Yesterday I installed Ubuntu 16.04.3 on my hard drive, which already had Windos XP and Windows 10. (I made a backup before I stated.)
Ubuntu did install
grub, the linux boot manager wiht no problems, But I wanted the default to be Windows, not Ubuntu. This was a custom install.
So I also found a neat little thing for
grub to be a visual thing.
The nmount points in Linux confuse me, so I kput the script I found on a USB stick. Here is the script I sed to make the boot manager eay to modify.
$ sudo add-apt-repository ppa:danielrichter2007/grub-customizer
$ sudo apt-get update
$ sudo apt-get install grub-customizer
The $ represents the prompt you get from the shell in a terminal mode thing. You type in the stuff after the $.
Tokk me a bit to remember that. I am getting older.After doing that, there is a new thing for grub that lets you see what the boot list is. Yu can move an entry up or down. The top item is the default.
So I put Windows 10 on the top. It works, nd up comes the windows 10 boot manager that lets me pick either Windows 10 or the eralier verson of Windows. Which happens to be Windows XP.
So now I can have Ubuntu anytime I want without waiting for the live demo DVD to load.
Ubuntu takes very little disk space. It takes only about 5 GB for Ubuntu 16.04 and a little pbit of swap space. But I put it on a much larger partition so it has room to grow. Even so, I still have spare room on my 250 Gb hard drive on this old Dell 755 ATX size desktop. BTW, I have my HDD in the old MBR style, not the new thing. The new thing for HDD is not needed if yu do not have a monster drive. So I made no effort to go with the new standard for HDD. Cn't even remember what it is called.
I recomend yu try Ununtu 16.04.3 Lts for yhourself. It is very nice and ease to use. On the internet, it performs as well or even better taht a Windows based system. You have a choice of Firefox and other popular web browsers.It has not problem reading test and image files creadted by Windows. Libre Office is included, as well as the usual Linux things.
Hope you enjoy Linux. If something bad happens to your Windows install, you can boot up Umbutu and get on the Internet. Nice to have it ahndy.
