Confused about what to select

[caramellhoney]

Im selling my MBA tomorrow. I rebooted in recovery mode and I'm stuck. Im not sure which disk I'm supposed to delete. I'm following the directions from the apple page but it just keeps saying "startup disc"
On my computer I see the following

My guess is the top-one. The other one doesn't look lige a built-in drive. Try check the sizes.

Go to the first Macintosh HD, erase it on the erase tab, then close Disk Utility. Go to install/reinstall OS X and internet recovery should download a fresh copy of Yosemite and install it for you. You can then boot it up and configure it if you want. Or hit Command + Q at the setup screen to keep it like new for the next owner. Should be pretty simple.

It only gives me the option to erase the second Mac Hd

That should work too. It's just the partition that holds all your stuff. Usually you can erase the first, but perhaps not with the recovery partition since they are on the same disk. I've yet to use internet recovery since I always end up using a flash drive so I don't have to download the whole OS every week.

It worked. Thanks.
