Hi everyone. I have been gifted my friends old iMac and have been having trouble with the computer as of late so I decided to do a complete resintall of the OSX. The computer I am using is a iMac 21.5'' 3.06 GHz Intel Core 2 Duo late 2009. I created a bootable version of OSX Lion 10.7 from app store purchase on a 8 gb usb drive. Computer reads it and everything. The installation begins but with about 1 min left I get a message stating "Can't download the additonal components needed to install Mac OS X. I have also just tried to boot from apple servers using the command R but it gets stuck at a certain part each time, not to mention it takes HOURS for it to even get to any part. The HD seems fine when Verifiy Disk with no errors.
