When I'm on Linux and I reboot the machine and choose to boot on Windows 7, the keyboard and mouse are turned off, like they aren't receiving power. After another reboot they work fine (unplugging and plugging doesn't work, reboot is the only way), but it's pretty annoying and it's also not good for the machine.
The reboot can be done once Windows started, but I have to use the machine's reset button, ctrl alt delete obviously doesn't work. It can, however, be done with ctrl alt delete during the BIOS phase.
This doesn't happen when going from Windows to Windows, or Windows to Linux.
What can be causing this? What can I do to fix it?
