Partitioning Hard Disk for Installing Linux OS side by Windows

Many library professionals who work in the Linux operating system environment are/not aware of installing a fresh Linux OS (Debian, Ubuntu or their derivates) in a new system and that is pretty much easy, but installing both Linux OS and Windows OS side by side ( Dual Boot ) may be unfamiliar. If you wish to install any Linux OS in a system that has already windows OS, you have the following methods by which you can start using any Linux based operating system.

1. Use Linux inside Windows in a virtual machine: 

This runs a Linux OS like any other application within Windows. This is also one of the safest ways to get a feel of Linux. However, this will utilize your system resources and if you have less than 4Gb of RAM, I won’t advise using it extensively.

2. Use a live version of Linux: 

In this method, you put Linux on a USB or DVD and you boot from it. This is usually slow and your changes done to the Linux system are (normally) not saved. This is particularly useful if you just want to see what Linux feels like.

3. Remove Windows and Install Linux: 

If you have backed up your data and have a recovery or installation disk of Windows ready with you or if you are determined that you are not going back to Windows, you can remove Windows completely and use only Linux.

4. Install Linux alongside Windows: 

This method is called dual-booting Linux with Windows. Here, you install Linux on a system that already has Windows. And when your system powers up, you can choose if you want to use Windows or Linux. This involves touching the disk partition and sometimes boot order. Absolute beginners often find it complicated but this is the best way to use Linux and Windows together in one system. 

Partitioning Methode of Hard Disk

  1. Guided - Use the largest continuous free space (for beginners)
  2. Guided - Use entire disk
  3. Guided - Use entire disk and set up LVM
  4. Guided - Use entire disk and set up encrypted LVM
  5. Manual / Something else (Creating manual partitions)
Create partitions manually

First of all, search Diskmgmt.msc in windows and create a free space of 100 GB. from this free space create partitions for Linux 

1536 MB    (1.5 GB)    for /boot
1024 MB    (1 GB)       for ESP  - EFI (Extensible Firmware Interface) System Partition -
15360 MB  (15 GB)     for swap
51200 MB  (50 GB)     for (root user)
30720 MB  (30 GB)     for /home 
160 MB ( will become FREE SPACE )
  
Now choose / install Linux OS into this partition.
