Ryan Lang Posted February 27, 2012 Share Posted February 27, 2012 Somehow the partition map on one of my secondary drives got corrupted and now my computer won't get past the AHCI POST. If I clear the CMOS directly on the motherboard, I can get to the BIOS setup but not otherwise. If I switch to IDE, I can boot into my Lion install drive, but then the drives aren't detected. Can anyone think of a way for me to be able to wipe that drive somehow so I can boot? Thanks in advance.

LatinMcG Posted March 15, 2012 Share Posted March 15, 2012 boot gparted from usb or cd google "yumi usb". u can also use linux mint or so live to recover a few files if it works. first try reset bios defaults then set check settings u need. 1 Link to comment https://www.insanelymac.com/forum/topic/276483-wont-post-after-corrupting-partition-map/#findComment-1805895 Share on other sites More sharing options...
