It sounds like you destroyed your boot partition and the recovery partition. Depending on it's age, your MacBook Air might be able to do a net boot. Plug and ethernet connection into it and attempt to boot. If it has the right firmware, it will find a net boot configuration on the net and boot that. Then it will give you a Recovery Partition like display and allow you to reinstall the OS X version that came with it.... assuming that it was Lion or ML. If your computer came with Snow Leopard, then even the net boot won't work.
At that point you need a bootable USB Key, or an external DVD drive AND a Snow Leopard installation DVD.
An Apple Store, if there is one nearby, MAY be able to get you going again. However, whatever is on the SSD now will be toast too.

I have somehow started getting bing instead of google as my search engine for my mac air. does anyone know how to remove this?

I have begun having bing as my search engine instead of google on my mac air. I have no idea how this happened and wish to remove it but am stumped. Has anyone had experience with this?

You may have installed the "Genieo/InstallMac" rootkit. The product is a fraud, and the developer knowingly distributes an uninstaller that doesn't work. I suggest the tedious procedure below to disable Genieo. This procedure may leave a few small files behind, but it will permanently deactivate the rootkit (as long as you never reinstall it.)
Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data. You must know how to restore from a backup even if the system becomes unbootable. If you don't know how to do that, or if you don't have any backups, stop here and ask for guidance.
Step 1
In the Applications folder, there should be an item named "Genieo". Select it and open the Finder Info window. If it shows that the Version is less than 2.0, download and install the current version from the genieo.com website. This may seem paradoxical, since the goal is to remove it, but you'll be saving yourself some trouble as well as the risk of putting the system in an unusable state.
There should be another application in the same folder named "Uninstall Genieo". After updating Genieo, if necessary, launch "Uninstall Genieo" and follow the prompts to remove the "newspaper-style home page." Restart the computer.
This step does not completely inactivate Genieo.
Step 2
Don't take this step unless you completed Step 1, including the restart, without any error messages. If you couldn't complete Step 1, stop here and ask for instructions.
Triple-click anywhere in the line below on this page to select it:
/Library/Frameworks/GenieoExtra.framework
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.
If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder should open with an item named "GenieoExtra.framework" selected. Move that item to the Trash. You'll be prompted for your administrator password.
Move each of these items to the Trash in the same way:
/Library/LaunchAgents/com.genieo.completer.update.plist
/Library/LaunchAgents/com.genieo.engine.plist
/Library/LaunchAgents/com.genieoinnovation.macextension.plist
/Library/LaunchDaemons/com.genieoinnovation.macextension.client.plist
/Library/PrivilegedHelperTools/com.genieoinnovation.macextension.client
/usr/lib/libgenkit.dylib/usr/lib/libgenkitsa.dylib
/usr/lib/libimckit.dylib
/usr/lib/libimckitsa.dylib~/Library/Application Support/com.genieoinnovation.Installer~/Library/LaunchAgents/com.genieo.completer.download.plist
~/Library/LaunchAgents/com.genieo.completer.update.plist
If there are other items with a name that includes "Genieo" or "genieo" alongside any of those listed above, move them as well. There's no need to restart after each one. Some of these items will be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
Step 3
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including ones called "Genieo" or "Omnibar," and any that have the word "Spigot" or "InstallMac" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Your web browser(s) should now be working, and you should be able to reset the home page and search engine. If not, stop here and post your results.
Make sure you don't repeat the mistake that led you to install this software. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad has a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If youever download a file that isn't obviously what you expected, delete it immediately.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Genieo developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. It must be said that this failure of oversight is inexcusable and has seriously compromised the value of Gatekeeper and the Developer ID program. You cannot rely on Gatekeeper alone to protect you from harmful software.
Finally, be forewarned that when Genieo is mentioned on this site, the developer sometimes shows up under the name "Genieo support." If that happens, don't believe anything he says, but feel free to tell him what you think of his scam.

System Preferences - Users and Groups - Login Items - remove any that you don't want on startup.
Don't forget also that Lion will automatically restart any apps you had open when you shut down, unless you untick the "Reopen windows when logging back in" tickbox that appears.

I have inastalled Lion on my Mac Book Air and I have really problems. By application that are not from Apple the processors is 80 degrees celsius warm after 2-3 Minutes from the start of the Apps.How can I downgrade 2 Snow Leopard without 2 loose my Data?

Can I use the Lion licence with my MacBook Pro if I downgraded my Air?

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
If there are specific tasks you need help with:

This isn't the fault of firefox. Firefox is a web browser, not your email provider. I'd suggest contacting them (whoever you use, gmail, yahoo, etc.) and asking for help.

Mac air start up,then pop-up yahoo mail screen, and ask me type password..how can i cancel it

Mac air start up,then pop-up yahoo mail screen, and ask me type password..how can i cancel it

Ok, finally I figure it out!!
You need to give computer access to the password of Yahoo.com
You go to the application "Key Chain" that is included in your MacBook Pro.
Then you go to the first tab that should say something with "Login/Session" and you should see all your saved passwords.
Scroll down to the saved password of "Yahoo: your-username @ ...
Click on it, you should see a window opening
Go to the tab "Access Control"
Then click on "Allow all applications to connect .. ", NOT the option "Ask every time for allowance" or you can also just add the program "MAIL" with the "+" icon !!
There you go, now you should not have to worry again !!!!!!
(this step copy form someone posted)
Anyway can fixed it!!!!!

Every time I restart my mac air some applications like calendar and Microsoft word automatically starts, how can I stop such applications from starting when ever I restart my mac?

One thing to check: when shutting down or restarting, there is a checkbox in the shutdown/restart dialog which asks whether you want currently open applications to open at startup.

How do i get a bigger start up disk installed in my mac air?

Currently i have everything saved onto my external hard drive. There is absolutely noting on my mac in terms of memory. I have started doing some video editing and have noticed the computer freezing and working slower. The start up disk is the basic size and i would like to increase the size to help speed up the computer.
How do i do this?

The MacBook Air is not user upgradeable and though some try to do so themselves, that will void any support and service from Apple.
Ty contacting your Apple store genius bar and see if they have the ability to upgrade the solid state storage on an MBA. Or, you can try to find an Apple Authorized Service Provider as they usually can install a new SSD for you.

Mac air is frozen. When I reboot it freezes again. How do you get it unstuck?

Tried rebooting but the screen is frozen. How do you unfreeze the screen?

Hi I am having a problem re: having to keep doing internet recovery this is after they erased my data and said it was a corrupt file, I keep getting disk utility errors saying unable to fix. Last night the laptop turned on when I had the lid closed and shurt down (I could hear the sign on music) so went to check it out and it would not sign on black screen for quite a bit then I got a wake/sleep error. Anyways, not sure what is going on....mine is 2012 model I got it a year ago in January, have had a few problems with it, I do have the 3 year warranty which I think it a waste of money. Thinking of taking it to a computer shop instead, don't seem to get things sorted out at Apple and the store was really rude last time I went in there so don't really want to go in there.
Anyways, thanks.
