I have Windows 8 Pro in C drive. Installed Windows 8.1 Preview using USB. After entering the Key & the installation process. The computer restarted as per the command. I entered the Boot mode by clicking DEL key & change back the boot priority to Hard drive & restarted. The computer is going directly into the Windows 8 Pro lock screen. Its is not showing or asking for Two OS selection... What should I do.??
"Installing from the Store will upgrade the existing Windows 8 OS on that partition to Windows 8.1 Preview," reads Microsoft's Q&A. "You will not be given the opportunity to select another partition, so you would need to already have a dual boot system installed in order to install Windows 8.1 Preview as a dual boot through Windows Store."
Did you have a dual boot already setup or just Win 8 Pro only?
