NTLDR Is Missing Help

double-check what you actually typed in. In particular, ensure double quotes instead of apostrophes, / instead of \, and curly braces instead of parentheses.
I also got an error on this command line and could not proceed further. I triple checked the entry characters as indicated above and it is exactly as instructed but still is not valid. There is sonething wrong with that command line.
There isn't anything wrong with it, it's been up there for five years come November. If you say an actual issue where you can say "xxx should be xyx" let us know. Blanket "something wrong" statements don't help.
