Macbook pro 17 inch early 2008 will not boot from disk

My macbook pro will not boot from from disk. I am running 10.6.8. Tried loading the disk that came with system holding down the C and you can here the drive working. It came back and said to restart computer by holding down the power button and poering it back up. Tried that and nothing. The software I tried to load is 10.5.4 Also tried loading os x snow leopard 10.6. Same thing happens.

Have you reset the SMC? If not, try that.

Installed Yosemite update on MacBook Pro retina late 2013 will not boot flashing folder with ?

I just Installed Yosemite update on MacBook Pro retina late 2013 will not boot flashing folder with ?

dunno, Lynn--maybe Etrecheck. trying running disk utility to verify the status of your hard drive. That may give you a basic idea. Perhaps tech tool pro. As for it running hot, I can't say for sure. try shutting it down and using a vacuum clearner +crevice tool around the back of it. It's been my experience that hard drives usually fail without a lot of warning, luckily you have a backup. Afterwards you can say "Yup, that went bad". I've done a little research and found out that your MacBook Pro doesn't come with a conventional hard drive as such, but an SSD (solid state device) . It's upgradeable (up to 1 TB ) but not cheaply
go here for more info (OWC) :http://eshop.macsales.com. For right now, I'd recommend resetting the SMC/PMU, maybe zapping the pram . to do that, reboot, hold down Apple+Option, P+R keys while rebooting. Hold down for 3 chimes, let go and let it boot. as for the SMC thing....
I'm assuming your battery isn't removeable-shut down computer, plug in MagSafe cable . On built in keyboard, on left side, press Shift-Control-Option and power button at the same time. release all the keys and the power button. press power button again to turn on computer
that is all

My MacBook Pro 13'' Early 2011 is not booting.

Hello,
I have a Macbook Pro 13'' Early 2011. Last week I tried to replace the thermal paste on the processor and on the graphics chip. I followed a video tutorial and an iFixit tutorial step by step during the entire process. Once I was finished I decided to turn on my Macbook and give it a spin. Unfortunately it didn't work, although I haven't touched or damaged anything on the logic board, as far as I'm concerned.
The scenario goes as follows:
I press the start button..
The fan spins once, the hard drive reads for a second and the sleep button flashes for a moment. I am not hearing any chime, neither does my screen go on.
The Macbook Pro turns off again automatically.
I am going to open it once more before it give it to the authorized Apple service. Do you have any idea where the issue might come from?
Thanks for your replies!

If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the startup drive, or some other hardware component, is failing. Back up all data immediately, then make a "Genius" appointment at an Apple Store to have the machine tested.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

Mac Pro Early 2008 will not boot off Win7 Install DVD

Hello,
I am hoping someone out there will have encountered something similar and have some suggestions or ideas, because at this point I can't think of anything else to try.
I have a 2.8 Ghz 8-core Mac Pro (Early 2008) with an Nvidia 8800GT Graphics card. I am running OS 10.6.2, fully patched and updated.
I am attempting to install Windows 7 Ultimate via Boot Camp, and am encountering a rather odd problem.
Once I have launched Boot Camp Assistant it allows me to partition the drive and does so correctly, but when it attempts to reboot off the Windows 7 installation DVD, I encounter a blank grey-white screen similar to that which you normally get on startup but without the Apple logo. This continues for some time (it seems to vary), and then the screen goes dark and the monitor says it is receiving no signal. The fans on the Mac Pro go for a while, then it goes to sleep. I've tried leaving it for a couple hours, no dice.
I've tried both the 32-bit and 64-bit Windows install disks. I had the release candidate for Windows 7 installed previously, and it worked perfectly. I have since tried that same install DVD that I used to install the release candidate, and it encounters the exact same issue. Booting up off the Snow Leopard Install DVD works fine.
I tried doing a clean install of Snow Leopard on a spare drive, booting off that, and then starting from square 1 using Boot Camp Assistant to re-partition that same drive. Same problem. No matter what I do or try, my Mac Pro does not want to boot off this install disc. I have yet to try the disc in another machine to see if it works there, and I will as soon as I can, but the fact that the RC disc worked a few months back and now will not seems to rule out the boot discs as defective. I've also tried both my internal optical drives with no change, and no other discs have any issues.
I've already spent an hour and a half talking to Apple Technical Support, and they seemed stumped, so I'm hoping someone will have a notion. If not, I understand and appreciate you taking the time to read this- I have no idea at this point, and I'm generally a pretty knowledgeable user.

Thank you for your reply,
Pull all the drives you have other than the one that you will install Windows 7 to.
I think I will try this next.
Don't put Windows 7 on the same drive as OS X, give it its own.
That was initially what I started out doing.
And you don't even need Boot Camp Assistant.
True, but it's what Apple suggests using.
Might also want to try moving the monitor cable to the other card port.
Hmm, I think I'll try that.
Any other PCI cards or devices attached or installed should also be questioned or disconnected.
I've disconnected everything I could.
Always a good idea to start fresh which I assume you are doing (not trying to upgrade over RC etc).
Yes, the drive was empty to start with.
Honestly it seems like the Mac Pro is generally refusing to boot from any Windows disc. Things I've tried since my initial post:
- Loaded Windows 7 Install disc into my room mate's windows PC... loaded up fine, got to install screen
- Tried his OEM copy of Windows Vista 32-bit, same issue
At this point it seems like maybe some kind of firmware issue or some kind or graphics driver issue, but I'm pretty much grasping at straws at this point. It doesn't seem like it's even getting to the point where hard drives or anything matters.
It does recognize that I have a Windows 7 install disc inserted when I use the boot selector/startup disk chooser.
Thanks for the ideas, I'll try those out and see if any of them help,

MacBook Pro (10.4.5) Will Not Boot.

It is my sister's MBP, but I am the tech savvy brother (says her) and I should be able to fix it. Well, I've tried my trade and failed.
When I started, her MBP would get stuck on the progress indicator (spinning circle) and never move past that.
The first thing I did was Archive and Install, which worked but yielded an incredibly slow system. I told her it was because her HD was too full. We deleted some things and managed to free up 8 GBs of space, but that did not help. I installed some software updates and rebooted the laptop. Unfortunately, it got stuck on the progress indicator again and never moved past it. I was devastated.
I did another archive and install, but was never asked to insert the second install disc. The hard drive is completely full now.
I told her I could format, but she apparently has pictures of her newborn on there that she refuses to let me delete.
So, I brainstormed.
I have a laptop, a PC, and a 8GB flash drive. I put Ubuntu on the flash drive, booted it on the laptop, and connected my laptop to her Mac via Firewire. I could access her HD, but could not get into the photos folder. It said I lacked permissions.
I've tried resetting the NVRAM, repairing disc permissions, repairing disc.
I ran the hardware test and was only presented with an already known fan error. (Her left fan and her battery do not work.)
Her computer now gets passed the progress indicator, goes to a solid blue screen and changes brightness every couple seconds.
I read that I should remove and then reinsert the RAM, but I do not have a screwdriver small enough to open the case.
I was told to connect another MacBook Pro with her Mac to access the files, but I am afraid I will get the same 'permissions error'.
The Apple repair store tried to get my sister to pay a $300 premium for the repairs, saying that the repairs could cost as much as $1,200.
Please ask any questions necessary.
Until 3 days ago I had never touched a Mac.
I have learned a lot in the past couple days, but not enough apparently.
Any help is extremely appreciated.
Also, this might be in the wrong forum. If so, I apologize. Please move it.
- Carson

Unfortunately, I do not have access to another Mac.
I just tried to run that scenario using my Ubuntu flash drive, but there is no way to change permissions.
I would be more interested in getting the MBP to actually work, but I would settle for getting the information of it it.
I have a friend with a Mac, and I will try that solution if nothing else comes up.

Macbook Pro intel core duo, will not boot to anything.

Greetings, I am currently having issues with my MacBook Pro. I get the flashing folder with the ?, but I can't boot to any of the startup utilities. I have tried all that I have read about on other posts, such as, trying to boot with the C key held down (it just gets to the folder ?), booting to disk utility didn't work ( held down keys and it went to the folder ?), I also tried getting to the hardware test, by holding D and having the applications disk in. And still everything I try gets me to the flashing folder ?. Also I do have the CD's that came with the laptop and tried to install from the mas os install CD and still get to the flashing folder ?. The reason it started doing this was because of this...... I had boot camp installed and was running dual boot with windows 7, then I had deleted the mac osx on the drive so I would only be using windows 7. I wanted to reformat the drive after this, but had a hard time finding out a way to actually do this, as the MacBook unlike PC's, doesn't have any BIOS, and at that time didn't know all the key commands to use at startup. So I downloaded a program from the net that can run at windows start and delete the HD before the computer fully boots windows 7. So after I deleted the HD I could not install any program or start any of the mac utilities at startup, and I did the PRAM reset, still everything that I try it gets me to the flashing folder ?, in the end. Could I have deleted all of the startup utilities when I wiped the HD? If so how can I get these back on my MacBook pro if I can't get the MacBook pro to read any files or start up utilities? Any help would be greatly appreciated.

UPDATE: I found a way to download firmware, I thought that it could be the reason I get the flashing folder with ?, because maybe I somehow damaged the firmware on my computer when I did the reformat. Alas I followed the directions to re-install the firmware and still I get to the same flashing folder. I used FirmwareRestorationCD1.4 I think it is the one I needed for my model, MacBook Pro 15" intel core 2 duo, and comes with osx 10.5 leopard I think, the OSX CD is stamped 2008 for 15" MacBook Pro. I can't check the properties of my MacBook because it has no programs on it, but this is what I think it is from memory and deduction. Well now I guess I have to ask the question, is the firmware the programs installed such as disk utility, and recovery mode? I need to read more I guess, and also I thought I needed to take the 1.4 off the end of the FirmwareRestorationCD in order for it to work, but the instructions for making and using the firmware CD is a bit vague. Another factor in this to make things more difficult, is that this computer is my second computer and it's a PC laptop, so I used a program download from the net to write .dmg files to disk, it's called Transmac, could this be another fault in my creation of the CD? I am out of ideas again as to what I need to do to get mac OSX back on my computer, I am still a bit new to the way macs work, so I could definatley use some advice. thanks.

MacBook Pro Turns On, But Will Not Boot

I recently have had trouble with my MacBook Pro (2.4GHZ Duo Core purchased in late '07). Last night before I went to bed I put my computer to sleep after normal usage of my computer. I did not update anything such as firmware or progams in the past few days. I had it connected to a WD external drive and an external monitor as I have for months. When I went to wake up the computer this morning it would nothing appeared on the screen as it normally does. I waited and tried different things, but no luck. After a minute or two, I just turned it off by holding the power button down. After a moment or so, I turned it back on. The cd-rom drive spun up, but the computer did not post (chime), hard drive seemed not to be active, and nothing appeared on either the external display or the internal LCD. I then turned off the computer again. I disconnected everything, removed the battery for a few minutes and then tried to start it again. The same result appeared each time: cd-rom spins up, no hard drive activity, no display.
I tried various things that was suggested in the Apple Support area such as resetting the PRAM & SMC, as well as trying to get it to boot in safe mode and entering the BIOS. Nothing. Before I take it into the Apple store to have it looked at since it is very far away, I was wondering if anyone had any input on what could be wrong and if I am able to fix it myself. Thank you.

It's possible that you have the NVIDIA problem:
http://support.apple.com/kb/TS2377
Not really sure why it won't boot at all. People have reported suddenly getting no video at all, but I think they usually do get the startup chime.
Probably the best bet is to make the trek to the Apple Store, as this sounds very much like a hardware problem. They should be able to test specifically for the NVIDIA problem.
Good luck!

Macbook Pro (Retina Early-2013) will not turn on

I plugged my iPhone into my computer and was going through the process of syncing my music when my MacBook Pro just powers down completely. I've been unable to turn the computer on since then, following the Apple trouble-shooting process.
Interestingly, when I do a SMC reset, the LED color on my MagSafe charger will change to green and then back to orange, leading me to believe that it isn't an issue with either the connection to the power button, or with the logic board itself. In spite of this, no boot-up sounds, no LED lighting up on the Caps Lock button, no nothing.
Has anyone else run into an issue like this before? Were you able to resolve it?

Hello FAHQALL,
The resource below will provide some steps to try if your MacBook Pro won't turn on. Resetting the SMC is one of them. Troubleshooting the MagSafe adapter and installed RAM are also included. There are links in the article for additional support if the computer needs to be physically inspected.

MacBook Pro 15" Late 2008 will not sleep on its own

My MacBook Pro will sleep just fine if I close the lid or select sleep from the Apple menu. It won't, however, ever fall asleep on its own. I've tried resetting the SMC to no avail. Any suggestions as to what I should look for?

Certain settings, e.g. printer sharing, can prevent timed sleep. If it's a brand new Mac and you migrated a fair amount of data from a previous computer, Spotlight may still be indexing. There are other possibilities as well. See this kbase article:

Macbook Pro (2011 Model) suddenly does not boot from SSD in main bay

I have been using Macbook pro 2011 and Samsung SSD (256GB) for about a year.
All of sudden, the computer will not from SSD from the main bay, but it will boot from the optical bay.
I have tried an Intel SSD 120gb which came with the computer, but it does not work either.
However, it will boot from the regualr hard drive from the main bay.
I have read somewhere that it could be due to the hard drive flex cable.
Has anyone experienced a similar problem?

It may very well be a problem with the SATA cable... for some reason (and I don't know why, but...) SSDs seem more prone in 'detecting' a faulty SATA cable than a standard hard drive. Where a hard drive will boot, an SSD will not.
I would advise purchasing a new SATA cable - from ifixit.com or powerbookmedic.com - and replacing the cable. That (normally) clears up the problem.

G5 will not boot from disk

I cant get my G5 to boot from a dvd....
It will boot off of my hardware diag dvd ,but not off of any 3 of my install disk
Any ideas?
I tried a few commands in Open Fimware prompt :
reset-nvram press Return on keyboard
set-defaults press Return
reset-all press Return
and when i tried the commands the first time, my computer restarted and was able to boot from the os dvd...( after i got it working, i turned it off and tried again, just to see if i fixed it)( i didnt fix it).but now when i type the commands, my computer hangs up on the last command.
Do you know of any other commands i can try, to get my system to boot from a os dvd?
Thanks for your help

It means something is going wrong before the startup process gets to the stage where it can accept the startup key command input. There are various checks that happen (called POST - pre operating startup test - if I recall correctly). The firmware checks basic things like is there a processor available, how much RAM is connected, is a drive connected…
I think all the early stages are handled by the Boot ROM & NVRAM, these are generally not 'user fixable'. It indicates something is badly wrong. It could be failures in the main logic board or CPU(s) or the power management unit or possibly a dead battery (the small internal 'clock' battery is cheap & easy to replace - worth a try -> search this apple support for 'G5 YOUR MODEL & replace battery')…
Of course it could be something simple like a failed keyboard or usb hub, so try removing everything and just use the Apple keyboard & mouse and one display directly connected to the G5. You should also look for other signs such as beeps or flashes of the power button on startup, remove the outer metal door & look along the RAM slots for any lights when it gets powered on. The support site has info on what they mean.
It couldn't really hurt to try removing and replacing user-serviceable parts such as the graphics card, RAM, HD. Sometimes connections may need reseating. You will also want to remove any other PCI cards that are installed. Again the support site has instructions for all of this, sorry I would link to them for you, but I can't make sense of the model description in your posts.
An Apple service center may diagnose this for you, but unless you have Applecare they will charge you for it.

Tried to update Mac os x Maverick on Macbook Pro. Now computer will not boot

Have tried several methods, but sound comes on as if it id trying to boot, but apple on screen with little spinning wheel

What exactly did you try? Try the following things one at a time. If you have problems with running the procedures, reply back. If one of the procedures fixes the problem, do not proceed with the remainng procedures, but reply back.
Try this first: did you try a safe mode boot? http://support.apple.com/kb/PH14215 last item in the table. If successful, reboot normally and test.
Try this next: did you try to boot to Recovery HD? Hold down option key when you hear the chime and select Recovery HD. Select Disk Utility. Select Macintosh HD and click Repair Disk. Repeat the repair until no errors occur. Once there are no errors, click Repair Permissions and repeat until no errors occur. Reboot normally and test.
Try this last: did you try a single-user mode boot?
Warning: Be extremely careful when doing these steps and double-check your exact typing before you hit enter! If a step does not work, stop immediately and report back with the exact messages please
Boot into single-user mode (hold 'command' and 'S' keys when the chime sounds
At the # prompt type /sbin/fsck -fy and hit enter. It goes through a number of checking stages. At the end it will either say the volume appears to be ok or ***** FILE SYSTEM WAS MODIFIED *****. If it says it was ok, we need to do more things. If it gives ***** FILE SYSTEM WAS MODIFIED *****, redo this step until it says ok.
If step 2 does not even do the check but gives an error, please reply with the exact messages. If step 2 succeeds, report back please
Once that's done you can type reboot to boot normally and reply with status please.

Used Bootcamp to install Windows 7. Now, my macbook pro 13 mid 2009 will not boot back into OSX, there is no Bootcamp utilities like there should be anywhere to be found, and the DVD drive will not recognize the OSX install disk that came with my laptop.

Basically all in the title. Also, some additional info: partition was 115 GBs for Windows, 385 or whatever for OSX (I have a 500 GB Harddrive), I have tried restarting multiple times, and the drive will recognize the DVD, but almost as if the DVD is blank, as it asks me to format it or drag files to it, etc.

Hold your "Option" key down while starting your machine. Continue to hold it down until you are presented with the boot menu which should allow you to select either OS X or Windows (provided you didn't somehow wipe your OS X partition). When you get into OS X, you can go to System Preferences / Startup Disk. Here you can select the default startup partition (OS X or Windows)... when you're installing Windows via BootCamp, it gets changed to Windows so when you finish setting up BootCamp, it automatically reboots and launches the Windows installer. Installing all of the Windows drivers from the OS X DVD should provide you with a Startup Disk option under Windows as well.
