I'm getting closer and closer, but still need some clarification. Please help once more. I have a genuine version of XP 32 bit (with the MS XP Disk) installed on an Intel DX58SO MB, an i7 chipset and Insyde BIOS /ACPI 2.0 . SLIC Toolkit shows a valid PKey but in the Cert: block I get: No OEM Certificate found !(Run as Adminstrator). I'm also showing: Dump Error ! (SLIC Table Not found ! ) What I want to do is partition my drive and install Win 7 Ultimate x64 on the new partition using Daz's loader to activate, while keeping XP x86 on the "C" drive. I read here that someone tried something similar with Vista and it deactivated Vista. Will what I want to do work? I would like to have both XP & 7 available to ease the transfer of programs from XP to 7 if possible. I have an awful lot of "stuff" on my machine and getting it to work as it does now took a loooonngg time! If someone has a better way of getting all my settings into 7, I'm all ears, but please remember that I'm not a computer guru. Thanks.
