Zythyr Posted March 23, 2012 Share Posted March 23, 2012 I followed this guide, http://wiki.osx86pro...ps#Optiplex_745, to install Lion onto my Dell 745. I managed to get the installation to work fine, however I am having the following problems that is preventing me from continuing the configuration process of my installation (installing kext, installing chameleon, etc...) 1) Everytime I boot, I have to use the bootflag "-x -v rd=disk1s2". I am forced to boot into safe-mode. If I don't boot in safe mode, I get stuck on a black screen with a cursor. I also tried using the bootflag "GUI=No GraphicsEnabler=No" to see if that would fix the problem so I don't have to boot into safe mode. However, that didn't fix the issue. 2) Because I have to boot into safe mode, I can't mount my USB drive which contains all the kext and tools I need to configure the installation. The specs of my dell are: Model:Dell Optiplex 745 DCSM Processor: Intel Core 2 Duo @ 2.40GHz Front Side Bus: 1066MHz 4096KB L2 Cache 4096MB Dual PC2-4200 Hard Drive: 500GB Sata Ram Speed: 533MHz 3.0GB/S Link Speed 64-Bit Capable Radeon X1300 256MB CDRW/DVDRW,DVDROM Sata Optical Drive Ethernet Functional Audio Functional Video Functional http://www.dell.com/...45techspecs.pdf Link to comment https://www.insanelymac.com/forum/topic/277401-help-w-lion-installation-on-dell-optiplex-745/ Share on other sites More sharing options...

Zythyr Posted March 25, 2012 Author Share Posted March 25, 2012 try booting with following flags -v "Graphics Mode"=1024x768x32 rd=disk1s2 what are your bios settings??, how did you install lion (method)?? Using the bootflag "Graphics Mode"="1024x768x32" also didn't work. I used this method to install lion, http://www.insanelymac.com/forum/index.php?showtopic=256729. Could the issue be related to my graphics card, Radeon X1300? Or the integrated graphics card, GMA 3000?

d620osx Posted March 28, 2012 Share Posted March 28, 2012 As suggested in the other post try without the graphics card. When I tried installing with a quadro NAS 280 I had the same issue. Once installed if you put the card in it should be okay. Not sure if the ATI cards works.
