cippolippo Posted December 29, 2012 Share Posted December 29, 2012 (edited) Hi All, I need some help to make Mountain Lion 10.8.2 boot from RAID1 Up to now I have done this (from a ML installed on a separate SATA disc): 1) format HD, then create RAID1 disk 2) launch DD script, set RAID as target and launch retail DVD install (option 1) 3) install starts and I select RAID1 volume … wait until it is done (20 min) 4) install boot loader Chameleon_2.0_RC5_r1278 (choose UseKernelCache Yes in options) 5) Problem: there is no Extra folder so DD script does not install kexts. Create one Manually on helper partitions 6) install kexts with DD script (selecting system as target) Here I started troubleshooting since I cannot boot from this RAID1 disk. Doing some search found these two threads interesting: 1) [GUIDE] LION on Software RAID0 fully working.. 2) [GUIDE] Chameleon 2 RAID - More complete tutorial I have tried following the recommendations in these two GUIDES (the first references the second). I have gotten to the point were: 1) If I try to boot the RAID1 disk, I get a boot0 done, boot1 error 2) If I try to boot a standard Mountain Lion off of a simple (non RAID) disk, selecting the RAID1 disk from chameleon GUI allows me to boot the RAID1 installed Mountain Lion. I think I am close to it, but still do not know how to do it. Any ideas? EDIT: please note that the RAID1 member partitions are on a GUID partition table (AFAIK I cannot make a RAID on MBR partition table on 10.8.2) Edited December 29, 2012 by cippolippo Link to comment Share on other sites More sharing options...
