You can have a look at your boot the boot screen, is entering the deepin boot screen selection system, or into win10 boot screen selection system, if it is win10 guided into, then you must be off the machine,If is deepin guide into, as long as the original didn't put the/boot boot in win10 disk interval, would not be a problem, so deepin can go in,
If really machines may not be able to open, you can only use U disk starts, to set the boot, boot
