How do you delete ntldr?

GodlyGreek · 25-October-07, 10:54 AM

I know it's a weird question, but I need to know how to delete ntldr using a CLI command for my windows class. (it's for troubleshooting purposes) I've tried searching it on google, but everything just explains how to fix a missing ntldr.

Thanks.

I hate helping people cheat, but here's a hint:

You don't delete NTLDR. You change the pointer from the current NTLDR to an invalid location.

You gotta find the pointer. I ain't helping you that much!!! Ya gotta learn!!!

GodlyGreek · 25-October-07, 11:11 AM

hmmm, what do you mean? Just change the location of ntldr?

I am so confused lol....TELL ME!!! haha.

How does the operating system know where to look for the NTLDR file?

GodlyGreek · 25-October-07, 11:26 AM

MBR finds the boot sector, and the boot sector finds ntdlr in the root of the system partition.

Joose · 25-October-07, 11:29 AM

What if you have more than 1 operating system (or instance) installed on the computer? How does it know which NTLDR to use?

GodlyGreek · 25-October-07, 11:30 AM

I don't know

My confusion here is how is making that drive unbootable a troubleshooting technique? Just feels counter intuitive to me . . . Unless this ASSUMES multiple OS's . . . And then it makes sense.

Joose · 25-October-07, 11:37 AM

the same principle holds true if there's one OS or there's 5...the pointers are all in the same place. In a file. Editable by any editor, including a CLI-based editor like "edit".

Or you could also use the cacls command in your quest to find operating system non-bootage.

By the way, GodlyGreek, you left out a step in your post #5.

If I just tell you the answer, you're going to forget it when it comes time to actually troubleshoot a real problem. By thinking about it, you're better able to understand why what you do will break the OS, then be able to troubleshoot what your other classmates have done to their test systems.

You will come across this problem, (likely faily frequently) in the real world, so understanding how to fix it (or how to break it) will come in very handy.

I know it's stupid. But, gotta do what the prof says lol. It's a windows troubleshooting assignment. One question is how do you delete ntldr using CLI. And another similar one is how do you delete ntdetect.com using CLI.

He wants us to know how to do it because then he wants us to actually do it in class to fix missing ntdlr and so on... ugh...lol

Twizted · 25-October-07, 11:39 AM

sigh..... lol

And what class are you taking? Cause it may be a little advanced at this point...

I know this question is a stretch but lol what would the command look like EDIT ?????

They're likely 'breaking' their machine so a classmate can come by and fix it...thereby ingraining the troubleshooting technique. If you know how to break it, you'll definitely know how to fix it.

Oh, I didnt mean it was an advanced class... I was thinking just a lil to advanced for you to handle.... I'm not trying to be mean but he gave you some pretty telling clues and even so, I done a quick 5 second search on google and found answers (using info joose stated in his comments with the initial question) It really is not that hard

It's sad at this point that I dont know how to break it (software wise) lmao.

drougnor · 25-October-07, 11:46 AM

I'll drop this one hint . . . you are looking at it wrong if you are seeing that it's ONE command to delete the ntldr file. You need to look at it in several stages.

And that's if you are looking SPECIFICALLY to delete it.

So, go do some reading on basic Windows command line commands and see if you can put the pieces together.

Joose · 25-October-07, 11:50 AM

OK.
Sigh...

investigate the following file: boot.ini
investigate the following command: cacls
investigate the following command: edit

Windows won't let you do anything to the ntldr file itself, while windows is running. Why is that? look into that too. Ya gotta think, man!
