Many people use a dual boot setup on their PCs depending on their requirements and need. Some use both Ubuntu and Windows 10 because both have their pros and cons.

Ubuntu, like many other non-Windows operating systems, does support dual booting. Windows 10, on the other hand, usually ships with settings that are not optimal for dual boot setups.

GRUB (the acronym for GRand Unified Bootloader) is the bootloader which is used by Ubuntu to manage the operating systems installed on your computer.

Basically, it is the software that looks at the operating systems installed on your PC and allows you to choose which one to start after switching on the machine.

Most of the problems are related to GRUB, so if you are unable to boot into Grub and the system boots directly to Windows repeatedly, you are going to find below some solutions to this problem.

Solution 4: Windows and Ubuntu are installed in different modes

It is not possible to dual boot two operating systems if they are installed in different modes – one in UEFI mode and the other one in BIOS Legacy mode.

Therefore, to solve the problem and restore the dual boot you have to convert the installation of Ubuntu to the same mode in which Windows is installed.

In order to solve this, you can use the Boot Repair Utility and you will need a live bootable DVD of your installed operating system. Afterwards, you can follow one of the steps below, depending on your situation.

Afterwards, enter into the UEFI firmware configuration panel and choose whether to start the computer in UEFI or Legacy mode.
