Hi all, Mac user since 5 years i tried to install Lion on my DELL E6500. Install succeeded on an external usb disk but when i try to install it on my internal HD i can not see it in Disk Utiity. BIOS is set to AHCI as recommend. Tried to partition internal HD wit Gparted but no success. When I try an itakos SL version then my HD is visible in Disk Utility! After HD format with iFail , tried to reinstall with MyHack but again no internal HDD visible ! Any idea or suggestion is welcome ! Thanks in advance for your help;
