I accidentally deleted my startup disk (Macintosh HD)

EASIEST WAY!!!

Same thing happened to me. I watched tutorials video online but they require you to open the laptop itself but I figured out how to fix this problem

(Installing the os but no drive to place it) heres the solition)

When you restart your laptop you have to press the commad+ R and go to the disk utility

Click the disk002 or something you have to click the partition its where the restore/erase button

Click partition then choose mc extended journal ( o forgot the whole name)

rename it MACINTOSH HD and apply or continue

Then you have it!!! Once its done you can go back to install the original OS then the mcintosh hd will show!!! VIOLAAA

While we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

"deleted my startup diskl" No problem:

Since you run Lion:

startup while holding the Alt(option) key:

you will be shown the possibilities to start from:

choose the "recovery disk".

Then reinstall Lion from there. Make sure you have internet access.

i have the same problem but when i go to recover using lion it says my recovery hd is locked

Hold Command + Option + R + P before your Apple logo shows up. Hold it until your second reboot. and you will be able to redownload fresh copy of Lion from Recovery mode. Make sure you bought a OS X Lion in Mac App Store!

i tried that but when i go to redownload lion it says choose a start up disk and the only one is recovery hd but it's grayed out and says its locked
