arghargh Posted April 24, 2013 Share Posted April 24, 2013 Trying just to get a bootable USB. I used myHack to create a Snow Leopard bootable USB. D820 just ends up at a blank screen with a flashing cursor when I try to boot. A couple of things bother me. 1. We creating the install from myHack I get an error about having to run myFix. 2. I run myFix and that seems to work. 3. I install Extras from from EDP SnowLeopard for D820/NVidia Try to boot...epic fail. Is there something obvious I am missing here? Thanks.

iMick Posted April 24, 2013 Share Posted April 24, 2013 Have you exactly followed our EDP documentation?Because I don't see something like your third step in our documentation . Link to comment Share on other sites More sharing options...
arghargh Posted April 24, 2013 Author Share Posted April 24, 2013 Step 3 I am referring to is below.... I created the USB installer with myHack, and before I try and boot it looks like I have install EDP, right? "Now that you have created your USB installer with myHack, we need to put the EDP bootpack on it. Download the EDP bootpack, customized for your system! Our bootpacks contain almost every kext (driver) you need, except the battery and audio driver. Our target is to make the install as easy as possible, so we excluded high risk factors during installation. Choose the bootpack for the same OS X version as you made your myHack USB. Open myHack again and choose: “Install Extraâ€. Choose as target volume the USB installation pen. Choose “Use My Own†and select the Extra folder, from the downloaded bootpack. Quit myHack and eject your USB pen, you are ready to go! " Link to comment Share on other sites More sharing options...
arghargh Posted April 24, 2013 Author Share Posted April 24, 2013 Ok, I am getting a bit further along. The problem seems to be that when creating the installer from myHack it copies OSX there just fine, but errors looking for myHack.kext. At that point I assume the other steps (like Chameleon) never get run. I tried run each option by hand (including the EDP) and now I can boot the US, but I get: BOOTMGR is missing. Clearly this has something to do with myHack.app not preparing my USB correctly. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 24, 2013 Administrators Share Posted April 24, 2013 Re-run myHack and select "install Chameleon"; target your USB installer. it looks like you're without bootloader. I assume that when you 1st created the myHack installer, you opted for "10.6 installer", right? Link to comment Share on other sites More sharing options...
arghargh Posted April 24, 2013 Author Share Posted April 24, 2013 Took another direction. I managed to track down my Lion install. myHack still gets an error, but seems to get much further. I installed myFix, and EDP on USB drive, but now when I boot I get: boot0: GTPboot0: testboot0: testboot0: error Whoa no, cancel that. I installed Chameleon again and it boots...let's see how far I get now! Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 24, 2013 Administrators Share Posted April 24, 2013 Presumably, when you say "EDP", you mean OSXL bootpack. EDP is a totally different thing: it's the tuning tool to get your final installation in place. Link to comment Share on other sites More sharing options...
arghargh Posted April 24, 2013 Author Share Posted April 24, 2013 Bingo. I wish I remembered which combination of things made it work. Last thing I did was re-install the extras and it booted into the install. Thanks for the guidance. Link to comment Share on other sites More sharing options...
arghargh Posted April 24, 2013 Author Share Posted April 24, 2013 During install issues now... 1. If the screen goes to sleep it won't wake up even though the install is still running. 2. If baby sit the install and keep the screen active the install finishes, but when I try and boot off the disk I just get a blank screen and a flashing cursor. 3. If I boot off the USB and then try to run the hard drive OSX (as opposed to the install) I can see all kinds of debug but eventually hangs. Can someone verify the myHack steps. Do I create the installer first? If I see errors do I just run the other steps manually (and in what order). Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 25, 2013 Administrators Share Posted April 25, 2013 The display sleep issue is a known one; it also affects the D620. It's to do with the nVidia chip; it's probably something to do with DSDT. Basically, if the display goes to sleep, it'll only wake to a grey screen. In that case, the best you can do is put the entire computer to sleep and wake it. For the rest, it still sounds like you're still without bootloader. You're probably not following the procedure 100%. Link to comment Share on other sites More sharing options...
