In this article you will learn to build C apps on Ubuntu. However, since all of the topics are covered already and I am just skimming through the snippets and small portions of the data that I can share, this is another post in the series before I continue to write a guide for this, in a compiled form. In this post, I am going to talk about cryptographic support provided in Mono itself, for Ubuntu. However, you can always write your own compiled modules that run the cryptographic services and you can also write your own modules that represent the procedures and steps shown in the certified algorithms for cryptography.

Before starting the installation, we need to prepare the harddisk. Start up GParted as this is the easiest to work with, if you feel adventurous it can be done in parted or fdisk as well. Start by creating a new partition table if needed if you want to start over or the disk is empty. Of course this will destory any data already on the disk, you may want to resize any existing partitions Windows for instance instead.

I am trying to get an encrypted Manjaro install dual booting with Windows 10, and trying to use manually partitioning to do this. I've tried searching for an answer but couldn't find one. The problem is that when turning on the computer, there is a password prompt before GRUB even shows, and another password prompt when I select Manjaro. Is there a way to make it so the only time it will ask for a password is when I select to boot Manjaro from GRUB, making it so the password is not needed if I boot into Windows?
I apologize, but in my opinion you admit the mistake. I can defend my position. Write to me in PM, we'll talk.
