Hello All, I have a late 2009 MBP and got a new battery and SSD to try and give it a few more years. There is nothing wrong with the HDD in it now just wanted a bigger faster drive. I tried to create a boot-able flash drive with Mavericks on it, but was unable to get it fully installed. I have tried multiple different flash drives and forum posts with no avail. I finally went and picked up a Snow Leopard install disk at my local Mac store but cannot get the computer, with the SSD installed, to boot from the disk. When i hold 'option' down while booting it shows the icon 'boot from Install Disk' but after selecting it it just sits on the Apple logo w/ gray background. Do i need to do any setup on the SSD before installing the new OS? And the computer had the most updated Maveriks on the old HDD. Thanks for any help!
