.The first thing you need to understand is that Linux is very different from Windows.
|
|
****
|
|
- The filesystem is different
|
|
- installing software is different
|
|
- security is different
|
|
- installion is different
|
|
- etc

== Intro
|
|
|
|
[NOTE]
|
|
====
|
|
You must be open to learning new techniques and habits.
|
|
|
|
Dual-boot requires good backups from the start. *You never know when a Windows update will wipe all your partitions :-)*
|
|
|
|
Reinstalling Ubuntu is very easy - About windows I wouldn't be that sure... :-)

|
|
|

|
== Install
|
|
|
|
=== Auto Install Ubuntu
|
|
|
|
This is the part that makes *installation alongside Windows 10* different from a normal installation.
|
|
|
|
The Ubuntu installer automatically detects that we have a pre-existing Windows 10 installation on our system,
|
|
|
|
TIP: Select "Install Ubuntu alongside Windows 10" option and click on continue.
|
|
|
|
Thats all!
|
|
|
|
|
|
|
|
Is the "Install Ubuntu alongside Windows 10" option missing?
|
|
|
|
|
|
.Please note that in the following circumstances the Ubuntu 20.04 installation option "Install Ubuntu alongside Windows 10" may be missing,
|
|
[NOTE]
|
|
====
|
|
- if your Windows 10 installation "is not correctly shutdown"
|
|
- is hibernating,
|
|
- your disk has corrupted partition which needs repair,
|
|
- your disk has not enough free disk space left for creating/resizing partitions
|
|
- uses Dynamic Disk or the file system contains uncontrollable file fragmentation
|
