I changed my permission and Windows would no longer boot up. I came across this forum which I used and it worked! There is a trick to make this go faster. You can run multiple commands at one time by separating your commands with &&. For example[code]icacls Windows /t /c /grant SYSTEM:(M) && icacls Windows /t /c /grant SYSTEM:(F)[/code]
Notice the space after the first one and no space before starting the first one. I don't know if it'll help anybody else but this trick saved me a lot of time sitting around waiting to enter the next command.
Apparently the : ( symbols with out the space makes a frown face. In my example please refer to the first to commands.
