On any machine that has a FDC floppy disk controller (all legacy motherboards, unless you convinced BIOS to disable the FDC), Windows will automatically display an A:\ drive, even if BIOS doesn't see one. So helpful, huh? LOL.
If you're in Windows 98, open a command prompt (command.com) and type SYS C: E: to copy the boot sector and boot files (io.sys, command.com, and a "blank" msdos.sys settings file) from C to E
Windows ME is programmed to not allow SYS to any drive other than A: or B: thanks Microsoft!
(it's one of the ways MS tried to pretend Windows ME wasn't running on top of DOS exactly like 9x, so they could advertise ME as a superior OS hahaha
)
