So I have 2 USB sticks, and i'm ready to install Tails. I'm able to press enter at the screen where it says setup then troubleshoot, and then once I get to the first installation page, I can't move my mouse, use my arrowkeys or anything. Does anything know any fixes for this? I also turned on IOMMU in the BIOS. That didn't do anything..

Loads of things to verify, since you did not provide any backgrounds --

1. Make and model of your computer. Search the web with the model number and linux version (distro used) to see if there is any known problem (and if you are lucky, a workaround) is documented.

2. Verify if the "Tails" iso version is valid. Check if the website lists any sha256sum (or other) hashes, and find out if it matches with your downloaded version. If they don't, download the ISO from the official page and reverify.

3. If your KB/M is PS/2, try with USB.

4. Make sure you are using the correct ISO for your CPU architecture type. (i.e. attempting to install a 64 bit OS on a 32 bit CPU, this is typically very rare, unless you have a very old machine.)

5. Check with a different, mainstream ISO to check if the KB&M problem exists. (Mint/Manjaro/OpenSUSE are yet to fail on any computer I have come across)
