ey how do I know which mnt/hdal im using? he says there is loads of combinations, and how do I find out mine? please help 
NB – i’d suggest keeping any passwords you change for the BT4-Final account/s themselves to under 8 characters as is warned, cause i changed it to over 8 and couldn’t get back in! – blanking out shadow, passwd, etc in the usual manner didn’t work, so it must be hardened to avoid that.
yes there is many ways of mounting the hard drive i just posted the way i did it to help people it will save you the time replying to people that dont now.. great tutorial anyway…
@palmster187 I read all the comments, but I am also very busy, so rarely to I get to reply soon.However, if I receive a message or email, you are much more likely to receive a response faster. Regarding your comment about how you mounted the Windows Partition, there are many ways to do it, I just go with the most simple and common one, so that If I’m not clear enough, people may be able to look online for other tutorials and see how they are the same, and understand it better. Hope this helps
hey man i just posted a few comments on this vid cause the owner dosent seem to be helping alot best thing to do to see witch is yours is to check in the mnt folder in system menu home folder root folder mnt if its not ther you need to munt your hard drive this is how i did it system /settings system administration/disk and filesystem-mountpoint editor….click new set the mount point where you want anymore help pm me or reply to comment
great tutorial ery well explained apart from that you have to mount the hard drive i did this by bootin backtrack off a usb flash drive mounting the c drive to the /mnt directory so my command was just chnptw -i /mnt/Windows/System32/config/SAM ……again very good tutorial this will help alot of people i just did it for a twst to see if it worked
it says somthing like “dev sda” blablabla d;
- but when i try to write the code in the “chntpw box” it just says no such diretory, or something in that sens?
can you help me?d;
hda1 is the first IDE connected hard drive on the system. sda1 is the first SATA connected hard drive and so on…
Since backtrack is very similar to ubuntu, Im assuming you can use the command “sudo fdisk -l” to see the names of the hard disks on the system
to do this crack… do I have to install?
If “Yes” … On install do I have to create a partition in Hard Disk?
hey dude, when you say “hda1″ or those things, is that the name of your harddrive?
couse mine is called ACER (C:) – so is it /mnt/ACER/… ? or what? 
hi
I have a virtual group of computers running on server 2003…. on the same network i have back track as well will i be able to change the password… i have set up all the users by active directory…
