| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | The installer lacks admin privileges or antivirus is blocking raw disk access. | Run as Administrator. Disable real-time protection temporarily. | | Grub4DOS boots to a grub> prompt, no menu | menu.lst is missing, misspelled, or not in the root. | Copy menu.lst to the root of the boot drive. Ensure it is not menu.lst.txt . | | Windows boots directly, no Grub4DOS menu | The installer wrote to the wrong MBR or a Windows bootloader overwrote it. | Re-run Installer 1.1, verify disk selection. Use "BootICE" to view MBR contents. | | "Error 60: File for drive emulation must be in one contiguous disk area" | The ISO file is fragmented. | Defragment the drive or use map --mem instead of just map . | | Installer crashes on Windows 10 | Version 1.1 uses deprecated Windows API calls. | Use Windows 7 compatibility mode. Or switch to the command-line bootlace64.exe from newer Grub4DOS builds. | Grub4DOS Installer 1.1 vs. Modern Alternatives How does this legacy installer stack up against contemporary tools? title MemTest86+ map /memtest
