I completely reformatted a drive and set up the partitions as I wanted them.
First I installed Windows 7 and things were smooth (keyboard mouse worked)
Then I installed Ubuntu 14.04 and Grub and things were smooth in ubuntu.
But then, when I chose Windows 7 from GRUB, my mouse and keyboard would both go dark (all the lights on them turn off) and no longer work which leaves me staring at the Windows login unable to interact with everything.
I have poured through my bios and all of my settings there were correct (especially enabling legacy usb and disabling fast boot options). I have tried all of the different usb ports and combos of plugging them in and unplugging them I can think of. My mouse and keyboard both still work in Ubuntu.
Does anyone have an idea why this might happy or how I can resolve it?
(I do not have a ps2 mouse/keyboard on hand but will try to pick one up tomorrow)
