Boot from disc problem

trying to boot from start up disc - hold down the 'c' key on restart with disc installed and it just sticks in a loop of restarting, never coming up to a screen to work from

start your computer normally and see if the disk will mount while your in osx? you can always reinstall from there if thats what your trying to do.... then hit restart while holding down the C key until you get to the apple symbol then release the C key.

After OS Upgrade, Computer will No Longer Boot from Disc, Enter T-Disc Mode

I purchased the Leopard update about a week ago and proceeded to install it (upgrade option) on my MacBook Pro previously running Tiger. After this update, I no longer seem to be able to boot from a disc(c on startup), enter target disc mode(t on startup), enter single user mode(command s on startup), basically anything that requires hitting a key on boot. In short, the operating system seems to override any of those commands and just loads regardless of what I press.
How can I fix this?? I fear that if my mac suddenly dies, I won't be able to fix it with archive and install via the CD, since I can't boot from it. I also won't be able to recover my files with target disc mode or anything.
For more in-depth details:
-My hard drive does have an open firmware password- it was recommended as part of the undercover anti-theft program that I use. Although I can tell putting the password on was a mistake, since I've read that single user mode is no longer accessible with this password active. I don't think this is affecting my inability to boot from disc or target disc mode though, as I was always able to do this with Tiger, even with the firmware password active.
-I have tried booting from other discs, like my old tiger OS disc that came with the laptop- that fails too.
-My Leopard installation was not clean. Like many others, I used the upgrade option and it appeared to work ok- until restart, where I was faced with the blue screen. Since I was unable to boot to single user mode and try removing potential APE files, I let the computer sit for an hour on the blue screen until it finally loaded. Upon getting in, I found that I did not even have APE's installed. I proceeded to reinstall the operating system via an Archive & Install. Upon boot after this reinstall, I still received a blue screen that lasted a long time, and the OS loaded very slow. It did this for a few additional boots afterwards, and has appeared to smooth itself out now, a week later. The OS now loads fine and works alright (from what I can see), but I still can not boot from disc or anything else.
If anyone at all knows a solution for this, it would be much appreciated. I wanted to suspect something like the disc drive going bad, but being that things like the target-disc mode aren't working either- I'm hesitant to believe its just the disc drive. Being that it also happened just as I upgraded to Leopard and faced issues, I have more of a hunch that its something to do with Leopard.
I apologize if this has been answered before, but I've looked all over the site, google, everywhere I could think of and came up with no answer.
Thanks ~Brian

Hi, I have been having the exact same problem with a late 2011 MBP 15 inch. I replaced the hard drive with a samsung SSD 1.5 years ago, along with a samsung SSD in the optical drive. It worked great until the Yosemite upgrade. The MBP seemed to work reasonably well for a few days after the upgrade, but then it started stalling on various programs (spinning beach ball on Mail, Safari, etc). Start-ups were also longer and had a loading bar each time, which was new since the upgrade. I left the MBP to sleep last night and when opening it, it crashed and tried to restart. On restart it loads to the login screen, then after I enter the password it partially loads (based on the loading bar), then shuts off. I removed the SSD and plugged it in with a USG, but that didn't change anything. Here is a picture after using CMD-V before it shuts off.

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.

MSI NF980-G65 freezes when trying to boot from disc

I just recently purchased and received an MSI NF980-G65 motherboard to work with my AMD Phenom II x6 1055T, but sadly I have had nothing but trouble.
So far the motherboard posts its bios and has the ability to detect any (and all) of my hard drives when I have them plugged in. The hard drive that has Windows installed on it currently informs me that I need to put in my Windows disc and run the repair utility, which makes sense since I was using a completely different motherboard and CPU before.
It is when I try to press any key to boot from disc that the problem arises. When I press a key on my keyboard while that prompt is on screen, the cursor jumps as if I had hit the tab key and does nothing further.
I have a total of three copies of Windows 7 at my disposal to use, two are DVDs I had burned from using my student discount to get them, and one set (32-bit and 64-bit) were in a retail copy of home premium, all of the discs performed the same action. I had tried using different SATA cables, different power adapters, and even different DVD players to try and remedy the situation.
The hard drive with windows is an IDE hard drive, but I have tried my other SATA hard drives just to be sure, none of which fixed the problem.
I have heard briefly about m-flash, but as far as I can tell, it would appear this new motherboard did come with the latest bios version (1.4).

For the boot, I have tried both setting up the DVD player as the initial boot, and I have tried just selecting it in the boot menu.
As per the posting guide, here are more specific information:
Processor: AMD Phenom II X6 2.8 GHz, 9.0 MB Total Cache, AM3 Socket
Motherboard: MSI NF980-G65 v. 1.2 bios (I'm going to try and flash this to a later now, I didn't know where to look for it before) , 601-7612-010B1004183389
RAM: G. Skill Ripjaw DDR3-1600 PC3-12800 2gb x 1 until I get this working, then it will be x4
Power Supply: Tagan BZ Series 700W
DVD: Samsung SH-S223 DVD burner with Lightscribe
HDD: Western Digital 250GB IDE drive

Cannot boot from disc

Holding down "C" does not boot from disc. Computer does boot normally. After entering password -- which is accepted -- there is no dock or access to apps.
Reset PRAM does not work.

I just found another possibility:
So you cannot get to single user mode... can you get to open firmware, and reset the non-volatile RAM?
Cmd-Opt-O-F at boot
reset-nvram
set-defaults
reset-all
(each line exactly as shown, followed by <return>)
I'm now able to repair the volumes. Waiting for it to finish and reboot.

Intel iMac won't boot from disc or in safe mode - cannot repair disk

I have an early Intel iMac 20" (2GHz core duo) that generally works fine. I recently ran Onyx and it reported a startup disk error, suggesting I insert the install disk, hold 'c', and use disk utility to repair the disk.
NOTE: I have performed this operation successfully in the past and know how to do it.
On this occasion, the iMac simply booted up to the normal desktop each time after multiple attempts at booting from both the original OSX 10.4.4 install disc and the OSX 10.5.1 install disc (current os is 10.5.8).
I then attempted to start holding 'shift' to start in safe mode but again, repeated attempts all landed me on my normal desktop.
I then attempted to hold 'option' to be given the choice of startup disc but again was ignored and went straight to my normal desktop after multiple attempts.
Note that my iMac appears to be running fine otherwise. I was just trying to perform some routine maintenance and have run across this problem.
Any ideas? This mac will be 5 years old soon and I would like to keep it running for a while longer.

Hello Devoidarex
You'll want to use the Leopard Install DVD to Repair your Startup Volume and may want to try a USB keyboard if your using a wireless.
Another option is to insert the DVD and go to: System Preferences > Startup Disk > select the Install DVD > then Restart.

MacBook won't boot from disc

On Sunday my ten-month-old MacBook froze up and made some nasty clicking noises. I forced a restart, but now it just boots to a white screen and, after a good five minutes or more, eventually displays the blinking, question-mark folder.
I'm quite certain the drive is toast, but what I find more interesting (and in some ways more irritating) is that I can't for the life of me get it to boot from a DVD. I've tried my Leopard disc and the install disc that came with my computer. I hold C while booting, the drive spins for a bit, and eventually it just spits the disc back out. I've also tried holding D with the original install disc to boot the Apple Hardware Test and get the same result. I've tried holding Option to get a list of boot volumes and just get a white screen with a mouse cursor. I've tried resetting the power management unit and zapping the PRAM, as suggested in the "What to do if your Mac won't boot" list, and have noticed no change.
Thoughts? There must be something else I can do.

You may have a bigger problem than just the Hard Drive. Call Apple support or go by an Apple store if your near one and talk to them. You've done everything you can do. It will be up to them now. Be thankful it's still under warranty.

Adobe on Leopard, refuses to boot from disc, disaster?

After buying Adobe CS3 Web Premium, I found out I couldn't install it because my drive was formatted as case-sensitive. So, I was forced to backup all my important data and re-initialize. I zeroed the drive, but told it to skip zeroing just before it was done with the last little sliver in the progress bar.
So, I get all the whole system updated. Install Aperture, Thunderbird, Firefox... everything is going great. Then get the updates for Aperture, everything works flawlessly. I had never seen it run so well. Then I finally install CS3 and the install process seems to go without a hitch.
So, I've got CS3 on there, but I want to do some stuff with Aperture before I get into it. I'm working with Aperture and everything is going great. Good performance, really speedy. Then, I decide to open Illustrator CS3. To my horror, Aperture starts to go completely wrong. It gets to the point where I can't use it for longer than 30 seconds without having it crash. So, I quit Illustrator and the problem persists. Finally, I decide to restart the machine, Aperture seems to have fixed itself with restart, everything seems to be alright, for now.
Hmm, I think, maybe the CS3 needs to be updated. Yes, it did, 524 MB of updates. The installer downloads it all, starts the updating process and hangs silently (liquid in the progress bar still flowing). I get no notification except in Activity Monitor, where launchd and another process (I forget which) are going crazy with the CPU. I force-quit the updater from Activity Monitor, reopen it, press the install button again. It doesn't do anything, so I found out I actually have to say "Delete All" as in, delete all the downloaded updates. Then the updater quits itself and I have to reopen it and redownload and install whatever the installer thinks didn't get updated. I had to force quit, delete all, redownload, and install about 5 times before it said it was through.
Oh man, that was bad. Now the whole machine is pretty much a sluggish mess. Naturally, I thought, "I'll run Disk Warrior." I had run it with an earlier version of Leopard before, so I expected it to work. Insert Disk Warrior, Restart, hold C key, disc spins for a second and ejects itself. System ignores my command and boots from hard drive.
But everything loads and things seem alright, so I think, "oh well, I guess everything is alright." I do some work in Illustrator, everything seems good. Listening to music, but not working in Aperture. The machine works great for about 2 days. Then, I decided I want to install Final Cut - I put in the Install DVD, it spins for a second and spins back down, nothing happens. No desktop icon, no optical drive showing up in Disk Utility, Eject button on keyboard doesn't work, iTunes - control > Eject Disc, now my iTunes is hung. I try to force quit, nothing happens. Force quit dialog, iTunes is listed as if it hasn't crashed, click force quit, it remains in the list. iTunes icon remains in the dock, arrow still below, but does nothing when I click it and won't poof. iTunes doesn't show up in Activity Monitor.
Okay, "definitely gonna try Disk Warrior again," I think to myself. Restart, reset PRAM twice, hold option to boot select screen, press eject to remove FCE disc, insert Disk Warrior, Disk Warrior icon shows up on screen, click it, click the arrow to boot to it. Wait a second - BSOD, no cursor! Disc spins for a while and stops. Press any key, it spins back up again and eventually dies down again, doing nothing. Forced shutdown holding power button, press power again, hold the C key to boot to disc. Disk Warrior spins up again and spits itself out, just as before. System boots to hard drive instead.
What am I doing wrong? The Mac Pros at school run Leopard and CS3 and they seem to be flawless. Am I the only one having these problems? I can't figure out if this is hardware or software. I'm currently creating an image of the Disk Warrior disc. I plan to restore it to my hard drive's second partition and see what happens. I'll let you know what happens. Until then, can anybody give me any hints on what might be wrong with my system or at least give me some sympathy? LOL. This is beyond frustrating.
I'd had my system ignore what seemed like successful insertion of optical discs and refuse to eject them before the fresh install, but I've never had it refuse to boot from a bootable disc like this. Any ideas?

MacBook Pro will not reboot after Security update or boot from disc

I recently downloaded the latest security update and instead of immediately restarting I chose to shut down the system. The next day I booted up and ran into a problem with the start up stalling on the gray screen with the Apple logo and the spinning gears.
After searching through many topics on this issues I have determined that I can likely repair permissions to resolve this issue or try a number of other options. However I can not seem to boot up from the Install disc or in Safe Mode. Booting up holding down the Option key doesn't give me any other option than the hard drive.
Does anyone else have any ideas on how I can get past this increasingly annoying spinning gear mode so that I can try to repair the damage?

This is what worked for me:
Situation: After installing OS X 10.5.6, my mid 2007 MBP began to freeze, and eventually wouldn't reboot normally, nor in safe-mode or from a disk. Also tried resetting SMC and PRAM, still would boot from disk.
Tried fysk, which worked for a while, but eventually the computer wouldn't reboot again.
Connected it to another mac via firewire in target mode and erased all the data (yes I had a time machine back-up), but still wouldn't reboot from disk.
Solution: A friend of mine tried resetting the PRAM again (command, Option P,R) but this time, he continued pressing the start button until the third chime (rather than the second as per apple instruction).
All of a sudden we were able to reboot from disk, reintall the OS X 10.4.9 and then do a regular update to 10.5.6. My MBP has been working fine ever since.
Hope this helps someone.

IMac G5 hangs on startup, won't boot from disc

Hello,
My brother's computer has been acting up and I've been unable to fix it for him...so I was hoping I might be able to get some advice here.
Problem: hangs on startup. It goes to the gray screen with the Apple logo and the spinning progress wheel like it normally would, but never gets past that. You can hear the hard drive working and eventually the fan comes on.
What I've done:
1) attempted to boot from OSX disc, same result
2) attempted to boot from Apple hardware test disc. this brings up an open firmware terminal style prompt but does not boot from the disc. using the prompts i reset pram and did the "reset all" command which restarted the computer but it continued to hang
3) opened it up and pulled the only ram chip out and put it in the other slot. Unfortunately we don't have another chip to test out, but if you guys think it is a likely culprit I'll go buy him one to see if that fixes it.
Any advice will be appreciated. Thanks!
-Alan

Do you hear the drive spinning up? Have you tried a safe bootAfter the startup tone, hold down the <shift> key until you (hopefully) reach the desktop, it will be longer than normal, because Disk Utility's "repair" is invisibly run; it also will bypass any login items. If the system gets to the desktop OK this time but stalls when the shift key is NOT held down, the problem may be some login item that will need to be removed, using the Accounts panel of System Preferences and its Login Items section.
You could try to repair the machine using Target Disk Mode to access it.

Windows won't boot - can't boot from disc either

Trying to help a friends HP Touchsmart desktop unit. It will not boot. It sits at the Windows screen and does not move beyond it. Getting the computer to boot into safe mode provides the same results. it cannot get beyond the boot screen from Windows.
So I am now attempting to do a system recovery. The problem is, I cannot get the computer to boot from the disc. I was successful once, did a recovery, but then got the BSOD. Now I am just trying to get this thing to boot from the cd again, and it will not respond. In the BIOS, i have set the Disc to be the first device, but to not avail.
Any help would be appreciated - Frustration is growing! Thanks!

Hi,
a few questions'
1. to which sure- which Operating Sysytem is trying to boot ?
2.Prior to this failure has any new program,software, hardware - or any kind of new peripheral been installed (including USB operated hardware) ?

Macbook Pro hangs when trying to boot from disc

I'm attempting to reinstall OS 10.6, and normally it works just fine. However, I got this computer, it reads the Leopard disc just fine, I restart, hold down C and it just hangs out on the apple logo for hours on end and won't boot to disc.
Any ideas?

Spinning gear? Never in my mac years have I seen a spinning gear when booting from the disc.
You should see what is variously described as a spinner, a spinning gear, or spinning clock appear below the Apple logo during startup any time you start up your Mac, whether from a DVD or HD. The spinner looks like a radial set of lines rotating in a clockwise direction, & indicates the kernel is loading, as described in Intel-based Mac: Startup sequence and error codes, symbols.
Booting from the original snow leopard cd; I don't believe I possess the original restore disc anymore.
In your first post & in your current profile info you indicate this is an MacBook Pro 17" Core i7 model; in your second post here the "Core i7" part is missing. This makes it hard to guess which 17" MBP model you are talking about. Note that each model has a minimum OS build version requirement & cannot start up from a lower version than that. Use the chart in Mac OS X versions (builds) included with Intel-based Macs to identify which version this is for your MBP & make sure your Snow Leopard DVD runs that version or later.
For instance, if this is a Core i7 MBP, it must be a Mid 2010 model & requires at least version 10.6.3, build 10D2063a, 10D2094, or 10D2101a. An original Snow Leopard DVD has version 10.6 & will not work with it.

Boots from disc, but doesn't recognize hard drive

I've got an 800mhz G4 iMac and it won't start up. It boots really slowly into the blue screen and then never passes that point. It's just a blue screen. I can move the mouse around, but nothing else happens and there's nothing for the mouse to manipulate.
It will boot from the optical drive and I'm trying to reinstall Panther (can't find Tiger upgrade discs...blast). But when it gets to the point in the installation where it asks which drive to install on, it gives me no options.
Is the HD dead? Anything I can do? Thanks for all your help in advance.

Try things in Apple doc.#106464 for your startup issue.
Also, try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption. Smokes link will help walk you thru it. You will need the Tiger disk to do this if you have Tiger installed. If your Panther disk is a 10.3.9 version, it will repair a Tiger installation. 10.3.9 only though.
Let us know what errors DU reports and if it was able to repair them.
Try these things before a re-install. You can try things in Apple doc.#106214; run fsck-you can run a repair with out the disk this way.
Cheers!

Won't boot from disc...

I'm running a less than a year old iMac with 10.5.8 currently installed.
I've been trying multiple times to install SL but the disc will just not stay in the drive to be booted from.
I've tried entering the commands to force the computer to boot to the disc on restart and I've also tried installing from the disc while being booted up.
It is almost as if the computer doesn't think its an install disc when it restarts, am I approaching something wrong here?
Thanks.

That will be a puzzle. It could mean that the disk is not working perfectly and that error correction routines don't work as well in the installer as they do with a working OS.
On the other hand, being able to restore the DVD to a drive from a working OS may also be possible with a less than perfect optical drive due to the OS re-reading data with error checking until it get's the data right.
I've gotten some optical drives to work pretty well by just using a 'cleaning disk' that you can buy from a electronics store for about $10.
It seems like drives on which I've had to use a cleaning disk do work for a few months, but then fade away and eventually need to be replaced anyway.
So, you can't go wrong with trying to get a replacement disk, and keep one eye on the optical drive itself.
Meanwhile, for me, I keep many installer disks as bootable partitions on a 250GB external FW/USB drive that has quite a few partitions on it. Hard drives are much faster for installing an OS or running a boot diagnostics or repair disk, and I never scratch my disks.

Booting from disc vs erase and install from disc

I need to erase and install.
I need the cleanest installation. I was thing about "erase and install" from the disc.
I know some people like to boot from the disc.
What is best?
Thanks.

To do an erase & install, you'll have to boot from the disc.
 Cheers, Tom
