Not all CPUs entered broadcast exception handler Kernel Error

I've been dual booting Ubuntu on my laptop and for a few months its been perfect. Today however when booting up this error has appeared, and despite numerous restarts nothing has resolved it: Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler Kernel Offset: disabled Rebooting in 30 seconds. When booting into Windows 10 I have no problems or issues, so I dont think its a hardware issue, maybe an update that has prevented an Ubuntu boot. I've looked around for solutions but most say it's a hardware issue (which I doubt) or I need to update the Intel Microcode, however if I can't load into Ubuntu and install it how can I possibly update the microcode?
