HT5628 i did a mistake i chose wrong partition whlie installing windows

so it gives me an error massage " no bootable device- insert boot disk and press ant key : so i tried command-r ,, alt thing but nothing works what should i do ??

Reinstall Mac OS X. To do that, follow these steps:
1. Hold Command, Option (Alt) and R keys while your computer is starting to start in OS X Recovery, and open Disk Utility.
2. Choose your hard drive at the top of the sidebar, go to Erase tab and erase the drive.
3. Close Disk Utility and reinstall OS X. After reinstalling OS X, install Windows again in Boot Camp. Read > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf

  • HT5628 Is it possible to format entire hard disk and install windows 8 only in mac mini?

    Is it possible to format entire hard disk and install windows 8 only in mac mini?

    You can, but it's not recommended. If you are going to use Windows all the time, at least give some GBs to OS X, because you will need it to install firmware updates.
    Use Boot Camp Assistant to create a Windows partition. You can find it in /Applications/Utilities. Then, follow Apple's steps to install Windows 8 > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf You must use a 64-bit version, and note that not all Mac minis support Windows 8. Check if yours is supported > http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US
    Boot Camp Assistant will ask you to download the Windows support software onto a USB drive. You will need to install it in Windows, so it's very important to download it. If not, you will have problems in Windows.
    If your Mac doesn't support Windows 8, install the Windows version the site gives you

  • After I did Partition on my windows, I lost my mac os on booting option

    Hello everyone i need help,
    I installed windows 8 perfectly on my macbook pro (mid 2012)
    Then I restart my mac, and try to press option, I still see the mac os option
    But after I partition my disk (the bootcamp disk) i seen 3 accessible disk in my computer
    Because i dont like it, i try to delete the partition letter,( I did not formated it!)
    After that I want to get back to my mac os, but after i restarted my mac, i cant find my mac os in option
    I still can see the partition for apple in disk management, but it doesn't show in startup
    Please help, thanks for ur reply
    Sorry if my English is bad

    You can't partition a Boot Camp partition. Nor can you add a third partition to a disk containing a Boot Camp partition. If this is what you did you have messed up your hard drive configuration. You will have to erase your drive, format your drive, reinstall OSX, then run Boot Camp Assistant to create a new Boot Camp partition, then install Windows.

    Good morning to all of you
    I have A mac and I did the mistake of upgrading my Lightroom 5.4 to 5.6 Now I can't import anything it says "Could not find namespace: AgCreativeCloudUtils"
    Could anyone help me resolve this problem?
    Should I uninstall the program and reinstall it
    Thank you so much

    I asked because an awful lot of people have recently been confused between downloading the Cloud and the perpetual versions of Lr - although I'm not automatically assuming your'e guilty of this - and can't understand why their serial no won't unlock their new software.
    If the wrong version has been installed, then it must be uninstalled and the right one downloaded.

    Assuming you know the current (mistaken) passcode, go to Settings > General > Passcode Lock.  The iPod  will ask you to enter the current passcode.  When you do, you will see a button to enter new passcode.

    I´ve contacted adobe support for cancelling a second adobe cloud I did by mistake when trying to change my billing info and I just can´t get it cancelled.
    The support people keep asking me to direct call adobe support. I´ve bought my subscription through Brazil´s Adobe Store, that doesn´t sound correct for me.
    And, there´s no place in My Adobe for direct cancelling a subscription?
    Thanks,

    UPDATE: Solved question, the second support staff was able to cancel my second (and newest) signature.

    You probably have not seen anyone reporting the exact same problem as you. All three crash reports have the same crash signature and as currently ranked 67 it is not the commonest of reasons for a crash.
    I hope you enter your email contact information when reporting crashes. I note you see this crash when using videos, others may possibly see this crash in other circumstances.
    You have already tried the obvious, attempts at a fix so it is now down to wait and see, maybe developers working on the bug will report something or fix it.
    Did you try my suggestion of installing portable ESR ?

  • Strange solution to "Something went wrong trying to install this application."

    Basically the solution was to install
    AIR
    Beta 3 then install the AIR 1.0, copy "Adobe AIR Application
    Installer.exe", "Adobe AIR Application Installer.swf", and "Adobe
    AIR.dll" from the C:\Program Files\Common Files\Adobe
    AIR\Versions\1.0 directory into the AIR beta 3 directory which I
    think was "C:\Program Files\Common Files\Adobe AIR\Versions\1.0.6".
    Then, I associated the .air file with the "airappinstaller.exe"
    executable located in the AIR beta 3 directory. Amazingly, doing
    this allowed me to install the AIR application without any
    problems.
    The problem this addresses is getting the message "Something
    went wrong trying to install this application." every time I tried
    to install an AIR application. The exact error message is below. I
    assumed that I was having problems because I had installed an AIR
    beta in the past. I'm not for sure on that though. The AIR
    installer log seemed normal. At least there were not any error
    messages that I could see. The AIR application installer log did
    not output any data for me. I followed the instructions from
    this
    blog on setting up the installer logs.
    Here is the error message:
    Adobe AIR
    Something went wrong trying to install this application.
    Please install the latest version of Adobe AIR from
    http://www.adobe.com/go/getair
    and then try again.
    OK

  • Something Went Wrong Trying to install...

    I haven't every been able to get AIR to work on my laptop
    since it was called Apollo, but I got a bunch of cool links to
    stuff at MAX that I wanted to try out, so I uninstalled the AIR
    Runtime I had, rebooted, installed AIR 1.5, and now all attempts to
    install AIR applications com back with the dreaded "Something Went
    Wrong Trying to install this application." error.
    I'm running Vista Home Premium, and I did run into a problem
    where the HKLM/Software/Classes/.air keys were locked, and after
    wrestling with the Registry permissions, I managed to clean that
    up, so the installer now seems to be creating and deleting those
    keys properly. However, I'm still getting this "Something Went
    Wrong" error.
    I've created .airappinstall.log and .airinstall.log files in
    my home directory, but the .airappinstall.log file remains empty.
    The .airinstall.log file shows a successful install of the AIR
    runtime.
    I've got several .air files that I've downloaded and saved to
    my computer, and these seem to suffer the same problems as if I
    were using the "Badge" installations online.
    If I uninstall the AIR application, and then use a Badge
    install to install both the application and the runtime, both
    successfully install. However, any subsequent application installs
    fail with the same "Something went wrong" message.

    Do you have Vista 64bit?
    Does this look like your problem?

  • I downloaded Lion from the app store on to my iMac and did not save it to a thumb before installing.  Do I have to buy it again to install on my Macbook Pro and iPad or is there another way to do that?

    I downloaded Lion from the App Store on to my iMac and did not save it to a thumb before installing.  Do I have to buy it again to install  it on my Macbook Pro and iPad,  or is there another way to do that?
    All my electronics are about a year old.   iPad is Model MB293LL (4.2.1) only wi-fi - no phone.
    MacBook Pro is  OSX 10.6.8 Build 10K549.  Also have an AT&T iPhone that I basically use as a Palm, since I changed carriers.
    Thank you for your help. 
    ps: I got an error message and it looks like this did not get posted the first time.  2nd try.

    Open the Mac App Store on your MacBook Pro
    Hold the Option key and click on “Purchases”
    Hold the Option key and click on “OS X Lion” from the purchased app list
    “Installed’ should now say “Install” which allows you to download OS X Lion.
    This assumes you are using the same Apple ID on both computers.
    Lion does not get installed on an iPad. It runs iOS.

  • I installed Windows 7 and did not realize I had to uninstall iTunes; now I've lost my database setup.

    When I installed the Windows 7 operating system, I did not know that I was supposed to Uninstall iTunes, and then reinstall my database after I installed Windows 7.  Now I have lost my iTunes database; however, I still have many .wav files on my computer, but all of the files are arranged by "Artist"; when I click on an Artist, I get the "Albums" listed for that Artist; when I click on an Album, I get the "Tracks" (.wav), preceded by the "Track Number", (space), "Track Name".
    Does anyone know if I can "Batch", search the Internet, and recreate my original "iTunes" database from the .wav files that are contained on my Music Library, External Drive "H"; and, my backup external drives "G" & "I"?  I may have additional tracks on these drives that are not included in my basic Music Library; after I include all of the .wav files on my external drives, I plan to delete all duplicate files.  My basic iTunes Program is on my Drive "C", along with my "Temporary" Audio Files; I plan to delete my Temporary Files after I recreate my Audio Library on my "H" drive.  If this is possible, could someone give me "step-by-step" instructions to do this operation.  If this is not possible, please let me know, so that I can start downloading my CD's again.
    I have approximately 3400 ".wav" files on my computer, and I feel there must be a way to re-build my Audio Library Database, without importing all of my individual CD"s again.
    Thanks for any help you can offer to accomplish my mission.
    I don't want to search my computer Drive "D", because I use this drive Exclusively for my Audio Restoration files. 

    Hi John,
    A major drawback with using wav for storage is that it doesn't carry a tag. This means that in the event of a corrupted library the only information remaining is the filename. Other data may be stored in the path but iTunes doesn't know how to get it. I understand that you need this format for your workflow with Diamond Cut, but that makes it all the more important that you backup your iTunes database on a regular basis.
    Provided that you still have the tracks in their artist and album folders and haven't let iTunes "reorganise" them you should be able to restore some useful metadata using my script TagFromFilename. The script reads the path and filename, and provided these are in the normal layout of <Path>\<Artist>\<Album>\## <Name>.<Ext> can restore Artist, Album Artist, Track Name and Track Number. If your files have a different but predicatable layout with the same information, e.g. the data is all in the filename, then I could create a suitable version of the script to get the data into iTunes. I recommend you disable both the Keep... and Copy... options in iTunes advanced preferences before adding files to the iTunes database. Ideally you also want a complete backup of your correctly structured folders in case you need to pull copies back from it.
    As stated earlier, uninstalling iTunes before the upgrade wouldn't have helped. The crucial thing before any upgrade is to backup all user data from the drive that will be wiped. Typically the iTunes database lives in C:\Users\<User>\Music\iTunes on Vista or Windows 7. The crucial file is called iTunes Library.itl. You seem fairly certain that you don't have a backup database that you could restore but an exhaustive search of your hard drive for files of the form *.itl might still be worth doing. If you find any apart from the active library we can discuss how you open them to see if they are useful.
