topherNOOB Posted December 11, 2008 Author Share Posted December 11, 2008 Try booting with external DVD drive. Thank you for your reply. I've tried installing JAS OSX86 10.5.4 from an external DVD-drive (through the USB) and still have the same problem. Installation starts up, asks me language, agree to terms and conditions, but when it asks me where I would like to install there are no drives to select from. When opening the Disk Utility the same thing occurs - there are no drives to format. No drives detected it seems. When looking at these drives in the BIOS setup both my hard drives are marked "RAID: " specific model drive (as I've listed above) I've done my best to look around other topics about RAID hard drives... or SATA hard drives and vaguely read about adding 'kexts' to my install, but I don't really understand it. Any help is again and always appreciated.

tbg10101 Posted December 15, 2008 Share Posted December 15, 2008 try making an 'af' partition on the drive. Boot into windows and resize an existing partition leaving however much space you want for your mac at the end of the drive. (if you are going to re-format the entire thing, just make the empty space 1gb) Open up the command line utility in windows and type these commands: diskpart select disk 0 create partition primary id=af this will create an af partition from that empty space. boot from the install disk. You should see the disk now. You will have to do some moving, resizing, and formatting but at least you can see the disk now. does this help?

Slice Posted December 15, 2008 Share Posted December 15, 2008 I think you need to set AHCI rather then RAID.

topherNOOB Posted December 16, 2008 Author Share Posted December 16, 2008 thanks for the advice. tbj10101: I'm worried about changing drive 0 because this is my vista drive. I took a look at changing the format to af (on disk 1 partition 1) but still I looked online and in my research it looks like i'm not able to format to af from vista. Is that true? I just to want to format a drive unnecessarily. Let me know. thank you for your help Slice: I'm not very knowledgeable about how this is setup exactly. In looking online it seems there is a difference between a software or a hardware raid setup. I'm not sure if mine is hardware or not. Here is what I know. That when I go into my alienware bios it lists the drives as RAID: ******* or IDE: ********. My two hard drives are listed under raid. But my bios also has a "Raid utitility" in which it asks if I want to mirror the drives, or make them an array. In this menu I can see that they drives are separate and that their type is SATA. So I'm curious if I'm getting difficulty because i have a RAID controller? (a hardware raid) and is this a problem? In this Raid utitility there doesn't seem to be a place to change the type of harddrive. So my bottomline question to you is. How do I change from a RAID to AHCI? thank you all for your help.
