IMac won't boot anymore after power cut

Thanks to the great storms in New Jersey, my iMac does not boot anymore after a power cut. Does not get past the apple logo screen with the spinning wheel and keeps rebooting every 2 minutes.
I was able to mount the HD via Firewire on a host machine and the disk seemed fine.
I booted from the Install disk and ran Disk Utility - seemed fine though I could not verify the disk permissions ?
One other thing - I seemed to remember the white light (front bottom right) was blinking before during start-up. Now it goes and stays black after couple of seconds.
Help please,
Philippe

HI Phillipe and Welcome to Apple Discussions...
If you haven't done so, try running the Apple Hardware Test.
http://support.apple.com/kb/HT1509
I doubt repairing disk permissions can't help this problem. It sounds like a hardware issue.
*"I booted from the Install disk and ran Disk Utility - seemed fine though I could not verify the disk permissions ?"*
When you ran Disk Utility via Firewire, did you actually Verify the hard disk for errors?

My iMac won't boot anymore

I've been using a 27" iMac since Octobre 2011 with a Lion/Windows 7 dual boot. It's always worked great, until yesterday: I couldn't boot into Windows 7 anymore, it wouldn't move past the drive selection screen that you get when you hold Option during startup. Lion worked fine, though, so I made an image of the Boot Camp drive, reformatted the partition and put the image back. This did not seem to solve it, so I decided to try a fresh Windows install. I let the Boot Camp-helper app create a disk with the needed drivers and partition the hard disk drive, but when rebooting I got stuck on a grey screen again. I managed to get the Windows 7 install disk out again by holding the mouse button at start-up, but now I can't boot into either Windows 7 or Lion. And to add another layer of tragedy: my Time Machine drive died last week and my replacement is still in the mail, so I have no recent TM backup.
What can I try to fix this?

Sorry if I sounded snippy, I'm just really getting tired of this, and I don't want to send it into the store yet because then I can't work anymore.
Superdrive seems to work fine, according to the handful of other discs that I tried. I'm going to check if I can make a copy of my Win7 disc, just in case it's something with the disc itself (but that still wouldn't explain why I can't get past the grey boot screen).
Oh, and I tried manually selecting the install disc but nothing, it just freezes up again.

Help! Imac won't boot anymore.

Hello. I am in DESPERATE need of your help. I have mac os x leopard and yesterday i update it, but the power went out in the middle of the update. now when i start it it just shows the apple icon and the small rotating wheel.
When i boot up in the Verbose mode, it just goes "Server: mdsync launch failed: (ipc/send) invalid destination port" and then 3 or saved crashreports with the loginwindow and a bunch of nubrs.
Its stuck in this loop and it just goes on and on.
I tried booting up with the cd it came with, but no help, disk utility AND fsck said its ok, in safe mode it dose not want to boot, it just stays in that grey apple rotating wheel screen.
I tried instaling it again, but with the UPGRADE feature, because i have lots of data on the machintosh HD main drive in some folders, and not in a user folder or such, so i can't use the archive and install, because i will lose all data.
Please help!
Thank you,
Sebastian

You can use Archive & Install. This moves the System folder to a new folder called Previous Systems and installs a new one. Other folders that exist on the drive won't be affected. Nothing is deleted in an A&I, only moved.
As a matter of tidiness, it isn't a good idea to have folders sitting loose in the root of the drive. You are much better off having them in a User folder; either your own or the Shared one.
I recommend an Archive & Install, as you have undoubtedly corrupted your OS when the power went out. You may have to reinstall some apps, but your Mac will boot.

IMac is not booting - How can I copy my files to an external drive

Hello,
my iMac (late 2009 model, OS X 10.7.4) is not booting anymore. The iMac stopps booting at the Apple logo and the spinning gear.
I tried a couple of things that I found here in the community but nothing worked.
start in safe mode => iMac shuts off after a couple of seconds
start with safe boot (Shift-Command-V) => I'll get a couple of error messages, e.g. disk0s2: I/O error. SATA WARNING: Enable Drive PHY PM failed
reset the NVRAM/PRAM => no change
But when I try to get access on the HD with the FireWire Target Disk Mode, I can see the following folders: Applications, Library, System, Users. But the statusbar shows 0 items for each folder and it shows that the HD has 650 GB available. I have the original 1TB HD. When I try to start OS X from an external drive I can see the same folders. I tried Data Rescue 3 to scan my files, but the software stopps with an error.
My TimeMachine backup was not working, so I have no actual backup and need to find a solution to copy my files to an external drive.
Instead of Data Rescue 3, I can use TechTools Pro 6 alternatively.
Would Data Rescue 3 find files if I erase and create a new partition on the HD?
What I found out so far, it looks like a corrupted file system.
Have anyone an idea or a tip, how I can copy my files?
I would be more than happy if someone can help me.
Thank you very much for all answers in advance.

The internal drive is failing, or has failed. You may not be able to save the data.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) 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
2. 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
3. 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.

IMac won't boot up after latest update. Any suggestions?

I just updated my software (the latest from apple), then my iMac won't boot again.

There you go. Your HDD is failing hence its not booting. You need reformat the HDD
To reformat, same steps: Boot to the install disc > get past the language selection > You will see Welcome to Blah Blah Blah > just hit continue > There should be something there called erase and install
BUT
1. if you are absolutely sure that Time machine has BACKED-UP all of your files then proceed above
2. If not, if you have another mac: connect it via firewire then google Target Disk mode. Basically you want to copy all your files from the damaged machine to the new mac to serve as a backup
3. if yo dont have another mac: get an external HDD, install Mac os X on it, boot to it then back up your files
to do this
a) Plug external HDD
b) Boot to the CD restart and hold C
c) Get past language selection and keep hitting continue
d) when it asks you where you want to install Mac os X > select the external HDD
e) once its installed. Restart the computer and hold "Option" key. You should now see your external HDD as one of the boot drives. Select that and you'll boot into it
f) once inside the external HDD OS, you will see the internal HDD(damaged drive)browse/navigate through it and start getting your important files

Won't boot anymore after nvidia-xconfig

Hey Guys,
Got a problem with my Arch Linux here, hope you can help.
Today I tried to install the official Nvidia Driver and BumbleBee following along the great Wiki on this topic.
Everything worked just fine and I also could run optirun gfxgear or somemthing like this.
I wanted to switch to the Nvidia Settings in the settings menu and it told me to configure my xconfig and restart x so I typed nvidia-xconfig in the terminal and it gave me an success output.
I restarted my system and now it hangs on the graphical thing I think. It won't boot anymore.
Hope you can help me out.
Thanks alot
Edit: My Nvidia Card is a Nvidia GT 740M if this matters
Last edited by Whitz (2015-02-09 11:02:41)

No, I have a laptop with 2 graphic cards an intel hd4000 and a nvidia gt 740m.
I ran the Arch Linux installation well until I tried to get the nvidia gt working with bumblebee.
I followed the wiki of the bumblebee topic and it worked well. I wanted to switch into the nvidia settings and it told me my x isnt configured properly and I should type nvidia-xconfig and restart X.
After the restart it won't boot to the graphical interface anymore.
Hope this cleared up the things
Also I dont get any errors but it just wont load..

Windows 7 does not boot anymore

Hi,
I have windows 7 operating system installed in my notebook. But suddenly my notebook is not booting anymore. I do have a backup image saved in a external hard drive, but can not install windows from there.
How can I re install windows 7 as I do not have a backup DVD.
Can anyone help me out?

Hay Munir
And how you have installed Win7 for the first time?
Jeka is absolutely right. You cannot start OS installation from image saved on external HDD.
I dont know which notebook model do you have but for Win7 installation you can use Microsoft installation disc. If your notebook model is supported for Win7 all necessary drivers, tools and utilities you can find on Toshiba support page. Just follow the link given by Jeka.

IBook doesnt boot anymore

Servus alltogether,
I really have a BIG problem with my iBook here. I've installed the Screen Spanning Doctor in order to activate a second screen, and my iBook doesnt boot anymore. It gets to the point with the grey apple and the wheel, and then (using apple+v) there seems to be a problem by loading a file called dyld
dyld:library not loaded: usr/lib/libz.1.dylb
etc/rx line 262 55 trace / BPT trap couldnt find root user usr/sbin /update
I tried to reset nvram in open firmware without any sucess. I can log on in single user mode, but i dont know what i can do now from there.
It would be also very helpfun if soneone could tell me how to mount a external hard drive (I have a Lacie hard drive, perhaps I can rescue my data. Its still there, I checked it in single user mode.) or a usb-stick.
Perhaps it is also helpful when I tell you this: It is a G4 ibook, using the newest patch of mac os x tiger, and my graphic chip is a ati readon 9200 (which should work with the screen spanning doctor but apparently didnt).
I am really in trouble here, because I need this iBook for university. So please help me if you can.

Try starting up from a CD (Apple-C) or in safe mode: http://docs.info.apple.com/article.html?artnum=107393
Either of these methods should get your booted. Then, back up your data! Next, try Disk Utility to fix your disk. You may have to reinstall the OS. Luckily, you have that backup now.

Lenovo 3000 N200 0769 A42 not booting anymore

Hi,
We have a Lenovo 3000 N200 0769 A42 that is not booting anymore. Concretely, when the on/off button is pressed, the fan goes on for a few seconds, the HD led is switched on and the CDrom is running for a few second too, then nothing else, except the "On" led that remains switched on...
I tried this: http://forums.lenovo.com/t5/Lenovo-3000-and-Value-line/Help-How-to-reset-CMOS-on-3000-N200-model-076... to no avail.
I removed the keyboard and unplugged for one minute the only plug I found with red and black wires, to no avail either...
The computer seems dead... Any suggestion to reanimate it?
Thanks in advance,
Pierre

Hi, Thank for the reply.
There is nothing displayed on the screen and no access to the Bios.
I did tried to reset the motherboard after having removed the AC power, the battery, the HD and the RAM (by short cutting two exposed metal traces labelled CLRP1 and by unplugging the battery cable found behind the keyboard. To no avail...

After upgrading to Firexfox 35.0 all vine videos, instagram videos and some webplayer videos dont work anymore.

After upgrading to Firexfox 35.0 all vine videos, instagram videos and some webplayer videos dont work anymore.
I get messages like:
ERROR 1
-Error Loading Media: File Could Not Be Found
http://i.imgur.com/5OaxOFC.jpg
ERROR 2
-Video can't be played because file is corrupt.
http://i.imgur.com/cqRpJOp.jpg
Before I start, I will like to point out some things Ive tried already so this doesnt end up being a back and forth of things already tried.
*Ive uninstalled adobe flash player
*Ive tried the whole
media.windows-media-foundation.enabled to false or to true
*Ive gone into safe mode and nothing
*Ive tried toggling off the plug-ins to see if anything I have problems with works. Nothing.
All the media that plays from different various players:
https://www.youtube.com/watch?v=v7IXmV6A6Bk
http://bestanimes.tv/mushishi-zoku-shou-2nd-season-episode-10/
http://www.watchcartoononline.com/mushishi-episode-26-english-dubbed <-- 2 embedded videos that both play.
All the media that wont play:
http://www.jwplayer.com/ <---- that front page video : I get ERROR 1 for this
http://videomega.tv/?ref=AJWOLaJQKbbKQJaLOWJA <--- I get ERROR 1 for this
And every vine and instagram video. Since I will be asked to post something from it here is something from vine and something from instagram
https://vine.co/v/OqxKQBJd3lm <---- I get a still image
http://instagram.com/p/up3CG6ooDP <----- I get error 2 if I go into page info and click the media tab and look for the video.
All my enabled plugins:
http://i.imgur.com/9fCZ1s2.jpg
Everything on my permissions even on the pages of the media I cant play is set to : Use Default.
Now, I thought this was just some kind plug-in problem, I even thought it was just something with the updated made Firefox incompatible with some of the webplayers. Of course I found out this was wrong. Keep on reading:
If your flash plugin crashes or if you terminate/end process in the Task manager, your video will be replaced by this grey message:
http://i.imgur.com/vudnNIM.jpg
https://www.youtube.com/watch?v=v7IXmV6A6Bk
http://bestanimes.tv/mushishi-zoku-shou-2nd-season-episode-10/
http://www.watchcartoononline.com/mushishi-episode-26-english-dubbed
http://www.jwplayer.com/
http://videomega.tv/?ref=AJWOLaJQKbbKQJaLOWJA
Now, all these videos I listed before, If I had them all open in tabs and then proceeded to terminate my flash plugin in Task Manager, they would all be replaced by that grey message window that the plugin crashed.
Now, after I updated firefox to 35.0, if I did the same thing
https://www.youtube.com/watch?v=v7IXmV6A6Bk
http://bestanimes.tv/mushishi-zoku-shou-2nd-season-episode-10/
http://www.watchcartoononline.com/mushishi-episode-26-english-dubbed
These three would show that grey message and these are the ones I can play
But these 2 the ones I have a problem with.
http://www.jwplayer.com/
http://videomega.tv/?ref=AJWOLaJQKbbKQJaLOWJA
they wont even be affected by it. Its like they arent even using the flash plugin.
Whenever I would terminate/end process my plugin from my task manager in 34.0 EVERYTHING, EVERYTHING would not work including every vine video and instgram video, it would either show that grey message that says the plugin crashed or it would not work. They would all work again when I refreshed the page. Everything, in 34.0 in my firefox was using the flash plugin.
Now, as I stated above I thought it was just some kind of webplayer and firefox 35.0 conflict that was causing these problems.
Until I saw this:
http://www.watchcartoononline.com/mushishi-episode-26-english-dubbed
http://i.imgur.com/gCaUMXm.jpg
http://i.imgur.com/V9w7ulS.jpg
http://www.jwplayer.com/
http://i.imgur.com/dqZtoTX.jpg
They are both using the same exact webplayer. THE SAME ONE.
I can play the first one
but the video in the front page of http://www.jwplayer.com/ I cant play it.
Which brings me to my final conclusion.
The reason I cant play some that fron page video of http://www.jwplayer.com/
videos from videomega.tv
and instagrams and vines
IS because of their file extension, their file types.
I went to the firefox options and clicked the Applications tab:
http://i.imgur.com/uWWKelX.jpg
http://i.imgur.com/HYBjwdZ.jpg
http://i.imgur.com/IK4C2WR.jpg
Shouldnt all those video file types be in : Use Shockwave Flash (in Firfox) instead of : Always ask
When I try to toggle it to something else I dont even get the option to use Shockwave Flash
http://i.imgur.com/gTH18S1.jpg
In Conclusion, what gives??
-In 34.0 Everything worked.
-If I terminated/ended process the Flash plugin in 34.0 everything would be affected by it , either by not working anymore or showing me that grey crash message.
-This all started when I upgraded to 35.0
-Has nothing to do with webplayer conflicting with 35.0 as proven above.
-The reason for all of this not working is the type of video extension they have. Judging from the examples I gave of the things I cant play, it would seem I cant play mp4, flv and whatever vine uses. Which I think its mp4 as well.
Anyways, how do I fix all this so it works like it did before I upgraded to 35.0

I looked at that but it only shows for Windows 8.1 , 8.0 , 7 , i have Vista , 64 bit Ultimate , would the Windows 7 one work ?? , or am i out of luck ?
And what plug-in icon in the address bar ?? , i don't see anything that pertains to any plug-ins
This is a example of one of the videos i was trying to watch , basically when you click the arrow in the center , it just goes away for a second then comes back and the video never plays , it just sits there , in the lower left corner i see a small popup that says javascript;

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,
Casey Burns

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !
