I purchased a m7-n109dx HP Envy laptop that came with Windows 10, so I decided to install Win 7. I wiped out the hard drive, during which the computer gave me weird errors upon deleting the partitions but It went away when I tried again.

After installing the windows It wouldn't recognize the USB controller, Network controller, PCI Data acquisition and Signal Processing controller, PCI device, PCI simple communications controller and a whole bunch of "Unknown devices" in the Device manager.

Plus, when trying to install a program, It would give me weird errors randomly, not installing the programs once and installing it on the next try and after a restart.

Why all these weird bugs? Please help
