If it does not help, reformat the outer volume again and copy less files/folders to its root
folder than you did last time. If it does not help, keep reformatting and decreasing the
number of files/folders in the root folder. If this is unacceptable or if it does not help,
reformat the outer volume and select a larger cluster size. If it does not help, keep
reformatting and increasing the cluster size, until the problem is solved. Alternatively, try
creating a hidden volume within an NTFS volume.
PROBLEM:
One of the following problems occurs:
 A VeraCrypt volume cannot be mounted.
 NTFS VeraCrypt volumes cannot be created.
In addition, the following error may be reported: "The process cannot access the file because it is
being used by another process."
PROBABLE CAUSE:
This is probably caused by an interfering application. Note that this is not a bug in VeraCrypt. The
operating system reports to VeraCrypt that the device is locked for an exclusive access by an
application (so VeraCrypt is not allowed to access it).
POSSIBLE SOLUTION:
It usually helps to disable or uninstall the interfering application, which is usually an anti-virus utility,
a disk management application, etc.
PROBLEM:
In the VeraCrypt Boot Loader screen, I’m trying to type my password and/or pressing other keys
but the VeraCrypt boot loader is not responding.
PROBABLE CAUSE:
You have a USB keyboard (not a PS/2 keyboard) and pre-boot support for USB keyboards is
disabled in your BIOS settings.
POSSIBLE SOLUTION:
You need to enable pre-boot support for USB keyboards in your BIOS settings. To do so, follow
the below steps:
Restart your computer, press F2 or Delete (as soon as you see a BIOS start-up screen), and wait
until a BIOS configuration screen appears. If no BIOS configuration screen appears, restart (reset)
the computer again and start pressing F2 or Delete repeatedly as soon as you restart (reset) the
computer. When a BIOS configuration screen appears, enable pre-boot support for USB
keyboards. This can typically be done by selecting: Advanced > ‘USB Configuration’ > ‘Legacy
USB Support’ (or ‘USB Legacy’) > Enabled. (Note that the word ‘legacy’ is in fact misleading,
because pre-boot components of modern versions of MS Windows require this option to be
enabled to allow user interaction/control.) Then save the BIOS settings (typically by pressing F10)
