E6420 Help Please


Recommended Posts

Hey guys, I am completely new to OSX on PC's, so please bear with me.


I have a Dell Latitude E6420 which I recently got from my company, obviously its a company computer so I swapped out for a new hard drive in order to set it up how I want during home hours and when at work, just pop the other hard drive in.


I would like to set up a Dual Boot with Windows 7 and Lion X 10.7.2 but I have no idea at all where to begin.


I have tried 2 times already with a disc that a buddy downloaded and burned for me of some version that is meant for Intel processors, but that did not work.

I did set SATA to AHCI but it still did not work. Once CD is in, it goes through the black screen, then it goes to the whitish/grayish screen with the Apple logo and the little spinner on the bottom, it does the spinning for about 15 minutes, and then the spinner freezes and 5 mins after the CD stops spinning as well, I figured I'd let it sit there for a while but 10 minutes after the CD stopped spinning, I got a message on the screen saying I have to restart the computer and to press the power button, so it obviously did not work.


I have been looking for the past 2 days already, I really would like to get Lion on this machine. I already have Windows 7 installed. The HDD is 300GB, I have split the HDD into two partitions, One is a 150GB Unformatted Primary partition, and the other is a 150GB NTFS Secondary partition which has Windows 7 on it installed.


Can someone please help me install Lion on this machine. Any help would be greatly appreciated. Thank you in advance :)

I have gotten Snow Leopard installed but looks like when it turns on, i get a white screen with nanoseconds error on it. I used the MY86OSX boot loader and Snow Leopard DVD, went through installation fine, but then once it restarts after completion, i get the screen.

As way of testing, I got a basic install to work on a e6520 (the same as yours but larger display and keyboard). I wanted to use the instructions here because I have access to a d630. But I rashly bought the lion USB stick lather than download lion... and this site only seems to have help for the downloaded copy. So to use the copy I already have, I used the instructions on lifehacker. I can tell you that lion loads and is quite fast.


Working: Wired NIC; intel video;


Not working: Always complains that it does not see a keyboard; WIFI NIC; Closing the lid is not detected; Sleep. During the install, a usb mouse and keyboard were required.


As my real goal is to get this installed on a d630, I do not plan to trouble shoot this, but I will tell you if I figure anything out.

i have an E6400 booting Lion 10.7.2 from external usb drive with windows7 on the internal drive.

the osx system is my backup drive from my latitude d630 using edp2.1.

i used no boot flags except "-v" and it booted with no kp what so ever, like it was a mac.

i guess i'd start there to get her running and then fine tune things like bluetooth etc.

the windows7 boot recognized the mac os and i didn't even need to install chameleon

so basically i'd follow the guide for the d630/intel. unless your 6420 has the nvidia card, then of course choose that.
