Preparing a Chapeau USB disk on Linux & Unix
A USB disk capacity of at least 4GB is required to create a Chapeau bootable USB disk.
When you perform this procedure any data on the USB flash drive is destroyed with no warning.
Also make sure that you specify the correct disk device, and make sure that this flash drive does not contain any data that you want to keep.
Writing Chapeau to your USB disk with dd
- Plug in your USB flash drive.
Find the flash drive’s device name. If the media has a volume name, use it to look up the device name in /dev/disk/by-label, or use the findfs command:
- Switch to the root user either with sudo, entering your password when prompted:
Shell1sudo su -
- Then use the dd command to write the boot ISO image to the USB device:
Shell1dd if=path/image_name.iso of=/dev/device bs=block size
Ensure you specify the device name (such as sdc), not the partition name (such as sdc1).
The bs option specifies the block size; it can be omitted, but specifying it will speed up the process. For example:
Shell1dd if=~/Downloads/Chapeau_21.1.2_x86_64.iso of=/dev/sdd bs=512k
