I purchased Windows 7 upgrade and I formatted my hard disk. I don't know where my Windows XP disk is, and I don't know where my Motherboard Driver Disk is.
When I try to load Windows 7, it can't find the Hard Drive. What do I do???
What motherboard do you have? Are you running a RAID controller?
Sounds like Windows 7 does not detect your SATA controller on your motherboard, so you will need to download the latest SATA controller drives from the motherboard's website.
When downloaded, unzip and save to a USB, start Windows 7 installation again. When you need to specify a hard drive, select load driver and select the driver on the USB.
