Yesterday, a guy suddenly asked me that how he can hide the Ubuntu partition on Windows 8. I told him that Ubuntu or Linux partition is not readable by Windows and it got already hidden when you install Ubuntu in parallel drive to Windows. So he asked me his next question, how he can hide Windows partition in parallel with Windows itself. The answer to his query, led me to write this article.
There are various reasons why you want to hide your specified drives and in this article, I’ll show you the way to hide a particular drive or all drives or pair of drives. Hiding a drive will led you the drive inaccessible from Run dialog, Command Prompt etc. The method involves modification of registry, so its already recommended for you to create a System Restore point before proceeding.
Now, here is how to:
How To Show Or Hide Drives In Windows 10/8/7
Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point first.
1. Press 
+ R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.
2. Navigate here:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
3. In the right pane of this location, create a new DWORD value named as NoDrives using Right click -> New -> DWORD. Double click on this newly created DWORD to modify its Value data:
