Cannot open DOS in VHD

[BridgeHeadland]

Describe the bug

With main-osfree , we have to run DOS (preferably MS-DOS 8.0) in an image file, and then I prefer VHD, since it can be up to 32 GB. I am not able to install MS-DOS while the VHD is mounted as C, so I have to use 2 (a number between 0-5) instead. Booting MS-DOS while the VHD is mounted as 2 makes DOSBox do an infinite restart loop, same with C if it is mounted with "-t hdd", but if I boot with C, without "-t hdd", I get this message: "Mounting FAT filesystem not supported", and with "-fs none" the VHD has to be mounted with a number between 0-5. :)

Steps to reproduce the behaviour

Install MS-DOS in a VHD in a possible way, then run it in a possible way.

Expected behavior

I expect it will be possible to run any version of DOS in a VHD file of up to 32 GB in DOSBox-X, without any problems.

Is this true of both main (master) branches and OSFREE, or only OSFREE?

[joncampbell123]

I made a VHD image of Windows 95 that OSFREE was able to IMGMOUNT and BOOT just fine.

[joncampbell123]

OSFREE builds are not supposed to support mounting the FAT filesystem or ISO 9660 filesystem to a drive letter, because MS-DOS is not supposed to be there.
