Windows 10: Issues dual booting Ubuntu 15.10 and Windows 10
Issues dual booting Ubuntu 15.10 and Windows 10
I'm having some troubles trying to get Ubuntu 15.10 64 bit dual-booted with Windows 10 64 bit.
Firstly, I burned the latest ISO from the official Ubuntu website to an 8GB USB formatted to FAT-32 using Universal-USB-Installer.
I then restarted my computer and changed the USB boot order to position 1, proceeding to boot through the USB and then selected the 'Try ubuntu' option. The computer successfully launched into the Ubuntu operating system, however when I selected the install desktop icon and have confirmed setup installation, I am greeted with the following error:
Force UEFI Installation? This machines's firmware has started this installer in UEFI mode but it looks like there maybe existing operating systems already installed using BIOS compatibility mode, If you continue to install Debian in UEFI mode, it might be difficult to reboot into any BIOS-mode operating system.
I looked around to find the cause, I've tried disabling Fast Boot in the BIOS and Windows 10 operating system as well as looking for alternative installation approaches using Legacy (non UEFI) BIOS, however the issue still seems to be occurring.
Could anyone help me with this please, can provide more information on request.
This tutorial worked for me:
Installing Ubuntu/Linux Mint on UEFI System with Windows 8 / 8.1 / 10
Hello Infinite Welcome to the Ten Forums!
The first problem you will run into immediately by your description is trying to replace 10 with Ubuntu which is why you are having difficulties to start with. Did you split the drive up first or are you simply trying to install Ubuntu along side 10 on the exact same primary partition? That would be an automatic fail.
The best options for setting up any dual boot between any Linux distro along side any Windows install in addition to seeing a drive split into at least two OS partitions is to install each OS on totally separate drives and then install Grub2 in order to see the two OSs work friendly with each other. The fast and easy solution to simply look at the latest release however won't even requite any of that. You simply run a Linux VM on Virtual Box, one of the VM ware programs. or with 10 even with a Hyper-V type VM. where you run the distro live on VM rather then booting separately to it.
Some time back before 10 came along and not seeing 8 or 8.1 on the second OS then split to see a second partition used for backup purposes the front end saw a 100gb partition for Linux Mint Debian there. The Linux install was seen while the 7 drive was unplugged in order to avoid trashing the Windows boot sector and mbr information with the F12 boot menu brought up. Later VM Player was to eventually replace the need to tie up the second OS drive that now sees 10 dual booted with 7. Both versions still see Linux Mint and a Ubuntu 15:10 VM however whiile 10 has the Hyper-V feature in use there.
Now for reference you may also want to look over a thread not quite yet marked solved at this time where someone had been trying to get information on seeing a 15:04 dual boot set up with 10. The EasyBCD program and other tools are referred to in the thread seen at Dual Booting Windows 10 and Ubuntu 15.04 - Windows 10 Forums
With the main system here I run multiple OSs having two OS drives for the Windows 10/7 dual boot along with several VMs for both Windows and Linux distros that can dumped at any time when a new release comes out for the Linux equation that is. It saves the need to wipe and install each "Flavor of the Month" for any particular distro and won't involve the need to change any bios settings. Just a suggestion to add here.
I have a dual boot system that had been working fine until yesterday.
Now when I go to boot Windows the grub menu shows
"Windows Recovery Environment (loader) (on /dev/sda3)"
This leads to a window splash screen that last for about 10...
I've just built my desktop and I'm trying to dual boot Windows 10 and Ubuntu 15.04.
I've already partitioned my hard drive, and installed Windows 10 and Ubuntu 15.04, but I'm trying to get to a place where I can choose what OS to start...
I set up Ubuntu in dual boot with Win 10 and tried to replace it with Mint, which failed at installation.
I then had a "grub rescue" prompt regardless of what I tried.
I fixed the mbr by booting from Win 7 .iso and running Bootrec /fixmbr.
I have both windows 7 and 8 installed and reboot to switch from one to the other. If I upgraded one of the windows installations to windows 10; will it affect the installation of the other? In other words, will I still be able to dual boot?
I have just upgraded windows 7 to windows 10...
I've bought a new ssd to install windows 10, but it was installed over my windows 7(in the old ssd) in the process....
Articles in this forum say that you cannot dual boot windows 7 and windows 10,...
