I tried it, and I first I was getting the same result as you... Choosing to boot the USB key, result in message to insert a valid disk...
Until I realized that I had written a .iso file on the USB key rather than the freshly dowloaded .img file. (More precisely was wrongly writing FD13LIVE.iso file). What works for me is: https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.3/official/FD13-LiteUSB.zip more precisely the FD13LITE.img file. Then the boot order is important... Might consider to try to boot a Linux ISO in Legacy mode to be sure you get the boot order right. _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
