According to your description, your computer has just been upgraded, which is changed from legacy boot mode to UEFI boot mode. It's the reason that you cannot boot your Windows system on the MBR disk. The built-in tool of Windows, such as Dispart and Disk Management, will wipe all your data on this disk. Therefore, do a full backup before using them, or you will lose all your important data, and the process is irreversible. Don't worry.
