I should have timed the whole thing but the actual install from DVD took around 15 to 20 minutes max.
Printer install of HP Deskjet about 1 minute including a test print! It configures automatically as soon as it is turned on.
Download of 150 updates totalling 280 mb took 7 minutes.
The installation of the updates took 9 minutes with no request for a restart, although I did one.
This was on a low powered desktop with a Pentium dual core processor, 4 gigs of ram, and HD Graphics. Motherboard about 2 years old.
I guess it is similar in speed to a pretty cheap laptop. I mention all of this to encourage anyone who is less than thrilled with Windows to give it a go. If you use Ubuntu 16.04 or Mint 18 there is a good chance that the install will be totally drama free with the installer offering to install alongside Windows 7/10. (I'm sure all Geekzone members know all about the need to back up their data and have copies of Windows restore images before trying any of this.)
Provided your laptop can use DVDs I think this is the easiest option. Just download the Ubuntu or Mint iso directly, or by torrent & burn the DVD iso image.
