Restart your computer. If installed to MBR, you'll see the GRUB4DOS menu before Windows loads. Use the arrow keys to select an OS. grub4dos installer 1.1 64 bit
If you try to run the classic grubinst.exe on a 64-bit version of Windows, you likely get an error like: | Feature | Grub4dos 1
"The version of this file is not compatible with the version of Windows you're running..." Restart your computer
This happens because the original installer is a 32-bit GUI/CLI application that sometimes struggles with 64-bit system drivers or simply isn't recognized correctly by modern Windows security features.
Note: Exact commands depend on the vendor-provided installer. Always read included docs.
Older Grub4Dos versions struggled with large NTFS volumes. Version 1.1 includes improved NTFS driver (64-bit clean). Use:
map --mem /path/to/large.iso (hd32)
map --hook
chainloader (hd32)
