Edit the value of the "Bootmulti=" option and check and correct the "boot path" in your msdos.sys file.
Look on the Root of C drive for the MSDOS.SYS file. (MAKE A BACKUP COPY IN ANOTHER FOLDER BEFORE CHANGING THE ORIGINAL)It is hidden system fileso you will have to have the "show all files" option selected in your "folder option / view tab". Open the MSDOS.SYS file in notepad or any text editor. After opening MSDOS.SYS in the text editor, look for the section labeled "Options". Under options find the line that Says "Bootmulti=1" Change the 1 to 0 (zero). Next look at the "Path" section and make sure the "WinDir=" and the "WinBootDir=" and the "HostWinBootDrv=" all point to the correct drive and directory for your Win ME. Then save the changes and restart. The dual boot option will be gone and you should boot directly to ME.
