How to perform "chkdsk /r" ouside windows

If windows is not loading and plugging the HDD into a working pc but the data inside the HDD is still not detected, perform these steps:
1. Boot to cd (it's like installing the windows again)
2. Press R (for recovery console, instead of "Enter" where installation of windows will take place)
3. On the C:\> prompt, type "chkdsk /r"
4. Wait until the check disk utility finishes.

Inside windows:
1. Go to run, type cmd
2. On the C:\> prompt, type chkdsk /r

Good luck!
