Odd: iMac Chime repeating after rebooting in Bootcamp

So If I just restart the computer normally while in OSX, nothing odd happens, One chime, Boots quickly into OSX. If I boot from OSX into Bootcamp, Same - One Chime, boots up quickly.
However, if I boot FROM Windows into OSX the Chime usually repeats 5-8 times before booting into OSX. Just last night however, Instead of repeating a couple times, The chime repeated continuously until I turned the computer off a couple minutes later. When I turned the computer back on, nothing happened, the keyboard and mouse did not work and no chime was sounded. I let it run for a while and nothing happened so I shut the computer down for the night. In the morning, the computer booted up with one chime and normally... Any idea wth is going on?

HI and Welcome to Apple Discussions...
Boot from your Mac install disc, run Disk Utility to see if there are errors on the startup disk.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*

20" imac won't restart after rebooting under bootcamp running Windows XP. I get a black DOS screen with an error message.

My imac has been running without problems under OS X Snow Leopard and bootcamp running Windows XP for a long time. I had received a Sony MP3 player and wanted to install the software on my computer. At the time I had a CD in my drive slot because I was getting ready to install some brother's software for a printer I wanted to use. I restarted my imac under bootcamp and started installing the Sony software in Windows XP. I was having problems with the install and decided to restart XP to see if that would help. It's been several days since this originally happened so I'm not of sure of any more specifics at this point other than I've had to use windows machines for a long time and know that basically when in doubt "restart".
When my imac was restarting I heard everything spinning up, the white light came on, but I heard no chime, a blue screen came up for about 15 to 30 sec. and then it went to a black screen with DOS characters giving the following message:
Windows could not start because the following file is missing or corrupt: <Windows root>\system32\hal.dll. Please re-install a copy of the above file.
I do have a copy of Windows XP, but my first problem was that I still had a CD in the slot and it would not eject. I tried every keyboard combination I could find including: eject button, F12 and holding down the mouse button at start-up and nothing worked. I also tried every other start-up keyboard combination I could find at Apple Support jut to see if I could get my imac to start up under OS X . I finally went on youtube to find out how to remove the CD. I ended up opening up my imac and taking off the cover of the CD drive to remove the disk. After putting everything back together I put in my Windows CD and tried restarting again. The exact same thing happened and I ended up at the DOS screen. Then I thought maybe my keyboard wasn't working so I replaced it with a new one. Same result. I also thought to plug both of my apple keyboards into my windows 8 laptop (hate it!) to see if they worked there at all. They both did so I'm sure the keyboards are not the problem.
At this point, since I do now have a windows 8 laptop (hate it!) there is no remaining reason for me to keep a bootcamp partition on my hard drive. My question is where do I go from here? I have a current time machine back-up on an external hard drive and I have my install CD for OS X Snow Leopard. How do I get my imac back up and running? Thanks.

Can you OPTION boot? If so, then choose the OS X volume to boot back into OS X. From there you can use Boot Camp Assistant to remove the Windows volume and restore the drive.
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
      "OPTION" key.
3. Release the key when the boot manager appears.
4. Select the desired disk icon from which you want to boot.
5. Click on the arrow button below the icon.
Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

MacBook Pro won't sleep in OS X after reboot from Windows

I have Windows 7 Ultimate 64 bit running on a BootCamp partition on my MacBook Pro running OS X 10.6.3. When I first installed 7 last year, I initially had a strange problem in that the Mac wouldn't sleep (default settings) when rebooted back into OS X from BootCamp. If I did another restart in OS X, everything returned to normal. I never found a solution to the problem but after a while it went away and things worked properly. Now, after several months and for no good reason I can think of, the problem has returned. Everything works correctly in both OSs except for this. Any help would be appreciated.

Tried repairing BootCamp in 7, no change, don't think there was anything wrong with it in the first place.
Here is a section of the log after reboot from BootCamp and it says "System Sleep prevented by active remote login session (600 second threshold)". This ONLY happens after a reboot from Bootcamp, after another reboot all goes back to normal. What could the "active remote login session" be?

MacBook Pro won't sleep in OS X after reboot from Windows (again!)

This problem originally occurred about a year ago and no solution was found then but after a time, it simply went away. Well, now it's back: after a reboot into OS X (10.6.7) from Windows (7 Ultimate 64 Bit), my MacBook Pro refuses to sleep until rebooted a second time, after which it behaves correctly again. The Console log reports the following message: "System Sleep prevented by active remote login session (600 second threshold)". I've disabled Growl and DropBox (possible suspects last time) to no effect, reset the SMC and PRAM, all the usual things. I've tried when connected to mains power or battery, on wired, wireless or no network at all and still the same problem. Sleep behaviour under Windows is correct. Hopefully the problem will eventually cure itself as it did last time but I would like to discover the reason and find out what this "remote login session" could possibly be. To reiterate, this ONLY occurs immediately after rebooting from Windows.

Whilst connected to internet itunes will only open once after rebooting and thereafter it will not open again until reboot. When reboot with internet off itunes will open repeatedly. Help

This problem has only appeared in the past few days before that I had nio problems with itunes. Firstly I discovered that I could only open Itunes once after reboot - thereafter it would not reopen until I reboot again. I have spent considerable hours yesterday talking to the Apple help by phone and tried all there suggestions including of course reinstalling itunes amongst other things. Eventually I thought the problem had been solved when I discovered that I could suddenly open Itunes repeatedly without rebooting. After a short time I then discovered that the reason it was working agai was that I had rebooted with the internet disconnected and itunes would open repeatedly as normal provide I left the internet disconnected. When I reconnect to internet the problem resurfaces. HELP

After reboot, iMac will not connect to wi-fi automatically

I very recently purchased iMac 27" with Intel i5. The issue is the wi-fi disconnects after rebooting the cpu. It doesn't connect automatically to the internet. It sees the router but I have to select it to connect. Although there is no need for me to re-enter the SSID password, it is a small inconvenience but I do not have to do this step for my other devices, like iPad, PC, etc. The wi-fi is there after waking up from "sleep" mode, so no issue here. I am currently using the OS X Lion. I also purchased the Mountain Lion but balked to install it yet because I read some reviews about it that it slows down some MacBooks (with retina). Could Mountain Lion have solved this wi-fi issue? Or should I take the iMac back to the store and let them fix it for me?

ML has caused more of this problem I believe.

File sharing between Mac Mini and iMac "breaks" after reboot of either device, and won't restore. Why? Running Maverick 10.9.1 on both. File sharing is setup on both. Help.

I'm a new user - recent convert from longtime Windows to Apple. Thought having desktops and computing aligned with phones and tablets would help. Not so far.
I have a MacMini running Mavericks 10.9.1, and an iMac running Mavericks 10.9.1. File Sharing is set up on both. If either device is rebooted for any reason, file sharing from the Mac Mini to the iMac "breaks" and will not easily restart. Various things eventually brings the connection back - usually having to do with checking and unchecking File Sharing, the AFP button, and/or the SMB button on the iMac - but never the same procedure twice in a row. File Sharing from the iMac to the Mac Mini is never disrupted - always comes back up without a problem. Screen Sharing also works between both without fail, and comes up after reboot of either. No problem there. Only difficulty is from Mac Mini to the iMac.
Why? Any ideas?

Should also clarify - usually takes multiple hours of checking/unchecking file sharing settings in order to restore the share between Mac Mini and iMac. NEVER happens automatically.
This is disruptive because I've got the Mac Mini pointing to several file locations on the iMac for various things - photos, music, etc. - and they all hang up unless the share is restored. Real bummer.

Hang after reboot ( Bootcamp Assistant )

I have a mac, which I want to install Windows to.
After running the bootcamp assistant, my mac reboots, and then hangs.
If I reboot again, into the startup menu, I see two DVD disk's. One called Windows and one called EFI something. If I choose the EFI something, I get into the windows installer, but it will not let me install to the bootcamp partition. If complains about a mix of partition types. If I choose the Windows disk, I am told there is not bootable device.
If I remove ALL partitions form the harddrive, using the windows diskpart utility, then I can install windows. But that is no great help, since I also want OSX.
I am running 10.8.2, and have triede both Windows 7 and Windows 8.

The EFI option is the wrong option to choose, you need to choose the Windows option. But because you used diskpart on the disk, which doesn't understand hybrid MBRs, you no longer have the proper hybrid MBR. That's what Boot Camp Assistant creates, and any other tool on the planet has a high chance of damaging.
So you need to use Disk Utility to create a single new partition, meaning go to the Partition tab, click "1 partition" instead of the default "Current" option. Install OS X. And then follow the Boot Camp guide step by step.

Re: Can't reboot -- chimes repeat over and over.

Internal Optical Drive not recognized after trying to Bootcamp

Around 3 months ago I tried boot camping my Macbook with Windows 7 but it ended up freezing and I had to restart my computer. When the computer had fully restarted I found that a few things had changed. First, I now had a 70 GB partition called BOOTCAMP but it was basically unusable since the Windows 7 OS was never installed in the partition, and second the Optical Drive wasn't recognized by my computer anymore so it won't work at all and the Windows 7 CD is now stuck in there.
I tried a lot of different ways that I found on the internet to try to eject the CD but nothing has worked. It's not really a huge deal since CDs are starting to become the new floppy disks but it would still be nice to have this working again.
Also, here's the original post that I made back in December. It never got any replies and somehow got moved but I was never able to see where it got moved because whenever I clicked "discussion" in "Branched to a new discussion." I would get a page that said this - "Unauthorized. Access to this place or content is restricted. If you think this is a mistake, please contact your administrator or the person who directed you here." I know the whole post is pretty long so I have a TLDR; at the end of it and I pretty much summarized the problem again at the top of this whole post.
Alright so earlier today I decided to Bootcamp my Macbook and install Windows 7 with a 70GB partition. I was using https://help.apple.com/bootcamp/mac/5.0/help/#/bcmp173b3bf2 and http://www.howtogeek.com/186907/how-to-install-windows-on-a-mac-with-boot-camp/ to help guide me through the process. Everything was running smoothly at first...I had a 32GB memory stick that I used to load the support software onto and I had a Windows 7 Ultimate 64-bit DVD in my disk drive.
The first problem I ran into was when Bootcamp wanted to download the files onto the memory stick - it wanted me to format the stick. So I went into Disk Utility, clicked on it, went to erase, then formatted it to the same format it was (because it was already FAT) and then it all worked. After getting the support software onto the memory stick the next step was to partition my disk. After doing a TON of research I finally decided that 70GB would be enough for the OS, a game or two, Sony Vegas Pro, and a few small programs. So I dragged the thing to give the new partition 70 GB and pressed install.
Then, the next problem occurred - a message popped up saying "The USB drive connected to this Mac contains a bootable volume. In order to install Windows 7 from the DVD, the Boot Camp Assistant needs to disable this functionality. No information on the drive will be removed, do you want to continue?" I was hesitant at this point to do anything so I googled it and couldn't find much except this thread - Bootable volume on USB flash drive in boot camp. I decided to try it and press continue since according to the thread it would stop me if there was a problem. Once I did I THINK (I can't remember that it did for sure or not) it dismounted the memory stick, which I remember thinking was okay because I could just unplug it and plug it back in after Windows 7 was installed to install the support software (Also, I NEVER removed the memory stick until after a reboot later on). After that Bootcamp began partitioning my hard drive.
About an hour later the blue progress bar had actually filled up to at least 99% (but it looked like 100% to me) but Bootcamp still said "Status: Partitioning Disk" so I left it alone for another 1-2 hours. After that I started getting worried and googled how long this process was supposed to take and found out that this step normally only took a few minutes for most people. At this point I started looking up fixes for this but nothing matched my problem since Bootcamp itself wasn't actually frozen (when I clicked and held on the icon it didn't say "Application not responding") so I decided to check to see if the partition had worked. Then, Disk Utility froze like a few seconds after opening it up so I had to force quit that. My next option was to check under "Storage" in "About this mac" so I tried that and it froze as well. While all this was going on I kept checking back to Bootcamp and it never froze.
Now I was getting extremely worried and with no solutions on Google and no idea what to do I decided to just try and restart my computer and pray to god that it would reboot fine. Luckily, it did...for the most part. After rebooting all my applications seemed to be working fine (I can confirm that Terminal, Disk Utility, System Preferences, System Information, and Safari are all working or at least loading). I also had all my files still on my computer so that was good. Next, I checked Disk Utility to see if the partition had actually worked and it did, or at least it is showing up as "BOOTCAMP" under my main hard drive. Then, I tried using Bootcamp again and this is when I noticed something new - a warning on Bootcamp's first page that wasn't there before, "You need an optical drive to install Windows. Connect an optical drive to your computer. You cannot install Windows with a remote optical drive." I can't guarantee that it wasn't there the first time but I really don't remember it there. After reading that I checked my Desktop for the mounted Windows 7 Ultimate 64-bit DVD and it wasn't there. Then, I checked Disk Utility and it wasn't showing up there either. The only things I can see on Disk Utility are my main hard drive with both partitions, my memory stick, and a random dmg file called decryptedFile.dmg (the size of this file is only 15.6mb so I don't think it could be the OS DVD).
So now I am trying to figure out how to get my computer to recognize that it does have an internal optical drive and that there is a DVD inside of it. I looked around on Google to try to find answers but all the regular options to fix this don't work since the computer itself is not realizing it's there. I don't know if this helps to prove that it doesn't realize this but I checked in System Information -> Hardware -> Disk Burning and it says "No disk burning device was found. If the device is external, make sure it's connected and turned on." And since a "Superdrive" can read disks I'm assuming it can burn them to and would be shown under that. (I don't know that much about computers though so I could easily be wrong)
Anyways, sorry for the extreme detail that I went into but I wanted to get as much information about what happened as I possibly could. For those of you who don't have time to read all that I'll put a little summary.
TLDR; Basically, I tried to Bootcamp my Macbook to run Windows 7 Ultimate 64-bit. I ran into a few problems and then Bootcamp wouldn't move on from "Status: Partitioning Disk" so I had to restart my computer. After the restart my Macbook doesn't recognize that it has an internal Superdrive and therefore doesn't realize that there's a Windows 7 Ultimate DVD disk in it. I looked around for answers but none of the simple ones (using key commands on the keyboard and typing something into terminal) worked. Now I'm looking for help to get my computer to realize that it does have a Superdrive inside so I can get the disk out.
Thanks in advanced! If any more information is required to help please let me know so I can find it. Also, this is a Mid-2010 White Unibody Macbook.

Hello Michael Dixon2,
Thanks for using Apple Support Communities.
In order to troubleshoot this issue where the optical drive does not accept discs, please follow the steps below.
Doesn't accept discs
Be sure to check your disc to make sure it is flat. You can check this by putting the disc upside-down on a flat surface. If the disc is bowed up on any side or in the center, do not use the disc because it might get stuck in the drive. Do not use discs that have anything attached to them or dangling from them (such as "sweeper" or cleaning discs).
If the drive struggles when you put in a disc or stops part-way, carefully look at the disc for labels that may be interfering. If there aren't any raised labels then try putting the disc in a few more times.
Try another disc to see if the issue is being caused by a specific disc.
Make sure you insert the disc far enough for the drive mechanism to activate. You need to insert discs nearly all the way before the drive will activate and pull them in. If you don't completely insert a disc, the drive will reverse and push the disc back out.
Allow the drive one or two seconds to accept the disc while it is fully inserted.
Reset the System Management Controller (SMC).
If the drive repeatedly does not accept discs, contact Apple or an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.

Ntpdate and ntpd not setting time when rebooting from BootCamp/Windows

I've got a farily consistent repro here, where my kids will reboot using BootCamp to play a game in Vista, and when they reboot back to Mac OS X, the time is set to UTC instead of adjusted for PDT.
I noticed in the system.log:
Oct 17 15:37:46 iMac ntpdate[114]: can't find host time.apple.com\n
Oct 17 15:37:46 iMac ntpdate[114]: no servers can be used, exiting

I've already tried the fix at http://docs.info.apple.com/article.html?artnum=303731 but it didn't seem to help;
I'm wondering if the network isn't fully operational yet (I'm connected 100BaseT to an always on cable modem, but hey, even that can take a couple of seconds) and that may be causing the issue...
Help is appreciated. Of course, I'm planning on switching to Leopard when I can, but for now this is just plain annoying.

That sort of showed me that the problem is that ntpd is running but it isn't connecting:
xxx $ /usr/bin/ntpq -c peers
No association ID's returned
xxx $
If I kill the ntpd's that are running and start them manually, I get:
ntpq> peers

time0.apple.com 17.72.133.55 2 u 10 68m 1 32.977 3.652 0.001
ntpq> q
Clearly I'm successful in connecting at least once, so how is this not working right after a boot when I've used BootCamp? If I just reboot the mac without having switched to BootCamp, I don't recall seeing this issue...
