Well the performance impact of virtualization is nowadays, what - 3-4% maximum compared to running direct on the hardware? So negligible.
I don't know. The vast majority of games are 32 bit, so there will be ongoing issues for a number of years, I would think, as people will still want to play those games. As to VM, I haven't successfully been able to run games in one yet, at least not up to par, but I guess a lot can happen in a few years. While 18.04 will continue to be supported, they have made some pretty major upgrades to Ubuntu since that release, which I found to be a bit buggy, at least on Ubuntu proper, much less so on some of its derivatives.
Agree, though there are a few that aim to make it as easy as possible. I wonder: if Valve actually does drop support for Ubuntu, if they would also slow down on their proton development which has been moving along at leaps and bounds. If they do that, it would affect all of linux, not just Ubuntu and its derivatives. I certainly hope they do not make that decision.
Canonical is going to reverse their decision. They have to. There's going to be massive breakage in the distro's support for common applications, and Canonical will be seriously shooting themselves in the foot if they don't. Yes, developers need to have been switching to the 64-bit architecture by now, but there are a lot of applications out there that still use 32-bit libraries.
Yes, I didn't even touch on all the other sorts of software that are still very much 32 bit. I have a hard time even thinking of those that run exclusively 64 bit except browsers. I'm sure there are plenty but I think 32 bit programs have to far outnumber them.
That's true for Windows. However, on the Linux side of things, most applications that are in active development have been recompiled for 64-bit environments, though there are still 32-bit variants out there. It's the applications that are no longer being actively developed is where all the breakage is going to happen.
Did you install Ubuntu second (after Windows) or first? If you installed Ubuntu first and Windows second, Grub doesn't show.
If you installed Windows after installing Ubuntu, you'll have to repair the GRUB installation. This link should help you with that. If you installed Ubuntu after Windows and GRUB still doesn't launch, that link might help you as well.
I did that once, either with Windows 8 or Windows 10 and had the same thing happen. Katheryne's link should get you through. There was also a time when Windows 10 updates were killing grub as well, but I believe that has been completely fixed.
