Recently found my iMac boot up speed is getting slow, so i reinstall Lion from Recovery HD, after about 4 hours reinstallation, it still the same as it was, can anybody tell me how to get back to the manufactory setup.
iMac, Mac OS X (10.7)
Use the Disk Utility on the recovery partition to erase the drive, and then reinstall.

THank you for your reply, but i have no idea how to use the Disk Utility on the recovery patition, i can't see the recovery patition in Disk Utility.
Once you've opened the Disk Utility, click on the regular partition in the sidebar, not the drive, click on the Erase tab, and erase it.

Hi, I try to open the Disk Utility and click on the Macintosh, but the erase button is gray, which not allow me to erase it, the Hard drive i have made 3 partitions, only the other two can be erased ( the button is black)?
You need to do it when started from the recovery partition and not the one with Mac OS X installed.
