This question already has an answer here:
After running linux in a virtual machine for a while, i decided to try to dual boot it on my 2014 i5 linux desktop (not sure exact model). After following many guides and about 5 hours of installations, updates, changing settings etc, my computer gave up. It stopped working, and would not even load the bios. It black screened and would do nothing at all when turned on. after trying for days to fix it i gave up andf bought a new pc.
I now have a HP Pavilion 550-153na but i am very weary of dual booting it with ubuntu after what happened last time. Could someone please help me with an in depth explanation of how to to this process? If there is already a guide that will definitley will work with my PC please do link me to it, if not hopefully someone could advise me what to do.
