thinking about buying some low-capacity usb pendrives to do some experiments in my very old pc upstairs because using a 32Gb one just to put on it an ISO image of less than 1Gb seems like a waste (and I've tried a lot of multiboot usb creating tools without success in that machine so the ones that write only one ISO in the usb thing is the only option in that hardware)
@ordenauta maybe an sad card with an older reader?
