lenovo recovery/restore discs.
A solution would be gratefully received.

Thank you for your very kind assistance,
Q: "1. Did you apply the DVD firmware fix here?"
A. It was` already installed on our 2 T500s. We have also applied just about every driver update from Lenovo.
Q: "2. Did you try booting from a USB optical drive that you first attached to another system where you could verify that booting from it was possible?"
A. Yes, many times from a USB CD/DVD drive, it failed too. We burned on that drive too, but the T500s will not boot from those CDs either.
Q: "3. In this thread the solution was to use another burning program than Roxio..".
A. We have used the Paragon internal ISO creator/burner, the Roxio burner that was preinstalled wth the T500, BartPE internal ISO/burner ,InfraRecorder and others too. Made ISOs and burned from them, burned CDs directly on the fly etc, all to no avail..
For some reason, our two T500s' CD/DVD drive controllers or some intermediate software act as if the CD's boot sector is not present. Clearly, something (BIOS, software, unstable hardware, or ? ) is blocking the read or write of the data necessary to boot these CDs. Whatever that 'something' is, it has no effect on burning and booting Lenovo recovery CDs.
The bizarre part of all this is that a`Lenovo recovery CD burned on the T500 drive WILL BOOT the T500. A Paragon v8.5 recovery CD or BartPE CD burned in one of our non-Lenovo computers will boot ithat and every other computer we have except our T500s.
PS Thank you for the link to the new version of Roxio, will download and install it.
