Subject: [Release/Discussion] Grub4Dos Installer 1.1 (64-bit Version) – Making Legacy Booters Work on Modern Systems
Post Body:
Hi everyone,
I’ve seen a lot of confusion recently regarding the compatibility of Grub4Dos on modern 64-bit systems, specifically when trying to create multiboot USB drives on Windows 10 or Windows 11.
While the official Grub4Dos project is largely considered legacy software, many of us still rely on it for its incredible flexibility. I wanted to share a quick guide and resources regarding the Grub4Dos Installer 1.1 64-bit (often referred to as the "Grub4Dos Installer 1.1" package modified for x64 architecture).
1. "Failed to write MBR" / Access Denied
- Cause: Modern Windows (8/10/11) often locks drives or prevents direct sector writing.
- Fix: Ensure you ran the tool as Administrator. If that fails, disable "Fast Startup" in Windows to ensure the drive isn't hibernation-locked.
Part 5: Crafting the Perfect menu.lst for Version 1.1
The menu.lst is a plain text file using GRUB legacy syntax. Here is an optimized template for the 64-bit installer release.
# Grub4Dos 1.1 64-bit Sample Menu
color blue/green yellow/red white/magenta white/magenta
timeout 10
default 0
Example menu.lst (starter)
Use menu.lst to define boot entries. Example minimal configuration:
timeout 10
default 0
title Boot Windows
root (hd0,0)
chainloader +1
title Boot Linux kernel
kernel /vmlinuz root=/dev/sda2 ro
initrd /initrd.img
title Boot ISO image (loopback)
map /images/ubuntu.iso (hd32)
map --hook
chainloader (hd32)
Tips:
- Use device names carefully: Grub4Dos uses (hdX,Y) indexing starting from 0.
- The map (hd32) trick is useful to boot many ISOs; some ISOs need additional kernel params.
- Keep a verbose/debug entry for troubleshooting (add "debug" or "vbeinfo" commands).
7.4 Background images (64-bit compatible)
Place a 640x480 14-color XPM or a compressed message file in root. Reference it:
gfxmenu /message
splashimage /splash.xpm.gz
