No.
Why didn't Windows NT replace DOS. as originally planned?
No. Windows NT had it's own kernel and bootloader.

Pretty much yes, up until Windows XP there were versions of Windows that ran "on top" of MS-DOS, but XP (based on Windows NT) removed that requirement. MS-DOS sort of lives on as the Windows command prompt which supports most of the MS-DOS commands and allows people to run MS-DOS programs.
NT does have backward compatibility. You can use every NT program on every NT based platform. DOS platforms however are completely different.
Windows NT (New Technology) was released as a 32-bit operating system in 1993 with the goal of replacing the aging MS-DOS (Microsoft Disk Operating System) as the primary operating system for personal computers. However, it did not fully replace DOS for several reasons: Compatibility: Windows NT was not fully compatible with older software and hardware that was designed for MS-DOS, making it difficult for businesses and individuals to switch. Market share: MS-DOS had a significant market share and was widely used, making it difficult for Microsoft to convince users to switch to the new system. Cost: Windows NT was more expensive than MS-DOS, which was a barrier for many individuals and businesses. Performance: Windows NT was designed as a more secure and robust operating system, but it was also slower and required more resources than MS-DOS. As a result, MS-DOS remained in use for several years after the release of Windows NT, and Windows NT evolved into what is now known as Windows 10, which is the current version of the Windows operating system.

You don't. hal.dll is a Windows NT file; it isn't usable or needed in MS-DOS.
