Mountain Lion re-install has migration assistant options greyed out. How do I choose only data I want?

I ran out of space on my Mac Mini so I bought the iFixit kit and added a second drive. This resulted in me putting a 60GB SSD system drive and a faster 7200 RPM 500GB data drive in the mini. I removed the original 500GB drive and placed it in an external enclosure.
After installing Mountain Lion I ran migration assistant. It shows all the data from the external drive, but everything is checked and it will only migrate to my 60GB OS drive. Of course this won't work.
I made a link to /Users to my second internal data drive but migration assistant still shows a -486.34GB of space needed.
So, instead of taking a week to upgrade my App Store purchases and install and configure everything (Mountian Lione Server, Xcode, Microsoft Office, Parallels...) how can I get migration assistant to allow me to just choose specific items to migrate?
As a side note, how can I make Mac OS X Mountain Lion use the second internal drive for User accounts *AND* recognize it properly? My link works but I'm early into this and would rather do it 'right' now then live with frankenmac later.
Thank you,
-Tim

Well, maybe I posted to the wrong forum...
I went in to speak with a mac genius too. All I got was, "In all the years I've worked on Macs, I've never seen the migration assistant with greyed out options." Ok. I guess I have more experience, I've seen it. They then suggested I run check permissions on the drive and buy Disk Warrior for $100. Sorry guys, the drive is fine. My TM backups are fine. It's not that.
I went ahead and bought a 1 TB drive. Even then, the migration assistant choices were greyed out. I went ahead and created a Fusion drive to take advantage of the SSD (the 1TB is only 5400 RPM). The directions can be found here. I then just ignored the greyed out options and brought *all* the data over to the 1.1TB drive. Everything works fine.
I'm bummed about not getting the apps and O/S pinned to the SSD but I figure if anything is getting used a lot, its where it needs to be.

Upgrading to mountain lion and install has stop

I have started the upgrade to mountain lion and it has downloaded and started to install
It had a message that the machine would restarted automatically during the install
When it tried to do that it has now stopped at at blank white display
What should I do?

Hi, were you upgrading from 10.6 or 10.7?
"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 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, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
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.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Dual boot, Mountain Lion and Mavericks and Migration Assistant

Hi all,
I have a Macbook Pro Retina which cam with Mountain Lion installed, and I want to upgrade to Mavericks. However, I have a need to run some apps in Mountain Lion, as official support for those apps will not go past 10.8.5 (Avid's Pro Tools 10) and I need to be able to open archived projects.
I also wish to clean install both operating systems fresh, and do a stripped ML partition, with bare bones essentials, on the smallest partion possible. Mavericks will be the main system, and ML won't host user data, only the legacy apps. I am fine with erasing my 500GB SSD.
My current process is to install ML from the recovery partition, and use disk utility to partition before I do, then install Mavericks from a bootable USB (already made).
So my questions are these:
For ML:
1. What size partition is the minimum necessary to install ML, plus the apps and run without hitch? The legacy apps will take maybe 4GB.I want this as small as possible.
2. When I do a fresh install of ML, what apps can safely be deleted without affecting the system?
For Mavericks:
When migrating my old user account to Mavericks, I don't wish to migrate the apps, just the user settings and the data. I will make an entire backup of the user directory on a separate drive before I start this process, as well as a Time Machine backup. I then plan to migrate the account settings and data, but manually reinstall the extra apps. The reason for this is I have a lot of third party apps, and some are trials I decided to uninstall, and they all leave junk behind.
3. If I import the user account settings and data only, what cruft or orphaned files should I be aware of?
4. Are there options to cherry pick the settings that are migrated?
5. If I manually copy, for example, the mail folder, iCal or messages folder in my user library, and place it into the appropriate user folder in the new account in a worst case scenario, will there be any drama I should be aware of?
Lastly, a question of Apple ID's/iCloud:
6. Before doing this process, should I deauthorise my iTunes account, or will that be fine when migrated anyway?
7. What will happen with my iPhone when I sync to a fresh install on mavericks, will it attempt to wipe my iPhone, or is that part of the user data that is migrated?
Thank you for your time and patience reading this!

ML
1. I'd go with at least 40 because you need some extra disk space for the computer to work properly. You can install that one partition, load it, and see how much disk space is used and adjust as required. Also boot from it and make sure it runs okay.
2. Everything but the Apple applications, which you probably won't be able to delete.
Mavericks
Almost all applications are stored in the hard drive level Applications folder. Check your user applications folder and if there are no applications, just copy the entire user folder.
3. Hard to answer. In theory, none.
4/5. They may not work due to differences between 10.8 and 10.9. You might want to consider using Setup Assistant and restore from Time Machine. Then delete the stuff you don't want.
6. Shouldn't matter - same computer. I have 2 partitions and both are authorized for iTunes and the App Store.
7. If you restore from Time Machine, you should be okay.

OS X Lion Disk Utility - "Erase Free Space" option greyed out

After installing OS X Lion on my iMac, the option to Erase Free Space from Disk Utility is greyed out and can't be selected. Is anyone else experiencing this problem, and if so, does anyone know of a possible solution?

I'd not noticed that, and am not on Lion at the moment.
But it's not a good idea to do that on the volume you're running from. OSX collects all the empty space into a huge folder (so the free space on the disk goes to zero), then writes zeros to it, and releases it as it does so. That will take a very long time (241 GBs, in your case). If something goes wrong, or you cancel it, it can be rather difficult to get it to release the space.
It does not gain you any space; all it does is prevent the leftover data from files you've deleted and emptied the trash from being recovered.
If you really need to do it, use the Recovery HD. See Using the Recovery HD.

I have a MacBook Pro bought in dec 2009. Currently has mountain lion osx installed. Worked like a dream until today. Randomly froze, so I restarted it. To find I got a grey screen. It wouldn't start. Also note my DVD drive doesn't work, but mountain lion was installed via App Store anyway.
So here's what I done so far:
tried resetting PRAM - No success
Done disk utility. Disk verified with no errors. I even re formatted disk. - no success starting.
Tried re installing mountain lion via download . It froze halfway installing -no success.
Tried backing up a time machine backup from my USB hard drive. It froze at 1% - no success
Tried booting from safe mode - no success
Tried the command line boot - no success.
Please someone help!

Sounds like the hard dre has left the building, Died, in the Sh*tter, Gone to the hard drive resting place in the sky.
Buy a new drive connect it to the system with a SATA to USB adapter and see if you can install Mt Lion on that drive connected externally. If you can then the drive inside your system has failed.
Oh Wait!!!! You have the 2009 model. They are known for bad drive to logic board cables. So it may not be the drive itself but the cable going from the drive to the logic board. Do the same as above then if the system runs OK with the new drive connected externally install it in the system and see if it boots. If it does you are good to go. If it doesn't then it is more then likely the cable that hs failed.
I would suggest you also SAVE a copy of that download of Mt Lion and create a USB install drive from it using Lion Disk Maker, once you get your system up and running.

I have tried to install Mountain Lion but it has failed to install properly

I have tried to install mountain lion but it has failed to install

If you open Finder and open your Applications folder list, under the alphabetically listed "I"'s you should see an application called "Install OS X Mountain Lion.app", if it downloaded OK. This is the package that you double click on to begin installation of Mountain Lion. Have you already done this?
Hope this helps

Since I installed Mountain Lion, my iMac has shut down after 15-20 minutes. I have adjusted screen saver, shut down time, and sleep after. Nothing seems to help, any ideas?

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...

It is the 5 second timing that initiates the reset.

Can Mountain Lion be installed under own ID over previous owners?

I bought a barely used Mac Book Pro Retina in November 2013. 512 GB 16 GB Ram model samsung screen made in March 2013. I called Apple and they helped me get everything over into my name except the Mountain Lion OS. The previous owners Admin. account was also deleted after I added mine.They said if I wanted to upgrade to Maverick that would be in my name. The problem is if I wanted to revert back would it accept the previous owner's or would my licensed version have to be on first? I do not plan yet to update but need to know first.
I went to Apple.com last week and purchased my own license for OS Mountain Lion. I followed the emailed instructions and downloaded into my Applications. I then backed-up my computer to an external Toshiba Canvio Slim II external drive for MAC. Easy drive to back-up.I also printed the emails and sent over to another computer for safe keeping.
I left my licensed version of Mountain Lion OS in Applications until I want to install it.
My question is do I install over the previous owner's Mountain Lion and will it then it will show up in my name only? Or do I have to reset the entire computer and erase Mountain Lion and install my Licensed Mountain Lion? The only thing I see of the previous owners is the iPhoto update won't update but that may be because mavericks now on it to do so. I deleted iMovie and Garageband but couldn't purchase in my name as I didn't have Maverick OS.
I have had no issues with downloading from iTunes or Mac App Store or anything else in my name and or updating since I had Apple help me.
I appreciate all the great feedback on this forum.
Thank you.

No, it can't. You must repartition the drive in order to install your owned version.
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

How do you erase mountain lion to install snow leopard?

Hi, My mother now has a new to her late 09 mini that originally shipped with snow leopard. When she bought it it came with mountain lion preinstalled from a private seller. We were thinking that to be on the safe side that it might be better to erase and install what's on it just to be sure it is secure. I tried to erase and install snow leopard from a disk but it says that the installer is not compatible with this version of osx(mountain lion). Question: How do I erase mountain lion and install snow leopard?
I've read here that there is possibly a built in recovery disk that I can use to erase and reinstall mountain lion. Q: Is there a built in recovery disk available in my situation? and if so should I use it or be even safer by installing snow leopard instead?
Thank you,

I think I found the answer (from sl install disk use disk utility to erase then install sl). Thanks for looking.

Does mountain lion support install from a RAID drive?

does mountain lion support install from a RAID drive?

Apple does not support the 3rd party drives. To enable it (without installing another software package), you can visit the website:
http://digitaldj.net/2011/07/21/trim-enabler-for-lion/
I ran the series of commands on my Mac Pro and it did enable TRIM.
the webpage even has a backup/back-out procedure.
Without TRIM, my computer was running extremely slowly. After enabling TRIM, my computer ran substancially faster.

If you can download the ML installer you can make a bootable install media by using:
http://liondiskmaker.com/
If your Mini came with ML you can also boot to Internet Recovery
OS X: About OS X Recovery
and it will install ML. Make sure you boot to Internet Recovery and not the Recovery Partition. If to the partition you will only get Mavericks.

How long does mountain lion take to download and where does it say how much it has left mine just says downloading ?

how long does mountain lion take to download and where does it say how much it has left mine just says downloading ?

It's totally dependent on your broadband speed.
It took me about 45 minutes to download, but I have a reasonably fast connection.
It will often say in the purchased pane of the Mac App Store how much longer it will take.
