I just finished building my computer, and I inserted the disk for Windows 7 Home Premium 64-bit, and when it began to boot up, it just gave me a black screen that said "Loading operating system...", and stayed that way for about 2 hours. I rebooted, tried changing the boot order setting in the BIOS so that the CD-ROM would load first, as well as some of the hard drive's settings, but it still won't proceed. This is the first time I've done all of this, is it normal for it to take hours to load an operating system in this manner? I'll provide more information if it's needed.
