How do you completely remove Ubuntu 11.04 from a MacBook?

Answer 1

When an operating system such as Ubunto is installed on a Mac, a disk partition is created on a hard drive. Then the OS is written to the partition, and shows up as a start up drive when the Option key is pressed during start up.

To remove Ubuntu, just remove the partition from the hard drive.

This is done using the Disk Utility application.

NOTE! Everything you created using Ubuntu, including pictures and documents, may also reside in that partition. When you remove the partition, you will also lose all the documents you made which are in the partition. So, if you have items that you want to keep, move or copy them to other places on other hard drive partitions. Then you can delete the partition with Ubuntu on it.

Open Disk Utility.

Take care! this is a powerful application which can delete partitions which are necessary to the Mac, and if you delete them, your Mac may not work until you start up from a DVD with a boot-able system on it and reinstall a working OS. Don't erase the hard drive or partition. You want to change the partitions.

You will see the list of hard drives and partitions on the left. Select the Hard drive that has the Ubuntu partition listed underneath. Click "Partition" in the top of the right window. You will see the partitions and how much space they are using on the hard drive.

There is a line between the partitions, like a window shade.

Click inside the Ubuntu partition.

Be sure that you have clicked only on the Ubuntu partition!

See the + and - under the window?

Click the - sign. The partition will be deleted, and its disk space will be made available to the other partitions on the hard drive.

This can not be undone. Be sure that you want to do this.

If you delete the partitions with operating systems on them, you will have to get an install DVD and install a working OS before your computer will start up.
