HOW TO INSTALL OS X ON T420 IBOOT PASSWORD

In the Terminal window once you type 'sudo' & the command, you'll have to enter your password to execute the command. Using 'sudo' is sort of like 'assuming the identity of root' from now on. You can arrow down to go down the page & press 'q' to 'quit' & get out of info.

I suggest you take a couple of minutes to get the info on 'sudo', by typing (yup, you guessed it!!) 'info sudo' in the terminal window. You need to use 'sudo' to make the command work. Since you probably don't know what that means, you can't use the command. I suggest you take a moment to understand what you're going to do next.ДЇirst, you will not be able to use MacMan's command unless you can su to root first. Unmount the the first drive you built with the boot0 error, the 'not booting' drive, that's named 'Snow Leopard HD'. * Once your system is up, open Drive Utility. * Boot the system (to the only drive that works). If your drive is 6GB/S drive, you can now move it to the white SATA controller port too. * Put leave the smaller (good) drive in the system & put the bigger (not booting) drive in with it. * Once THIS drive is built, you will NOT have the boot0 error, unless they change the architecture on the smaller drives too. ** NOTE ** I suggest that you name the partition something simple, like 'Mac HD' & NOT the same thing you named your other boot partition. * Install another 500GB HDD (could use a drive as small as 20GB as long as it's SATA or Solid State) & install SL exactly the same way on this drive, EXCEPT make only 1 partition as per TonyMacx86's original instructions. * When 'done' have boot0 error, so remove this HD for now. * Install Snow Leopard as per 'regular' instructions. * Use Disk Utility to slice 1.5TB drive at 600GB boot partition, named 'Snow Leopard HD' & the other 900GB partition named 'Extra' * Build system as per instructions with 1.5TB HDD installed (you'll have to slice it up once you get to the installation). * Download Multibeast for Snow Leopard & save to USB Flash drive. & save to USB Flash drive with your DSDT.
