For General Users
Getting Technical
rEFInd
This very flexible product has three prerequisites:
- computer having modern, UEFI, firmware
- user having modicum of command line skill
- USB flash media, of at least 8 GB (USB3 preferred)
The product is available from: USB-image
- (caution) insert USB media and run "lsblk" to ascertain it's drive letter - sd(x)
- getting this wrong can result in the existing OS being overwritten
- (advisable) clear the USB drive - "dd if=/dev/zero of=/dev/sd<your drive USB letter> bs=1M count=8"
- unzip <refind...zip>
- dd if=refind-flashdrive-<.n.n.n>.img of=/dev/sd<your USB drive letter> bs=4M
- test boot this on any UEFI computer
- it should display pretty icons - including one for "shutdown"
- if not, have you disabled "CSM" & "secure-boot", in UEFI ? (essential)
- test boot this on any UEFI computer
- return the USB device to a booted Linux computer
- use GParted (preferably) to create additional partitions, one for each distribution ISO
- oversize each partition a little, to allow for later releases being larger
- format each partition to (preferably) "unformatted"
- give each partition both "label" and "name" relevant to the distro ISO to be placed there
- copy one disto ISO to its relevant partition:
- "dd if=<required-distro.iso> of=/dev/sd<your USB drive letter><partition-number> bs=4M"
- test boot this on any UEFI computer
- as required, copy additional ISO, to separate partitions
- for more detailed guides, see:
