Omer Mushahwar :

Hi I am one of the experts here on Just Answer.cin

Omer Mushahwar :

just answer.com sorry

Omer Mushahwar :

The easiest way for your to completely wipe the mac book air is for your to completely reinstall the operating system

Omer Mushahwar :

Or if by chance all the information is simply inside your user profile you could simply setup a new use on the mac book air and then delete your user account

Omer Mushahwar :

Hello and welcome to Just Answer.com

Customer:

I use the small Reinstall Drive, in fact twice, but all my files etc. are still on the computer

Omer Mushahwar :

Now when you went to reinstall the OS did you first delete the current hard drive partition that has all your data in disk utility and then create a new partition so you were completely reinstalling as opposed to simply repairing the operating system

Customer:

Frankly, I do not know what a 'hard drive partition" is. SO...No I did not delete the current hard drive partition.

Omer Mushahwar :

Also for your macbook air do you have the external dvd drive

Customer:

No

Omer Mushahwar :

And you said you have the operating system on a USB drive?

Customer:

Yes

Omer Mushahwar :

ok one second just want to make sure I understood your full setup

Customer:

Yes, I have the USB flash drive, which contains a backup copy of my MacBook Air software.

Omer Mushahwar :

Ok First I would like you to connect the USB Drive

Omer Mushahwar :

then shutdown your macbook air

Omer Mushahwar :

  1. Press the power button on your computer, then press and hold the "C" key when you hear the startup tone.

  2. You can also power the computer on and press and hold the Option key when you hear the startup tone, then click on the icon to startup using the MacBook Air Software Reinstall Drive.

Omer Mushahwar :

Once the computer boots to the drive

Omer Mushahwar :

you will have some options to work with the Hard Drive

Omer Mushahwar :

Are you working on the macbook air now

Omer Mushahwar :
