Create Bootable USB

Once we have the ISO file, the next step is to flash the ISO image onto a USB stick to make it bootable. Follow the instructions below:

Methods

Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
With Ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.

First, follow the instructions here: How to make bootable USB drive with Ventoy
Next, we will copy and paste the ISO file into the Ventoy folder like this:
Once everything is done, we will remove the USB drive, and now you have a bootable USB drive to install RengeOS, which supports both UEFI and Legacy BIOS modes.

If you’re already using Linux, you can create an RengeOS bootable USB with dd. dd creates both BIOS and UEFI bootable USB Follow the steps below to create a bootable USB with dd :

Open a terminal and run lsblk to get the USB info. In my case, it’s /dev/sda.

[rengeos@host ~]$ lsblk

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda           8:0    1  14.7G  0 disk
├─sda1        8:1    1  14.6G  0 part
└─sda2        8:2    1    32M  0 part
zram0       253:0    0   2.8G  0 disk [SWAP]
nvme0n1     259:0    0 238.5G  0 disk
...

After finding your USB device, Run dd to flash the ISO on USB.

sudo dd bs=4M if=path/to/rengeos.iso of=/dev/sdX status=progress oflag=sync

Make sure you replace path/to/rengeos.iso with the RengeOS ISO path and sdX with your USB device.
This will create a bootable RengeOS USB for both BIOS and UEFI.
