Clean install of ML - what will happen?

I have made a bootable USB drive with Mountain Lion installer.
I am prepared to make a clean install of ML on my drive (since it has become slow and glitchy).
I have a clone of my Mac drive, and have made a dmg of my windows drive and put them both on a bootable external hard drive.
Now I am ready to proceed in formatting my mac drive but I have to questions (which no one after hours of googling seem to be able to answer):
Two questions.
1. What will happen to my Boot camp partition after a clean install of Mac OS X? Will I still be able to boot windows normally?
2. What happens to programs that requires license to install, for example Office 2011, Photoshop CS5 etc? Will they allow me to restore it from TimeMachine backup or my clone or do I need new licenses?
From what I've read so far... The least problems is if I keep my username exactly as it is, manually copying files and folders from the clone drive to the new installation of ML. Downloading fresh programs from the internet. But still, the licensed ones will have files spread all over and can't easily be copied right? And also, will my computer be able to instantly recognize the boot camp partition and load it normally?

Your question 1.
Do not manually copy any files... particularly applications. There is so much that has to be moved over, it is impossible to know where these files are. When you reinstall the OS you will be asked if you want to transfer stuff over. Take that route, and save yourself an impossible task.
The good news is that when you do it that way the license info should also be transferred. In any case you do not need NEW licenses. At worst you will have to do a one-time re-enter of the ones you have.
Your question 2.
I believe, but let's hope some one more knowledgeable than I will confirm, the Bootcamp partition does not have to be erased during a clean install.

  • What will happen to iPod 5G's info when I do a fresh Windows install?

    Title basically says it all. I've been using my iPod Video as a storage device as well as for music, and I'm going to do a clean install of Windows XP in the near future-my CD/DVD drive has somehow failed to respond (code 41), so reinstalling Windows to factory settings should do the trick. Only problem I can foresee is what will happen to all the data on my iPod when I reinstall the CD software for iTunes and my iPod drivers-will all the data on my iPod disappear when I reconnect it to my laptop for the first time?
    Just wondering if anyone's done this before, as I'll assume it's a typical topic.

    When the iPod is connected to the PC after reinstalling Windows, a message will appear asking you if you want to change the computer the iPod is associated with will appear if iTunes is installed; pressing Erase & Sync on this dialog box will delete all content on the iPod that was synced from iTunes. Content copied to the iPod outside of iTunes will not be erased by iTunes unless you explicitly restore the iPod.

  • What will happen if I install Lion on my macbook pro core duo??

    What will happen if I install Lion on my macbook pro core duo? I have one of the first Intel MacBook Pro's with a Core Duo processer, I'm having hard drive problems so want to format it and re-install my OS. I can't find my Snow Leopard disk so the easiest thing to do would be to download Lion but I have been told that my MacBook needs to have a Core 2 Duo processer so I just wondered if anyone else has tried Lion on a MacBook like mine??

    Nothing.
    Lion will not run on a core duo, it needs a core 2 duo as a minimum
    see Technical Specifications
    Also you will need SL running to access the App Store to download Lion. So In a number of ways this won;t work.

  • What will happen when I install Leopard?

    So when leopard comes out in a few weeks and I install it, what will happen to all the files and apps on my computer. Will they be gone? Will I have to redo everything?
    This is my first transition on a new OS X. I switched right aftr Tiger came out. What is going to happen?

    Fair comment!
    If you want the full nine yards:
    There are no guarantees, but following this procedure when installing updates and upgrades on your Mac will go a long way towards avoiding unpleasant after effects and ‘post-update stress disorder’.
    It is also worth noting that it is an extreme rarity for updates to cause upsets to your system, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
    So before you do anything else:
    If you can, make a full backup first.
    Turn off sleep mode for both screen and hard disk.
    1. Repair Permissions (in Disk Utility)
    2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
    At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
    3. Download the correct version of the COMBO update from the Apple download site. If your car runs on gasoline you would not want to fill the tank with diesel, so don’t try to install the PPC updater on an Intel Mac!
    If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
    Using the Combo updater ensures that all system files changed since the original 10.4.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.4.9 to 10.4.10. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
    Now proceed as follows:
    4. Close all applications.
    5. Unplug all peripherals except your keyboard and mouse.
    6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
    7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
    8. Once your Mac is awake, repair permissions again, and you should be good to go!
    If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
    9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them 10.4.10. compliant. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 3.
    N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.

  • What will happen if I try to install XP SP1 under Boot Camp?

    Hi all. I'm new to the discussion and to the Mac world.
    Before I go buy XP sp2 or sp3; does anyone know what will happen (nothing will work or limited functionality) if I try to install XP SP1?
    Don't want to try it if I'm going to "break" something...
    thanks in advance.

    Macbook_Juice:
    Please do not bother to install Windows XP with Service Pack 1. It will not work and the installation will more than likely not finish. Save yourself the headache and get the right copy of Windows which work with Boot Camp.

  • What will happen if i install lollipop from another region ?

    Hello guys,
    I have Z2 and it seems that sony has released lollipop for nordic regions (http://forum.xda-developers.com/xperia-z2/general/lollipop-690-z2-z3-z3c-t3056997)
    but mine is UK version. (not carrier locked or something)
    I wana know if its safe to install this version on my phone. And What will happen if i install it ?

    There are different model number and these are what let us know where in the world or area you are and what bands or networks frequency's your phone will work on so Flashing a EU firmware onto a US device may make your phone stop working ie:receiving a network signal you may also notice that a Z3 for example has different model numbers like D6603, D6643, D6653 and D6616 so flashing a D6653 firmware onto a D6603 could make your device what's known as a brick

  • What will happen if i install this printer software update

    RE: HP software update 2.11
    i have an hp printer (of wich i am getting a replacement when i can)
    i used to have a pc and the software was a nightmare it always wanted to update
    and i dont trust or like hp software
    will this update install an hp software program
    i like the mac printer software i use it to scan and print just fine without the hp software
    maybe a wierd question .. i might be a little scard from to much windows exposer haha

    I don't blame you for your concern, but what will happen is probably nothing. No apps are installed, just new or updated drivers.
    If you click the link associated with that update you will see a comprehensive list of all the updated HP drivers. The update probably delivers drivers for newer HP printers, leaving the older ones unaffected. If your existing printer is working you can just ignore the update.
    I'm still using a LaserJet that I bought in 1993; the update didn't change anything.
    If you are in the market for a new printer I recommend researching other manufacturers.

  • What will happen if i dont back my mac up before installing os s yosmite beta

    what will happen to my mac if i dont back it up before installing os x yosmite ?

    We have no idea what might happen; it is not good to run beta software on a regular production machine. We also cannot help with any problem you might encounter - you will need to contact Apple and/or provide them feedback due to the confidentiality agreement (you're not allowed to discuss the beta anywhere and we're not allowed to discuss it).
    So, if you want to install it, do so on an external drive or partition so your regular system is safe.

    What about the notification looks like it will switch over to the creative cloud?  I'd avoid it until you get a good answer to your question.

  • Uninstalled then re-installed iTunes... What will happen to my synced iPod?

    My computer had a virus and had to be totally re-done, and in the process it removed iTunes and some of my music files.
    My iPod was synced to one of the playlists on iTunes.
    If I reinstall iTunes, then connect my iPod to the computer, what will happen?
    Will it try to sync or not?
    If it does, how do I prevent it from doing that?
    And if it doesn't, will it be possible to edit the songs on it?

    If you lost your itunes library file (itunes library.itl in your itunes folder) when you reinstall itunes you'll probably need to reimport all your music and recreate your playlists; it will be like you just installed itunes for the first time. When you first connect your ipod itunes will ask you first if you want to sync that ipod, so you could always say 'no' and set it up to sync later.
    I think when you try to sync your ipod itunes will try to remove the music files that are currently on your ipod that aren't in the itunes library - I think it will ask first and there might be an option to not delete those songs - sorry I can't remember right now. It might just delete them without asking. If you really want to avoid this there is an option to manually manage the music on your ipod but it's definitely more time-consuming.
    If you lost music files from your computer that are still on your ipod, you can try this program. I had a friend who got an old ipod from his brother and used this to copy the songs onto his computer - it will only do a certain number of songs, so only do the ones that you might have lost. If you want to try this you should do it before you reinstall itunes, because when you connect the ipod itunes will automatically come up if it's installed on the computer.

  • What will happen with my installed softwares?

    Hi I am using MacBook Pro with C2D and having latest version of SL. But I have installed lots of software useful for my business including virtual machine and I am using Windows 7 ultimate on it. So I am wondering what will happen if I upgrade this to Lion? Do I need to install everything again or it will be as it is like on my snow leopard?

    I don't know about VMware, but I can tell you that when I opened Windows XP the first time in Parallels after upgrading to Lion, I had to re-setup the virtual machine. Other than this, no problems. CS3 and older WILL NOT run in Lion, but CS4 and newer run without problems.
    Go to About this Mac > applications, and here you can see which of your applications are PowerPC, thus not compatible with Lion.
    Cheers

  • What will happen if I don't install foxfire 4?

    after reading through the many changes you want to provide. as a senior citzen and not wanting change I want to know what will happen to the platform i'm used to?

    You can keep on using Firefox 3.6. It is likely to be supported with security updates for quite a few more months.
    As you have Windows XP, by default Firefox 4 will look very similar to Firefox 3.6, it will use the old user interface unless you change it to use the new interface.

  • Rescue and Recovery with only one partition, what will happen? Thanks!

    Hello, everyone! This is my question: If I do a clean installing of Windows 7 with only one partition(the C and I install the Rescue and Recovery tool, when I make a backup of the system by using the Rescue and Recovery then the backup file will be stored in the partition C:. So when I restore the system with the backup file later, if I can succeed and what will happen? Thanks.
    Solved!
    Go to Solution.

    Backups and restores will still work.  The risk is if something happens to your hard drive, then you would lose the backups as well.  For this reason it's a much better idea to store your backups somewhere else, such as USB hard drive or network.

    No reason to be embarassed. You are not alone.
    You will need an external drive. If you have a Time Machine drive without enough disk space you can create the clone there however it's advised that you keep your Time Machine and clone on separate drives. If the drive dies you loose both types of backup.
    Download and install the clone software. Everyone has their favorite. These are the two most common applications used. I prefer SuperDuper because of it's simplicity in setting up. It's also free for the first clone where with CCC you have to give a Credit Card then cancel if you do not want to keep.
    SuperDuper! http://www.shirt-pocket.com/

    Select your drive in the To popup. Click on Copy Now. That's it.
    Yes, it really is that simple....

    Highly unlikely that it says any such thing.
    Try telling us exactly what version of iTunes is installed and what if any messages appears when trying to update it.
    What Operating System is the computer running?
