Can't boot up into OS X after attempting to partition the hard drive from Windows

I recently installed Windows 7 on a partition of the hard drive in my iMac. In an attempt to make the Windows partition bigger I did something to the OS X partition and now I do not recieve the option to start up in OS X when I hold option down on the boot up screen. Is there any way I can fix this? I checked the hard drive and ~300mb (the size of the OS X partition) is still being used but I can't access it.

Your question seems to be a MS Windows question. If you use Boot Camp then post there. If you use Parallels or another virtualtization app to run Windows please post in those forums. Most users on this forum don't use Windows, some do but most do not.
Best of luck.

  • Can I put the hard drive from my unrepairable iMac into another equivalent iMac?

    THE LOGIC BOARD IN MY OLDER IMAC IS KAPUT.   CAN I SIMPLY PUT THE HARD DRIVE FROM MY FAILED IMAC INTO A WORKING EQUIVALENT IMAC?   ( I SEE PEOPLE SELLING THE SAME IMAC ON CRAIG'S LIST FOR $150.)

    Hi.
    Yes, you can install the drive from the old iMac into another same-model iMac and it should have no problem booting.
    Optionally, I would suggest you search online for a FireWire external drive enclosure. Take the drive out of your old iMac and install it into the FireWire drive enclosure. Now you can use your old drive as an external, bootable hd on your replacement iMac, or on any other Mac that you might purchase in the future.
    Of course, you could swap the drive from your failed iMac into the one you buy on Craig's List... then put the drive you take from that into the external drive enclosure.
    I suggest a FireWire enclosure because the older iMacs, the PPC models, can boot from an external FireWire drive, but I believe not from a USB drive.

  • If i install microsoft office after partitioning my hard drive for windows, will it be available on both sides of the partition?

    If i install microsoft office after partitioning my hard drive for windows, will it be available on both sides of the partition? Will it be universal for the computer or would i have to install it on both operating systems? Or, if I install office BEFORE partitioning, will it be available on both platforms after i partition?

    If I understand your questions correctly, then I'm inclined to say no. Office for Windows and Office for Mac are two completely different applications. if you run via BootCamp, only one partition will boot.
    If you want to run Mac and Windows at the same time, you could do what I did:
    Get Parallels
    Install Windows as VM on top of Parallels
    Install Office in Windows
    Now, you can run your OS X, jump into Parallels' WIndows and use Office that way.
    It needs a lot of RAM, 4 is a bare minimum to realy make it sensible, 8 wouldn't hurt.

  • How can I remove the hard drive from an iMac g4 before recycling it?

    How can I remove the hard drive from an iMac g4 before recycling it?

    There are take-apart guides online.  For example
    http://www.xlr8yourmac.com/systems/imac_g4/imacg4_takeapart.html
    However, you can also consider securely erasing the hard drive instead.  You can do this using a Mac OS X installation disc with a version that your iMac G4 can boot from the optical drive.  If this is a viable option, please post back (include Mac OS X version on installation disc).

  • I have a 15" MacBook Pro with Mountain Lion installed.  I have partitioned the hard drive into two partitions.  Is it possible to install Snow Leopard on the second partition?  If so how do I do it?

    I have a 15" MacBook Pro with Mountain Lion installed.  I have partitioned the hard drive into two partitions.  Is it possible to install Snow Leopard on the second partition?  If so how do I do it?

    If your MacBook Pro had Snow Leopard on it at one time then sure. (Early 2011 or earlier)
    How to erase and install Snow Leopard 10.6
    Obviously choose the second partition to install into. It has to be OS X Extended journaled formatted in Disk Utility (BootCamp software makes it a MSDOS/FAT32 formatted partition if you used that to partition with)
    If it's a Early 2011 or Late 2011 that came with 10.7, it's possible, but it's not easy.
    https://discussions.apple.com/thread/3264421?start=0&tstart=0
    If you can't install Snow Leopard, there is a thread over at MacRumors how to run Snow Leopard in a virtual machine program under 10.7 or 10.8

  • How much does Premiere Pro and After Effects rely on the hard drive it's installed on?

    This may be a really dumb question, but how much does Premiere Pro and After Effects rely on the hard drive it's installed on if all your video files, assets, disk cache, etc are on different drives than the one the program itself is installed on?
    The reason I am asking is that I currently have a "relatively" slow Sata II SSD for my C drive that has just my OS (windows 7 64bit) and programs (adobe editing programs, no games) installed on it and nothing else. All of the files used in my projects are saved on either a very fast Sata III SSD or a slower HDD depending on what the files are. For example, disk cache on the Sata III, stills on the HDD.
    Being cyber monday I have the opportunity to buy another very fast Sata III SSD to replace my current Sata II SSD C Drive (just OS and programs). Both synthetic and real world benchmarks show a near double in performance. I just want to know if anyone thinks the upgrade is even worth it because for all I know there won't be any increase in performance since no videos, still, cach, etc will be stored on the C Drive.
    The alternative is to get a second monitor because I currently only use one 21" monitor.
    I suppose another alternative would be to not buy anything on the cyber monday deals and just save money for something else.
    Any advice or input would be greatly appreciated. Thanks!

    Thanks Alex! I think you are right about not being able to notice the difference between the SSDs. I ended up finding a deal to get about $80 off a great monitor that I've been looking at for a while and decided to pull the trigger on it. I thought about it and realized that there have already been a bunch of times where I want to watch a tutorial on youtube and follow allong in AE or PrePro, but have to keep switching windows. I also frequently want to have my video preview on a separate monitor so I can have a taller timeline window. This monitor will help a lot with that. Thanks again for your help!

    It is not showing on the Desktop or the left colomn of Finder (Set to do both in Finder Prefernces) and is not showing up under the Disk application under Utilities (Sorry can't remember the name off the top of my head!)

     ...I'm starting to think it is most likely NTFS, am I looking at needing an Application to read the NTFS partitions on the drive?
    You should be able to read NTFS formatted drives, just not write to them. For that matter, USB Flash drives generally come formatted NTFS for use with PC's and they have to be able to mount on a Mac in order to reformat them for Mac use. The Windows utilities supplied on those Flash drives will be deleted when the drive is reformatted for Mac use so I routinely copy them to the Mac desktop first before reformatting.
    You might look into something like this http://eshop.macsales.com/item/NewerTech/U3NVSPATA/ if the enclosure is an issue. It looks weird but it works.

  • Do I need startup discs to upgrade hardware on MacBook Pro or can I restore the hard drive from from a Time Machine backup?

    do I need startup discs to upgrade hardware on MacBook Pro or can I restore the hard drive from from a Time Machine backup?

    Ok, well go and grab a small 2.5" hard drive enclosure so you can put the new drive in & temporarily use it like an external hard drive.
    Download Carbon Copy Cloner or Super Duper and make a bootable clone of your current HDD on the new HDD.
    Once that's done you can test the clone by booting from it. To do this hold Optioni while booting to select the external (new) drive. If everything looks ok, you can go ahead and swap over the HDD's.
    So much easier.

  • How can I erase (or remove) the hard drive from a dead Time Capsule?

    How can I erase (or remove) the hard drive from a dead Time Capsule?

    I found this having had the same problem...
    http://forums.macrumors.com/showthread.php?t=553818
    Having removed the hard drive I'm finding I can't reformat it. I manage to mount the HD but Disk Utility crashes when trying to format (HD attached to Mac via Newer Tech. SATA cables to USB) and causes what I think is a kernal panic on my Mac which hard crashes. I see 3 partitions when attempting to mount one of which is AFP. Anyone got any ideas about how to do this? I've dug around but the only progress I've made is to note others have had to work around ACL's when replacing the logic board of the TC. Not sure if this even relates to the problem. However the tool for doing this seems to have been removed from SL. (Forum references to this procedure all relate to 10.5).

  • Can I bring files from a NTFS formatted external hard drive (from Windows XP 32 bit desktop) to my new macbook pro retina?

    Can I bring files from a NTFS formatted external hard drive (from Windows XP 32 bit desktop) to my new macbook pro retina?

    What are these files you are trying to copy over?
    If they are program specific and there is no program on a Mac to read them then you'll have to find either a Mac version of that program or one that does the same thing and can read those files.
    The file extension should not change just because you connect a NTFS formatted drive to a Mac computer. A Word Document is still a .doc/.docx ad the same for all other office type programs. Music files with an extension of .MP3, or whatever, should read the same on both system. Same goes for all other files like images with a .JPG extension.
    Yes I would network them.
    I would not use Migration Assistant. There is nothing on your Windows PC that can be used on the Mac other than your personal data files. No programs or settings can be carried over from Windows to OS X.

    Also, when I view the files from the external hard drive, they show up as .nbz and are not recognized by any program on the Mac. Should I just abandon the hard drive option and start sharing files through the LAN approach?

  • Can the hard drive from the Time Capsule be used as USB drive only?

    My Time Capsule "router" kept losing the wireless capabilty, so I purchased an Airport Express (with the dual-band router).
    I'd like to salvage the Time Capsule hard-drive portion and connect it to a USB port.
    But when I plug-in the Time Capsule, the light blinks yellow suggesting some configuration problem.
    When connecting to a USB port, my iMac will not detect a new device.
    Can the Time Capsule hard-drive be used separately from the router?

    Can the hard drive from the Time Capsule be used as a USB drive only?
    Sorry, but no. The Time Capsule is a network drive, so it must be connected to a network using an Ethernet or wireless connection. The USB port on the Time Capsule is there only to add additional storage capacity.
    Can the Time Capsule hard-drive be used separately from the router
    Yes, you would configure the Time Capsule in Bridge Mode to do this. If you do not need the wireless capability, you can turn the wireless off on the Time Capsule.

  • Can I put the hard drive from my Lacie External HD into my 1.25 G4?

    I have a 1.25 GHZ G4 and would like to increase it's internal storage. If I can I would like to put my Lacie External HD into my machine (120 GB) and then purchase a new larger HD to place in the Lacie box. I'm not sure if this is possible? What do I need to check when looking for a new HD for my machine? Any help would be appreciated.

    Assuming that the hard drive in your external case is a 3.5 inch unit, it will work just fine. The only thing you have to do is make sure that your jumpers are set properly (master on your OS drive, slave on your secondary drive). There is a possibility that you will have to purchase a different hard drive cable, unless your machine is already setup with a dual cable & the stack bracket (you also have to make sure that the 'master' drive is plugged into the end of the cable & the 'slave' drive is plugged into the middle of the cable). I have never had a problem putting a larger hard drive into an external case (all of mine have been firewire). I hope this helps.

  • Can I plug the hard drive from my Time Capsule into my PC?

    My laptop's hard drive recently died and the chance of being able to recover any data from it is pretty slim. To make matters worse, i've been meaning to buy a new Time Capsule for a while as mine is no longer functioning correctly (won't let me connect even with a solid green light).
    I'm hoping that's the fault of the rest of the Time Capsule, and not the hard drive and its contents. So, would it be possible to plug the Time Capsule's hard drive into my Windows PC and somehow recover the data from there?
    Thanks!

    The only files you can recover are ones you put there.. so the only way and the only person who knows the answer is you.. where did you put the files?
    Did you put them in a new folder under the share, data.. then that is where they will be.
    If you put them inside the sparsebundle.. you are dead. But if you created a new directory inside the sparsebundle you might still get access to it.. there is only one way to find out.. have a go.. !!
    BTW if you did this, that is why you have issues.. putting files inside a sparsebundle will destroy it. Not a great idea. But it is allowed.
    Who can know these things.. YOU.. and YOU ALONE.
    You might find it cheaper in your case to repair the TC..
    If it is Gen 1 or 2, type "Time Capsule Power Supply" into ebay.. without the ""
    There are some there to help you fix it.
    Or a repairer could help.

    It is much easier to get your files back from a working TC.

  • Can I swap the hard drive from MacBook Pro 17 (2009) to MacBook Pro 15 (2006)?

    My MacBook Pro 17 (2009) died. Pushing the power button gets no response. I had had problems with it for some time turning it on, it usually taking many many tries. Plus when I'd try to do a restart after updating software, instead of doing so it'd shut off super quick with a *pop* sound. There was never any of the typical hard drive going bad sounds I've read about and seen in videos. Since it has refused to turn on I've gone through every suggestion I can find to get it to turn back on. Unhook the battery and try starting from just the power cord; the shorting the power pads move; some thing undoing the battery, counting to 10, and then the next steps now escape my memory, but doing more counting to 10 inbetween; unplugging the battery and leaving it sit for 2 days with no power cord plugged in either, then hook it to a power cord and turn it back on; and so many more.
    Also the symptoms just before this fiasco were as follows: I had a CD in the internal drive and was browsing through the images on it via the handy previewer using the space bar. Then I decided to quite, tried ejecting the CD by dragging the icon to the trash, and nothing. I tried again. The same. Then I pushed on the eject key, with the ejct icon popping up on the screen momentarily, but still nothing. Then it appreared as though some things worked and other things were not working. In my frustration I went to the Apple menu and clicked restart with a wince knowing it was going to take forever to turn back on. It did the usual quickly off with a *pop* and made super short lame attempts to turn back on when using the power button. Of course the CD kept trying to spin for a split second and then the little indicator light on the front would go out, then no noise at all.
    Since I do not believe it is the hard drive (of course I could be wrong not being a Mac nerd at all), I was wondering if I can switch the hard drive to my Macbook Pro 15 (2006)?
    I tried this, but it would not read the hard drive. Just a blank grey screen. If it is possible to do this swap, what are the exact steps to do? Please answer like I'm completely illiterate on this, because I really am. I'm super scared of losing everything on the dead MacBook's hard drive. Yeah yeah, I know: then why have I not been backing things up? I had the week prior. Believe me I WILL be doing it daily from now on if I get this mess straightened out!

    OGELTHORPE really sorry to keep bugging you, but it's obvious you know what you are talking about and I'm stuck on thin ice here getting this fixed, because there are no authorized Apple reps here. I would rather shoot myself for messing up, then to trust someone who "says" they can fix my Mac down here.
    I checked out a company owned by ebay that is the same down here, called MercadoLibre. There are quite a few adapters listed there. I'd like to give you links for some and was wondering if you minded taking a look to tell me if any seem to fit the bill. Some have specs in English, others don't. (Google translater is my friend!)

    These are all cost effective enough that I don't care the price - cheap, expensive - whichever will work the BEST!
    I've also looked for the 7200 rpm HDD, and although I found some, I'll be danged if they are not 3.0, instead of the 2.5 that I have. Grrrr! I was willing to spend the $90 for 1tb... or being the non-techie that I am, can this 3.0 go into my 2006 MBP??
    Just so you can see what all is listed right now:
    http://listado.mercadolibre.com.uy/7200-rpm-hdd-2.5-macbook-pro
    Another newbie question: How do I check what the amount if RAM is presently installed in it? (I might be a greenhorn, but I take pride in not being a dumbie and I learn when taught)
    Right now, I'm willing to spend almost anything. I want a few files that are on the HDD at the moment that I was stupid and did not backup on my external. One file I worked on all day due to the dimensions I had to design it at and each effect took a long time to render. I really don't want to do that one again!.. I'm also willing to spend anything that won't cost me the price of a new iMac. Figure that should be the next one I buy that is affordable, but won't be overworked like the MBP was.
    Once again, thanks much for all of your help!
