stevenplanet Posted July 8, 2012 Share Posted July 8, 2012 Hi guys! So complete NOOB here. But hoping to change that with this OSX installation. I have a Lenovo Thinkpad T420 4177 with Intel HD 3000 and an i5 processor. (2520m). I have 4 GB of factory installed RAM and a 320 GB hard drive. I was hoping you guys could help me out. I have a retail copy of the Snow Leopard DVD. So what I did was burned iB00t and then used it to boot the retail DVD. It took like two full minutes but then I saw this: I tried going into verbose mode but same thing. I changed the mode to ACHI in BIOS and everything. I don't know whats going on. I also tried all the other flags like GraphicsEnabler=No and PCIRootUID=1 but to no avail. Can anyone help me out? Thanks! I think it might be the problem but I actually have all my other partitions still existing during this installation. I have 3 boot options that show up when I put in the ib00t cd. Windows 7, Lenovo Backup, and System Drive. Should I do some formatting or something? Sorry I'm so clueless. Hope someone could help:) EDIT: Do you guys think this is the problem? I'm using this DVD http://i46.tinypic.com/oi547p.jpg Link to comment Share on other sites More sharing options...
eep357 Posted July 8, 2012 Share Posted July 8, 2012 you cannot use that DVD, it will only work as a restore DVD with the exact mac model it came with. Not to mention it's also 4 years old and your using a newer CPU so no support for it on that version even if it was a full retail installer. 1 Link to comment Share on other sites More sharing options...
