Installing mac os from an external hard drive

I had setup a Windows Partition and I'm wanting to completely remove it and had a single partition restored with Mac OS.  I've restored the Mac OS to an external HD which I'm booting from now as I have completely deleted the Bootcamp partition and made the Macintosh HD a single partition again.  I need to get the Mac OS on my external HD back onto the single partition that's on the Mac itself.  I'm struggling to do this and would like some steps if possible.  I've booted into the recovery utility that's on the external drive and I'm trying to image the Macintosh HD with the restore that's on my external HD.  The problem I'm having is finding where the image is that I need to copy.  I've read that I should be looking for a .DMG file but cannot locate that.  Am I going down the right path?  Please help.  Thanks

Running a SERVER on a only temporarily available disk is surely not what this OS was designed for.. Servers must be up 24/7 in order to serve their clients. Also Lion Server is only an app, running on top of normal Lion, so the App must be actively running all the time.
Disk Permissions in Lion ( client or server ) are not that different to Snow, but Lion mounts all partitions as read-only on the Root level, so that write is only taking part in the /Users and /Library directories. ( /System only if validated installers are launched with Admin rights ) .

  • Installing Mac OS on an external hard drive

    I've had an 80GB Mac Mini for about a year and I absolutely love it. Yet, because I use it so much, during this short time I have quickly maxed out the storage with a large amount of photo and music files. Can I install my current Mac OS on an external hard drive where I will have 4 or 5 times the hard drive space for photos and music and still retain the option of booting to that or my Mini? I had a support tech tell me this was possible, but at the time I wasn't ready to do so.
    Another option would be to store music and photos on the external hard drive such that iTunes and iPhoto will navigate to folders located on this drive instead of the internal Mini hard drive. I'm sure this would be the best option, but I don't know how to do either of the two.
    Would greatly appreciate any assistance and advice. Thanks!

    Since I've gone both routes, I figured I'd chime in. Shortly after buying my mini bought an external firewire (don't even think about USB no matter what the sales drone might tell you) and cloned my system to it. I then created a nicely sized BootCamp partition and used the external for Mac work and the internal for PC work. I kept a small Mac partition on the internal removing everything from the OS and Disk Utilities - basically a fast diagnostic disk. That was a great way to work and a side benefit is that the 7200 RPM external FW drive booted up a bit faster. Disk space taken up? Well, yeah, but how big is an external drive? Besides, there are external drives (and do it yourself cases) made especially for the mini so you can stack them.
    This summer the internal drive started clicking - not a good sign - and so I cloned the PC partition and bought a new internal drive. I've had a fair amount of experience opening minis but I make up at least one new curse every time I do There are a couple mini fan wbesites around so check them out to find out what drives are mini friendly today, check out the instructions, and see if the job is for you. It isn't brain surgery but it is more involved than putting a bandaid on a skinned knee.

  • Installing PhotoShop CS from an External Hard Drive to PC Vista

    My Dell laptop crashed about a year ago, and I was able to have the hard drive backed up to an external. I now need my PhotoShop CS which is on the external hard drive. I need to know how to install PhotoShop, and others in the creative suite, from the external drive. I am having a problem figuring out which files need to be installed first, i.e. .exe and .dll files.
    The hard drive is an iMicro 3.5" SATA and IDE HDD
    I am currently running Windows Vista, Gateway Notebook
    **I can not find the original Creative Suite cds; I think they may have been "accidentally" thrown away by someone other than myself. Long story.
    Any help is greatly appreciated!
    Thanks!

    >story.
    Uah... Who would be so obviously plain stupid? I mean, one can throw away the boxes, manuals and gift wrap, but by all means keep the media in a safe place. *yikes* Anyway, as the others said - without the original install CDs that is a no go and unless the missing disc turns up magically, an upgrade to CS4 is the only way to get going (and that's assuming you know your serials and have registered them).

  • Install Windows 7 FROM an external hard drive

    Hello everyone,
    I was just wondering if it is possible too install windows 7 using boot camp from a 250GB external hard drive. I have a bootable image of windows 7 on my Macbook Pro, but want to know if its possible to install before I try.

    Hi,
    The simple answer is "No".
    Have a look at this post ((http://discussions.apple.com/thread.jspa?messageID=12308829&#12308829) for a short answer.
    Best bet in getting started with bootcamp is first to read through the "Boot Camp Installation & Setup Guide" (http://manuals.info.apple.com/enUS/Boot_Camp_Install-Setup10.6.pdf)
    Will probably want to look / post on the "Apple Discussions: Category : Boot Camp" (http://discussions.apple.com/category.jspa?categoryID=237) if you have further questions - more for bootcamp.
    Hope this helps.

    For what the Apple Store's charge you can buy almost buy a new computer.
    Just for giggles I brought my old laptop in for a drive upgrade and asked, they wanted $600 for a drive that only cost $120 at the time and it was a slow 5,400 RPM drive. The new Mac's of a similar make were going for $1000.
    I did the drive replacement myself, got a faster drive of better quality for $300 instead.
    Then another time I asked for a RAM upgrade from 4GB to 8GB, they wanted to charge $400 + $35 for the labor.
    The same RAM is on Crucial.com for $90 and all I need is a 00 micro phillips screwdriver.
    So you see what's going on here.
    I think what you should do, if your out of warranty/AppleCare, is to call up the local PC tech guy who also does Mac's and have them fix you right up.
    They can offer more personalized care which you need. Clone your old drive to the new and everything.
    With Apple they are overworked at the Genius Bar and just place roadblocks so you buy a new machine instead.
    For instance, all new iMac's now have proprietary drive software installed on the hard drives for heat monitoring. So now the only choice a user has is to bring their iMac into a Apple Store for a very expensive drive upgrade, which a person then decides the money is better spent buying a new machine.

  • Can I re-install Adobe Creative Suite from an external hard drive?

    After an appointment in the Genius Bar I have decided to have my mac's hard drive completely wiped. I had installed Mavericks and it caused a lot of my Adobe programs to stop working probably, the girl in the mac store said this was because the Adobe Master Collection CS4 is incompatible with Mavericks. So I'm having to take my Mac in to be completely wiped so that Lion can be reinstalled. I have ran time machine on an external hard drive to back up all my files, including my Adobe master collection. When I get back Mac back, can I reinstall my Adobe programs just from my external hard drive? If so, how do I do this?

    You can try with migration assistant.. but I think you would be much better doing install from original disks. You can recover your working files etc..
    Alot will depend on what you have done with Time Machine since you upgraded to Mavericks. If you did not do any TM backups you could have simply restored the computer from TM.

  • I transferred data from my external hard drive to my restored Mac Book Pro via migration assistant and now my external hard drive in time capsule has red minus signs. How do I get rid of that without getting rid of any of my data?

    I used Migration Assistant to transfer my data from my external hard drive via Time Capsule to my restored Mac Book Pro. When I now go into Time Capsule I there are red minus signs in the corner of all the folders that are contained in my back up. How do I get rid of this and access my previous back-ups?

    Select the drive and Finder > Get info and at the bottom "ignore permissions on this volume"
    You can copy the files, but the ownership on the files still belongs to the other user account, once your done copying, then perform a #6 Reset Users Permissions and that will set all the ownership to that account.
    ..Step by Step to fix your Mac
    Another method is to copy the entire folder, then change it's permissions.

    I'm attempting to migrate files, address book, maile, etc to my new Mac Mini using an external hard drive and Migration assistant.  I followed the instructions on using Migration Assistant to do this but Migration Assistant is not seeing the external drive, which is displayed on my desktop

    I've been chasing this problem all afternoon. I had to reformat my internal drive on my MBP and reinstall Mountain Lion   Start up assistant wouldn't see my extrnal drive with the Time Machine files on it.  After many tries, I skipped the restore there and let the system boot.  I could see my external drive from Finder and the files looked OK.  I was told to use Migration Assistant and it had the same problem.
    I saw a hint on one of these posts that the icon that you see and is label Macintosh HD is actually your backup disk and it is telling you that it has a copy of your internal Macintosh HD.  I went ahead and told it to continue and it started to restore my apps, settings, and documents.  It's been going for a couple of hours, and is close to being done.  I expect to see my old system restored when it is finished.
    Wish that Apple would put some type of note that it is seeing the backup. That is most confusing and seems to be a problem for lots of users.
    It's been a month or so since your post  Did your get it to work?

  • I was trying to back up my mac by using my external hard drive.  Without realizing it, time machine erased all my backups from my other computers.  Is there any way to recover these files?  I can't even get the external hard  drive to work on my pc.

    I was trying to use my external hard drive to back up my mac computer.  It had files on it from my pc computer.  Time machine erased all my existing files. (I thought it was only going to erase the duplicate files and rewrite them).  Is there anyway to recover these files from my external hard drive.  My mac has renamed the hard drive time maching and it will no longer show up on my pc.  What can I do?

    Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
    In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

  • Can i show and play music from my external hard drive in iTunes without adding it to my Mac hard drive?

    I have more music than I can keep on my Macbook hard drive by over 200GB. I'm hoping to be able to show and play all music from my external hard drive in iTunes without having to add any of it to my Macbook Hard Drive

    Hello B3NN13,
    If you would like to add the music from your external hard drive to iTunes without copying it to the iTunes Library on your internal hard drive, you may find the following article helpful:
    Add files to your library without adding them to your iTunes folder
    When you add an item already on your computer to your iTunes library, iTunes places a copy of the file in your iTunes folder. The original file remains in its current location.
    You can change this setting so that files are added to your iTunes library without being added to the iTunes folder. You might want to do this, for example, if you prefer to store video files on an external disk but still want to view them in iTunes.
    Choose iTunes > Preferences, and click Advanced.
    Deselect the checkbox next to “Copy files to iTunes Media folder when adding to library.”
    From now on, when you drag a file to your library or choose File > Add to Library, the item appears in iTunes, but the actual file isn’t copied or moved.
    Tip: You can temporarily reverse this setting by holding down the Option key while you drag files to the iTunes window.

  • How do you transfer info from an external hard drive from a PC to a Mac

    How do you transfer info from a external hard drive from a pc to a imac?

    Expanding on what Niel said, a Mac can mount and read just about any hard drive from a Windows system. It can't write to an NTFS-formatted drive without third-party drivers, but it can read them. So as Niel indicated, you should be able to just connect the drive to your Mac and drag-copy over whatever you want. If you want to save things from the Mac to that drive, then it will need to be formatted either as FAT32 or exFAT, or if it's NFTS you'll again need drivers.
    Regards.

    If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?

    To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
    If the pictures are precious you should have at least two copies, and ideally another copy kept off site,

    How do I input songs from my external hard drive, taken from a PC, to a Mac?

    Just a few song tracks, or your whole library?  If just a few tracks, drag them from the drive to the open iTunes library window or playlist window.  If your whole library drag the whole iTunes folder to your computer.  Hold down the option key while starting and guide it to the library.itl file in that folder.  If you need to merge libraries post back because that's a much longer post.
