This is my first build, everything has gone fine except installing windows 7. It will load up to asking where to install windows. I have the drivers on a flash drive, if I uncheck the 'hide drivers that are not compatible with hardware on this comp.' and select the driver a message pops up about how unsigned drivers can lead to improper something or other. Then it still won’t recognize the hard drive, even though I can see it when browse for the flash, and I can see it in bios. I have messed around with the RAID and SATA settings with no luck. Any help would be great.
Install W7 without connecting the flash drive, any drivers needed that Windows doesn't have, you can install after Windows is finished installing.
If it's not finding the sata drive, try setting it PATA/IDE compatability mode in bios.
If you still have a problem, tell if you are using full or update version on a blank drive or formatted drive with or without an OS.
