Mac book not starting - renaming of Mac HD

I installed Leopard 7 days ago and have been having no significant problems until this morning when the machine would not start.
The "chord" sound plays, and the Apple Logo on the grey screen shows, along with the little spinning indicator, but it goes no further. I am stuck, and in the middle of Sudan without any real tech support folks anywhere near.
I have one candidate so far for the source of the problem:
1. I suspect that this may relate to my renaming of the hard drive last night. As to why I did such a thing, nevermind that.
Any ideas about how to get the machine to fully boot up? and perhaps rename the drive again to the original?

Oh! I was hoping it gives you two drives / images, and one of the would be the corrupt one. What this may indicate, i am afraid, is that your boot volume has been somehow corrupted.
Did you rename the boot volume via the "get info" window in finder? Because this should be fine.
The only way to go further - alas - is to wait for the computer disk to arrive. And maybe run disk permissions from the disk (you would need to go past the window "installation language", which then gives you a simplified finder bar, where disk utility can be run from. ). if that then finds a disk called e.g. "WD5000AAKS-41YGA0", RATHER than your own disk (e.g. "jubas very own" or whatever you named your drive), then your volume header is probably corrupted, and it cannot access the info. you could try a "repair DISK", then hopefully afterwards "repair disk PERMISSIONS".

Mac book not starting up after update

after installing the latest update on Mountain Lion my Retina MBP dies after trying to boot. any help would be great.

Hopefully you have a backup. Your hard drive may be failing. I'd try a few things:
if you have any peripherals, like mice or keyboards, unplug them and try again.
try a SMC reset Intel-based Macs: Resetting the System Management Controller (SMC)
a safe boot Mac OS X: What is Safe Boot, Safe Mode?
boot to your recovery partition and repair your hard drive and permissions When to Run First Aid in Mountain Lion's Disk Utility - For Dummies
if that doesn't work, try internet recovery OS X: About OS X Recovery
if you can get your computer booted in one of the recovery modes, but it can't be repaired successfully enough to start into the regular boot partition, you may need to erase the drive and start over with a clean installation.
You might be able to get your hard drive to mount in target mode on another mac, which would let you back up any files that you want to save on the drive: OS X Mountain Lion: Transfer files between two computers using target disk mode
if you can't get any of this to work, then the drive quite possibly is failing, and should be replaced.

Mac book not starting it's showing question mark

Can you help me

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

On Mac Book Pro start button does not turn it on.

On Mac Book Pro start button does not turn it on.
After some attempts of pressing it finally it turns on.
(Meantime keayboard can be highlighted,but screen is black and I hear noise of shutting down it when I press it).
What can be the cause of this problem? Actually MacBook is new,only 9 months.
Please give me some suggestion what should I do.

It will be complicated to take it to the Apple store as in Georgia (Caucasus)there is not official Apple stores and in addition Mac Book was purchased in UK. I have red some staff here about start button pressing hard for turning it on, I have feeling that now it needs to be pressed hard to turn on. If it would be from the beginning I might think that it's normal,may be,for Mac Book,but initially it needed to be slightly pressed.
Thank you for suggestion.

I can't Install my updates on my mac book , it starts to install and a box pops up saying i don't have permission to installpermission

I can't Install my updates on my mac book , it starts to install and a box pops up saying i don't have permission to install

So, then, after you click the Install button you receive the permissions error dialog? Again, are you logged into an Admin account?
Have you tried:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Also, please check the settings on your startup drive. Select it. Press COMMAND-I to open the Get Info window, then open the bottom-most panel and check the settings. They should look like this:

HT1349 why does my mac book pro start up but contunitues to try to load

can someone help with my mac book it starts up logo appeares then the busy signel conuines to try to load but nothing happens?

Try starting your Mac in Safe Mode.
Restart your Mac.
Press and hold down the Shift key immediately after hearing the startup tone. Be sure NOT to press the Shift key before the tone.
Release the Shift key when you see the Apple logo and the spinning-gear appear.
When the Login Window appears, log into your account.
If you Mac starts up, then the issue may be a problem with one of the Startup items, Login items, or a 3rd-party kernal extension (if you got a kernal panic screen during startup.)
If your Mac does not start up, use the Startup Manager to see if the startup disk is detected. Note: By default the startup disk is Macintosh HD.
Try running the Apple Hardware Test. This test is included on the Installation CD that came with your Mac.

I have a 17" Mac Book Pro and a 13" Mac Book Pro...both use the same Apple ID. My wife now wants to change the Apple ID on the 13" to her Apple ID. How do I do this and not loose the information on that computer?

Hello Teddy53149 and welcome to Apple Support Communities,
Follow this procedure:

As they recommend and as always when you're messing with administrator accounts back everything up first.

EyeTV: Mac does not start automatically

Mac does not start automatically for EyeTV recordings. I reinstalled EyeTV but it did not help.
Any help appreciated.
iMac i5, 2,7Ghz, OS X 10.7.4
Kind reagards,
Torsten

I have to same problem: Bought Elgato Sat 3 years ago. Now I decided to install it in the living room and bought a new i5 Mac mini. EyeTV works fine but does not wake up Mountain Lion 10.8.2 sometimes.
When I program wake up events manually via System Preferences or pmset command in the terminal, all works fine and my Mac wakes up. I tried everything, from clean reinstall to debugging AutoWake.plist and such.
Annoying!

3 year old Mac will not start up, help?

My 3year old Mac will not start up, just sits there and spins. Any suggestions on corrective steps?

Kurt412,
which version of OS X is installed on your MacBook Pro?

My Intel Mac does not start.

My Intel Mac does not start. When I turn it on I hear a loud beep (a sound I never heard before) and then I see the spinning wheel and nothing else. I tried to start from the installation disc, I also try to reset the SMC and the PRAM. Nothing worked. I replaced the RAM cards too. It is a IMac 24"/2 Intel. Model number A1200 2006.

When I turn it on I hear a loud beep
Beeps are an indication the RAM (memory) is failing or has failed.
Power On Self-Test Beep Definition - Part 2
If you feel confident doing this, you can purchase RAM online. Crucial comes highly recommended. You can use their scanner > Memory upgrades from Crucial.com - Crucial Mac System Scanner
And uninstall the bad RAM, then reinstall new > iMac: How to remove or install memory
Or, take your Mac to an Apple Store.
The beep sound is not permissions related.

My I Mac does not start properly without pressing option and apple keys ,and it freezes

My I Mac does not start properly without pressing option and apple keys ,and it freezes

Try any of the following:
http://support.apple.com/kb/HT1379 Resetting your Mac's PRAM and NVRAM
Disconnect all devices from the computer then do the following:
Boot up from your Snow Leopard Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

Mac does not start is asking me to reboot from back up

My Mac is not starting and is asking me to reboot from the time machine however it is showing me that the latest complete backup is form September. Should I reboot from there and once I am in I will be able to rescue latest backups or should I re-install the OS? If I re-install the OS will I loose everything or will things still be there, including folders that were loose in the desktop as opposed to being inside the hard drive?

Time Machine is not bootable.
Is it asking you to Restore from Time Machine?
Re-installing the OS X on top of what you have will preserve all files, photos, documents, settings, bookmarks, history etc this includes items on your Desktop.
Recovery http://support.apple.com/kb/HT4718
From Recovery you can also run the Disk Utility>Repair Disk to see if there is a problem, this may sidestep the need to Restore.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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 installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
