[agusdepaso]

I'm tryng to install win 7 in a MSI B250M PRO-VH with a 500 GB HDD WD blue.
I install Windows, but when I get here

Mouse and keyboard just does not work. They are both USB and I dont have a keyboard PS2 right now.

Someone can help me?

Where exactly did you get your iso from again, also what brand and model number are you keyboards by chance.
When you started up the windows installation usb/dvd drive did the keyboard flash 3 times during preposting of your system ?
Your motherboard has usb 3.0, sadly windows 7 will not support it yet, try finding or borrowing a usb 2.0 keyboard and mouse.

Check the motherboard manual and look at the diagram closely for the mobo where it indicates usb 2.0 ports.
Pluck a regular usb 2.0 keyboard in it, if that works you can navigate the installation with a keyboard until its done.
Use the tab key to get around, you will a dotted box of what is selected or highlighted.
