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,http://sourceforge.net/projects/refind/files/0.12.0/refind-flashdrive-0.12.0.zip/download]

  • (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 of=/dev/sd<your 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)
  • 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 installed there
  • copy one disto ISO to its relevant partition:
  • "dd if=<required-distro.iso> of=/dev/sd<your drive USB letter><partition-number> bs=4M
    • test boot this on any UEFI computer
  • copy additional ISO, to separate partitions
