    I have a USB MultiBoot that boot different operating systems. I use only one FAT32 partition to have compatibility even with UEFI Now I wanted to split into 2 partitions, one NTFS and one FAT32 The problem is that I can not direct the startup for the installation of operating systems

    For example, I use this command line in Grub2:

    Code:
    if [ "${grub_platform}" == "efi" ]; then
       if [ "${grub_cpu}" == "x86_64" ]; then
       menuentry "Windows 7 SP1 AIO (x64)" --class w7 {
           insmod part_msdos
           insmod chain
           chainloader /efi/bmgr/W7X/BMGRx64.efi
       }
       fi
    fi
    if [ "${grub_platform}" == "pc" ]; then
       menuentry "Windows 7 SP1 AIO (x86)" --class w7 {
           search --file /boot/bmgr/W7 --set=root
           insmod ntldr
           ntldr /boot/bmgr/W7
       }
       menuentry "Windows 7 SP1 AIO (x64)" --class w7 {
           search --file /boot/bmgr/W7X --set=root
           insmod ntldr
           ntldr /boot/bmgr/W7X
       }
    fi
    
    instead in Grub4dos simply

    Code:
    title Windows 7 SP1 AIO (x86)
    chainloader /boot/bmgr/W7
    
    Now if I had to tell him what partition needs to start, what should I add ?! I tried with the "set root=(hd0,1)" but I can not ... I also tried to put NTFS / FAT32 or interted but nothing

    Thank you
