petermartin Posted May 10, 2012 Share Posted May 10, 2012 Hi all, I'm trying to install Lion on my D620. I've created a myhack USB pen, but it fails when trying to boot into the myhack setup with the following error : mach 0 file has bad magic number Has anyone had this problem before?, I thought it may be something to do with AHCI in BIOS, but I can't seem to find anything to do with the SATA drive in BIOS. Its got a Intel 945 express chipset in. Anyone any ideas? Link to comment Share on other sites More sharing options...
petermartin Posted May 10, 2012 Author Share Posted May 10, 2012 I'm wondering if its a dodgy USB key that I used. I'm currently creating a different one. Link to comment Share on other sites More sharing options...

petermartin Posted May 10, 2012 Author Share Posted May 10, 2012 It was a dodgy USB key. The new one is currently installing OSX as we speak. Link to comment Share on other sites More sharing options...
petermartin Posted May 10, 2012 Author Share Posted May 10, 2012 The new USB key worked fine. The laptop is now working without any problems (that I've found anyway). The screen was a bit dark, but I used the EDP fix for that and it works fine. Thanks a lot for everyone's hard work getting to this point and making it so easy to follow the guides. Does anyone recommend a disk imaging application?, thought I'd make an image before I mess about more. I'm thinking something like Acronis True Image etc. Pete Link to comment Share on other sites More sharing options...
Administrators Syonagar Posted May 11, 2012 Administrators Share Posted May 11, 2012 Dear petermartin, I use disk utility to backup my os x partition. You need to create another partition or use external hard disk to write the image to. Cheers! Link to comment Share on other sites More sharing options...
