VER_PDM_MEDIA_LOCKED message when installing Guest Assistant

Post by BmB »

Hi, the thread title is the message I get when I try to install via Devices Menu and the bottom menu item. I have searched the web and none of the solutions there worked - they were all for other OS though.
I don't know what to do....I also tried manual install then I get the message "The VBOXWINDOWSADDITONS.EXE file is linked to missing export NTDLL.DLL:NtQueryObject."
Any help appreciated! The host is Windows 10, the Guest is Windows 98SE

Web-search CAPITALIZED_UNDERSCORE_SPACED error messages to get quick help:

VER_PDM_MEDIA_LOCKED site:forums.virtualbox.org

Searching this error message will point to the problem in your setup, for other guest OS's.

However, there are no Guest Additions for Windows 95, 98, or ME. So clearing up the 'Media Locked' problem will not help you this time.

See the Windows Guests Tutorials for setup help for 98 that can make the OS work better: viewforum.php?f=28
