Re-installing Mountain Lion to iMac with Fusion Drive

Hi I have heard all the horror stories from people regarding installing the new Maverick. I was hoping to try it, but wanted to play it safe by first learning how to recover back the original state of my Mac OS.
I have a Mac OS X ver 10.8.5
Processor 3.4Ghz Core i7
Memory 16GB 1600Mhz DDR3
Please advise as to how to install a clean Maverick OS.
I will then re-install all the programs one by one.
But if none of my software work well, I will want to go back to my original OS.
I do not have a Moutain Lion CD so if I wanted to reinstall original OS how do I go about it?
I have also noticed that the cursor problem has never been quite solved. Still occassionaly dissappears.

I read that I cannot use the Recovery Disk Assistant v1.0 to create an external recoevery disk for a fusion drive is that true?
Can you please point out or explain a bit more on how this internet recovery system work? What do I need? Just an internet connection? Or do I have to have some cloudbased recovery system which need to be set up? Do I need my password or Apple ID?
Sorry for my ignorance.

You may have a folder named Backups.backupdb at the root level of your startup disk. You cannot find it with Spotlight. Just navigate to your startup disk (usually named "Macintosh HD") and drag Backups.backupdb to the Trash.
Is your startup disk partitioned? If so this may be applicable:

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...
You are now in a perfect position to do a

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

Can I install Mountain Lion on a different hard drive when it's already installed on one hard drive?

I have a Mac Pro with two 2TB hard drives installed, one I use for storage, and one as my startup disk (also store things on there as well). I just installed two new 2TB drives and have set up a RAID 0 with them. I want to use the RAID drive as my start up disk, but I'm not sure if I can install Mountain Lion on the new RAID drive while it is still on the original start up drive. I also don't want to lose or erase any information from my current start up drive. Can anyone offer me guidance??

Firstly, you need to partition and format the SSD. You need to be able to boot the computer from another drive that has a bootable OS X system installed or a Snow Leopard DVD installer that works on the computer.
Install Lion/Mountain Lion on a New HDD/SDD
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 external 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: Select Reinstall Lion/Mountain Lion 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.

Installing Mountain Lion onto an external hard Drive

Hi
I am running snow Leoprd and what to keep this as my main OS on my internal HD due to work, I want to install Mountain Lion onto an external Hard Drive and boot and run from an external HD as opposed to my internal
I will be likely to be using a thunderbolt connection for the external HD
Has anyone had any experience with this and any tip or faults?
I will be using Logic mainly]

Works just like installing on an internal drive. Just be sure to choose the correct target before clicking on the Install button.
If you have sufficient space on your internal hard drive you could also make a partition on it in which to install Mountain Lion. This will be faster and more convenient that an external drive.

I erased my HD. Now I can't instal mountain lion from my bootable flash drive, and keep getting "installation error. Try again."

I bought mountain lion, made a bootable flash drive.
I booted from it and it went to upgrading right away!
So I stopped it and went to my former recovery partition I erased my HD because I wanted a clean start.
Now I can't instal mountain lion from the bootable flash drive, and keep getting "installation error. Try again."
and there is no 4 choices window.
I don't know what to do.

How did you create the USB install thumb drive? If it was with Disk Utility I have run into this problem and have since used THIS program to make the USB install drive.
As to your problem you only have one option and that is to Reinstall the Original OS X version that came on your computer or if you still have the Lion Recovery Partition use that to reinstall Lion. Or if you system came with Lion and you have No Lion Recovery HD Partition you can boot the system from over the internet and Reinstall Lion.
At startup hold down the Command+Option+r keys until you saa a spinning Globe in the center of the screen. Once that loads Repartition the drive as One partition and then reinstall Lion.

How can I install Mountain Lion in a VMware fusion, if it came with my macbook pro, and not purchased through the app store?

I have Mountain Lion on my Macbook Pro with Retina but I want to install Mountain Lion in a VM for application testing. I try to install it from the recovery partition but it states that when I put in my apple ID, it states that it was not purchased through the App Store. My OS came with my Macbook. Is there anything that I can do to get it to install in a VM?
Thanks

After installing Mountain Lion, my iMac gets VERY hot!

I installed Mountain Lion yesterday onto my mid-2010 21.5" iMac. Today, while running it normally, it got so very hot that I couldn't even touch the aluminum back. The heat could be felt through the glass on the screen.
The fans could be heard, but didn't seem to be going overtly fast. CPU, memory, and disk usage all appeared normal.
I had Firefox, mail, Excel, and 1Password open at the time; certainly the apps weren't taxing the system.
Anyone else have this problem? Any suggestions?
Thanks!

Although the specs for Mountain Lion say it will run on 2 GB of ram, you really need 4 GB to run well. You can look at Launchpad > Utilities > Activity Monitor to see the memory usage with software open. If there are a lot of page swaps, in and out, you need more memory.
Good sources are OWC and Crucial for guaranteed compatible memory.

How do I re-install Mountain Lion on a new hard drive (replacement)?

I have an older iMac 24" (2007) that has been up-graded to Mountain lion. I want to replace my hard drive with a bigger one (has 500Gb). How can I re-install Mountain Lion on my new drive? I have Time Machine on this machine.

Install 10.6 and 10.8 onto the new drive exactly how you did it on the old drive, except that you won't need to pay to redownload 10.8. Alternatively, if you kept a copy of the 10.8 installer, you can just rerun it.

Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
   2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this entire command line after the prompt in the Terminal's window:
     sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume
     /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.

How do I install Mountain Lion AND format the hard drive?

I want to do a completely clean install of Mountain Lion.
I had Snow Leopard installed, upgraded to Mountain Lion (by buying it from the App Store) but how do I tell it to format the drive and then install Mountain Lion?

Snow Leopard would have needed to be installed on a properly formatted drive, so I don't understand why you would need to format it again to that same format.

Unable to install mountain lion on iMac

Hello
I bought mountain lion and installed it with no problems on my macbook pro. After that i wanted to install it on my iMac(intel) too, but here i fail repeatedly.
Mountain Lion gets downloaded, installation dialog appears, everything seems normal except for duration: Once the installation starts it says "Remaining time 3 minutes" and thats it, after three minutes the whole process ends, no reboot, no error message, no nothing.
On my MBPro it took about 50 minutes (estimated 30 minutes and then another 20 minutes) - but the installation succeeded.
On my iMac it says from the beginning that it will take only 3 minutes.
I disabled time maschine, no user except admin user is logged in.
What can i do?
iMac was bought about last summer, i am within my 1 year warranty - so my iMac should not be too old.
Regards

Could be many things, we should start with this...
"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."
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 10.7 or more, reboot holding CMD+r down to boot from the Restore Partition, use Disk Utility there to repair the Disk, reinstall may be needed if errors were found.

Help with installing OSX Lion on iMac with broken display

Hi,
Having some trouble installing OSX Lion on my 5 year old iMac which has a broken display.
The display has been dead for a couple of years now and I've been using an external monitor without any problems. Today I decided to upgrade to Lion - I downloaded the installer from the App Store and started the install which rebooted the machine. After reboot I'm presented with a grey 'thatched' background image on the external display and nothing else, no menu bar, installation menu etc.
I presume the internal display is showing the menu I need but I can't see it as that screen is broken. Is there a way to turn on mirroring during the install process so I can use my external display? I've tried various shortcuts held down during startup - OPTION-F14, CMD-F1, CMD-F2 - but none have worked.
If this isn't possible, is there a way to abort the Lion install process and go back to using my Snow Leopard install? Whenever I boot the machine I am taken to the OS X Lion installer and don't know how to get back to my Snow Leopard install. I tried holding down OPTION key on startup to choose the list of available OS installs, but again, the internal display is being used so I can't see what to do.
Thanks in advance for any help.

Genius idea, thank you. Was able to step through the install procedure using voiceover and the screenshots on this page http://www.macstories.net/mac/os-x-lion-installation-guide-boot-discs-and-qa/
Definitely a first for me, installing an OS with voice only
