Windows 10 has already being installed before doing the following:

If it possible to install Ubuntu 16.04 LTS "Xenial Xerus" from Installation/MinimalCD on HDD as minimal as possible LowMemorySystems like in here: Windows Dual Boot together with Ubuntu 16.04 “Xenial Xerus” - minimal - command line installation

I would like only the kernel, and to boot in tty, and only use fvwm, no login manager, no other environment at all, if it is possible to work like this in Dual boot with Windows.

First I couldn't boot the new USB Stick created the before mentioned Ubuntu 16.04 LTS "Xenial Xerus" in UEFI mode like I've done with a few minutes ago, just for test with the Windows 10 USB Stick.

I had to boot it in Legacy mode, in order for the USB Stick of Ubuntu 16.04 LTS "Xenial Xerus" to run.

I installed the before mentioned Ubuntu 16.04 LTS "Xenial Xerus" - command line installation.

GRUB has been installed on ext4, dev/sdb2, ehere the root / patition is situated.

sda was the USB Stick.

All done, now in UEFI starts only Windows 10 automatically, and in Legacy mode, no system to start at all.

I don't know if I will use only the Legacy mode, will find the HDD at all(from my trying until now in Legacy only the USB could start).

When I try to access from WIndows the partition where Ubuntu should, I can't access it, and it asks only for formatting it.

Do you consider that if I would do this with a full Lubuntu desktop + login manager (not Ubuntu) installation would work, even with the UEFI and Legacy issues?

Thank you.

As a general rule, with windows using UEFI, you need to install any other systems using UEFI. If not, you may still be able to boot either by making changes in the BIOS on each boot. Dual booting Ubuntu/windows with UEFI is explained at the Ubuntu documentation site below. Reading that might help you to understand. You may need to turn off fastboot, hibernation, etc. in windows to boot.

That won't work in either case, MBR or UEFI. If it was an MBR install you would need to install Grub code to the MBR. If as it seems, it is an EFI install, you would need to install Grub files to the EFI partition on which the windows EFI files currently reside. The installer will create a separate folder to house these files alongside the windows files.

That is expected behavior. A windows system is not capable of reading a Linux filesystem without some third party software being installed. That is by design by microsoft.

Thank you very much for your time and valuable info.

I really appreciate.

Just to be sure do I understand well that if again at the next installation the system will recognize sda the usb sdb as the internal HDD, sdb1 the partition where Windows has been already installed, and sda2 the partition which I have already allocated for Linux, the Dual Boot will not work?


The Linux USB is still not recognized in UEFI like the Windows USB, the only way to boot the Linux USB is in Legacy mode.

With gratitude.
