One of the fixes for the "NTLDR is missing" error message during system boot relies on replacing the corrupt NTLDR file with the same file copied from another Windows host using the same operating system (Windows XP), or restoring it from the Windows XP installation CD. Copying the NTLDR file manually requires access to the command-line interface which can be found as one of the options available in the Advanced Boot Options menu displayed after pressing the F8 key during system boot. After gaining access to the CLI, the NTLDR file can be restored with the COPY command from an external storage device (e.g. USB flash drive) to the root folder (typically C:\) of the drive containing the corrupt version of the file. True or False

The term "Live CD" typically refers to a compact disc (although other types of media such as DVD or USB can also be used to offer similar functionality) with a fully operational bootable Linux operating system distribution (the term is also used with reference to other OSs) which is run in the computer's memory thus eliminating the need for its installation on the hard drive. Live CDs can be used as an OS installation media, but also provide a convenient way for testing a given distro before installation as well as means for troubleshooting various OS-related problems. True or False
