Boot from extended partition

[D-EVE-R]

hello, is there any way to boot VDisk from the /dev/sdb6 partition? I have tried playing with the "ventoy_grub.cfg" but with no success. actually, I have no idea what to put in the set line.

Please do a test:

1. For example, you put abcd.vdi.vtoy to the root of /dev/sdb6 (no parent directory)
2. When you boot into Ventoy's boot menu. Press c to enter shell and run

ls
search -n -f "/abcd.vdi.vtoy"

and give me the result

it says hd0,msdos6

That's OK.

Save the following content to ventoy_grub.cfg and put the file to ventoy directory in the 1st partition.

menuentry "Boot My Linux VHD" {    
    set my_vdisk_path="/abcd.vdi.vtoy"
    
    if search -n -s vdiskhd -f "$my_vdisk_path"; then
        vtoyboot_common_func "($vdiskhd)$my_vdisk_path"
    else
        echo "$my_vdisk_path not found"
    fi
}

Boot to Ventoy and F6--->Boot My Linux VHD

Thanks for your quick and helpful reply.

Does it work?

[D-EVE-R]

Yes, it does, thank you. I was before adding the paths for the VHD file, thas why it wasn't working. Before:

   menuentry "Boot My Linux VHD" {    
       set my_vdisk_path="(hd0,6)/abcd.vdi.vtoy"

       if search -n -s vdiskhd -f "$my_vdisk_path"; then
           vtoyboot_common_func "($vdiskhd)$my_vdisk_path"
       else
           echo "$my_vdisk_path not found"
       fi
   }

After:

   menuentry "Boot My Linux VHD" {    
       set my_vdisk_path="/abcd.vdi.vtoy"

       if search -n -s vdiskhd -f "$my_vdisk_path"; then
           vtoyboot_common_func "($vdiskhd)$my_vdisk_path"
       else
           echo "$my_vdisk_path not found"
       fi
   }

Update: It does get stuck at loading, never launches, no matter how much I keep it.
