| | === Burn ISO image to USB and use dCore-usbinstall === |
| | The easiest way to install dCore to USB is to download a dCorePlus ISO. Below are some links to release candidate dCorePlus images: |

| | In Windows, there are utilities like Rufus and Unetbootin, the latter also available for linux. To install Unetbootin, add the following PPA if using Ubuntu: |
| | |
| | ppa:gezakovacs/ppa |
| | |
| | The simplest but least safe way to write an ISO to USB is using the dd command, but one must be absolute certain of their device name or data loss can occur. To find which drives on the system are USB, the below command will list them: |
| | |
| | <code> |
| | for I in `ls /dev/disk/by-id/ | grep usb`; do E=`readlink /dev/disk/by-id/"$I" | sed 's/[0-9]*//g' | sed "s/[./]//g"`; echo ""$E"_"$I"" ; done |
| | </code> |
| | |
| | If your USB device is /dev/sdb, then the following command will write the dCorePlus ISO to the USB: |
| | |
| | <code> |
| | dd if=dCorePlus-stretch64.iso of=/dev/sdb |
| | </code> |
| | |
| | Now you are ready for the initial boot of the USB to set up the final install. Reboot and set up internet connection. Then issue the following commands from a terminal window: |
| | |
| | <code> |
| | sce-import dCore-usbinstall |
| | sce-load dCore-usbinstall |
| | sudo dCore-usbinstall |
| | </code> |
| | |
| | The USB will not be mounted after booting with the ISO written to it, so the same USB can be used to install to. dCore-usbinstall will guide you through choices between x86 and x86_64, BIOS and UEFI, release and release candidates, and which dCore port you wish to install. It will create a bootable USB formatted with ext2 and the TCE directory will be located on the USB and used during future boots. |
| | |
| | The following below is a more hands-on method of installing dCore to USB. |
