How to do a Clean Install of Lion

Hope this will help someone.
I recently did a clean install of Lion on my Mac Pro (after doing an earlier Lion upgrade) and the performance difference is absolutely amazing. Before my Mac Pro was laggy and there all kinds of little glitchy bugs (I'm sorry I can't explain it better than that) with a lot of my applications. Since I use that machine to also administer the network, that just wasn't acceptable.
I'm convinced, after this experience, that a clean install of Lion is the best thing for me, so, this morning I decided to do the same thing to my MacBook Air (IMHO the best laptop ever invented).
Here's what I have done.
1. Download and install Carbon Copy Cloner to the laptop.
2. Clone the laptop hard drive to an external hard drive. I have a Seagate 500GB USB drive which had a 500GB partition with Lion already installed on it. There are instructions all over the web on how to install Lion to an external drive. I used disk utility to add a partition, effectively splitting the partition in two with Lion still installed on one of the partitions and the other partition "clean".
3. Donate to Mike Bombich's site. Carbon Copy Cloner is a remarkable program - I've paid a heck of a lot of money over the years for similar programs and they didn't work 1/2 as good.
4. Go into System Preferences, select the "Startup Disk" applet and select your Lion install on the external hard disk drive as the startup disk. I SUSPECT you could also set the cloned laptop partition as your startup disk, but since the Lion install was already on my external drive, I used that.
5. Reboot the laptop
6. Hold down Command + "R" during the startup process to boot to the recovery partition of the Lion install on the external disk.
7. When the menu pops up, select Disk Utility
8. Repartition your laptop hard disk drive. This will also erase everything on the laptop. You can not repartition your hard drive unless you are booting from an external install of Lion. The recovery partition is hidden so repartitioning the drive will fail if you try to do a clean install from your laptop.
9. When the partitioning is finished, quit Disk Utility and return to the previous menu.
10. Select "Reinstall Lion" and select your laptop hard disk drive as the target.
11. You'll have to authenticate to Apple with your Apple ID, so there should be no problem with downloading and reinstalling Lion.
12. Wait for the download and install to finish. The download will take longer than the install.
13. During the setup, use the Transfer Assistant to transfer the cloned drive items to the new Lion install.
When the TA and install is finished, you should be back to where you started with everything intact.
Good luck!

Clean Install of Lion OS X

Hey , I was curious how to do a clean install of Lion OS X and so that no one can recover any past information.
I am selling it and don't want anyone to be able to recover ANYTHING.

Don't suppose you kept a copy of the Lion installer file? If so, you can make a boot disk using Lion Diskmaker:
http://www.macupdate.com/app/mac/39701/lion-diskmaker as it will save you having to re-download the 4gb+ file.
If not, boot into the Recovery HD (Command+R on start-up) and erase and re-install.
Here's pondini's tips for doing it: http://pondini.org/OSX/Combo.html

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
The system I'm have is a Mac-mini that had SL on it and no SuperDrive. I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
Step 2
After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
Step 3
After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

Welcome to the Apple Support Communities
If you are already using OS X Lion, use OS X Recovery to reinstall OS X and erase the disk. See > http://support.apple.com/kb/HT4718
Follow these steps:
1. Make a backup of the data you don't want to lose after erasing the hard disk.
2. Start your computer holding Command and R keys to start in OS X Recovery, and open Disk Utility.
3. Choose "Macintosh HD" or the OS X partition in the sidebar, go to the Erase tab and erase the disk.
4. Close Disk Utility and reinstall OS X

How can I restore my contacts from a snow leopard time machine to clean instal of Lion

I recently did a clean instal of Lion (which was wayyyyy to difficult by the way--why this wasnt an easy option to begin with I do not know and am not happy about).
In my sleep depravation from the previous problem I accidentally synced my contacts from mobile me to take my computer contacts (deleting all my contacts from my phone and computer).
Fortunately I have a back up on my time machine from my previously installed Snow Leopard.
I tried to restore these files, but they seem to not be compatible.
Steps I took:
1.) -Opened Address Book in Lion
-Opened time machine
notes: i could not go backward in time with lion address book
2.) -Copied files from time machine address book to desktop
-completely unable to open files.
I do not want to use migration assistant because it seems to want to take ALL my files over and frankly thats not what I want to do at all.
PLEASE HELP!

Clean install of Lion....now how to get back my

I did a clean install of Lion on a bare drive. I prefer this much more than the upgrade from Snow Leopard. There's no lag and the system is speedier by comparison.
I have my full back up of Lion prior to the reinstall on Time Machine. I plugged Time Machine back and tried to reintall some files, but instead is ready to add to the back ups, doesn't prompt to format the drive, and I can't go back to put my photos, music, videos, and etc. I also want to restore Keychains since I have used it over the past year for all my online accounts.
Any suggestions is very much appreciated.

I looked up smiliar questions on the groups here. I managed to retrieve most of my data from my old Lion upgrade from Time Machine. The one thing I can't retrieve is keychain.login from Time Machine which as I understand has all my passwords. I used the Option key to find the user directory, but I can't find it through Time Machine. If worse comes to worse I still have my old Lion back up and I can restore that. I like this cleaner install because as I stated above it's quicker.

How to do a clean install go yosemite and then just install certain files, apps, documents, phopt's, etc...from time machine backup?

How to do a clean install of yosemite (have Mavericks 10.9.5 now) and then just install certain files, apps, documents, phopt's, etc...from time machine backup?

Do a backup before doing anything.
If you want to make a clean install of Mountain Lion, boot into the Recovery Volume (command - R) on a restart, use Disk Utility to Verify/Repair the disk and run Repair Permissions. Then erase the hard drive using Mac OS Extended (Journaled) format using the Options button. Reinstall Yosemite. Restart normally and test. Use Setup Assistant or Migration Assistant to import what you want.

Reinstall Apple software after clean install of Lion on 2009 IMac

Completed a clean install of Lion on 2009 IMac, which initially reacted poorly to an upgrade (my first attempt to move to Lion). How do I reinstall iPhoto, Garageband, Aperture, Final Cut Express, iMovie, Logic Express? These were all preinstalled with original purchase. How would I find the serial numbers that will inevitably be asked for? The App store wants to charge for these items, and other non-Apple software I've purchased for the App store won't download again. Multiple issues! Any suggestions?

You'll need to use the DVD's that should have accompanied your system when you bought it.
Prior to the App Store when you purchased a system from Apple that included installed software such as iLile or Final Cut the DVD's were always included in the box. The serial numbers will be on the DVD boxes or DVD's themselves.
regards
Concerning the App Store purchases if you long into the APp Store using the same Apple ID you used when you bought the software you should be able to download again without charge. At least this is how it works for Apple software don;t know if 3rd party stuff has different rules

Since you seem to be using a new disk for Lion, Time Machine will consider previous backups to be for a "different" computer. Try doing a control-click or click-and-hold on the Time Machine icon in the Dock, then choose "Browse Other Time Machine Disks". This should allow Time Machine to see the previous backups.
In the worst case you should be able to open those Time Machine backups and copy your documents from there to your home folder.

Why are old Snow Leopard services showing up in a clean install of Lion?

I perfomed a clean install of Lion on the internal backup drive of my Mac Pro. Very clean indeed,...I even zero'd the disk before starting. I ran Snow Leopard for a few days after that while I got Lion up and running, and eventually mirrored my Lion install back over to may main boot SSD,...eliminating Snow Leopard altogether. At no point did I follow any of the optional offers to migrate or transfer data from a previous install of any other OS.
And things seemed fine until yesterday, when I noticed services for apps that I have never installed (on Lion) appearing in the contextual menu of files. In other words, if I option click on a .zip archive, I get the option under "services" to "Extract with BetterZip".
What? Just wondering how this could happen, and if this cruft somehow made it through...what else? I did of course run BetterZip in 10.6,...but, I am stumped to account for how it's been added to the pool of services in Lion.
Ideas? And/or tips for removing these legacy services?

[BUMP]. Still, no idea. But I can't believe I'm the only one experiencing this.
