Lost Windows 7 boot option after creating new partition

First of all im new to Mac os.
i have installed windows 7 using boot camp and after it i tried to create a new partition from the main mac partition and it was created successfullly however now the windows 7 boot option is not available for some reason.
how can i have this option back?

You broke it by adding the extra partition, remove Boot Camp (read the directions as to how) and start again. Do not add partitions next time.
Do not use Disk Utility to remove the Boot Camp Partition, use it to remove any extra partitions.
Backup your machine now.

  • Repairing Boot Camp after creating new partition

    I'm running OS X 10.8 and Windows 7 x64 Pro.
    After properly setting up Boot Camp to dual-boot Windows on my Mac mini, I decided to test whether or not it was true that creating another partition (a data partition for OS X) would interfere with Boot Camp.  Wikipedia claims it does interfere but without citing a source, whilst the Boot Camp documentation itself only specifies that the disk must be a single partition _prior_ to setup - there's no mention of whether the disk must be _kept_ that way afterwards.
    I opened Disk Utility, reduced the size of my OS X parition from 420GB to 80GB, and created a new partition in the unallocated space.  Here's how it looks now:
    When I attempted to proceed with the process, I did receive a warning that doing this (and I quote), "may" cause problems with Boot Camp.  Seeing as it was inconclusive, I thought I'd give it a shot - nothing ventured…
    Of course, it borked Boot Camp, otherwise I wouldn't be posting here.  Whilst OS X boots just fine, the Boot Camp partition now no longer shows up in the Startup Manager, though it does in the Startup Disk prefPane.  If I do attempt to boot into Boot Camp, I receive the following message on a black screen:
    No bootable device --- insert boot disk and press any key
    The advice given to someone who had this same problem was, "fix your damaged Boot Camp volume."  But I'm at a loss as to how to do that.
    So, anyone know how to proceed now so that I can keep my partitions as is, whilst fully restoring normal Boot Camp functionality?

    Hi,
    @Christopher Murphy:
    Okay, you seem confident.  Let's give this a shot.  I use the command-line myself for the odd thing, so I'll try not to bail.

  • Lion Recovery disappeared after creating new partition

    Hey there-
    Today I created a new partition on my MacBook Pro hard drive in order to install a separate Snow Leopard partition on my machine... Prior to creating this partition, I had my regular Mac HD partition, Lion Recovery, and a BootCamp partition to choose from when booting up. After creating the new partition, I was able to install Snow Leopard on it without a hitch, but now when I reboot and hold the 'option' key to choose the boot source, only the Mac partition, Snow leopard partion, and BootCamp partition show up... Where did Recovery HD go? Is it still on my machine somewhere?
    Thanks!

    Well like I said, I already have file redundancy with my two computers and if the whole thing dies, I'll just do it all over again... I'm not too worried about that. But yeah, probably a good idea to keep a copy of the installer. I did download it overnight but by then my problem was already resolved, haha. *puts it in safe keeping*
    I really only cared for Recovery HD for two things: Find my Mac (it's needed to boot into Guest only mode) and to do file system repairs in Disk Utility if necessary.
    When I get a bigger capacity hard drive one day, maybe I'll clone the whole setup but for now I really only wanted that partition back for the two things I mentioned above.
    But again, I still insist that the method in the link is a much faster way, step 1 being almost unnecessary.

  • Repairing bootcamp after creating new partition

    Like others who have posted here, I had two partitions, MacOS and Bootcamp that worked just fine.  I then added a new partition because I need a "D" drive in Windows configuration to be able to install a particular set of programs that rely on such a configuration (long story and perhaps there was a better way).  Once I added the new NTFS partition and rebooted, I no longer see the Windows drive as a a boot option.  I don't know if the command line "sugo" utility and syntax  that I've seen in postings here applies to all such situations but if anyone can guide me through it I would be very grateful.  Thanks

    No worries.  Here you go.  I'm glad you can interpret this stuff.

  • After creating new partition with iPartition, on a nonbootdrive, I can no longer see any files stored on that drive.

    I have a Hitachi disk that I use for media (photos, videos, etc..)
    After using Ipartition to create a new partition on this disk, none of the files are visible any more.
    The disk was never partiton before so this was the first partition created.
    When I launch iPartition again, I notice that I now have a Microsoft FAT or NTFS type partion and a HFS partiton however there is no data at all under Finder.
    What should I do to recover my files ?

    you don't need 3rd party to shrink and create a 2nd partition.
    One partition is still partition, and there are others like Lion Recovery, GUID, EFI on there.
    Repair the drive and make sure iPartition does what you want and current. Or just use DU instead.
    And backup.

  • Help! Need to recover lost hard drive data after creating a partition!

    So, I'm the world's biggest idiot, and I was trying to reformat my hard drive so that I could bring the documents from my Mac to my PC.
    All of the docs were perfectly organized in folders and subfolders a long time ago, and once that had been done, I deleted everything off of the MacBook itself. I never thought I'd have to move all of the docs to a PC, but alas, nothing ever goes the way we plan now does it?
    Anyways, I created a FAT 32 partition not realizing it would delete everything I already had on the hard drive, so now I need to recover all of that.
    Is there ANY way that I can recover all the data I lost?
    Pls respond.

    When you create a partition, the partition is the erased so all content is lost.  There are data recovery services that may be able to recover the material, but they are very, very expensive, if they can even succeed with this kind of erasure.
    Check and see if there are any hard drive data recovery services in your area.

  • Recovery HD gone after creating new partition (to install Snow)

    Hey all,
    So I needed to reinstall Snow Leopard on my Macbook Pro, so in Disk Utility I shrunk the main partition by about 20gb and then installed Snow Leopard on that partition, so now I can dual-boot Lion and Snow Leopard.
    But now the Recovery HD partition is gone. Is this normal and any way to get it back?

    Well like I said, I already have file redundancy with my two computers and if the whole thing dies, I'll just do it all over again... I'm not too worried about that. But yeah, probably a good idea to keep a copy of the installer. I did download it overnight but by then my problem was already resolved, haha. *puts it in safe keeping*
    I really only cared for Recovery HD for two things: Find my Mac (it's needed to boot into Guest only mode) and to do file system repairs in Disk Utility if necessary.
    When I get a bigger capacity hard drive one day, maybe I'll clone the whole setup but for now I really only wanted that partition back for the two things I mentioned above.
    But again, I still insist that the method in the link is a much faster way, step 1 being almost unnecessary.
    The 10.7.2 update even includes this exact process in the background to replace the old Recovery partition with its newer version.

  • Windows boot option icon disappear!

    Hi, I successfully installed Windows XP SP2 with bootcamp.
    I started successfully Leopard and Windows many times, then I installed VMWARE Fusion and I choose to use the fisical Windows partition as a virtual machine.
    Now I can choose to start windows or leopard only from bootcamp options in the preference of leopard or systemtray in windows: pressing "alt" button at startup shows me only MacOSX System and disappear windows disk Icons....
    How can i reconfigure boot option to show the windows icon too ? I don't want to reinstall beacuse it runs correctly ! it seems only a boot configuration...
    The console of leopard report something as com.appl.system service xml boot options do not match...
    Sorry for my bad english and thanks in advance for your help!

    I guess, I have to explain more...
    I know the way of selecting the boot drive( the way you mentioned)... My problem is after creating new partition with disk utility... I cann't any more boot to Win at startup. It seems that the Win startup partition is removed, but when I check it from OS in my FINDER, I can see the bootcamp partition and all my date inside..
    So, I need to know how can I again activate booting option to Win at startup(or something like this)

    Hello Kaj_R.
    If you change the volumes it is quite likely that the recovery partition will not function.  I suggest you create a set of Recovery Media before messing with the partitions.
    This document can help you create the recovery media.
    Have a great day!

  • New Virtual hard disk wizard hangs after creating new vhd from huper-v manager on windows 7

    New Virtual hard disk wizard hangs after creating new vhd from huper-v manager on windows 7 workstation. 
    Windows 2008r2 hosts the hyper-v server. I can create VMs and VHD's when connecting to the server locally with the hyper-v manager. 
    The issue arises when I try to connect to the hyper-v server from my workstation which runs windows 7. 
    I have installed  The Windows6.1-KB958830-x64-RefreshPkg.msu that was suggested for windows 7 sp1. 
    I can connect to the hyper-v server, create vm's but  I cannot create vhd's  the gui just hangs with no errors in event log or on screen. 
    The files are there on the hyper-v hard drive but i suspect they are just created by windows as they are written and are not valid. 

    I've had just the same solution. Both did Hang Fixed size and flexible.
    Two parts were taken:
    1 - KB939820 for Windows 2003 server based domain controllers
    2 - disable using IPv6 on your NIC
    Result - both types of VHD's are created normaly.

  • Updated software on Macbook Air and bootcamp partition disappeared.  Windows boot option no longer appears.  Can I get it back and the data?

    Updated software on Macbook Air and bootcamp partition disappeared.  Windows boot option no longer appears.  Can I get it back and the data?

    Amy, is there a chance they could both be Syncing to another device that has the data erased?
    What are the sizes & modification dates on the files you found?
    Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."

    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

  • BootCamp cannot create new partition on drive free space.

    Hi Folks,
    I am hoping for some advice here. I am running OS X (10.5.6) and wish to use Boot Camp to created a partition to install Windows XP SP2 for some gaming. My machine is a late 2007 MBP 2.4GHz C2D, 4GB RAM, 340GB WD transplanted hard drive.
    I have about 180GB of free space for a new partition to be created for the XP install.
    When I fire up the Boot Camp Assistant tool, I am immediately informed of the following:
    "The startup disk cannot be partitioned or restored to a single partition."
    "Back up the disk and use the Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using the Boot Camp Assistant again."
    + I have never had more than one partition on this drive.
    + I installed the drive new with no partition and used a tool named 'Carbon Copy Cloner' to transfer data from the original drive onto this drive, the machine booted right away and I have been using it without issue ever since.
    + I have run Disk Utility to 'Verify Disk', 'Verify Disk Permissions' and 'Repair Disk Permissions' all ran with no problems and completed successfully.
    My question is, how can I make a usable backup copy of the drive to restore back to the drive after performing the re-format?
    Can I use the Carbon Copy Cloner software for this? I want to make sure that the resulting internal drive is bootable, etc.
    I have been running Time Machine as well and have a disk full of backups from that app, but I have no idea how to use it to restore the drive to it's current state after re-partition and format.
    Thanks in advance for any and all suggestions.

    So today I used the free "trial" version of SuperDuper to create a bootable clone of my primary internal drive.
    It was about 100GB and took a long time to copy onto USB 2.0 external SATA drive, but it worked.
    SuperDuper provided the option to make the copy the boot device as well. After reboot, I used OS X Disk Utility to erase primary drive.
    I then performed the operation in reverse, copying the entire contents back to the original location.
    After a reboot, I ran the Boot Camp Utility and received the same aggravating message which I received before.
    How can I be sure that I am actually re-formatting the target drive in order to consolidate free space? Is this my issue? When I performed the erase operation, I skipped the "zero out free space" step. Am I using the correct utility to prepare the target drive?
    Once again, any and all help is greatly appreciated.
    Regards,
    John

  • Problem in Creating New partition in Pavilion dm4 1217TX

    I have a hp Pavilion dm4 1217TX model laptop. I want to partition the hard disk (640GB) to separate the OS to the data. I think this is a very basic safety feature that will save my data in case of Windows failure (which is a very common problem). I have already split the C Drive and the new condition of my hard drive is
    System           199 MB       Primary
    C                        70 GB       Primary
    Unallocated   494 GB       Logical
    Recovery           32 GB       Primary
    HP Tools        103  MB      Primary
    Now I can't create partition in the Unallocated space because of 4 Primary Partition it already has. Now what can I do ? I can't understand that why it comes with four Primary Partition and without any Extended partition.

    Hi, there, I have the same problem with you, because of the OEM of the laptop, they have partitioned our hard drive in advanced, however this partition is not logical. As we know, when we install Windows7, the system partition and system reserved partition are set as primary partition without doubt, but how could they make the HP tools and other partition as primary partitino too. I'm very unhappy with this. I don't know WHAT are they thinking about. Every one who has a bit comptuer knowloage knows the rules of createing new partitions in Windows.  In my situation, I could only copy the data on recovery to C drive, then delete it. and recreate logical partition, then copy it back. Hope this could also help you.

  • IPhoto- no option to "create new library"

    Hi all
    When I try to import new photos into iPhoto I get the message that there is not enough space in my library to allow it.  I have searched for this issue alone on these message boards and have seen I need to check my memory (I have over 90gb free) and then to try "create new library" when opening with command and alt button, to see if there's any concerns in doing that.
    My issue is that I don't have the option to "create new library." it is not there at all.  I have already tried rebuilding it from this option but I still get the not enough memory warning.
    Can anyone advise?
    Thanks

    To create a new Library you hold the option (or alt) key when launching, not the command and alt keys
    However, ths message is bogus -  after all you have 90 gigs free - and usually implies a damaged database.
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

    Don't know. Never used it. You should probably post your question in the Boot Camp discussions
