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

Using the bootflag "Graphics Mode"="1024x768x32" also didn't work.

I used this method to install lion, http://www.insanelym...owtopic=256729.

Could the issue be related to my graphics card, Radeon X1300? Or the integrated graphics card, GMA 3000?

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.
