无法正确启动 FreeDOS 1.3 镜像文件

[DOSforever]

试过 FD13FULL.img 和 FD13LGCY.iso 两种镜像文件都不行。
使用的是目前最新的 ventoy 1.0.97 版，格式化闪存盘时勾选了 Security Boot Support ，当然启动是在 Legacy BIOS 下启动的机器。文件系统试过 NTFS 和 FAT32 都不行。
启动倒是可以启动，但启动 FD13FULL.img 后最后提示找不到 COMMAND.COM 文件。但如果单独把该 .img 文件写到闪存盘中是可以正常启动并安装 DOS 的，镜像文件没有问题。
如果选择 FD13LGCY.iso 文件，则可以出现让你选择正常启动，还是模拟 GRUB2 启动、内存盘启动等几种启动模式菜单，但选择任何一种都无法启动，死机无反应。

Please take a photo or record a clip and send it to the loading process of FD13FULL.img or FD13LGCY.iso (when pressing the d key), my computer is ancient (HP compad core 2; 4g ram) but using Ventoy still loads and boots 2 the above file is normal, there are no errors like yours.
What brand is your usb drive? How much storage memory is there? I suspect the error is from your usb drive.
Try recreating the Ventoy boot, with the partition type MBR
