I have a PC that's so old that it cannot boot a USB disk. It can only boot a PATA IDE disk. Using a USB-to-IDE cable, I installed Ventoy on the PATA drive. Installation worked fine. Then I removed the USB-to-IDE cable and installed the drive directly on the IDE bus of the old PC. Ventoy refused to boot, giving a message stating that the disk is not supported.

If the disk is not supported, then Ventoy should have refused to install immediately so users don't spend time building a disk that will fail. But in any case, this should be made to work so that a drive holding ventoy can be attached by either USB cable or IDE cable. GRUB has no problem booting this drive if I configure it manually, so it's unclear why Ventoy has this limitation.

Note that the workaround is to manually configure GRUB, but doing so is difficult without knowing the ISO-specific parameters. This requested feature will make that convenient:
