View Full Version : [ubuntu] converting a primary partition to an extended one

July 19th, 2009, 11:25 AM
Hello people,

I hope this is the right place for such a question. If it's not, I'm sorry, I apologize.

The subject says it all. I have 2 primary partitons on my drive:

/dev/sda3 is an extended partiton and contains a logical partitioon for the swap and another logical partition for my Ubuntu installation
/dev/sda2 is a primary one, it used to contain XP now it's formatted in ext3 and I use it for data dumps

I'd LOVE to be able to convert /dev/sda2 to an extended partiton and inside that I'd put another bunch of logical partitions because I'd love to install Arch Linux also, to experience a different distro.

Now, the partitions editor doesn't allow me to do that. There's a menu item but it's greyed out and not available.

I don't see why. :-( What am I missing ?

Thanks so much for any hint

Like this:


Of course I deleted the partition and tried to create a new extended one in the empty space, but as you can see, only the first item is available, the other two are not.

Thanks again for any help

Hi, you can only have one extended partition per hard drive.
