elite-fusion Posted January 3, 2012 Share Posted January 3, 2012 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 Link to comment Share on other sites More sharing options...

elite-fusion Posted January 3, 2012 Author Share Posted January 3, 2012 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.

art_4 Posted January 19, 2012 Share Posted January 19, 2012 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.

chasmataz Posted February 9, 2012 Share Posted February 9, 2012 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.
