IMac 20" Will no longer Boot.

I went to change the icons on my desk top this week and while playing around with them i miss clicked "Burn Macintosh HD to Disk" and it brought up bar as if it were copying something there was not Stop button and any way to cancel it and either way my dvd writer doesn't work so i just let it run it course after a few mins it stopped but i think noticed it had locked me out of all my external hard drives i went in and tried to change the permitions back to Read & Write but it would auto return it to "Custom" whenever i clicked off it, I went to restart my Mac thinking it would just reset it's self and now when i tried to boot it up it gets to the Apple screen with a spinning timer thing and it just stays there. Tried to re-boot it with the snow lepord OS Disk in and it still just sticks at the apple screen. Any one know how i can fix it or even get it to re install the OS?

If your DVD writer does not work, how are you booting from the Install DVD? Perhaps both the HDD and the ODD are shot. A repair/replacement of both may be in order.

After installing Leopard, my G4 will no longer boot in OS 9.22. (Classic still works, but I need it to boot in OS 9.) Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? What can I do to fix it?

After installing Leopard, my G4 will no longer boot in OS 9.22.
(Classic still works, but I need it to boot in OS 9.)
Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? (And what can I do to fix it?)
Details:
G4 Gigabit Ethernet
Boot ROM version: 4.2.8fl
Accelerator card added: 1.6 MHz
1.5 Gig Ram
I have erased the partition that had Leopard installed on it.
I zapped the pram.
In Open Firmware, I "reset-nvram", and then "reset-all"
I tried to reinstall G4 FW Update 4.2.8, but that must be done when booted from OS 9, and of course, that's the problem: it won't boot into 9.
I tried restarting from 9.2.1 DVD.
I tried restarting from an external firewire drive containing OS 9.2.2.
I tried moving a fresh OS 9.2.2 system folder into an empty partition on an internal hard drive. (Partition was created WITH OS 9 drivers installed.)
All attempts to boot into OS 9 give me the same results - grey screen - no spinning beach ball, no icons or logos - just a blank grey screen.
This machine still works fine in OS 10.3 and 10.4, and it worked fine for many years booting into OS 9, until I installed Leopard, and I haven't been able to boot into OS 9 since then, although I have done considerable research online and tried many things.
I have since learned that this machine does not support Leopard - 10.5. Fine, but how did it break 9.2.2?
Any help greatly appreciated.

Thanks for checking in, BDAQua.
Problem solved.
In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
"If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.

881W Will no longer boot with Radio Card installed

Hello!
I have a Cisco 881W that will no longer boot/operate properly if the internal radio card is installed.

Any chance this is a matter of a file getting deleted or corrupted or is this certainly bad hardware? The router sans Wifi appears fully functional.

You should be able to RMA the device. Search the forum for a post on the limited lifetime warranty:). They explain it good there.

When I upgraded to Mountain Lion on my iMac, it will no longer allow me to use selected folders from iPhoto to run as my screen saver. Is there anything I can do to fix that?

When I upgraded to Mountain Lion on my iMac, it will no longer allow me to use selected folders from iPhoto to run as my screen saver. Is there anything I can do to fix that? Thanks for your help.

Does this involve iPhoto i some way? Seems more like an issue with your web browser.

My iMac will no longer boot after half installing Maverick (only the essentials package was opened). How can I reboot it back to 10.8.5?

I was able to get a copy of OS X 10.9, but it wasn't the one straight from the App Store (which is free and I wish I knew before I got this other copy, but oh well). There is nothing wrong with the copy, it just simply doesn't initiate the install when you double click on it.
I installed one of the packages (essentials) off file, but not all the rest of them. For some reason the other packages weren't opening because it wasn't accepting my password, so I restarted the computer to see if that would make anything better.
It didn't. It now boots to the grey apple screen and stays stuck loading. I assume because only some of the install disk was installed, it doesn't really know what to do. But how do I fix this? How do I unistall the essentials package so that it goes back to normal?
I tried booting it whilst holding down "Command+Option+P+R" and it takes me to a limbo area where you can access disk utility. Within disk utility I can see that everything is still there.
What is the process to get it back to normal (I previously had 10.8.5).
Please help!

My iMac (late 2006) no longer boots from FireWire drives, although they contain all the system files.

My iMac (late 2006) no longer starts (boots) from Firewire drives, although they all contain a current system (Mac OS X 10.6.7). If the drives are connected with USB 2, they boot normally. The FireWire drives appear in the Start Volume program, but they do not boot. If I press and hold the Alt key while booting, only the internal drives and the USB drives appear as options. What can I do in order to boot from FireWire drives as I always could in the past?

I'd first recommend doing a SMC reset and if that doesn't work refer to:
http://reviews.cnet.com/8301-13727_7-10333969-263.html
and
http://www.thexlab.com/faqs/firewiretroubleshooting.html
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My iMac 2013 will no longer connect to my home wifi automatically why is that?

All of a sudden my 2013 imac will no longer automatically connect to my 2013 airport extreme base station every device in the house is fine ipads,ipods,epson 4 in 1,windows 7 PC & laptop etc.I literally have to turn the hopspot on my iphone to connect then for some odd reason this triggers the connection to the base station and from there its fine turn off the hotspot & all is well usually I just turn the mac on and thats it connection has never been an issue before.HELP PLEASE it should just work right!

There is a one year limited hardware warranty with all iPhones.
You can check your warranty by going to supportprofile.apple.com.
Try to restore the iphone as new without restoring from a backup. If that doesn't work, you're going to need a repair.
And if it's out of warranty, you will have to pay for it.

Made a new partition on Macintosh HD, Boot Camp will no longer boot.

Specs:
MacBook Air 2013
8GB RAM
i7
512GB SSD
Hello all, looking for some assistance.
My HD is formatted to 400GB of OSX and 80GB of Boot Camp. I stupidly made the mistake of adding a new partition out of the large amount of free space I have on the OSX partition, to format the new partition for Windows. This made Boot Camp no longer boot. On the Disk select screen after holding Option on boot, my Boot Camp partition is not visible. I can see everything on the partition on OSX, however.
To try and fix this, I deleted the new partition and tried to reduce the hard drive back to the original two partitions. However, I cannot extend the OSX partition to fill in the new free space. So now I have a Boot Camp partition, my OSX partition, and 20GB of unused, free space that I cannot use or put back into the original partition.
I asked AppleCare live chat for any assistance, they suggested that I use "Erase free space" in Disk Utility to use the space again. However, the option is greyed out on both the drive and the Macintosh HD partition.
After a bit of googling I saw a suggestion of making a USB Recovery drive to get the space back through Disk Utility that way. This still did not work; the results were the same, unable to add the space back to the original partition, and "Erase free space" is still greyed out.
Using BootChamp (notice the H, this is an app that allows you to restart and boot directly into Boot Camp through OSX), I get a DOS screen saying "No bootable device – insert boot disk and press any key". I cannot get this screen any other way.
I have repaired and verified the disk and its permissions, to no avail.
I cannot think of anything else to do short of formatting the entire drive but this is obviously less than preferable. I additionally do not have a backup of the BootCamp partition (as it is not accessible), even though everything is visible on the partition through OSX.
So, in summary, I added a new partition to my HD and now Boot Camp will not boot. Any ideas?

"rEFIt is an alternative bootloader for your Mac that's a lot more forgiving. If you don't think investing in iPartition is worth it, I'd give this a shot:
In rEFIt, do not boot: go to the EFI shell, and type "gptsync". This will tell you that the partition table is out of sync, and will offer to sync it for you. Say "yes", naturally. Now reboot and all systems should be go!"
This worked.

Bootcamp will no longer boot after deleting partition #3 of my new Mac Mini. What happened? Was it the way I tried to reclaim the HDD space for Mac?

Here's my dilemma. I have a new Mac Mini - a week old. I installed Windows 7 on it using Mac's Bootcamp assistant. I then set up and configured my Windows 7 world and everything worked fine. No issues logging in between Lion or Win7 via the restart/option key procedure. Well, yesterday I split my Mac HD partition one more time to create a third partition (was created as an "extra", e.g. possible future partition for another operating system). After creating it, I then decided that I didn't really need it. So I deleted it in Disk Utility and attempted to drag the Mac HD partition line downward so as to "fill in the gap" and reclaim the lost hardrive space. It seemed as if I could reclaim about 1 gig or so, but I figured...oh well.
Well, the Mac HD partition seems to work just fine, but now I've noticed that I can't get into the Bootcamp partition anymore. It wont boot. If I try to verify the partition [doesn't even give me "repair" as an option), then it fails and gives me the following error message: "verify volume failed. invalid request." When I go to the Startup Disk option in my System Preferences section, it displays the bootcamp partition as a folder and not as a drive anymore.
I'm assuming that I messed up some permissions or lost some vital links during my attempted resizing/reclaiming of harddrive space. How do I fix this without having to reload either all of my Mac info or all or my Win7 info? I'd hate to consider the last two days of my life loading this crap up a complete loss.
Thanks in advance!

IMac will no longer boot-up, Pink Lines

27" iMac running Mavericks, purchased March 2010, a great computer; that is until something goes wrong and local Apple support resources are scarce in my location!
Prior to the issue occurring I was performing a cut/paste from a website to a document and noticed red square dots on the screen behind the document I was working on, all functions were frozen. I did a cold reboot and this started normal then horizontal green lines appeared and the system would not come up. I turned the iMac off via the power button and after a couple of minutes switched on again this time the reboot worked, a error log and the option to report the fault to Apple was displayed, I typed a blurb about my issue and sent it off (I do not know what happens to them it felt good). There were no issues for the next few hours using standard functions like web browsing, Email and documentation etc.
While working on a Genealogy profile later in the day I again tried the 'cut and paste' process from a website to a document and the same issue occurred this time however there was no respite; each time I rebooted white screen, 5 horizontal pink lines about a cm wide the Apple Symbol and the wheel spinning then the pink square dots on a white background the dots were green over the apple symbol no other functions possible.
I would like if possible a diagnosis for this issue and if possible a ball park estimate of potential repair, recovery costs, I store most of my records, media etc on a external HD it would great to restore from a backup rather than start from scratch again!
I have photos of the screen images but cannot post on this forum

I can boot both Snow Leopard and Leopard install disks, no problem. I cannot boot ANY version of Windows install disk (XP, Vista, 7). My Super Duper backup was a backup of my Snow Leopard install to reformat the drive, since one theory was that the partition table was messed up. No go.

IMac will no longer boot ANY version of Windows CD/DVD

I have a 20" unibody iMac 8,1 that originally came with Leopard and has been upgraded to Snow Leopard (currently 10.6.1). During Leopard days, it had Boot Camp running Windows XP (for games) and worked fine. At some point, boot camp was removed and the system was returned to a single partition. Recently, I've decided to install Windows 7 Ultimate 32-bit (retail cd) and so went through the Boot Camp Assistant to create a new boot camp partition and launch the Windows installer DVD. After going through the partition process successfully, the Windows 7 DVD failed to boot, ending in a black screen with a flashing underscore ( _ ). I tried to boot the Windows 7 DVD several times with the same result. Thinking that somehow the Windows 7 DVD was damaged, I got out my Windows XP install CD and tried to boot that, with the same result (black screen blinking underscore _ ). I tried this with a retail copy of Vista Ultimate 32 bit, with the same result. I have run Disk Utility and verified the disk contains no errors. I have tried manually forcing the boot to the Windows install DVD/CD's by holding Alt during boot, and manually clicking on them, with the same result. I have backed up the entire HD with Super Duper and erased the disk and then restored the from Super Duper copy, in case there was a problem with the partition table. All with same result, blinking underscore on a black screen when attempting to boot off Windows install media.
This machine used to have boot camp successfully running XP under Leopard. Now I can't even boot from a Windows install CD/DVD (any kind of windows). What has happened? Did the Snow Leopard installation change something? Is there a firmware update that is needed? I have tried resetting PRAM and SMC with no result. I am out of ideas. All of these windows install disks work fine if I boot them with my MacBook Pro. It's just the iMac that won't boot a Windows install DVD/CD, of any kind.
Help!

IMAC will no longer boot into Windows 7 with Boot camp

I can see the partition on the Mac destop and can access it.
The windows options is available when I hold down the option key when booting but the computer appears to just hang.
I have been unable to get the Imac to boot off the Windows 7 dvd or a repair disk. I just get a white screen.
I could sure use some help trying to get the computer to boot back in Windows.
Thanks in advance.

Oddly enough I turned off the computer for a bit and turned it back on and it boot right into windows.......
I did have my Samsung phone plugged into the usb hub.....I wonder if that was causing some issues...weird.

Macbook pro will no longer boot from main sata bay after Yosemite

Hi!
I am really stuck as to why my macbook pro will no boot from the main Sata bay.
I have the macbook pro late 2011 - a few months ago I installed a samsung 840 evo, and moved the 500gb hdd into the optical bay and all has been working perfectly until last night.
I installed yosemite two days ago and it worked perfectly to begin with... then when I re opened my laptop everything was frozen. I restarted it and it wouldnt get past the grey screen. Then I managed to get it to the internet recovery stage....however it would not recognise the SSD, so I had to install Lion on the HDD.
After I logged on it gave me the message saying that the disc is not readable and on disk utility I can only see the "samsung ssd" but no details about it.
I thought that the SSD may have gone, but when i removed it and plugged it in via USB I was able to boot from it with no issues.
Does anyone know if this has anything to do with the new OS? or whether it is the Sata cable?
Thanks for any help!!!

Hi, I have been having the exact same problem with a late 2011 MBP 15 inch. I replaced the hard drive with a samsung SSD 1.5 years ago, along with a samsung SSD in the optical drive. It worked great until the Yosemite upgrade. The MBP seemed to work reasonably well for a few days after the upgrade, but then it started stalling on various programs (spinning beach ball on Mail, Safari, etc). Start-ups were also longer and had a loading bar each time, which was new since the upgrade. I left the MBP to sleep last night and when opening it, it crashed and tried to restart. On restart it loads to the login screen, then after I enter the password it partially loads (based on the loading bar), then shuts off. I removed the SSD and plugged it in with a USG, but that didn't change anything. Here is a picture after using CMD-V before it shuts off.

How do i retrieve file vault protected files from an external hard disk that used to be my mbp's hard drive? the hard disk got corrupted and will no longer boot. I put it in an enclosure and attempted to copy my files but failed because of FV encryption.

This external hard disk used to serve as the main drive of my mbp. It got corrupted and the OSX would no longer load. I upgraded to a 500gb hd and used the old hd as an external drive. I tried to copy my files but i could not access them because of the filevault encryption. 110gb of hd space appears as used which means that my files are still in the drive. Is there a way to retrieve these files? thanks

According to your post, you're using Leopard, so FileVault only encrypts your user folder (unlike Lion). On the mounted external drive, in your user folder, you should see a file called username.sparsebundle, with username being your user name. Double-click that file to open it and it should prompt you for a password. Type in your password and the file will mount as a volume in Finder. You should be able to copy all of your files over.

15" Macbook Pro (2007) will no longer boot in any manner. (Please, help.)

Evening, everyone.
I could beat my head against the wall for all the frustration my MBP is giving me! I really hope some kind soul will be able to help me. I will try to be methodical in explaining the whole story of what I have done and what appears to be wrong, so that maybe you fine detectives can pluck out the relevant information and piece a solution together:
I was multi-tasking about two days ago (perhaps too much) and I had installed the most recent OS X (Leopard) Auto-update. I had also downloaded and installed the program "Little Snitch," and both the update and Snitch were asking that I restart. So, I did--sure enough, it went to the spacey-purpley Leopard screen and appeared to have successfully updated. It shut off and began to boot up as usual. However, it appeared to be stuck at the Apple and rotating dial screen, with the bluish-greyish background. All of a sudden, the screen went black and the computer shut itself off completely.
I tried to turn it back on, with the exact same sequence of events. I ran it in Cmd-V mode (is it called.... verbose?) and it mentioned Little Snitch amidst the rest of the report (which is what makes me concerned that it might be the source of the issue). At the end of the repost, it said something about "shutting off the CPU" and "killing all processes." Then, again, it shut itself off completely. I tried Cmd boot up (to select the boot disk, as I have a Bootcamp partition with Windows XP that has never caused me trouble before) and selected the OS X volume. Again, no change.
Finally, I hunted down a friend who had just purchased a new Mac to borrow his OS X install disc. I upgraded to Tiger, so I don't know if that might be why his boot disk did not work for everything I needed it for. I don't have Y disc with me, because I'm from California and I left it somewhere in my office. But, I was able to boot from his disk--although it reported that I "could not install OS X Tiger on this machine"--and use the Disk Utility. I tried to use the verify and repair functions, but they both came back with "sibling errors."
I may have made a crucial error here: I then tinkered with the Open Firmware Password Settings. I tried a few of the things I already had over again, and then went to bed.
Well, that was all last night. I came back from work today, determined to try using target disk mode and my friend's mac in order to solve the problem. I followed all the procedures necessary, plugged in the cable, booted up my kaputnik target computer holding down the "t" key, but my computer was totally unresponsive to the command. Now, NONE of the start up commands will work. I cannot boot from the OS X disc, I cannot run the cmd-v thing, I cannot "Cmd" select a drive at startup... I don't know if this has to do with my setting of a firmware password, because it was not doing any of this stuff yesterday.
I'm freaking out. I'm a student, it's finals time, and I have 3/4 of my thesis on that machine. Please, help me work this one out. Even if it's just a way to get to the hard drive in target disk mode to get those files I need without really fixing the problem. I'll be happy to provide any other information that might be helpful in finding a solution.

Restart with the Option key held down and the Mac OS X install disk inserted, provide the firmware password, click on the DVD, press the button with the straight arrow, access the firmware settings, disable the password, and use FireWire Target Disk mode. If you can't do that or it doesn't work, contact Apple.
