MBP 2006 won't boot?

Problem:
Suddenly, I try to boot, but I get spinning gear under the apple for a long time, then, spinning gear on bluescreen for quite a while, then blue screen, blank, then blue screen with moveable cursor.
Background:
I used it successfully all morning, burning discs with an LG external op drive, no probs. I installed any video converter for intel mac. I powered down and when I rebooted, above symptoms.
I have tried:
Reset PRAM/NVRAM (?) (held down cmd/opt/p/r at boot for 2 chimes), tried a safeboot (didn't work), and I tried starting from the inst. disc (held down "c") (didn't work)
Stuck on blue screen with cursor, no light on lid release button until I close the lid, but doesn't sleep(?) (not fading in/out of light) then no display when I reopen...
What to do now?

Update:
I'm hoping all hope is not lost. I was able to "boot to the CD", tried to Repair Disk, says "Invalid Extent Entry", and "Disk cannot be repaired"
Tried an Arch and Inst, be failed after verifying the Install Disc, said, "Try again".
Any help is appreciated. BTW, I got to the disc by holding the Opt. key (not C) at start..? Saw Macintosh HD and Install Disc, chose the disc and Utilities menu for Disk Utility.

MBP 13' Won't boot from CD or external Drive

Recently my MBP 13 (newest version) occasionally crashes with the grey screen death which forces me to hard shut down. This led me to believe my directory may be corrupted so I tried to boot from my external OS X (Snow Leopard) with DiskWarrior installed to do the repair. Unfortunately, when the grey Apple logo shows up, the computer crashes again.
I tried again using original recovery CD to boot hoping to use Disk Utility, but it does the same thing where it crashes at the Apple logo.
I can't seem to figure out why. Anyone have experience with this issue? how do I resolve this issue???!
Thanks

This could be why it won't boot to it. It may not have the correct drivers to run the 13'. You really should have a clone of each Mac you own. Perfect for trouble shooting this type of thing. You can partition an external to have clones of several different Macs. I do that, plus I clone each to an extra internal on the desktop models.
However, if this have any impact it should've occurred in the past?
I think you just got lucky in the past.
I just spent 2 hrs re-installing OS X again and restoring. It's still doing the same thing. (It appears I can boot from the restore CD, but not external drive).
What install method did you use please?
If you can boot from the DVD, go to disk utility and see what your internal drives S.M.A.R.T. status is. Might as well run a Disk Repair while you are there.
Also, since you can boot from disks,
I would try running the extended version of your Apple Hardware Test.
It's not perfect but may flag something.
I'm assuming you can't boot from your DiskWarrior disk cause it's an older version that won't boot the new 13'?
That's the case for me and my MacBook. Since you can't boot to your bad clone, do you still have another Mac around? If so, you could boot in Target Disk Mode and use Diskwarrior from the other computer to try and repair the 13'.

MBP MA610LL won't boot with a working drivem but powers up

I have a MBP that powers up and won't boot. I swap HD with a friends drive (same system) and it still won't boot. Any ideas? Bus problem? Bad RAM? Should I sent to tech support, but I have don't have the service plan.
Any Ideas?
Thanks!

Welcome to Apple Discussions!
Can you boot from a disc? One thing to try is to hold down "D" while starting up and try to boot from Install Disc #1. This should get you to the Apple Hardware Test. Run the extended version of the test--it will check your hardware, including the RAM. If you have a hardware problem, like bad RAM, it will give you an error code. If you get an error code, please post back with it.
If you do not get any error codes, eject the disc. Then boot from it again, this time holding down "C" as you boot up. Navigate to Disk Utility, click on your hard drive by brand name, and go to the First Aid tab. Verify and repair if possible both permissions and the disk. This may take a while. Post back with how it went.
If you have access to an Apple Store, you could also make an appointment with the genius bar and take it there. This won't cost anything just to talk to the genius, and if you get a smart genius, he might be able to figure out what is wrong and what to do about it. If you decide to do this, go ahead and run the AHT first and bring along the discs that originally came with your machine.
Good luck!

Macbook Pro (Core Duo Mid 2006) won't boot

My macbook pro won't boot. I'm suspecting that the HD has gone out again, but I also don't seem to be able to boot from a CD. When I startup, it gives me a grey apple screen with a spinning gear. I tried running disk first aid from the command line and it said the B-Tree was corrupt and could not be repaired.
What has me confused is that I am also unable to boot from a CD/DVD. When I startup with a CD in the drive, it spins up and then ejects. If I insert it again, it spins up again, then spins slower, but I can still hear it spinning and just hangs. It seems to make no difference if I hold the C-key or not. I have tried 3 different MacOS X disks and a DiskWarrior disk all with the same result.
I've also tried zapping the PRAM and letting it sit unpowered with the battery out.
Leading up to all of this, the computer got very slow.
Any ideas? I'd like to have a feeling that my CD/DVD drive isn't broken before I spend any money on a new HD. The computer is 6 years old, but I'm just not ready to spend another $1-2k on a new one.
Thanks

You got 6 years out of it, it's 1.5 years past average of 4.5 years, hopefully it's a software issue.
Run through these User Tips, it's for 10.6 which you should be on (call Apple via phone for the 10.6 disks) and give it your best shot to extend it's life a bit longer.

MBP 13" Won't Boot, Gray Screen w/ ? Folder, Hard Drive is perfectly fine

I have a 13" Macbook Pro that won't boot up. When I used my install disk to get to disk utility, it did not recognize that there were any drives in the computer.
I tried:
Removing the hard drive and plugging it into another computer using a SATA to USB adapter. It worked fine and I could see all of the files on the hard drive. I ran the disk utility on another Mac to see if there were errors. It found none. I then restarted the other Mac and selected to boot from the USB drive and it booted perfectly fine. I tried reconnecting and seeing if it would boot now for some reason (machines are funny like that). It didn't; same problem.
Next, I tried:
Installing a different hard drive to see if the disk utility program would see it. It did not.
Then, I tried:
Connecting the original hard drive to the defective Mac using the SATA to USB adapter and trying to boot from USB. This worked fine.
Conclusions so far:
-The Hard Drive is 100% ok
-The Hard Drive Cable MAY be defective
-If the Hard Drive Cable is not at fault, there MAY be a problem with the logic board.
I was wondering if anyone has any further ideas for me before I try swapping out the hard drive/infrared cable?
Any thoughts would be appreciated. Thanks.

I have pretty much the same problem, although I don't get the question mark, I get the gray screen with a symbol like a "no entry" sign. In other words, circle with a slash through it. Very odd. Never seen that before. I booted from two different external drives and the computer boots fine. The internal drive mounts on my desktop and is accessible, nothing is wrong. I cloned the internal drive to one of the external drives and booted from that fine as well.
The disk has been repaired via Drive Genius. I rebuilt the directory through Drive Genius and it seems to run just fine.
It seems it may be as simple as a bad or loose cable, but since the icon is something I'd never seen I wanted to see if anyone knows what that icon might mean. The only new thing I did last week was defrag the drive through Drive Genius.
Oh also, I replaced the battery last year from OWC. The glue holding the silver outer plate has come off so that battery, though working fine, is a bit of a pain. Since the battery is lose inside that casing, I was wondering if maybe there is a strain internally. I don't know the wiring that's near the battery connection.
Thanks for any help

Mac Pro 2006 won't boot after attempted cpu swap, Mac Pro 2006 won't boot after attempted cpu swap

I just picked up a used Mac Pro 1,1 (2006). It has 2x2.0 GHz dual-core processors and 5GB of RAM with the 7300GT card.
In this configuration, the machine was running perfectly. I, of course, wanted to upgrade....
I ordered a pair of 5160 3.0GHz processors cheaply and followed a video tutorial to install them. I used Arctic Cleaner and Arctic Silver 5 for the thermal paste.
Bottom line is: I installed the two new processors and when I fired it up, I could hear the fans, optical drive and hard drives all spinning (normal fan speed - NOT "jet mode", and the HD sounds like it's spinning - NOT like it's booting). NO boot chime and NO display. I popped the cover off and saw the CPU B FAIL light on. I swapped CPUs to test the processor, expecting to see the CPU A FAIL light come on. It did not. It just powered the fans/drives with no result (again, with no boot chime and no display).
To make a long and frustrating story short, I wound up putting one of the original 2.0GHz processors in slot A, leaving B empty (maybe I damaged the socket?) and IT STILL WILL NOT BOOT. I have tried all of my processors - the original 2.0GHz and the new 3.0GHz ones - with the same result. There are NO symtoms or indications - no error LEDs, no beeps - no indication why this machine will not boot.
I have reset the SMC, pulled (and replaced) the coin battery, and left it unplugged for over an hour. I have re-seated everything I can think of.
As of rigt now, I can hear the fans quietly humming with the optical drive making a quiet "click" sound as it seeks for a disk to read, and I can hear the faint chatter of the HD head. The power LED is nice and bright (no flashes or pulses), and there are no red LEDs on inside the case. The memory LEDs flash once during bootup and that's it (it's the RAM the machine came with). Pressing the DIAG LED button tells me the machine has power (green LED), has trickle (yellow LED) and the GPU light flashes green.
Of note, during the swap, I got a tiny bit of thermal paste (non conductive) on the contacts of my 2.0 CPUs - which I cleaned off with alcohol and let dry. The gold contacts all appear to be good on the original processors. I can't really see the tiny little pins in the CPU sockets (my eyes are not as young as they used to be!), but the "look" like they're all there.
I'm going to leave this unplugged overnight, but does anyone have any ideas?? If I managed to somehow destroy ALL of the CPUs, wouldn't I get a warning LED or beep or something? Ideas are welcome, as I cannot afford to replace this machine - it has to get me the rest of the way through college.
thanks
Richard

Hello Grant
>
Hardware sets the fans to maximum, and only properly-operating software resets them to "normal levels. If you have fans at normal levels, some software is running.
>
That's what I was thinking, but I'm not even getting the startup chime, and the HD sounds like it's powered on but not doing anything.
EDITED TO ASK: what software could be running at this point? Nothing has loaded from the HD, that much I know...
>Do you still have CPU A or CPU B failure lights?
No. I have just one original processor installed in the CPU A socket. No lights of any kind. (Even if I install an original processor in CPU B, I still occasionall will get a CPU B FAIL light, so I'm thinking I damaged the socket somehow...the light will not be consistent, but it's always the CPU B FAIL light - the light only turns on some of the time (and stays on once lit) - so that's why I pulled the B processor and am simply trying to boot with A alone)
>Do you have a flashing power on light, indicating failed or no memory?
Again, no. I can "make" the light flash by removing the memory riser, but when I re-install the riser, the light stops blinking (with power off during removal/install, of course!)
>Have you done the more severe SMC reset with the reset button OR:
unplug AC power.
Yes. I have used the SMC reset button 3 or 4 times. I unplugged the machine and left it (with coin battery installed) for an hour. The last thing I did last night was that I left it unplugged overnight (with coin battery removed). I have yet to attempt a power on this morning. I will do so and report back.
>
unplug AC power.
Press and hold power-on for a quarter minute to drain the power capacitors.
Re-plug AC power.
wait a quarter minute.
then power on.
>
Haven't done that one yet. (Didnt know about it!). Will try that second today, after attempting the initial boot up after leaving it unplugged all night. (fingers crossed) Of course, the capacitors are likely discharged now after being unplugged and battery-less all night, but you never know...
>Many things have to get synchronized after a CPU swap. It may take a half-dozen reset attempts before everything lines up again and goes.
Thanks for the hope. I will keep trying.
>
I recommmend you remove ALL distractions: all drives, all graphics cards, all PCI cards, all USB devices -- until you get the chime nothing else matters.
Already have done so. Last night I was down to 1 original CPU (CPU A), one memory riser with 1 set of original 1GB DIMMS, 1 bootable HD and nothing else (not even a keyboard/mouse - literally NOTHING else). Will keep trying in this configuration. All I really wanted last night was to hear the "bong" at power on!
Will do a bit more troubleshooting today and will report back.
Thank you!

Mac pro 2006 won't boot after lion install

hi,
under 10.6.8 everything worked fine. All adapters and peripherals were functional.
After a normal looking lion install my mac pro 2006 will not make it past the boot screen (Grey Apple logo with spinning wheel). After a while the spinning wheel stopped spinning but I hear disk I/O continue for some time. A verbose boot lists the usual output. The last line visible has a mention of macos_swapon or something like that. I do note the first couple of lines specify a 64 bit kernel is booting. I was under the impression that this machine cannot run the 64 bit kernel from snow leopard discussions.
The video card is an upgraded one (i.e. not the stock card that came with the machine). However as I said before it was working fine under snow leopard.
Any ideas?

I have the same problem. I did a clean install of Lion and created a temp account. I was able to use Lion for a bit, then I used the Migration Assistant to bring my regular accounts back in from an external drive. When that completed I logged off of the temp account and into my main account (without restarting). Still no problems, Lion was working fine. I shut the Macbook down for the night. Now that I'm powering it on the next morning, I only get the Apple logo and spinning wheel.
I tried a PRAM zap, but it didn't help.

My MBP Retina won't boot!

I turned off my mac last night while Time Machine was still backing up my files to my external drive. Turned it on this morning but then it won't get past the apple logo with the spinning progress circle. Tried to boot into safe mode but then the bar only gets filled to a third then the spinning circle comes up again. After 45 mins, it's still stuck at the circle. Used internet recovery then disk utility after to check my drive but then it says it's okay so I restarted it by clicking the apple logo at the top bar. When I hold cmd+r at startup, it immediately goes to internet recovery. Tried resetting the nvram thing, too, but that didn't help. I do have time machine backups but the files I need weren't backed up. Any suggestions on how to get past the spinning circle without using those? I'm desperate. Any help would be appreciated.
Btw, the backups are on my external drive.

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
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
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 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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 damaged 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 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
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 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to 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.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
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 backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
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.

Intel Mac Mini from 2006 won't boot up! Shuts off by itself.

I stuck a copy of Snow Leopard into my computer to upgrade it before realizing that there were certain things I hadn't thought to back up before I did. I tried to exit the install process by selecting the appropriate start up disc and then restarted. It took forever and ultimately just shut down. I turned the computer back on and it kept taking me to the os install screen until eventually it started shutting itself off before I even got there. I finally got the disc out of the mini by holding down the mouse button as it turned on, but I still can't get it to boot up into the usual os. When i turn it on, I get a blank screen, eventually an apple with the round symbol that something's loading and then eventually it shuts off before I get anywhere.
Can someone PLEASE help me? It was a dumb mistake, but I really need to get back into my computer. I reset the PRAM, but that didn't make a difference. Thank you in advance if anyone has any advice.

If you have the 10.6.3 disk you're in luck.
All you do is pop it in the DVD drive, hold down the 'C' key and reboot.
You'll have to reinstall the OS (it'll probably note that a newer version exists, and ask you if you want to overwrite it. Say 'yes'), then after installation is finished immediately do Software Update to get the system up to 10.6.8. This can be lengthy if you do it through the 'Software Update' utility. A shortcut is to download the 'combo' update here:
http://support.apple.com/kb/dl1399
Just to be clear: you have to reinstall from the DVD BEFORE you try and download and run that combo update.
Once that's done, you should be good.
As a piece of general advice, never trash a system file and THEN try to update. You update with the file in place. Normally, just hitting 'software update' will do it. If you have a specific file that you think needs replacing, acquire the file first, then move it into place before rebooting.
Finally, never do anything like you did if you haven't got a backup. Use Carbon Copy Cloner to keep a regular clone of your entire internal HD. It would have taken you 5 minutes to boot into a clone and get the file off it that you trashed and saved you a whole load of headache!

2011 MBP 17" won't boot Hardware Test

My MacBook Pro is acting strangely lately. When I close the lid, sometimes it doesn't go to sleep. Also, when I shut it down via the menu system, it will go to a blue screen and just hang there for 30-60 seconds before shutting off. Sometimes it just goes to that blue screen while doing random tasks.
Almost every time I'm hooked up via Thunderbolt->HDMI, when I unplug the cable (disconnect from TV), the computer goes to a blue screen.
I'm trying to run the Hardware Test, but right when that OS9 menu comes up, the computer shuts down instantly. I've tried holding F2 while booting as well as holding 'D' while booting (with USB OSX 10.6.7 Install DVD inserted). No dice with either one.
I'm running 10.6.8 with 16GB of SuperTalent RAM. I have a 120GB Intel 320 SSD in the optical bay and the stock 750GB  HDD in the stock position.
Is my laptop now a dud that needs replacing?

Actually, I might have solved my problem. The last time I set this laptop up, I had directly copied my SSD to another HDD. When I put the SSD back in, I copied it back from Disk Utility on the boot up disk, again. That's right around when all of my problems started.
To solve it, I did a Time Machine backup, put in the install USB and formatted the drive (one-pass zeroed-out, to be exact), and re-installed 10.6.7. I updated it to 10.6.8, then used migration assistant to pull my documents/apps back onto the drive.
Since then, everything has been working very well. The screen has only turned blue once (in about a month), and it was only briefly. I haven't tried to run a hardware test from the install USB, but I'll do that soon to see if it works now.
I also took it into an Apple Certified Technician store before fixing the SSD issue, and they could find nothing with the hardware test they ran on it.
TL;DR = do a fresh install and then bring your files back.

15" MacBook Pro C2D won't boot

Hey folks,
I'm in dire straights here. My MBP C2D won't boot. In fact, it won't do anything. The only light that does come on is the charger cable, I get a green light there. Beyong that, absolutely nothing. Except for crickets.
I tried just pressing the power switch and holding down the power switch for about 10 second. Neither results in any activity at all.
Please help!

Take it in for service.

MacBook won't boot pt. 2

No more suggestions for a sick MacBook? White 2006 won't boot. Is HD dead?

Well thanks for your help guys. I finally talked to Apple through customer services and they are sending me a box so I can send it to them for a repair. They said it must be the hardrive that is bad. When she asked me what the problem was I told her what it was doing and what all I had tried to fix it. She then laughed and said "well, that was half of our troubleshooting!"
Does anyone know what my computer will be like when I get it back? Will it have Mac OS X 10.4.8 (including firmware updates) already installed on it? Will everything be ready to go? I understand that it wont have my documents and music and what not but that wont be a big deal.
She said the box will get here in about 2 days and then it takes 7-10 days for them to do the repair. She said she has had customers get there computer back in like 5 days which is good cause I need it for school.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

MBP won't boot after update!

I've got a late 2006 model. I'm hoping my problem isn't related to a hardware failure. I left it on during the day, came home, the fan was running hard and it was really hot. Performance was slow, but everything worked.
it was asking me to restart for the latest update anyway and I'd been putting it off for a day or two, so I decided to restart and let it go through with that.
But now, it won't boot. It starts up with the grey screen, a bar starts filling at the bottom, gets maybe 1/10th of the way, blinks out then another bar appears, starts filling, gets a little further, then the machine shuts off. Exact same process every time I start it.
I'm not really familiar with what my options are here.

I've got about 300 GB of space, so that shouldn't be the issue.
No, that certainly isn't the issue! Just had to make sure.
If it's not a hardware issue which happened to coincide with the update, the update may be corrupted or not completed. If either is the case, and you have another Mac available, you can try downloading the update from Apple Support Downloads, booting the MBP into FireWire Target Disk Mode (if it will cooperate), and trying to install the update that way. I have not tried this method, so cannot say if it will work or not, but I would try it prior to the alternative, which is to reinstall the OS (or, better yet, clone a backup to the MBP).

MBP won't boot - "GRUB_" - tried installing ubuntu on an external drive

so i tried installing ubuntu netbook remix onto an external drive, and upon restarting my MBP won't boot to my internal HDD, once it displayed "GRUB_" with a blinking cursor, but is otherwise unresponsive.
now i just get the folder with the ? on it.
I've run disk util, repair permission, repair disk and still no luck.
i can boot the MBP into target disk mode and see the HDD on my other system and all appears to be good, and if i boot to the install dvd, the HDD shows up under the "startup disk" menu, but it just doesn't boot.
any thoughts on how to fix this?

So I have an imac that I have had for about 3yrs. About several months ago, it started acting a little strange, it wouldnt pick up the mouse or the keyboard at times even thought they were plugged in properly to the usb port, sometimes both would work sometimes one or the other would work and other times they worked fine. About a month or 2 ago, I went to turn my imac on and it got to the screen where the little circular icon pops up implying it is loading, stayed that way for 2-3min then turned of and turned itself back on and did the same thing, made the apple sound got to the load screen turned of after 2-3min then turned back on, it has been doing that for the past month. What do I do?

MBP 2006 won't boot?
