I am Krunal K. Doshi from India having 10+ year of experience in IT field.
I understand from description that you would like to build a bootable USB flash drive for Windows 10 specifically using DiskCryptor. Process is already mentioned on the page, link you provided, so I would like to know what issue you are facing? Also, is it necessary to you use DiskCryptor or we can use some other software?
Looking forward to your reply.
