GrandMstrBud Posted October 22, 2012 Share Posted October 22, 2012 Followed this guide after creating a 10.8 USB install drive and I can not get it to see the internal hard drave. I put it to legacy also and still nothing. http://wiki.osx86project.org/wiki/index.php/HCL_10.8.0/Desktops#Dell_Optiplex_745 I tried it with and without the IOATAFamily.kext in the Extras folder and I am booting with the -x GraphicsEnabler=No and the bios is updated.

eep357 Posted October 22, 2012 Share Posted October 22, 2012 For sata drives, try this in System/Library/Extensions NOT in /Extra/Extensions, make sure SATA is in AHCI mode or if no AHCI option in Dell bios, use RAID mode instead. Boot with -f added to any other bootflags AHCI_Extended_Injector.kext.zip Link to comment https://www.insanelymac.com/forum/topic/283818-108-on-dell-optiplex-745-no-hard-drives/#findComment-1862424 Share on other sites More sharing options...

Boot with -f added to any other bootflags Thanks I was able to get it I don't think the BIOS was sticking with the legacy mode but now at the end it gets about 2 minutes left and it says "Install Failed" "The installer encountered an error that caused the installation to fail." Not sure what I'm doing wrong I was hoping to get it to work on this. EDIT: I redid the USB install boot drive and now I can't see the drive again.

I've got Dell 745 ML install on an external usb drive, I had the internal drives working using normal in the bios, they seem to have dropped off again today. The dell 755 has no problems at all.

GrandMstrBud Posted October 25, 2012 Author Share Posted October 25, 2012 Legacy or not it will not see the hard drive. I just don't get it. What bios should I use will that make a difference or another bootloader?

eep357 Posted October 25, 2012 Share Posted October 25, 2012 What are the specs on your 745? Looking at specs for Dell 745 on dell's site, although there's a few configurations, didn't see any with core 2 duo or newer CPU, only core duo which would not support ML. -nevermind, see some core 2 duo's, still specs and southbridge chipset would be helpful Link to comment https://www.insanelymac.com/forum/topic/283818-108-on-dell-optiplex-745-no-hard-drives/#findComment-1863039 Share on other sites More sharing options...
