I reinstalled Ubuntu 17.04 Desktop 64-bit UEFI on my Laptop on a harddisk.
Laptop: Intel Core i5-5200U, Intel HD Graphics 5500, 16 GB Ram.
Booting takes ~120 seconds (from pressing the powerswitch to loginscreen, with Ubuntu 16.04.2 on a ssd it takes less than 20 seconds).

partition and why is it so big? This questions are more rhetorical than anything else and have the sole purpose of alerting you that you're doing the opposite of the recommended practices therefore problems are to be expected (as shown in the systemd log). – Apr 15 '17 at 09:04/boot
partition is only required for LVM. Otherwise is not even recommended. 2. Legacy boot can only be as good as the native (and always recommended) UEFI mode, never better and often worse for hardware support. 3. Not mentioned in your specs but if you have an addon graphics cards you may need to install proprietary drivers.
