Bootcamp partition shows up as grey "disk0s4" in Disk Utility

Hello everyone,
So I am a few days into this tiring and discouraging process of trying to get my iMac back to it's original working state. Here's to hoping for a solution:
Ever since I bought my iMac, I've been running OSX Mountain Lion with Win7 installed through BootCamp, without any problems. I recently wanted to increase my Boot Camp partition size from 80GB to 149GB because I was running low on disk space, and that was the start of many problems to come.
Here's what I tried first:
Make a backup copy of my OSX partition through Disk Utility's "Restore" tab (onto external HD 1)
Make a backup copy of my Windows partition through "Create a system image" in Windows Control Panel (onto external HD 2)
Use WinClone to backup a copy of my Windows partition
Erase Boot Camp partition in Disk Utility
Resize Mac OS partition to max
Create new FAT partition (149 GB)
Restore WinClone backup to the FAT partition (hoping it'll "fill up" the remaining free space)
I don't remember all the details, but all of this led to Windows not being able to boot properly, and then soon after, OS X wouldn't work either. The built-in Recovery HD somehow became unusable and showed up as grey in Disk Utility (too chaotic to remember how). After much trial and error, I was left with the Mac's built in Internet Recovery option, which I used to reinstall OS X Mountain Lion (on top of the existing Mac partition). Afterward, I regained the Recovery HD, and resized the Mac OS X partition to cover over the unusable free space that remained.
After that:
Ran Boot Camp Assistant to start the Windows installation process from scratch.
After the installation finished, I used "System Image Recovery" from a bootable Windows Recovery USB that I created.
Upon restart, Windows would not boot (which was fixed using the bootrec commands within Command Prompt off the USB).
This allowed Windows to boot fine, and it was exactly as it was before this all began.
Now, here are my current problems.
I believe the simplest way to achieve my original goal of extending my Windows partition would be to use Paragon's Camptune X, but upon running it, it tells me it can't find any Bootcamp configuration on my system.
While both OSX and Windows appear on the Startup Manager when I hold down the "option" key (which boot and run just fine), the "BOOTCAMP" partition that I would normally see in Disk Utility (under Macintosh HD) is now listed as "disk0s4", is grey, and "unmounted". It's also listed as MS-DOS (FAT), while it shows up as NTFS within Windows.
The Startup Disk preference pane lists Macintosh HD as the only choice.
I'm exhausted from the past week of repeated backup/reinstallations and trying to make this work. I've done my share of research and reading related forum threads, with no real solution. I am hoping "The hatter" will see this, as he's offered much info/advice on this topic on these boards, but I still haven't been able to resolve this issue.
Thanks for reading, anyone have any ideas?

By using Disk Utility to try to resize your Bootcamp partition you messed up your hard disk. You need to backup all your data from the disk, eraze and format your disk, and reinstall OSx, then if you want a new Bootcamp partition run Bootcamp Assistant.
Next time you want to resize the Bootcamp partition use CampTune, not Disk Utility.

Time Machine drive icon greyed out in Disk utility

Hi I'm using a 1TB WD Electronics external drive which is partitioned (265GIG used so far)
Macbook Pro btw
i use one half as a regular external drive and one half to take care of TM back ups
i recently plugged in the drive and the Time Machine back up has failed and there's no TM icon on the desktop and the TM partition is greyed out in Disk utility
i've turned TM off at the moment
any ideas to get TM running again?
thanks

Disconnect the drive and reconnect it. Any change? If not, test it with another Mac.

All my external Hard Drives stopped showing up in both Finder and Disk Utility

Hello there.
i have this strange issue that occured just out of nowhere without me (knowingly) having contributed anything to it.
yesterday i launched my iMac and my external firewire drive wasn't showing up in neither the finder nor on the desktop. i instantly thought about a hard drive crash, but soon tried other things to evaluate (or not) my guess.
for instance, i unplugged the drive waited a few minutes before i plugged it in again. since this iomega drive is also equipped with a regular usb port i also switched cables and tried connecting it via the iMac usb sockets as well as via an usb hub without any luck. the drive still won't show up. so i launched the Disk Utility, to see if the drive needs some checking/repairing, but to my surprise it wasn't showing in Disk Utility either.
thus far i only considered this to be an issue with only this particular external drive, but when i eventually switched on a 2nd external drive (this time an usb drive i use for Time Machine) that drive also refused to show up in either the Finder or the Disk Utility app.
curious as i was, i then fired up a 3rd and 4th external drive and now had all 4 drives running at the same time. none of which were showing up, just as if they weren't even connected with the iMac.
this strikes me as more than odd. i've heard about hard drive failures and crashes. they just occur over time. maybe and under some very strange coincidences it is possible that two external hard drives quit their jobs at the very same time, but seriously .... 4 of them?? i hardly think so.
well, maybe it's the iMac's usb/firewire controller that's causing the trouble, i thought. but then again, my other connected devices (iPhone, iPad, Printer, Scanner, eyeTV) are functioning and get detected just fine as far as i can tell.
i have no idea what's going on. i dismiss the idea of 4 external drives having crashed all at the same time just as much as i don't think that the iMac's usb/firewire controller has got any issues. re-formatting any of the 4 drives is out of the question and even if i'd consider such desperate measures, the Disk Utility wouldn't let me re-format anything anyhow, because the drives aren't listed there. i wish i could just use my Time Machine to resolve the issue but, as i mentioned earlier, i can't access the Time Machine because it also won't show up.
please, i need an expert's help here. please, somebody bring back my 4 external drives so i can access them in finder again.
any help will be much appreciated.
thank you in advance..

Launch the Terminal 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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
diskutil list
Post any lines of output that appear below what you entered — the text, please, not a screenshot.

Time machine greyed out in disk utility

I want to erase a time machine backup to use the HD on a different system, yet it's greyed out in disk utility.
The HD still works fine and I can restore files from it and time machine itself still works backing up to it.
I cannot however erase it using disk utility.
Here's a screenshot.
What am I doing wrong?

You've got other problems in addition to the Erase being grayed out.
The menu icons at the top are not right either. The Info, Burn and Eject menu items should be active also.
I'd suggest quitting Disk Utility, reboot your system and trying again.
Post back if that doesn't fix it.

When I boot holding option, both Mac and Bootcamp partitions show up, but disappear after 2 seconds.

I recently swapped out my HDD for an SSD in my 2007 MBP. Hardware installed fine. I installed Mountain Lion from a time machine backup (of the same machine). I made the Windows partition in OSX, then installed Windows 7 on the partition it had made. In Windows, I updated Bootcamp to 3.3.
Everything seems to work fine in both OSX and Bootcamp from what I can tell. The problem is, when I boot and hold option to choose my boot drive, both drives appear and then disappear in about 2 seconds. They disappear with a "poof" animation, as if you had dragged an app off of the dock. If I'm fast enough, I can choose the boot drive before it disappears.
I tried once again reinstalling OSX from my last time machine backup (prior to the SSD swap), and the problem persists.
I thought it might have something to do with NTFS 3G and MacFuse, because I'd heard that they cause a bug where the bootcamp partition won't show up under the "startup disk" preferences pane. When I uninstalled said programs, bootcamp showed up under there startup disk options, but the problem persists.
Any ideas?

Actually, this is just getting weirder.
Disregard my edit above. Clicking once doesn't have any effect on the drives. But the drives disappear only coming off of a RESTART from OSX. If I Shut down fully, the problem is solved. Likewise, if the drives have disappeared after a restart and I am forced to turn off the computer by pressing the power button, upon boot up the drives no longer disappear (Regardless of any action I take).
It would seem that the drives are disappearing due to something during the restart process.
Okay: Here are some workflows that might shed light on the situation:
Boot to Mac -> Shut down -> Alt boot : DOES NOT DISAPPEAR
Boot to Mac -> Restart -> Alt boot: DISAPPEARS
Boot to Mac -> Shut Down -> Alt boot -> Boot to Windows -> Shutdown or restart -> Alt boot : DOES NOT DISAPPEAR
Boot to Mac -> Restart -> Alt boot & fast select -> Boot to Windows -> Shutdown or restart -> Alt boot: DISAPPEARS
Boot to Mac -> Restart -> Alt boot & disappears -> Turn power off -> alt boot: DOES NOT DISAPPEAR
So the core culprit is something to do with OSX restart. The method of shutdown during windows doesn't seem to matter.

Volumes Greyed out in disk utility

tried to do averify and repair disk when it finished the volumes/partitions are greyed out

Where are you running Disk Utility from - the boot
system, or an installation disk?
from the actual system yea, I understand about thenot being able to unmount a volume you are on but the disks that were doing it were not the system disk so I was able to do repair and verify disk to mount/unmount, they would go through fine but the volume would stay greyed out not the actual disk itself. One is a int HD the other was a ext FW 400 drive. I have haad a lot fo problems laltely so if you want to read all the thiings that have happened here they are. OH thanks so much for your help
OK before I forget the way all this happened I will write it all down so here it is.
I was trying to hook up a ethernet conn to a muse receptor (music gear)I realized after I wasnt successful setting it up that my main Macintosh HD was missing from the desktop , When I would do a search I would see it and could acess it but it was greyed out. I did repair perm it was ok. I tried moving it to the sidebar ,no luck. I then installed a OS x on an ext HD and repaired and verified the disc that way to unount and remount all was good. WEnt back to real Os ,still not there. Then SOmeone in an email said to run a apple script
"System Events"
set visible of (choose folder with invisibles) to false
end tell when I did I then realized that now my other HD is missing from my desktop and I also accidentally made it go poof from the side bar too. now if I go to finder and try to hit show HD nothing happened.
SOMEONE PLEASE HELP!
More info if I do command shift G for , /Volumes/Macintosh HD/ it goes to a shortcut for it and if I do it for the Audi HD I get a short cut to it but this time it is a network shortcut icon
Also My iDisk which I never use is stuck on my desktop and cant get rid of it
I think what happened is maybe I got my user and my main hard drive volume switched up cause if I look into that Macintosh HD and go to users/myname/desktop it looks the same as my current desktop
OBviously these are all guesses
Update
Now when I hit the audio shortcut Icon it says it cant be found and to insert the disk or connect to the sever volume and wait for it to appear on the desktop

I can't find my windows partition it just shows as Macintosh HD. Although when I go into bootcamp it shows there is still 20gb assigned to windows but I screwed it up as I tried to extend the amount of GB I allowed to windows without reinstalling it. However I don't know what to do in Disk Utility now?
Please can someone help. thanks

Yeah you messed up your system. You can't expand, shrink or in any other way do anything to the Windows partition as that will cause it to become non usable and then can't be removed and put back into the Mac partition.
Your only option now is to save all your files, with Time Machine or just copying them to an external drive, and Wipe/Erase/Re-Partition the complete drive and reinstall OS X Snow Leopard.

I create a new partition in an external hard drive with disk utility. Now it says mounting disk and it's taking forever. Is that normal? Please help!

I have an external hard drive from seagate. Tonight I decided to give it a try and add a new partition to it so I could have a bootable version of mountain lion in it it just in case of emergency and no internet. After creating the partition, disk utility says "mountain disk", and its been doing it for at least 20 minutes and not moving... Any ideas? btw, now the external drive is not even showing on the left-side bar...
Thanks!

I would try reformatting the drive and creating the partition again. Make certain that you erase the drive and format it as "Mac OS Extended (Journaled)" and the partition the drive.
What you describe is not normal... try again.

Grey bar at startup - Mac HD is greyed out in Disk Utility - Can't be repaired? Need to salvage my data!

Mac Book Pro -
My MacBook Pro (2008 Model) has been unable to start up - upon the start up screen when the grey Apple logo appears, I get a loading bar below it.
After about 15-20 minutes when the bar is almost complete the machine shuts off. There seems to be no way around it.
So I booted up my laptop in recovery mode, and opened Disk Utility to check my if there was something wrong with my drives -
my Macintosh HD (under the TOSHIBA drive) is greyed out. When I hit verify/repair it returns error messages and it remains greyed out.
I tried multiple times and a few times it stopped being greyed out on the sidebar, but even then it wouldn't let me verify or repair.
Not backing up my data recently is my obvious fault here, but I just wanted to know if there is ANY way to salvage my data.
Things I've tried:
1) Recovery Mode
     -Veryify/Disk Repair doesn't work
     -Time Machine can't seem to access my HD either (greyed out)
2) TargetDisk mode
     -I connected my MacBook Pro via firewire to my Mac Pro in TargetDisk mode and no Hardrive shows up on my finder.
Any advice appreciated, going to try and take it to a tech shop on Monday.
Thank you!

I would take out the HDD and install it in an enclosure and then connect that to the Mac Pro and see if there is any success.
If not, then look for data recovery software on the Internet. Most will have a 'trial' version that will indicate if the software will be successful or not, so you do not have to commit funds without knowing if it will work or not.
The last option is a professional recovery service. There will be no guarantees of success and the costs will be very high.

Permissions buttons greyed out in disk utility

In the disk utility, the "verify permissions" and "repair permissions" buttons are greyed out no matter which disk is selected in the left-hand pane. Does anyone know why this is so and/or what alternative ways there are of repairing permissions?
The problem persists whether I start the computer from the recovery system (command-r) or not.
Thanks.

Hi again and thanks for bearing with me!
I haven't done any cleanup, however there are only a couple of files in /Library/Receipts/, all very old, so I'm guessing the receipts are kept elsewhere after OS X 10.5, since the KB article you referred me to explicitly refers to pre- 10.5 systems.
The disk utility log in console and the info in the disk utility itself both give exactly the same info, which is basically what you’ve given:
          Owners Enabled :           Yes
          Can Turn Owners Off :           Yes
          Can Repair Permissions :           Yes
          Can Be Verified :           Yes
          Can Be Repaired :           Yes
          Can Be Formatted :           Yes
          Bootable :           Yes
          Supports Journaling :           Yes
          Journaled :           Yes
          Disk Number :           0
          Partition Number :           2
If I understand correctly, this would all mean that I should be able to click “verify permissions” in the disk utility, but for some mysterious reason I cannot.
However, in the KB article (http://support.apple.com/kb/HT1452) I notice it says “While started from an installation disc in Mac OS X v10.5 and later, a user's home directory permissions can be reset using the "Reset Password" utility.” Does this mean that if I use the reset password utility I can reset permissions and therefore not need to use the repair permissions function of the disk utility? Or is this something completely unrelated to what I’m trying to do?
I really appreciate your help very much - the only reason I wanted to repair permissions was that it was one of the recommended solutions to a problem I’ve had with microsoft office, which thankfully has now been solved after reinstalling os x and office, but it still bugs me that the option to repair permissions seems unavailable!
Anyway, it's not the end of the world if it can't be solved, you've helped me learn a lot in the process!

When trying to format my internal hard drive, it's greyed out in Disk utility?

I'm trying ot format my computer and wipe everything off before giving it away, but Disk Utility has everything greyed out and won't let me choose my hard drive. I have the original CD and everything that came with the computer. How do I fix this fast?

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Mac HD greyed out in Disk Utility

Hey,
This all started after Mountain Lion, which slowed down my MacBook a lot. I tried to do a clean install and reformat my HD, and doing so it removed the partition already on it. When I went to restore the HD, every option is greyed out except for Verify and Repair Disk (which I have clicked on numerous times to no avail). I cannot even add a partition to the Hard Drive. This Hard Drive worked fine until I clicked erase (in which it gave me an error), and I just want to create another partition (which is also greyed out).
I don't care if everything gets erased, frankly I just want my Mac back to normal. I do have a Mountain Lion USB, but that does squat. Thank you Mountain Lion by the way for this long day in which my Mac still isn't fixed.
Any help is appreciated, I am new to Mac, just moved from PC which looks pretty good right about now.

While we all have MacBooks in this forum most of us don’t run Mountain Lion. There's a Mountain Lion Support Community where everybody has Mountain Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/os_x_mountain_lion

Apple/Grey Screen Stuck - Disk utility - back up

Hello,
So I was on my computer and it randomly turned off and turned back on and stayed on the apple/grey screen. I've done the vram reset and ended up where I can boot up the installation disk. I've gotten to where I can access the disk utility and repair/verify disk permissions but ended up getting the error code: 'Error: no valid packages.' From my hard drive, all I need are pictures and videos that I had just backed up the day before. Could someone help me (easiest way for me to follow is through steps) on how to just back up specific files or folders (i.e. pictures folders)??
Thanks again for your help!
