Intel iMac - won't start - grey screen & progress bar

I have a 2006 Intel iMac - 20" model, Intel Core Duo, 2GHz, 2GB RAM, 250GB HDD, etc. It was one of the very earliest Intel iMacs. Kept updated, running OS 10.6, etc.
It has worked extremely well for over 5 years - apart from the Superdrive being temperamental sometimes - but has suddenly gone wrong.
Last week the machine completely froze for no apparent reason. I had to force a reboot. This failed - grey screen and the grey spinning wheel (if that's what it's called), indefinitely.
Forced reboot again and this time held down the shift key to go into safe boot mode. This time it was successful, and I was able to get to the logon screen & log myself in. I opened Disk Utility & attempted to do some diagnostics but the machine froze again.
Looking around various other forum postings...I rebooted the machine in single user mode and was able to get to the command line to type 'fsck -fy' to attempt to fix disk problems. This failed repeatedly, with an error message 'invalid node structure'.
I tried to boot my machine from the OS X disc but my Superdrive refused to play ball - it would not read the disc (or any other disc for that matter, including a copy of DiskWarrior that I have).
I have now got hold of an external DVD drive in the hope that this would show up as a boot device when I switch the machine on while holding the option key down. No such luck - the drive powers up ok (power via USB) but I'm not given the option to boot from it - in fact that screen doesn't appear at all.
All that happens now on powering up - regardless of what I do - is the grey apple symbol appears and a progress bar beneath it. The progress bar gets stuck about 5% of the way along, and then after about 10 minutes it disappears and is replaced with the grey spinning wheel thingy. And then it just gets stuck - nothing else happens.
HELP!
All my important data is backed up on an external drive via Time Machine, so that should be safe, but I'm desperate to get the machine running again.
One thing that occurred to me is that I've had a program called ReFit installed on the machine which allowed me to run the machine as dual boot etc. (and I do have a couple of other small partitions on the drive, not currently used) but the ReFit welcome screen stopped appearing a couple of weeks ago for some reason. I'm wondering if this has somehow messed things up...?
Grateful for any suggestions...
Thanks,
Alan.

For the drive, you should be OK with any SATA 2 at 3 MB/s transfer speed. You could also use a SATA 1, no jumpers needed. (Not SATA 3 - can't be jumpered down.) The early 2006 Intels were 1.5 MB/s -- at least the drives were, so I'm assuming the SATA controller on the logic board was also. Might just be SATA 2 hadn't yet been introduced and can run the faster SATA 3 without jumpers. My guess is not. You should be able to set jumpers on the drive for backwards compatibility. You'll have to contact the drive manufacturer or go to their website for that info.

As for the superdrive, I'd contact the manufacturer to check on compatibility.
Glad I'm able to help. BTW, in case you haven't noticed, maybe you want to have a look here.

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

Start up screen distorted and unable to access the power slider bar

How do you force your phone to shut down - if the start up screen is so huge you can get to the power off slide bar?

Double tap the screen with 3 fingers to turn zoom off, drag three fingers to change the zoom. Then go into Settings>General>Accessibility and make sure that Zoom is turned off.

Yes, yes, yes... I've gone through all the common sense trouble shoots. Would't be here asking questions if that answers existed on the net. Sorry if I sound a bit edgey, but I've had nothing but issues with every update since IOS 7. Clearly there's nothing that can be done about this. and this is the final nail in the coffin to try to make me buy an Iphone 5.

HT4061 ipod 4th generation stuck on start up screen, won't do anything (the black screen with the silverish apple). Help?

This morning, i tried turning on my ipod (4th generation) and it is stuck at the black start upp screen (the screen that has the siverish apple when you have first turned on your device). It has been stuck like this for about a half an hour now, and I'm not sure what to do. This would be the second time in at least three months I have had problems with it (around December it went into recovery mode and i had to reset it to the factory settings). Is there anyway I can handle this at home, or do i have to go into an apple store to have this fixed? Also, I plugged it into my computer and it didnt show up in itunes like it did last time. Thanks! (I'm pretty sure its the IOS 6 because i have not updated it since then).

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I am having sporadic issues after new hard drive install and recovery using Time Machine. The same sluggish response, start up screen pixelating...If I reinstall Lion will it wipe out other applications? My HD was formatted and partitioned correctly, I have a late 2009 iMac.

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

How do I back up my MacBook Pro from an external hard drive if my macbook won't boot up from the white start up screen? HELP!

I went to the Genius Bar a week ago, and the guy helping me there was nice enough to help me save some money by telling me I could replace the bad hard drive my MacBook Pro had by myself. I bought everything I needed (hard drive, screws, external hard drive) and my computer won't boot past the white start up screen. It doesn't even show the Apple sign at the start up screen. How do I back up my computer so I can save all my music, school files, etc.? Could really use someone's advice on what to do! Thanks!

Ok, to be sure I understand what's going on. You were able to boot the Macbook from the existing "damaged" internal drive, and it has been backed up to the internal.
If that is correct, your internal drive is working. Just to be sure, try booting with the R key down. Then run Disk Utility to repair the internal drive. That drive may in fact be useable.
You should be aware that you cannot boot the MBP from a Time Machine back up.
Please post back so I am sure I am understanding the situation.

Macbook pro won't go past start up screen

i started up my macbook pro today and it opened but couldn't scroll with the trackpad. force quitted (start button) it and then tried to start up again. this time i didn't get past the start up screen (with the apple logo and spinning timer). i then tried to reset pram (cmd+option+p+r), safe mode and a number of other possibilities to no avail. next step was using the instal disc and running disc permissions + repair. again to no avail. i even tried the terminal and tried fixing the disc repair report that it was a invalid sibling link. here's a link to the procedures; http://hints.macworld.com/article.php?story=20070204093925888. i got the message from terminal that the disc is corrupted and i've now run out of tricks/options to get my macbook pro up and running. has anyone here in the community know any other avenues i could travel down. all help of course would be much appreciated. the computer affected is my new 13 inch 2.3 ghz i5 macbook pro.
cheers, Jan

instal disc and running disc permissions + repair.
You need to boot from the install disc and run Disk Utility to verify and if necessary, repair the startup disk.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
(In Mac OS X 10.4 or later, you must select your language first from the installer menu)
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your startup disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. Make sure there is always 15% free space.

Can't get past gray start up screen after failed software update

Uh-oh. I think I'm in trouble now.
This afternoon I was trying to do a software update on my iBook. After about an hour and a half, there hadn't been any progress, so I figured it had frozen, and forced it to quit. When I tried to start it back up again, it comes up to the gray start up screen, and then just sits there and spins. Here's what I've tried so far:
Safe mode- doesn't work, just sits at gray screen
Using option key- shows my HD, I select it, sits at gray screen
Using OSX installer disk- I'm able to get to disc utility this way. SMART status says verified, ran repair disk and it found no errors. Tried to run repair permissions and it just sat there for about 3 hours with the bar spinning blue and white, but not actually filling up. It wouldn't allow me to stop repair permissions, so I had to force it to stop. I thought about reinstalling, but I don't have enough space on my HD.
So, that's where I am at this point. Now I find out how I've managed to mess things up so completely, and cross my fingers that someone will please, please, please have an answer. Thanks!

I tried to backup my iBook HD using target disc mode, but it wouldn't work. The target computer (G4 running 10.4) would come up to the blue screen with the FireWire logo bouncing around, and would go no further.
I think the problem there is that you need to boot the iBook with the T key held down, not the G4(10.4). What this does is mounts your iBook's drive on the G4. The bouncing FireWire logo should be on your iBook, not your G4. This means that you connect the two machines, hold down the T key on the problem computer to mount the volumes onto the working computer.
There shouldn't be a compatibility problem because it mounts it as an external hard drive (not necessarily a boot volume.)
Will the disc come out of the iBook when there is no longer a FireWire cable connecting to both computers?
Let me know...

I clicked on the firefox update & lost my old firefox page with my aol start & quick pick tool bar & this "new" page takes up more space so when I click on a different subject, I have LESS space to view it. . Why, WHY must you people always mess with things that were just fine. . I cannot eeven restore my computer to an earlier time, NOPE, won't do it. . So now what do I do ? ? Pete . . . God Bless . . . . I WANT MY PREVIOUS SETTINGS BACK ! ! ! ! !

The problem is with the page that opens at startup?
What does the new page look like? Can you paste the address into a reply?
Or if it doesn't have an address, maybe it's a page created by an add-on. Can you see any indication of the source of the page? Perhaps you could post a screen shot of what it looks like. This article has tips on that (make sure to delete to cover anything confidential): [[How do I create a screenshot of my problem?]]
To reduce content size, try the zoom feature: hold down the Ctrl key and tap the - key once or twice. If you want to reset the page to the standard size, you can hold down Ctrl and tap the 0 key once (zero).
But really we should get you back to the page you prefer, and hopefully with the additional details I requested we will be able to figure out what needs to get changed so you can do that.

My computer won't load pass the grey start up screen

    MacBook pro won't load pass the grey start up screen?

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
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
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.
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.
Step 5
Boot in safe mode. Note: If FileVault is enabled on some models, 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 5.
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 6
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 7
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 8
Repeat Step 6, 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 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 10
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

I turned off my computer while installing something and now I only get the start-up screen with the apple logo. How do I fix this?

Reinstall OS X:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. 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.
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. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
Reinstalling Lion 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 Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
