Overview of Steps

1. Download the Omarine ISO.

3. Create a bootable USB.
4. Configure BIOS/UEFI.
5. Partition the disk.
6. Install Omarine.
7. Post-install setup and customization.

1. Download the Omarine ISO

Head over to the official website to grab the latest ISO:
https://www.omarine-linux.org/download.
Choose the Desktop or Server edition depending on your needs.

2. Verify the Checksum

Always verify the ISO to ensure integrity and authenticity:

3. Create a Bootable USB

On Linux, use dd (be very careful with dd—it’s like a nuclear submarine in the world of commands). Alternatively, use GUI tools like Etcher or Ventoy.

Using dd

• Identify your USB device: lsblk or sudo fdisk -l.
• Run:

  sudo dd if=omarine-xx.iso of=/dev/sdX bs=4M status=progress oflag=sync

  Replace /dev/sdX with your USB device.

4. Configure BIOS/UEFI

Restart your machine and press the key to enter BIOS/UEFI setup (common keys: F2, F12, Del, Esc).

• Enable or disable Secure Boot as needed. Omarine supports Secure Boot, but if you have trouble, temporarily disable it.
• Set USB drive as the first boot option.
• Save and exit.

5. Partitioning Scheme

Choose automatic for simplicity or manual for more control. Here’s a recommended manual layout for UEFI systems:

6. Installing Omarine

1. Boot from the USB installer.
2. Choose language and keyboard layout.
3. Select installation type (automatic or manual).
4. Configure your partitions if manual.
5. Set up a user account and password. Tip: avoid password123 unless you love trouble.
6. Install the base system (watch the progress bar like a hawk).
7. Install GRUB (the bootloader)—this step is crucial!

7. First Boot and Post-Install Setup

Congratulations! Reboot and remove the USB drive. You should land on the Omarine login screen. Now, let’s polish your shiny new OS:
