Good to know, Ragnar! This is very good information. I've been fooling around with Ubuntu, as well as other versions of dual-boot Linux/Windows systems (mostly Linux-W10), and I've gotten a Ubuntu v16.0.4LTS & W10 dual-boot to work well on multiple test machines here.
I haven't yet tried v17.04 as I didn't know it was available yet. I haven't had too many problems installing it over the years; but what I have noticed is quirky things like the drives with dual-boot Linux & W10 after leaving them shut off for several days on my test machine, when I come back the multiboot doesn't work right and either the Ubuntu is scrambled or the W10 is scrambled and I have to restore my disk image from my Macrium backup or completely rebuild it. I'm still doing that from a trip I made back in June. I had to rebuilt both my Mint-W10 dual-boot drive and my Ubuntu-W10 dual-boot drive. My test PC is quite old; 10 years old last month; a Dell Dimension E520. I have 5 drives in this machine including the Ubuntu & Linux dual-boot drives. Only 3 can be physically hooked up to the SATA Motherboard connection simultaneously. I'm really not sure why this happens on this particular PC; it's the most stable test box I have and I do most of my W10 testing on it.
A couple of things I discovered along the way of building this setup include the big one.
You never want to install your Ubuntu (or any Linux) on a bare drive first, and then add in W10! That hasn't worked well for me on a variety of machines, not just the Dell PC. So, for other folks running into problems with Ubuntu installs, especially in dual-boot mode is that you should always do the install from the LiveCD to a working W10 machine (or other older windows version) in that fashion. This works best. It also applies to laptops and netbooks (Sony & Acer Aspire) which I've also installed Ubuntu on over the years. We've had several questions the last couple of years on this process, and I had asked our Admins to make a special sub-forum for people attempting this dual-boot Linux-Windows configuration. To date, it hasn't happened. Probably because they are so busy, and we only get a handful of these questions each year.
Another thing that's worth mentioning, is that once you have your dual-boot setup running on a machine, make sure that you run
SPEEDTEST.NET and check your Internet speed. When I installed Ubuntu on the Acer netbook with W10, I discovered quite by accident that I was only getting 14-18Mbps download speed on the unit. Being that my ISP, Spectrum is giving me 65Mpbs everywhere else on my network, I thought that was odd, and attributed it to the underpowered processor on the netbook. After fooling around with it for a few months, I decided to wipe the drive and just reinstall with a W10 stand-alone image I had for the netbook. And voila: the speed jumped back up to 22-23Mbps! Still not 65, but much better. That gave me pause for thought. The Ubuntu had severely throttled down my Internet speed for some reason. Wiped the drive again, and this time did a scratch Ubuntu install from LiveCD, and had the same 14-18Mbps slower speed. This netbook couldn't achieve a decent speed with Ubuntu loaded in either dual-boot mode or even by itself. W10 however, had no such problem.
This could be an isolated instance, but some of the other guys here have seen similar results on their machines. It seems to be limited to netbooks, tablets, and laptops with Celeron CPUs or Mobile Celerons however. No such speed throttling seems to exist on any of the several desktop PCs I've tested (Dell, HP, Acer/Gateway).
This isn't directly related to your Ubuntu install settings advice, but it might be if someone has never installed Ubuntu before or attempting to do a dual-boot setup. For anyone reading this, it might prove helpful. Also, the Ubuntu I used on the Acer netbook was v14.04.4, as the v16.0.4 version wouldn't work. I suspect neither will this newest v17.04 version.
Good post.
