Just got snow leopard install failed now Mac will not boot up?

I got a iPad and snow leopard very excited to use them I try to install leopard and it fails so I turn on the comp to try it again and I get the apple logo then the spinning wheel then it just shuts off and that's all it will do now!
Glad I got the iPad so I could post this!
Anywho I've tried all the command option P+R stuff so any other suggestions would be great!
Thank you

Try inserting the instalation DVD provided by Apple and start the computer while holding the 'c' key down on the keyboard until you hear the DVD spin and some action in the DVD drive. If your mac doesn't start and show something meaningfull then, take it back to the shop it has a hardware problem, or your installation disc has.

XP Pro install failed now I can not boot to Mac OS

So I was installing XP pro on my 17"MBP and had it fail... (no big deal)
I did it all through BootCamp (had made the partition ages ago).
Had the disk in ran things as BootCamp told me.
Was going then when choosing the instalation drive it only showed my main drive and wanted to reformat. Now I know that the BootCamp partition was there because I have been staing at the thing for a month. I told it to ESC.
It asked to restart (OK)
Now my mac will only boot to the dead Windows Partition.
Holding Option only gets me windows as an option, unless I have an istall disk in... then it lets me chose windows or the disk.
I don't need XP and was only doing it to sink with my GPS, darn me for trying to make this work.
Any clue?
I am having to post this from my iPod touch so searching for other posts with the issue was a challenge.
Thanks and Sorry

Having same problem as this guy but with my iMac. Formatted the one and only choice of 131gb partition (having made one with boot camp beforehand 32gb) but now am in an endless cycle of cancelling the install but rebooting the windows setup from the CD which I cannot eject

Snow leopard install and now can't find boot camp

I just installed snow leopard in preparation to use the latest version of boot camp. When I completed the install, boot camp was gone.
Can someone tell me what I need to do?
Thanks

Did you repartition the drive? Or are you referring to the application, Boot Camp Assistant?

Am running Tiger 10.4.11; just got Snow Leopard 10.6.3 (regular OS disk, not an upgrade); when I install Snow Leopard, will it wipe everything? overwrite Tiger? Do I need to make backups of applications and files to reinstall after Sno Lprd loads? thx!

Hi Donald,
No it doesn't erase anything by default, it does what we used to call an Archive and Install feature, which can give you a new OS, yet preserve your files and settings if you have enough room on your HD...
http://docs.info.apple.com/article.html?artnum=107120
But it does it automatically unless you specifically erase the Disk, but will replace Tiger completely for the OS & several Apple Apps like Safari, Mail, etc, yet preserve your old settings for those!
If you think you may need Tiger to run any APPs that do not work in SL/10.6, then clone or backup first.
I would recomend 2 things before installing though...
Make sure you have enough RAM & HD space.
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 2GB at least)
    * 5GB of available disk space (I say 30GB at least)
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
"Try Disk Utility
1. Insert the new Mac OS X SL/10.6 Install Disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."

Just had Snow Leopard installed. Iphoto won't open. I'm supposed to photograph 300 people on Friday.

I have no idea why Iphoto won't work. The icon bounces once, and then does nothing although I see the details at the top of the screen.
I've used it extensively since I had Snow Leopard installed last week. Did not upgrade to iphoto11 after much negative feedback from my photographer pals.
I did notice that when I opened a couple of photographs to edit them that once in a while a green or red background appeared, but it was random and only happened on a couple of photos.
I have tried Shutting Down the computer, force quit iphoto a few times........Nothing.
I am 3 hours away from an Apple store and have the largest assignment of my year in less than 48 hours.
Can anyone help me out? Many thanks.

Thanks for sharing so much of your life story, though I'm not sure what relevance it has to your issue, which, I believe is that you can't open iPhoto.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Mac will not boot from hard drive or install disc

Hello All
In dire need of advise...my intel Mac will not boot, even tried booting to the Snow Leopard install disc and all I'm getting is the white screen, apple logo and the wheel.
Just before this happened there was a buzzing sound like the fan was about to fail but that is only a guess on my part. Is there a keyboard shortcut to boot to a terminal window or similar to force the computer to boot from the install disc.
Thanks in advance for any help offered.
Warren

Hi Warren
Try holding the Option key and see if it will boot into Startup Manager, where you should be able to choose from a good Drive or your install Disk.
http://support.apple.com/kb/HT1533
or the D key and run the Apple Hardware Test.

Also note: key commands may require a USB Keyboard if your using a wireless and it has become unpaired.

I have the i phone four and just uploaded to my computer and now it will not work has the apple logo with a long oval bar under it

It may be that it is stuck loading. You will want to probably first attempt a Hard Reset (Home Button + Power Button for 5-10s until it restarts with an Apple Logo then let it load up) and see if this will get it working.

HT3053 I removed battery without turning off computer, now it will not boot up or eject cd

I removed battery without turning off my mac book pro. Now it will not boot up or remove cd. I tried restarting with eject, spacebar, command e, option, trackpad, and f12 depressed, individually each time to no avail. I installed a 2 gb. ram kit and loaded OSX Snow Leopard after removing battery. I tried reinstalling the old ram with no luck..................Any help or suggestions would be welcome...........Thank You!

And you eject the CD by holding down the mouse/trackpad button before powering up; that is, before the startup chime.
BTW, if no startup chime or a different melody, RAM ist kaput.

After 10.5 upgrade Mac will not boot from hard drive

I just upgraded to 10.5 Leopard but my mac will not boot from the hard drive even after selecting my hard drive as the startup disk. The mac will start to boot but will cut itself off before the boot is complete. I have to leave the Leopard disk in the mac and hold down C to get the mac to turn on but it only allows me to install the software again.

instead of archive and install you might first want to try restoring your system using TM to some time point before your failed 10.5.1 upgrade. Then try upgrading to 10.5.1 again. I would suggest downloading the full 110 MB upgrade and installing it manually rather than doing it through the software upgrade menu.
You can download the upgrade here:

I took my iMac 2010 to a "Third Party" company to replace my hdd, they did, but now it will not boot. if i took this to the Apple store, how much would it cost to fix? if i buy my own SSD (£70) Thanks a LOT!

The way I read that comment – you seem to suggest the Mac was broken before the third party replaced the disk - is that the case or was it working before the HD was replaced?
Since the Mac is out of warranty you will have to pay for any repairs wherever you take it. Authorised Apple service centres will be able to get parts whereas any non certified technicians will have to use 'grey market' parts since Apple will not sell parts to the public. These may be reconditioned or not official parts - it's a risk to use them. Visit the Apple store & ask them - there is no point in lying about it being handled by a third party. An Apple tech may be able to tell when they open the case, depending on how meticulous your third party was.
If you are handy with a screwdriver & have tools and a lot of patience you could use a guide on iFixit.com, but there is no indication of why this Mac not booting up.
It could be that the disk is not formatted correctly.
Are you sure the tech copied an OS onto the disk? Did they install the OS for you or did they clone the old disk?
Can you boot from a backup disk or from an install disk? Does the disk appear in Disk Utility when booted from another OS (either the installer or a backup).
'Not booting' can mean so many things, what does booting do exactly? Grey screen, black screen, any noises or tones, any signs of life at all…?
If you look at the iFixit guides you will see many fiddly connectors, if the tech failed to hook them all back up it could explain the failure, or perhaps you just have a disk that is 'dead on arrival' - sometimes that happens. A properly trained technician should be able to figure that one out.

Thanks for you response! I have had it for about 5-6 years ... don't know if that is "vintage" or not. I just got back from our local Geneis Bar and they declared it "DOA." So, I've got a new one and getting ready to install. Thanks, again!

Mac will not boot up, white screen with turning gear for hours on end

mac will not boot up, white screen with turning gear for hours on end

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in 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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 9
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Mac will not boot up

My mac will not boot up - shows a sort of stop sign then grey screen

What Mac, with what version of OS X?

I have reset my ipad using General Reset Erase All Content and Settings. And now it will not boot. All i see on screen is the Apple logo. What do i do?

I have reset my ipad using General > Reset > Erase All Content and Settings. And now it will not boot. All i see on screen is the Apple logo. What do i do?

When you restore, you can restore to factory settings or to a backup. Restoring to factory settings removes everything and takes you back to out of the box status and you start all over again. Restoring from your backup will replace all of your app data, bookmarks, email settings and things like that. You still may need to sync all of your purchased apps and music, photos and so on back to the iPad.
I assume you want to restore from your backup to put all of you data back on the device so connect the iPad to your computer, launch iTunes, right click on the device name on the left side under the devices heading and select restore from backup. After you restore from your backup, make sure that you sync all of your other content with iTunes.
