Here's what you need to do:
- Install Windows or if Windows is already installed make sure there's room on the hard drive for Linux, if not then shrink the windows partition
- install Ubuntu - choose to "Install Ubuntu alongside Windows Boot Manager."
Legacy BIOS Dual Boot
For computers with Standard BIOS.
Here's what you need to do:
- Install Windows or if Windows is already installed make sure there's room on the hard drive for Linux, if not then shrink the windows partition
- install Ubuntu - choose to "Install Ubuntu alongside Windows Boot Manager."
- Edit the boot order to make sure Ubuntu can boot
Turn off fast boot Turn off secure boot Install Ubuntu
Resize "shrink" the Windows Partition
This step is relative to both Standard and UEFI BIOS. If Windows is already installed and occupying all of the available hard drive space, then it needs to be reduced to free up space for the Linux partitions.
