Running Redox OS on Vultr

redox-on-vultr.md

This is tested against Redox OS daily image of Jan 31, 2026.

• Booted from GRUB (dual boot with Linux)
• Mouse, Keyboard, Display working smoothly
• Disk does not work, need to boot to live mode
• Networking does not work
• The bootloader VGA is corrupted over VNC, need to just blindly hit enter after booting from GRUB.

Steps in a nutshell

• Generate new image from Redox OS Installer
  • redox_installer redox.img -c desktop.toml --write-bootloader=bootx64.efi --skip-partition --live
• Boot over GParted Latest Live CD
• Shrink the root partition disk (hopefully you use ext4 already)
  • Add single 256 MB FAT32 partition, mark it as msp, boot
  • Add other partition, unpartitioned
• Boot back into Linux to apply our filesystems
  • Let's say there's /dev/vda3 for EFI partition, /dev/vda4 for RedoxFS partition:
  • sudo dd redox.img if=redox.img of=/dev/vda4 bs=4M status=progress
  • Mount the bootloader partition, sudo mount /dev/vda3 /mnt, copy over the EFI:
  • mkdir -p /mnt/efi/redox then cp bootx64.efi /mnt/efi/redox/
• Reboot to grub, then try loading it manually in the terminal
  • chainloader (hd0,gpt3)/efi/redox/bootx64.efi then boot
  • If it works, you can add this to boot menu later
