*Step-by-Step Installation:*

#### 1. *Create a New Virtual Machine in VirtualBox:*
Open **VirtualBox**.
Click *New* to create a new virtual machine.
*Name* the VM (e.g., “RHEL 9”), set the *Type* to “Linux,” and the *Version* to “Red Hat (64-bit).”
Click **Next**.

#### 2. *Allocate Memory (RAM):*
Allocate at least *2GB of RAM* (4GB or more is recommended for better performance).
Click **Next**.

#### 3. *Create a Virtual Hard Disk:*
Choose *Create a virtual hard disk now* and click **Create**.
Select *VDI (VirtualBox Disk Image)* as the disk file type and click **Next**.
Choose *Dynamically allocated* (which allows the virtual disk to grow as needed) and click **Next**.
Set the virtual disk size to at least *20GB* (more if needed) and click **Create**.

#### 4. *Configure Virtual Machine Settings:*
Select your RHEL 9 VM in VirtualBox and click **Settings**.
Under *System**, make sure the **Floppy* option is unchecked in the Boot Order.
Under *Storage**, click the **empty disk* under “Controller: IDE,” then click the disk icon on the right and choose the *RHEL 9 ISO* file you downloaded earlier.

#### 5. *Start the Virtual Machine:*
Click *Start* to begin the installation process.
RHEL 9 should boot from the ISO image.

#### 6. *Install RHEL 9:*

#### 7. *Complete the Installation:*
The installation process will take some time. Once it’s complete, the system will prompt you to reboot.
