Plese explian, How to go back to lion from mountain lion?

Time Machine does not provide bootable backups. Therefore, this is not the solution.
If you bought Lion, you should be able to re-download it from the Mac App Store. (Sadly, Apple pulled the ability to actually buy Lion off the store). You should be booted to another volume other than the one you will be installing to. You may have to disable the installation on the disk you wish to move back to Lion. I'm not certain, but suspect that trashing the ML System folder would do the job. The Installer will probably notice the missing OS and allow the Lion install. If not, then you'd have to go to the root directory of that volume, make invisible files visible and trash the 'Kernel' files and try again to install Lion.
Ideally you can use the Time Machine backup to restore just about everything else. But you may find everything works fine after the install.
I beta tested 10.8 Mountain Lion and know that it had a couple remaining bugs upon release. That's what updates are for. I expect there will be a rapid release of 10.8.1 update via the Mac App Store. It may well be worth hanging in there with 10.8. It is most definitely an IMPROVEMENT over Lion, whose Finder bugs I absolutely hate. (But that problem may soon be solved with the 10.7.5 update coming soon).
If you look around the net you'll find there are instructions for creating a bootable Lion installer DVD or USB thumb drive as long as you have the Lion Installer on a hard drive. Here are a couple with illustrations:

How to revert back to Lion from Mt. Lion

I have a 2009 IMac. I have no problem upgrade from Lion to Mt. Lion. The only issue I have is the IMAC is very very warm, 55 degree on CPU and between 65 to 70 on GPU diod. I want to revert back to Lion which I paid and downloaded in 2011. The App store would not let me redownload again said that I have a newer system. Since I downloaded the Lion, I do not have any installation disk for Lion.

You need to first erase the hard drive:
Install or Reinstall Lion/Mountain Lion from Scratch
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 Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your startup volume (usually Macintosh HD) 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 Erase 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.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Installed new hard drive, loaded Snow Leopard from disk, how to get back to Lion?

Our 2006 24" iMac, 2.16 C2D (EMC 2111) running the most up to date version of Lion had a hard drive failue. I replaced the hard drive and used the Snow Leopard disk we had to load the OS X. During installation I went through the migration assistant to load our most recent Time Machine backup. It loaded all apps and files just fine, but it did not update the OS to Lion. So, many of our most used applications (Aperture, iTunes) were versions that won't run on Snow Leopard 10.6.8. I thought I could just go to iTunes and view my purchased items and redownload Lion from there, but iTunes version installed from the backup doesn't work with anything less than 10.7. So, I erased the HD, re-installed Snow Leopard and did not use the migration assistant this time. Thinking I could run iTunes and get my Lion purchase downloaded and then resotre from Time Machine. That doesn't appear to be working. I've updated a couple of times, including iTunes, and it doesn't appear that I can find Lion. Would it be in my iTunes library on my external? I haven't reconnected my external yet as I don't want anything to be modified during this attempt to fix things.
How do I get Lion re-installed from this point? I paid $29.99 when it first came out. The iMac won't run Mountain Lion, which seems to be available for download.

Yes, the retail version of Snow Leopard is a full install that can be put on a blank drive.
Order a Snow Leopard 10.6 install disk for $29 from The Apple Store as long as you have at least 1gb of RAM. http://store.apple.com/us/product/MC573Z/A?mco=MTY3ODQ5OTY
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window.
Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. You should see your hard drive in the left hand column along with your other drives. Click on the drive and select the Erase tab. Set the format value to Mac OS Extended (Journaled) and click the Erase button. After that has finished select the Partition tab. Type in a Name for your hard drive and select how many partitions you want from the Volume Scheme. The usual setting is one partition. Click on the Options button after you've selected a partition to make sure it's set for GUID. Then click the Apply button and after the Partitioning is done quit Disk Utility.
You can now follow the instructions on the install screen
To upgrade your iLife and iWork. If you only want iPhoto or other single apps from iLife '11 you can get them from the App Store after you've upgraded to 10.6.6. iPhoto, iMovie or Garage Band for $15 each and Pages, Keynote or Numbers from iWork '09 for $20 each.

How can you get OS Lion back if you already downloaded Mavericks? I CANNOT live with the battery life of 2 hours!! HELP

Don't downgrade OS X without first erasing the drive. You cannot restore a Time Machine backup of Lion directly on top of a later version of OS X such as Mountain Lion or Mavericks.
When you "Restore from a Time Machine Backup.", the drive will be erased for you, but yes, won't hurt to:
Boot into Recovery (hold ⌘R on boot)
Utility->Disk Utility->Erase Macintosh HD, then Repair Macintosh HD
Quit Disk Utility
Then Select: Restore from a Time Machine Backup.

A erase of the drive or boot partition is not always necessary.
Flashing question mark at boot could be a easy fix, sometimes it's the firmware that simply forgot what bootable volume to boot from.
Try holding the Option key down while booting the machine, a choice of bootable options appears, select your OS X and boot up.
When you get in, head to System Preferences > Startup disk and set it again new. This will tell the firmware what to boot from. Test it to see.
Now if you don't have a selection of bootable options, it could be that the drive is dead, or OS X is erased or corrupted so it can't boot.
You'll have to run through this list of fixes to see what's going on, if you need a hardware fix or what, I've also included links if you can't fix it and need to recover your data etc.
(If it's not remmebering your boot selection then also run through the list to reset things.)

How do I downgrade mountain lion back to my mac mini 2011 lion server

Hi,
Previously, my mac mini mid 2011 was installed with mac os lion server then I have purchase and upgrade to mountain lion via iTunes.
Somehow I decided to downgrade back to lion server due to use of my mac as server, unfortunately I have no idea how to downgrade with the following reasons:
1. I don't create any time machine backup before so can't use that option.
2. I have enable vault function so now the startup has hide the recovery HD icon
3. In the Recovery mode (command + R), I only see an option to download and reinstall a fresh Mountain Lion only.
4. I can't download and install Lion server from iTunes because this os was bundle with purchase of mac mini 2011 mid version.
Any comments and helps here are appreciated. Thanks.

Well, did you save a Carbon Copy Clone (http://www.bombich.com) of the Lion installation by chance? That would be the easiest to go back to and use / update. Outside of that, or having saved the original Lion installer, I know of no way to get the OS that you are after. For future referece, on a mac mini with two harddrives, I have always made a backup partition on the second drive using CCC, and schedule clone updates to that. You can't rely on TM, inmo, so something like CCC or SuperDuper is essential. Cheers,

My laptop hard drive crashed, used to have lion now it is back to snow leopard. how do i get it back to lion again?

my laptop hard drive crashed, used to have lion now it is back to snow leopard. i lost all of my info, music, pictures, etc. how do i get it back to lion again? this is very frustrating because i paid $30 to download it and now i am unable to have it again.

If your Mac is off then start up. As soon as you hear the boot chime, hold down the Option key until the Mac and Windows Disks show up. Then click on the Mac disk and the arrow below it. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk.
If you are in Windows then look for the Boot Camp icon on the taskbar. It will look like a gray box sitting on one corner. One of the options when you click it is to restart in Mac OS. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk.

NicholasLiban -
When you use the Lion restore as described, it does a fresh install on the hard drive that you can select at the beginning of the process. This provides a complete install of the very latest version of Lion, including the recovery partition. The drive that you choose for the installation destination winds up like what you would have on a brand new computer from Apple.

How do I erase mountain lion developer preview and go back to Lion 10.7? I do not have lion or data backed up on my Air

How do I erase mountain lion developer preview and go back to Lion 10.7? I do not have lion or data backed up on my Air
I need a step by step instructions since I have never done this before, willing to set up partition if needed.

If you installed Lion from the Mac App Store or got it with the computer, restart with the Option key held down and see if its recovery partition still exists; if it does, tab to it, use the Disk Utility on it to erase the Mountain Lion partition or repartition the drive, and install Lion onto the blank partition. If you installed Lion from the USB thumb drive, use that.

MacBook pro does not start. How can I back to Mac OS X Lion?

I have a MacBook Pro. On my MacBook i made three partition, then I installed window 8. After that I started windos and try to delete third partition by Administrator tool from windows operating system. After that my MacBook does not start. How can I back to Mac OS X Lion?
After that I again install windows 8 from a DVD. Windows start well, but I can not start Mac OS system, may be it was 10.6. Sever times I tried to install OS X Lion 10.7 thought DVD, I could not. On MacBook I have a lot of important data.
What can I do. I want to a complete suggestion. Please help me to solve the problem.
My MacBook Pro model no. A1286.

You installed Windows improperly the result of which was to wipe out the bootloader for OS X. You can give this a try:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the OS X disk icon from which you want to boot.
5. Click on the arrow button below the icon.
If you are still unable to boot from the OS X volume then you will need to reinstall OS X:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
This will destroy the Windows bootloader so you cannot boot into Windows. The solution is to remove all the partitions on the drive except the OS X partition, then expand the OS X partition to take up the entire drive.
Use Boot Camp Assistant in the Utilities folder to create a Windows partition on which you can install Windows. You cannot have any other partitions on the drive besides these two.
Now given all the above you may be able to install a third-party bootloader that would work with the setup you now have: Boot Runner 1.4.

How to go back to Mountain lion os x 10.8 again from mavericks.?

How to go back to Mountain lion os x 10.8 again from mavericks.?

You can reinstall your system from a backup (Time Machine or "clone") or erase it completely and reinstall Mountain Lion.
OS X Mountain Lion: Erase and reinstall OS X
If your Mac shipped with Mountain Lion already installed, you can reinstall it. Otherwise, you can only reinstall Mountain Lion if you purchased it from the App Store.
You may be better off describing the problems you're experiencing, so that they can be fixed. The vast majority of Mavericks complaints are due to outdated or poorly written software or similarly incompatible system modifications, and some simple troubleshooting may reveal the cause.

How do i get OSX LION back on the computer?

I dropped my laptop and the hard drive is no longer working. I am going to purchase a new hard drive and install it but my question is how do i get OSX LION back on the computer? I will be installing a new bare drive and I heard that Lion is download only. I also want to make sure i get all the apps i had back too. any help or guidance is appreciated. thanks!

this is my opinion. but in this case, you need to install previous OS that has a dvd, which in my case, i installed Snow Leopard first. it cost 30 dollars new.
after you have SL operates and do all software updates, you can download lion and install it over snow leopard.
hope someone here have a better and quicker solution straight to Lion.
