Imac displays a black screen stating "No bootable device --insert boot disk and press any key", imac displays a black screen stating "No bootable device --insert boot disk and press any key"
I've had boot camp run a setup on my macbook pro, I have a disk from Dell that states "for reinstalling Dell Inspiron and XPS system software". I would not read the disk as I am still looking at the black screen that portrays the Above statement of "No bootable device --insert boot disk and press any key"
my keyboard is inoperable at this point until I could do anything further with the above directions. This was my first time using a Mac and Boot Camp was a setup that I thought would help me become more well aquainted due to my history with windows. Could anyone be of assistance w/ my situation?
... I have a disk from Dell that states "for reinstalling Dell Inspiron and XPS system software".
It sounds as if that disk is specifically meant to install the Dell's operating system for that specific computer. It is not a generic Windows installation disk. Microsoft has strict licensing requirements for Windows and I would be surprised if the Dell disk would be useful for anything other than the computer with which it was included.
You need to buy a copy of Windows that is not machine-specific.
I recommend you forget Windows unless you have a pressing need to use it. I can't think of any.

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.
Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.
Disk Warrior / TechTool Pro 5 / Drive Genius 3 - top 3 probably
There are always going to be normal items you just ignore with Repair Permissions. Useful to do once in a while but not magic. Same with SMC and the rest. Running disk repair is one of those things that it seems should be done before there is trouble, not after, and a weakness in HFS file system and disk directory.
Apple Support is a good place to start looking and then hardware category.
http://www.apple.com/support
http://www.apple.com/support/imac /macbookpro etc
Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?
You can overheat a hard drive with needlessly running 7 and 35-write pass, besides which the best way to map out bad blocks is not Disk Utility.

Howdy OatsaMae,
It sounds like your screen is flashing unexpectedly on you for some reason. I would recommend this section from the following article to help you get that resolved, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Take care,

I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well. However, itunes can not do anything with the phone because the phone is locked and I can not unlock the phone because the screen is black.
>CURVEBALL!!!<
The screen does work though! Through trial and error along side a little troubleshooting, I was able to figure out that the screen will cut on after the phone dies completely. The phone has to die completely with no battery power left. Then if I plug the phone into a charge and wait a while for it to charge, the phone will turn on like nothing was ever even wrong with it. I charge the phone up to like 30% and turn it off then bam the phone turns on but the screen is solid black again.
I am currently in the process of waiting for the phone to die and when I turn the phone back on I am going to completely remove the auto-lock and lock code off of the phone for the time being.
Any other suggestions? Please help!Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement. -

i need to connect my Imac 27'' (newest version) up to 3/4 monitors (all 40'' LCD tv's with VGA and HDMI connections) with extended display to all external screens, not duplicate images. Is this possible?
I would suggest you visit an Apple dealer, preferably an Apple Store if there's one in your city, and ask for assistance in determining what you need. The questions and issues you bring up are rather complex to address in a technical support forum and would be better addressed in person where you and the salesperson can ask questions back and forth to arrive at the optimal setup.

Desktop screen keeps flashing black and dock has disappeared. iMAC X Yosemite 10.10.1
Recently I updated my iMac to OS X Yosemite 10.10.1. All was operating smoothly for a few weeks until one day i started up and logged in my dock was nowhere to be seen. The desktop screen started flashing black replacing my desktop image. None of my desktop icons disappear when this happens. screen keeps flashing black every few seconds. Also the dock has disappeared.
I have restarted in safe boot and it makes no changes.
iMAC X Yosemite 10.10.1
Please help!Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if Safari crashed, you would enter "Safari" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful. -
my ipad froze during a upgrade. it might have run out of battery. i brought it with me to work and i'm charging it but it keeps displaying a black screen. it wont even let me power it off.
If it is totally black, all the time, and you can never see anything on the screen, I agree with stef7 - it needs replacing. Is it still under the manufacturer's warranty?
Is the proximity sensor (dot(s) on top of the phone) covered by a case or screen protector? That would make the phone "think" you are holding the phone at your ear to talk, and will turn off the screen to save battery.. -

Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this. -
Screen Flicker and Glitch on 24" iMac, Early 2009
For a while now, my iMac has been having somewhat random display glitches, flickers, freezes, and kernel panics that can only be fixed by shutting down the computer.
Most of these screen glitches go like this: The display flickers black quickly, letting me know that an issue is going to arise. The issues that could happen are as follows:
A blue line glitch (very common)
a random artifact glitch (somewhat uncommon)
a freeze-up (very common)
a kernel panic
Let me describe these:
There are several types of "display glitches" I've been experiencing. Some of them involve random artifacts that are randomly displayed and seem to be hovering over whatever is going on on the screen–for example, once I was browsing Facebook and the glitch occurred, so a square of my browser screen was sort of cut out and stuck on the screen above everything else going on. The issue wasn't fixed until I restarted the computer. This glitch, however, wouldn't show up in screenshots. These are somewhat less common because it seems if this one happens then it either gets worse very fast and there are random pieces of my active windows all over the screen or it freezes the computer up entirely, or even results in a kernel panic.
Another "display glitch" that is far more common is a sort of line glitch. It's very strange: blue lines will outline random shapes and things all over the screen. Pictures on my browser appear distorted and videos look VERY weird. The dock has the lines and random blue pixels as well. The desktop background appears distorted. This glitch often starts with the screen flickering black and the various blue lines appearing. The lines change shape as the objects on the screen move around.The issue doesn't appear in screenshots but I documented it by taking crude videos and pictures on my phone that give examples.
Here's a link to my video of a video about a nonrelated screen glitch. I was actually searching Google for a solution but it turned out to be unhelpful, but since the screen glitch happened to be going on I decided to record it as an example. Notice how the blue lines move with the video...
Here are some pictures:
This next screenshot looks a little creepy with the armored polar bear–it's a LoL build on Mobafire. CLICK HERE TO SEE WHAT IT'S SUPPOSED TO LOOK LIKE:
---NOTE: My computer actually JUST screen glitched and froze up completely, at which point I had to shut it down and reboot. Luckily the post was saved! Just in case you were wondering how often these things occur.
This issue is getting worse and worse. I'm not sure what triggers it, but it seems like graphics-intensive programs like 3D games can trigger it–especially, it seems, when I toggle on and off fullscreen. It looks like it could be a graphics card issue, because if it was a software problem it would seem like it should show up in the screenshots. It's sort of an underwhelming graphics card, but meh. My mom is having a panic attack and backing up everything on the computer and we're thinking about just reinstalling OS X altogether.
