I have an HP 2000z-2d00 with Windows 8 here. It has the FBI ransomware on it. With Windows 7 and previous, I simply boot into HitmanPro's Kickstarter on a USB stick. This system won't let me boot from the USB stick OR the DVD drive. This is my first malware removal attempt on a Windows8 system, and I am at a complete loss. Can anyone help?
