[Robin Laing]

I need to do the windows 10 upgrade on a dual boot laptop.  Any serious 
worries I need to watch out for?

Thank you in advance.

I did this twice. In both cases I had a dual-boot Windows plus Linux / 
and /home and swap. In one case it worked perfectly. In the other case,
it turned the two Linux partitions (but not swap) into one big 
"unallocated" partition. I never knew why. I did not try to rescue the
"unallocated" partition--it might have had the files and data buried in 
it, but I don't know. So my best advice to you is to backup anything
you want to keep onto a USB drive or something before you do it. And of 
course, Windows will almost certainly wipe out your
dual-boot, so you will have to set that back up. (Windows can't seem to 
install anything big without rebooting a time or two, so it sets
up its own boot manager.) Oh, I tried to do it one other time, with some 
poorly documented program that was supposed to let
Windows operate the dual-boot function. This time I wound up losing 
Windows 7, so I had nothing to upgrade from. Altho I really
hardly ever use Windows, there are one or two things that I need it for, 
and I usually need it on _that_ machine, so I bought a new
Win 10-Pro disk and installed it, and then reinstalled Linux. Phooey!

Hello Doug,

Thank you.

I guess I will get prepared to do an install if needed.  You confirmed 
my thoughts.

I need to upgrade the machine to Fedora 24 so I thought I would kill two 
birds with one stone and as I am prepared for Windows to screw things 
up, I will let it go first.

I tried to get windows boot manager to work as well with no success.  It 
happened when I needed the computer for work.  It was a failure.  At 
least the Linux boot was good.  That machine now has no windows.

Just do the upgrade to Windows 10 and reinstall new Fedora 24 : When  
upgrading to Windows 10 Fedora keeps in the bootloader the name of the  
former version of Windows , then reinstall new Fdora 24 and in the  
bootloader appears Windows 10.

My experience is that when you upgrade or do a new install of Windows dual  
boot does not functionate anymore.

I haven't played around with this functionality for quite some time 
since moving from a Linux distro that allowed the linux boot blocks (and 
hence dual boot functionality) to be installed to a partition.
As I understand it a Windows install will install its boot blocks to the 
mbr of the disk it is installed on. Grub via grub2-install will let you 
install the grub boot blocks to the mbr on any physical disk that is 
available, so if you multiple disks you can install the grub dual-boot 
boot blocks to hard disk that Windows is not installed on, and then 
configure your bios (assuming your bios has this capability) to boot 
from the disk that has the linux boot blocks instead of the disk that 
has the windows boot blocks.
Failing that there is an application that you can install on to a dvd 
that will search your system for grub config files and let you boot from 
any entry in the configs it can find, so you could use it to boot back 
into linux and then use grub to put the dual-boot boot blocks back into 
the mbr.

regards,
Steve

I thought I would post my experience.

I started with the fear that it was going to create many headaches.  I 
was wrong.

I found the link to upgrade to Windows 10 off the Microsoft site and 
started the process.  Fingers crossed.

Various files were downloaded and then it was time to reboot so I did. 
I was expecting some strange issue on the boot but when the machine 
asked me to select Windows from grub, I was a bit surprised.  Of course 
this was the first boot.

Windows 10 installation started and the reboot process started.  I was 
not paying attention so when I looked again, I was being prompted for 
the Linux password.  CTRL+ALT+DEL and found that grub was still coming 
up.  Booted into windows.  All windows reboots were going to grub.

At the end, I had Windows 10 installed and tested and it was still being 
booted through grub.  I was very surprised and happy.

Booted into Fedora 23 and did the dnf upgrade with only one issue. 
Using KDE and sddm was not installed.  Booted into a terminal. 
Installed sddm and target graphical.default and all was well.

Full upgrade of both systems were done in less than 6 hours without rushing.

I guess Microsoft isn't so bad now.

Note, this machine is using GPT partitions and has secure boot enabled 
(other issues in the future).

Thanks to all that gave comments.
