Since getting a new keyboard I haven't been able to do anything in the grub menu. That hasn't been a problem for the last few months because Linux is my default but today I wanted to boot into windows and I can't.

I thought it was because I had plugged the keyboard into a USB3 port but swapping to a USB2 port made no difference. I tried with the BIOS USB legacy options on and off. I added the lines

to /etc/default/grub and ran grub-mkconfig but that doesn't make a difference either. I plugged in another USB keyboard and that doesn't work in grub either. The USB keyboards work fine in the BIOS and in Linux, just not grub.

I could have just plugged in a ps2 keyboard again (about 2000 times) in the time I have been playing around with this, but I would like to have my USB keyboard working. Any ideas?

So I plugged in a PS2 keyboard in the end, and that worked. But when I choose to boot Windows from the grub menu it tells me it can't find the partition that windows is installed on and goes back to the grub menu. I downloaded grub2-2.00 from 14.2 and reinstalled that and at least that can find my windows partition. Still no keyboard though. But grub 2.02 is broken.

Some tips here:
