Steve2926, have you tried booting successfully with Medicat.img? I asked to avoid having to test Medicat.ing again because the file is too big.

Steve2926, have you tried booting successfully with Medicat.img? I asked to avoid having to test Medicat.ing again because the file is too big.

Read my previous posts in this thread!

After renaming Medicat.vhd to Medicat.img, ventoy boot to Medicat.img, the list comes up, choose to try an iso file from a directory, the pc reboots itself. So booting is not successful.My pc configuration ram 4g dd2, intel core2 1.8ghz

Also, if you rename Medicat.vhd to Medicat.vhd.vtoy, ventoy will still boot into Medicat.vhd.vtoy and get titles like Medicar.img, choose to boot from one, the pc won't reboot but pause at quotation marks "_"

Note : your vhd file must be of fixed size
See here https://www.ventoy.net/en/plugin_vtoyboot.html

I have found that you can Legacy boot to the Medicat VHD .img file using grub4dos

1. Download the grub4dos  grub.exe file and copy it to your Ventoy disk - root

2. Add the following lines to the \ventoy\ventoy_grub.cfg file (make one if it does not exist)

Code:

if [ "${grub_platform}_${grub_cpu}" = "pc_i386" ]; then

menuentry "Run Medicat using grub4dos (Legacy)" --class=custom {
set root=${vtoydev},1
set mycmd="map --heads=0 --sectors-per-track=0 (hd0,0)/Medicat.img (hd) ;; map --hook ;; rootnoverify (hd-1) ;; chainloader +1 ;; ls / ;; boot";
# line below must not exceed 255 chars when expanded
linux /grub.exe --config-file=${mycmd};
boot
}

fi

The Medicat.img file should also be contiguous - use Defraggler to defrag it.

Legacy boot to Ventoy and Press F6 for the extended menu.

The following Medicat payloads have problems:
RescueZilla - FAILS
BootIt Bare Metal - use F1  - end name with _VTMEMDISK.iso
Boot Repair Disk - FAILS
Rescatux - FAILS
Super Grub Disk - FAILS
Ultimate Boot CD - some linux ISOs fail
System Rescue -  use F1  - end name with _VTMEMDISK.iso
Parted Magic - FAILS

Extract and copy the ISO files to the Ventoy USB disk if you need them!

Thank you, but boot failed
