MacBook Pro Startup Manual Boot Neccicary

I'm having some problems when I start up my Mac. If I dont manually select the boot partition (using alt/option) the startup screen stays grey for about 30 seconds, and then the text appears: No bootable disk found. Insert boot disc and press any key to boot"

Hi,
boot into OSX using the alt/option key.
Once in OSX go to System Preferences then Startup Volume and set your OSX to be the default.
On the next reboot your Mac should boot into OSX with 'help' ;-)
Btw. that error sounds to me like you tried to use the BootCamp Assistant to install Windows, right ?
Regards
Stefan

I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating sys

I interrupted a software update and my macbook pro will not boot. I have tried to reboot using the startup disc, I have tried to verify the disc, and repair the disc. It tells me I need to erase and reformat the hard drive then reinstall the operating system. I do not have a back up of all my applications, my garageband music and other things. I also do not have time capsule set up on this machine, but I do have a 2 TB time capsule.
Is there anyway to back up this corrupted drive so I can restore my applications later?

There's an old saying. If you don't have a backup disc, then there must be nothing important to backup. That's just lesson #1. Lesson #2 is to never interrupt a software update. Not a good thing.
OK, I'm sure you know this. It just upsets me to read your story, knowing you have a lot of important stuff on your hard drive, and didn't use time machine.
You're pretty much in a bad place. My only hope for you is to boot to your Installation Disc, then using disk utility see if you can save the internal hard drive (by fixing what can be fixed). You might be able to see your user folder and some of your apps. I wouldn't even consider copying the library, because who knows what's been corrupted in there.
Good luck.

How do I uninstall Yosemite please ? Since I upgraded my 2011 MacBook Pro will not boot up

My 2011 MacBook Pro will not boot up following my upgrade to Yosemite. How do I uninstall or downgrade back to the previous version of OS please ?

You can't downgrade or uninstall unless you first erase the drive. Try the following:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Macbook pro will not boot even to grey screen ??

my macbook pro will not boot even to grey screen ?? Just stopped wprking after I closed the cover.

What other indications are there, does the white light turn on, solid or pulsing?, do you hear the startup chime, or bong if you prefer. Can you hear the drive, the fans?

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

17" MacBook Pro Core i5 Boot Camp Nvidia 64 bit driver install issue

Can't get correct Nvidia driver to install on 17" MacBook Pro core i5. Windows 7 64 bit is installed and running but its using a standard VGA driver for the video card so the full resolution of the display is unatainable. I've loaded the snow leopard windows 64 bit drivers, downloaded the BootCamp 3.1 64bit drivers and installed but each time I try to run it the Nvidia part of the installer closes with the error, you are trying to use a 32bit uninstaller for a 64bit program, and it exits. I've double checked to make sure I have the 64bit driver installer instead of the windows 7 32bit installers but I still get the error every time. I then downloaded Nvidias own driver for windows 7 64bit Gt 330M and it gets the same error. Please help?

A number of people in this and other forum threads have reported problems with the Nvidia drivers when installing Windows 7 (64bit) on the new Macbook Pro (April 2010).
The problems appear to be due to an installation of Boot Camp 3.0, followed by the update to Boot Camp 3.1. As Boot Camp 3.0 does not include the Nvidia graphics drivers for the
Macbook Pro 2010, the graphics card is not recognized and the subsequent update to Boot Camp 3.1 does not complete successfully.
The proper approach consist of installing Boot Camp 3.1, which is included in the system disk that shipped with the laptop. A copy of that version was posted e.g. here
http://files.me.com/jason_fearing/an51fn. One should not use on the Macbook Pro 2010 the Boot Camp version 3.0 that shipped with the original DVD of Mac OS X Snow Leopard.
I had the same problems that were reported in the forum, when installing Boot Camp 3.0 + Boot Camp 3.1 update on Windows 7 (64bit). First I had to manually run the 64bit Boot Camp setup, as suggested by others, and then I had to install the Nvidia drivers with the modified INF files from http://www.laptopvideo2go.com/, as the graphics card was not recognized.
However when I used the proper Boot Camp 3.1 that came with the laptop, everything went completely smoothly and the installation consisted of just clicking on the setup file.

Hold Option key when starting - that gives you the option to choose between startup disks.

Macbook pro won't boot, stuck on white apple screen

Noticed today, that my macbook pro won't boot . It gets to the white apple screen with the spinner under the apple logo. It stays like this for a long time without doing anything except spinning.
I've powered down and tried to boot up several times.
I have boot camp and windows on my mac and when the white screen appears, I can press Option to bring up which hard drive and the Windows partition will load without any problems.

Exacty what happens when you try to boot up from the disc that came with your computer? Are you holding down the c key? Have you tried holding down the "option key?" Are you able to run the Hardware Test - Intel-based Macs: Using Apple Hardware Test
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Lion - This will install a "fresh" copy of Lion without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

My Mid 2010 MacBook Pro will not boot

My Mid 2010 MacBook Pro will not boot regularly, in safe mode, in recovery mode or from original OS DVD. Is this the logic board?
I've tried resetting the SMC and pram numerous times and even tried switching out hdd's to try and do a clean install on a new hdd.
If I attempt to boot regularly or from recovery drive the grey apple logo appears for a period before the screen goes black and the power LED operates as though in 'sleep' mode. I'm unable to wake it from this state and the same applies to booting in safe mode.
When attempting to boot from the OS DVD that was originally packed with the computer it just freezes on the language select option, this occurs with the other hdd's I have attempted to use.
Any other suggestions to get it working? I fear the logic board has gone and that the repair won't be worth the money.
Thank you in advance.

Hi JRC8.8,
It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

MacBook Pro will not boot up

Hello,
My three-month-old MacBook Pro refuses to boot up. The problem began about two days ago, and since then, the situation hasn't changed. When I press the power button, the Apple logo on the boot screen appears, but it quickly flashes on and off, with a "no symbol" and a symbol consisting of a folder with a question mark on it flashing at random concurrently. I really need my MacBook Pro to boot up, because I require it for homework that is due tomorrow. I have never dropped or even scratched this computer, and I always use it in a cool and dry environment, so I don't think it could have been anything to do with overheating. But I'm no expert. Does anyone know what I can do? Thank you so much, in advance!

Usually the flashing question mark means that the computer can't find a bootable device. Your hard drive may be damaged.
Try booting into your Recovery partition, holding down the command and R keys whilst booting. Use Disk Utiity to both verify ad repair your hard drive. If the drive cannot be repaired, called back (you can access Safari from the Recovery partition).

Macbook Pro Will Not Boot Windows Disk

I have a late 08 (or early 09) Unibody Macbook Pro 2.53Ghz. I start the Bootcamp Assistant and successfully create my Windows partition. When I restart with the Windows 7 disk, I get a blinking cursor for 1 second then it goes to a black screen and never leaves. I have tried several different Windows 7 disks with the same result. I have even tried booting from a Windows Vista, Windows XP and even a Ubuntu disk all with the same result, stuck at a black screen.
I took the hard drive out of this mac and put it into my wife's older Macbook pro, and it booted off the Windows 7 disk and completed the install to the drive with no issues. I then put the hard drive back into my Macbook Pro and get the same black screen when trying to start the Windows partition, and still have the same problem that it will not boot from any other OS disk be it Windows or Ubuntu. It boots from OS X DVDs without a problem.
Also several months ago I had a Windows XP installation on this computer with no issues. I wiped it just before going to Snow Leopard.
Any clue as to what is going on here?

What is really odd is if I take my hard drive out of my Unibody Macbook Pro and put it into my wife's non-unibody Macbook Pro, it boots the Windows partition with no problem (Remembering I previously swapped these hard drives to complete the Windows installation to my hard drive). Seeing as the disk boots on her machine fine and not in mine, and my Windows cds (DVDs) boot fine on hers and not on mine, it seems to me it's something specific about my machine, but I can't imagine what it is.

Mid 2006 Macbook Pro won't boot (from HD or optical)

My mid 2006 Macbook Pro will not boot from the hard disk, or from the internal DVD. I am currently running the latest version of Lion (10.7).
I tried searching the forums and found a similar issue here:
https://discussions.apple.com/thread/1687899?start=0&tstart=0
But that was with a Mac Mini. And it doesn't look like the OP issue was ever resolved. I am having the exact same problem.
When attempting a normal boot from the internal HD of the Macbook Pro. It will make the happy chime of a successful POST. It will display the Apple logo. And that's as far as she gets.
No spinning wheel, no error image, no nothing. Eventually the system will start spinning up the fans as if it were under load (this was after about a half hour of just letting it sit there).
Doing a verbose boot, it never went past this:
com.apple.driver.Apple.IntelCPUPowerManagement
Photo of verbose boot:
Here's what I've tried.
1. Bought a brand new battery (as the current one was at death's door)
2. Zapped PRAM (Apple + Option + P + R)
3. Reset SMC according to these directions: http://support.apple.com/kb/HT3964?viewlocale=en_US
4. Attempted to boot to my original Tiger (10.4) install DVD, only to stop at this point during a verbose boot (Apple V):
Extension "com.apple.driver.AppleACPIPlatform" has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style
Photos:
5. I am able to put her in Target Disk Mode (hold T at boot). Then with a firewire cable I can connect it to my wife's Macbook 13" and I am able to run disk utility on it! Disk Utility did find and repair errors, however, it still refuses to boot.
6. I attempted to boot from my wife's Macbook 13" in Target Disk Mode. I put her machine in Target disk mode. Connected the firewire cable. Powered on my 15" MBP while holding the option key. Then I selected her drive as the boot disk... however it still refuses to boot even from a known working HD.
7. Finally, I swapped around RAM DIMMs with no change in behavior.
Help! I know she's an older gal (Laptop is 6 years old now) but I'm not exactly flush with cash and would rather not give up on her just yet.

My Mac started freezing (colored pinwheel) every time I tried using any application (i.e. Safari, iPhoto). After restarting for the 2nd time, it would no longer boot - makes start up sound but gets stuck on gray screen w/ apple icon. I tried resetting PRAM also - did nothing. I decided to reinstall OS; problem now is my HD is nowhere to be found! I am a tech dummy so this is way beyond my comprehension...I'm not seeing my HD from the Disk Utility either???
Side question...I backed up my files (mostly pics JPEG and videos) on DVD (had to compress to save). Why can't I open files on PC?

Macbook Pro will not boot beyond grey screen. System freezes.

My Macbook Pro will not boot-up or get beyond the grey screen (with spinning gear wheel.) I've tried all the recommended actions: resetting PRAM, disk repair, permissions repair, re-boot in safe mode etc but still the problem persists. When viewing the safe-boot in verbose mode, the system seems to hang at the stage when it's checking the Airport & Ethernet - the last line on the page reads: "AppleBCOM5701Ethernet: 0 0 setFixedSpeed - logic error, speed any?"
Any ideas how to fix this without doing an Archive & Install?
I'm assuming that if I do an "Archive & Install" then I will lose all my Applications (VLC, Handbrake, MS Office for Mac etc.) Will this actually be the case? Will I lose them.
Any help gratefully received. Many thanks.

Archive and Install just affects the System files, so any apps you have should still be available afterwards. The Installer on the disk that came with your Mac, when you bought it, will tell you this before you proceed. Of course, you can always back out of the Installer if you feel chicken.
Notwithstanding it is still necessary to backup everything. You need to check that Time Machine is set to also backup your Applications folder. It might be set not to do this.
It may not be necessary to worry about this if you have the original installer disc(s). I think any stuff downloaded from iTunes etc can be re-downloaded. However, it's probably quicker to get Time Machine to backup your apps if you can afford the HDD space. It's bound to be quicker than re-downloading the stuff plus any updates. And of course there's those Apps that you have but forgotten about. What about them?
