I've made a mistake on a cpu that has both windows 10 and 7 in different partitions.

I was moving files between partitions and ended up moving windows operation system's files. Now I can't startup neither with windows 10 or 7

Is there a way to chose with windows to startup by using the dos system?

If you messed up the system files you will need to do a Windows reset from a Windows install media.

Try pc reset or system restore...if you don't want to do both.. changing the os is the only option out there... Is the boot meni still accessible?
