Sandisk Extreme 480GB SSD on Macbook Pro 15 inch mid 2012

I realize that you’re saying you cannot get the system to see the drive to boot off of, so the reason I’m asking you to make a USB Lion boot drive is to get disk utility open when the SSD is installed into the computer.

IF you get to disk utility from booting off the Lion USB thumbdrive, and the SSD still isn’t showing up at all within disk utility from there, then something is wrong. 

  1. Create Lion boot usb thumb drive

  2. Turn off computer

  3. Install SSD into computer

  4. Boot off of Lion usb thumb drive

  5. Open up disk utility from the top menu after booting from Lion usb thumb drive

  6. format SSD / create guid partition table on SSD

  7. Install Lion onto SSD

  8. Success?
