I have been trying to boot my XP Pro 32 bit in AHCI mode by implementing nLite, with numerous drivers and keep up coming up with the same problem. After burning my new CD, as soon as I boot CD, I get message: "No drives found", and the whole process is aborted. If I use nLite and prepare CD with Win XP OS only and no AHCI drivers slipstreamed onto CD, then my 500GB Seagate HDD is recognized. I read everything on the Index Page, and it appears my CD-ROM drive might be the problem, and I might have to purchase a USB Ext. CD-ROM drive to achieve my goal, however before I go out and spend unnecessary money, I would appreciate some feedback if this is in fact is the right diagnosis. My machine setup. Motherboard Intel DH77KC CPU Intel i7 3770 RAM: Single 4MB DDR3 1600Mhz HDD Seagate 6GB Sata 500MB - Connected to Sata 0 CD\DVD Writer LG Modisc - Model GH24NS95 - Connected to Sata 4 Operating System: Windows XP SP3 - 32bit
