After having some bad experiences with Windows 10 network (as in even with updated drivers, connections are half speed what a Linux live boot can achieve) I decided to dual boot my laptop to test Ubuntu from the SSD.

Lucky I had created a Windows 10 image and a repair boot USB key before that. Installed Linux but unless I press the ESC key and go into the BIOS config to select which partition to boot from, it goes into a boot loop - and even so it only boots from Ubuntu, Windows will just restart the laptop.

I was expecting grub to show up and give me the option of loading either Windows or Ubuntu.

At the end I just used the recover USB key to boot and reload the Windows image backup, blowing all the boot and partition information created by the Ubuntu install.

Perhaps something else should be changed if using UEFI?

I had to disable Secure Boot in UEFI on my HP laptop to boot Ubuntu. It prevents executing non-trusted system loaders, like grub.

Thanks. Will this affect Windows 10 boot?

Shouldn't affect. Though I did not test, I dumped Windows 10 as soon as unboxed the laptop :)

I have found NeoSmart's EasyBCD convenient for several years, tri-booting Windows 10 RTM, Mint and Windows 10 Fast Ring. Using legacy boot but I see NeoSmart say EasyBCD is UEFI ready.

I have found that getting Windows 10 to do updates properly requires that you use its bootloader. Some updates work, but others just give you an error code if it was booted via Grub. So what I do now is to switch the Windows bootloader back to the "legacy" text mode (so it runs much faster), then install Ubuntu on its own partition, but telling it to install grub on that partition, rather than on the first track of the drive. Then I boot Windows and use EasyBCD to manually create a boot entry that boots Grub by chainloading it. Chainloading is unreliable - if you install another partition or another hard drive, it can stop working, but usually all you need to do to fix it again is to run EasyBCD and delete the current boot entry and create it again.

Switching to legacy mode:

One more thought. "Fast startup" enabled in Windows 10 power options which prevents Windows from fully shutting down and allowing other OSes to use the disk.

I don't know if this suggestion is useful but Ubuntu or Mint run very acceptably when installed onto a Seagate 1tb portable HD. There is the hassle of having to enter the bios each time to select the Seagate, but otherwise it works very well if using a USB 3 port.

Yes, it is annoying that Windows 10 reverts the "Turn on fast start-up" to [enabled] each time after updating to a new "Version". But although I have had a fair share of random problems installing Windows 10 updates over the years, I have not had reason (as per fe31nz) to attribute those difficulties to EasyBCD (but I don't use UEFI).

In Win 7 days dual boot was a piece of cake and I did it all the time. Since Win 10 I have given up trying to dual boot, it is just too much grief. I now run dedicated Linux machines and dedicated Windows machines. One exception dual boot still works fine on my iMac with Win 10 and MacOS.

Here is a crazy notion, lets give peace a chance.

Yet another way of doing this on a desktop pc is having 2 hard drives, each with a sata cable. Then just remove the sata cable of the hard drive you are not going to use that day. This method assumes the side cover of your PC is easy to get at, easy to remove, or no side cover!

I actually would like to try Linux but looking at some of the Exchange client options, it seems to still be... lacking. Even Android GMail app (or Android Outlook app) on a Chromebook give better results than a couple I tried on Linux.

Have you tried Mailspring?

Yeah, that's true. My work email is on Exchange and I use evolution + evolution-ews plugin. It does the job actually.

Slightly off-topic but related, I discovered recently that the "fast startup" option also prevents Wake-on-lan from working.

If you have a modern PC with SSD you shouldn't even bother with fast startup.
