SO, no, I don't have 2 versions of windows 7 installed in a dual boot, but here's the back story on why it appears that way. I had vista 32 bit home premium installed, and decide to dual boot into the Windows 7 RC. That all went well, i created a new partition and installed windows 7 home premium 32 bit onto it. Recently, I found out that through school, I now have access to the full release version of windows 7 professional. I'd been wanting to make the switch to 64 bit, so that was the version I got. After backing up everything I needed to, I simply deleted the Windows 7 partition, and resized the one remaining partition to take the full size of the disk. I then ran the windows 7 pro 64 bit disc, and installed it. Everything on the install works beautifully. However, it now gives me the option to either boot in windows 7 (new one) or windows 7 (old one), despite the old windows 7 not being there. I'm told you can make it so it doesn't show you your boot options and will default load into the new windows 7, but is there a way to actually fix it so the bios doesn't even see the old windows 7 in the boot sector? Thanks!
