Hi there! I'm having an issue with my PC regarding dual-boot Windows 8.1 and Windows XP. I had as my primairly boot OS Windows 8.1 Pro with Media Center (x64) and I decided to dual boot with Windows XP Professional SP3 (x86). The thing is, yesterday I successfully installed and get to work Windows XP but now I can't boot into Windows 8.1! Windows 8.1 is still on my hard drive with all it's core files, my programs, etc. I don't want to reinstall Windows 8.1 on my PC, I just want (if possible) to regain access to this OS without losing programs or the entire OS. Thanks in anticipation!
