IMac continuously restarts after bootcamp failure

Hi, I hope I'm posting this in the correct forum!
I've just done a fresh install of OS X Snow Leopard on my 2 and a half year old iMac. (I wanted a clean HDD before going back to Uni), I installed all my software and finished up by trying to install Windows 7 Home Premium via bootcamp. Bootcamp partitioned the HDD and restarted with my legitimate Windows 7 disk in the drive. But now it doesn't start back up! Just a white screen for 10 minutes or so then it restarts again.
The only way I can get onto my mac is by holding down the alt key as it tries booting up and it lets me select my Mac HDD. That's the only one it shows. I remember having the same problem at the start of the year, so a fresh install of Snow Leopard should fix it, I know. But I've just done this once and it took all day to sort of my programs! It'd be a hassle to have to go through it again, is there anything else I can do?
Thanks.
Edit: I originally set 60GB for Windows, after that failed I erased the partition and tried again with the default 32GB. None of these attempts worked and after erasing the windows partition a 2nd time, it still doesn't start up properly. (My iMac is a 20" intel model) Thanks again

Hi,
to avoid the neccessity for the useage of the Option-key got System Preferences in OSX - then Startup Volume and set your OSX to be the Default Startup Volume.
After that your Mac should start automatically in OSX on the next reboot.
Then you can/schould use the BootCamp Assistant again to revert the done partitioning back to one single OSX partition.
Refer to the BootCamp Installation Guide.

Stefan

My iMac wont restart after my last update alumni keyboard

Please help, I am using my MacBook for this, my iMac will not restart after installing the last update, alumni keyboard....., after restarting, pushing the start button, all i see for hours, is the apple logo with the little circle spinning under the logo, please help, i already, disconnected, unplugged everything, used my original keyboard and mouse instead of my bluetooth, but nothing works, even ,power on while pushing option button etc. Anyone else know of this problem.Thanks in advance!

The long tone is an indication that a firmware update is installing. Do you get a progress bar at the bottom of you screen after letting the power button go?
Have you reset the PRAM? (cmdalt+PR when you restart the machine)
Also repair permissions when the machine is up and running.

Satellite A200 continuously restarts after windows update

Hey all,
The model Satellite A200-1GB (PSAE6E) worked perfectly for two years now (with Vista 32bit).
Since running windows update yesterday and restarting, the laptop's been stuck in a loop of restarts, immediately restarting after the "POST" screen (Toshiba logo, etc) with a flash of blue screen.
Holding F8 to read the message, it says INACCESSIBLE_BOOT_DEVICE (0x000007B) ...
Trying to restore to a point before the failure failed for unknown reason (gave an error).
Research in Google yielded a possible cause - maybe harddrive driver has changed to an incompatible type. There were some suggestions to turn off AHCI support in bios, but it doesn't have that option.
The bios was not updated since purchase (it's version 1.4), but I can't update it because it seems the only update provided by Toshiba requires windows.
Anybody has any clue how to fix the computer without reinstalling windows? Anything?
Thanks in advance,
Ofir

Hi
I doubt it could be a hardware error (my personal opinion) but nothing is impossible you know
The point is that a BSOD can be caused by hardware error but also by an serious software issue
In my opinion something went wrong during the update
If you are not able to start the OS even using an safe mode then a new OS installation would be the last chance to get this issue sorted
I think you should try a new install in order to find out if this could be a hardware issue because there is a small rest of risk that this could be a hardware problem

Imac keeps restarting after upgrade to OS X

Just upgraded imac to OS X. After I log in it freezes and restarts after 20-30 seconds. I can start-up in safe mode, copied this error:
No other H/W upgrades...just the OS upgrade. I tried to reinstall OS X, still have the problem. Any ideas?
Thanks,
Craig

Uninstall the Trend Micro product by following the instructions on whichever of the pages linked below is applicable:
Removing Trend Micro Titanium Internet Security
Uninstalling Trend Micro Smart Surfing
Restart. If the program was incompletely removed, reinstall it and start over. Back up all data before making any changes.
If there's no improvement, remove "Elmedia Player."
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and (unless otherwise specified in this comment) I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

IMac shutting off after bootcamp/windows installation

I've succesfully installed a Bootcamp partition and Windows 7. This is the second time I've done this, and I'm noticing a trend. For some reason, the computer, when in OS X, will shut off by itself. I've never actually seen it do this, but it happened the last time Windows was installed. When I deleted the partition, the "phantom shutdown" stopped happening. I had thought it might be due to heat (it was summer, it was hot, I wasn't running AC) and when I deleted the partition it was getting cooler. But after the partition deletion, I never noticed a phantom shutdown again.
Then last weekend I re-intalled the partition and re-installed Windows 7. The computer, while in OS X, has shut down three times on its own. Again, it hasn't done this while someone was actually on the computer. So, it appears to be only doing this when in 'sleep' mode. The interesting thing is that I previoulsy had Snow Leopard when I had the partition before, but am now running Mavericks.
Has anyone else experienced this?

It cannot. Windows does not install nor boot from external or USB drives. You need to create a special USB booter on a USB flash drive. There are numerous methods for doing this which you can find doing a Google search. Unfortunately they all require a working Windows PC to do so.
Alternatively, you can try using VM software such as VirtualBox, Parallels, or VM Fusion - CNet Downloads or MacUpdate - to create a Windows VM on the computer. From there you can create a USB flash drive installer for Windows. You may even be able to install Windows from the DVD/CD from the VM, but I'm not sure if that will work since the disc will still be on an external drive even though the VM will access an external optical drive.

Problems restoring partition after bootcamp failure

Hi!
I'm using a new MacBook Pro (Retina, 15") with OS X 10.10.2 where I tried to install Windows 8.1 with the help of the Bootcamp-assistant. Everything went well to set up the partitions and I decided to set aside 50 GB for my Windows partition. But the Windows 8.1 installer for some reason refused to install on this partition so without thinking too much (big mistake) I tried formatting it from within the installer which didn't work and lead to boot problems when I restarted. Without knowing so much about these things I understand that the Windows partition manager where writing in places on the disk that wasn't so good for the OS X system? Anyway, I have managed to get back to booting normally and within the Disk Utility in OS X I deleted all the different small partitions (that I could see) and the 50 GB Windows partition so that there is now just the main OS X partition showing and 50 GB of unused, unpartitioned space.
An this is where I'm stuck. Everything works fine except I now have a 50 GB smaller disk... I wan't to restore everything back to having just one big OS X partition but I can't use the Bootcamp-assistant since it does not recognize the disk as being managed by it and from inside Disk Utility I can't resize the OS X partition back to normal. I can't pull the slider to increase its size, I can't manually type in the partitions size since those numbers are greyed out and I can't create a new 50 GB partition of any kind since when I try to proceed nothing happens. I have even attempted to format the whole drive and restore my time machine backup from recovery mode but I can't figure out how to do that. I seem to be able to format the, now smaller, OS X-partition but doesn't that just create a new partition with the same size? How do I erase everything and create a completely new partition with the maximum size? Oh, and I also tried removing the OS X-partiton by pressing the minus button at the bottom but that button is greyed out as well. Even in recovery mode...
I have included two screen dumps. Sorry for them being in Swedish... Hopefully they can be of help anyway.
Thank you in advance for any help!!

This problem is being discussed in Is there a way I can get the "Free Space" back without completely restoring my hard drive?

Restart after power failure: AICS 5 trying to open multiple files

I recently had a power failure while working in AICS5 on Mac OS 10.7.5. When I restarted, AI reopened and tried to open every file I've worked on, in the last month or so. Can someone tell me what is going on and how to stop this in the future?
Thanks.

Probably the preferences were corrupted either Illustrators or your user account.
First try this: (they way yiou find the Username/Library is to to go to the Go menu of the finder and while holding the option key down otherwise it is invisible)
1. Quit Illustrator.
2.Go to User/username/Library/Preferences/ Adobe illustrator CS5 Settings and trash the settings folder, the whole folder not just the contents of the folder..
3. Start Illustrator. Illustrator creates a new preferences file.
If that does not work create a new user account and log in if it does not happen and it won't and AI preferences prove not to be corrupt then you have a corrupt user account.
You will either need to delete the old user account or find out how to use the Terminal to kill the process causing the OS to tell Ai to open all the files you opened in the past under its current state.
You can also try to repair the permissions but I the the user account is corrupt.

Safari constantly resets default prefs on restart after bootcamp

Hello All,
This problem has been rearing its annoying head for quite a while!! Safari on Mac OS X runs fine.. It is only after running Windows/Bootcamp and rebooting into OS X that I find Safari has reset to default preferences and all my homepage/customized toolbar are gone!! This happens EVERY time I use Windows..
Any ideas..?

Imagine a puzzled person. That'll be me then
I think you and [KingRichard|http://discussions.apple.com/thread.jspa?threadID=1868672&tstart=5 0] should form a "BootCamp against Safari group"
Can you answer the last question in that thread as well (i.e. does the Safari preference file go missing completely after using XP, or has it magically restored to a default file)?

IPhone 3GS continuously restarting after iOS 6 update

Since I updated it, I've not been able to put it in recovery mode, get iTunes to recognise or turn it out. The apple logo appears for around 3-5s when turned on, but then restarts and repeats until the battery goes flat. Any fix to this or have I just totaled my phone because of this stupid ******* company?

Charge iPhone on Wall Charger for at least 20 minutes, longer will be better, but maybe 20 minutes will work. Then open iTunes on computer. Then connect iPhone to computer with USB Cable. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode, usually takes about 20 seconds of holding both buttons. Click the Restore button of iTunes. If this does not work last step would be to perform a DFU Mode Restore.

Imac wont boot after power failure.

I can boot in target mode and plug another mac in via firewire and run disk utility, but cannot boot the imac on its own. Anyone know what causes this? I have tried to boot holding down command-r, nothing, don't have install disks as they don't ship with them anymore.

Hello
Try boot in safe mode - Hold on at start-up SHIFT key , at least for one min , see if you ah safe mode start up
Try boot in single user mode - Hold on at start-up CMD-S , see if you have a comande line interface - type exit comande to try boot graphic interface
Try boot Apple Hardware Test - boot with D key
This 2 try need an valid Internet acces ( ethernet cable or wifi enable )
Try boot Recover mode - CMD - R
Try boot Apple Hardware Test - CMD - D

APC UPS (uninterruptible power supply) not restarting after power restored

I just bought an APC UPS 1500VA Smart-UPS (model SUA1500) to protect:
-- iMac 20" 2.16 GHz Intel Core 2 Duo with 2GB memory and 500GB internal disk
-- (2) external Seagate FreeAgent Pro 750GB USB drives
-- (1) external MacGurus Burly Firewire enclosure with (4) 1TB Seagate Barracuda 7200.11 drives
-- DSL modem
-- Ethernet hub
-- Airport Express (b/g-model, not the new n model)
The UPS is connected to my Mac via USB cable. The UPS shows up in System Profiler as "Smart-UPS 1500 FW:601.3.D USB FW:8.1". It also appears in System Preference Energy Saver pane.
I have configured the Energy Saver preferences pane to shut down the computer when 75% of the UPS battery remains. And to restart after power failure (both on power adapter and on UPS).
So I cut the power to the UPS and the computer properly shuts down when the battery reaches 75%. A couple of minutes later, the UPS turns itself off. All good so far.
PROBLEM 1: When utility power is restored, the UPS does not restart. APC's documentation says it should. Is the Mac sending some sort of shut-down command to the UPS over the USB cable that is preventing the USB from restarting?
PROBLEM 2: After I manually start the UPS (by turning it on after utility power is restored), the Mac ignores its setting to "automatically restart after power failure." I want the machine to restart itself because it is my backup server, music server, and provides file sharing access for other computers on my home-office network.
Anyone else having trouble getting their UPS or Mac to restart after a power failure? Any thoughts? Any configuration settings I'm not getting right?
Many thanks.

The "Restart automatically after a power failure" option only restarts if the computer was running when power failed. Since you had it shutdown before the power failed, it's not going to restart. Maybe Mac servers, or the server version of OSX, have more options.
Instead of shutting down when the UPS battery is almost dead, you could just stop all the applications that write to disk, so there won't be any disk operations in progress, then wait for the power to fail. It will then restart when the power come back. You should have something running to monitor the UPS, in case power returns, and the UPS doesn't shut off its output. In that case you should have it restart your applications.

OS 8.6 won't quit or restart after hard shutdown

While testing a G3 266MHz beige mini tower running OS 8.6, the system hung and refused to shut down even when the power button was pressed and held, so I literally had to pull the plug. The operation it hung on was opening a folder containing a large number of files (several thousand) on a mounted volume from an OS 10.4.8 machine. Disk utility and DiskWarrior reported no damage after restarting the machine, however the machine now seems to have a problem: it refuses to shut down or restart from "Special" menu and still refuses to turn off from the power button. I can change the startup disk to a utility volume and run repairs from it, which I just did even though no damage reported, but when booted from the original disk problem is still there. Any ideas as to what's causing this behavior?
Thanks in advance for any insights.

Seems to be working OK after several restarts from utility volume. Maybe "auto restart after power failure" in Energy saver server settings had something to do with it.

Macbook Restarts after Shutdown

hi,
just recently my macbook has been restarting after about 10-30 minutes after i shut it down. i have unchecked the 'restart after power failure' and it is not scheduled for and startups in the power saver pane in System Pref.
i was reading around and then reseted the PRAM but haven't done the SMC.
i have also just got an Elgato DTT tuner and Eye TV 3 that seems to startup at login even though i don't wont it to, are they related.
Any Ideas,
Cheers

Do you use any external display?
If yes, disconnect the monitor cable prior to shutdown.

Endless restart after spinning gear

I've got a MacBook Pro that continually restarts after about 45 seconds on the spinning gear at the gray Apple start-up screen. I've tried:
1. Holding shift on start-up
2. Resetting PRAM
3. Running DiskWarrior from the machine, but it says it can't rebuild because of a disk error or something
4. Running DiskWarrior off another Mac through Target Mode on the MBP.
I'm still currently running #4, but it's been going for a good 12 hours and so far the "Speed reduced by disk malfunction" is at 155 and is still "locating directory data".
I need to get some files off of the machine which is why I'm willing to wait this long.
Is doing an archive and install the next step? Is there a change that will corrupt whatever is going on more?
Any help is appreciated.
Thanks everyone.

You cannot do an Archive and Install on a drive with a damaged directory such as yours (assuming there aren't more extensive problems.) All you can do is reformat the drive unless DW is successful in repairing it.
Basics of File Recovery
If you stop using the drive it's possible to recover files that have not been overwritten with recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.
The longer the hard drive remains in use and data are written to it, the greater the risk your files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
In the future I suggest you adopt a backup strategy:
Basic Backup
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Intego Personal Backup (Commercial)
9. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete FireWire drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.
