HP dv6227cl

[J2N4Ever]

I'm having a little issue with Zeph's Leo 10.5.2 Rev. 1

I have an HP Pavilion dv6227cl currently running Vista Home Premium. I can get all the way to the Installer no problem. I then open Disk Utility to partition and format my drive to HFS+ (Journaled) and my hard drive isn't in the list of drives available.

System Specs:
AMD Turion x2 TL-50(MMX, 3DNow!, SSE, SSE2, SSE3, x86-64)
Graphics Chipset: nVidia GeForce 6150
Southbridge: nForce410/420 MCP
RAM: 1GB
HDD: Toshiba MK1237GSX SCSI Disk Drive (What it says in Windows)
HDD has Two Partitions: OS / RESTORE. Both are NTFS.
DVD Writer: Optiarc DVD-RW AD-7530A

If you need anymore information to help, let me know!

Regards,
Johnny
