Configuring Multi-boot Filesystems
When installing a fresh Linux Distribution, you might want to dual-boot, or even multi-boot, into different desktop environments. There are some pretty specific requirements we'll need to setup manually for our new partitions though, see below for details on the different partitions we'll need to setup an open ended dual-boot system alongside windows. This configuration will prompt for selection of OS on boot, and will allow for nearly any number of distributions to be tested alongside each other. These instructions vary slightly based on your specific scenario, so be sure to read and understand the need for each setting below.
Choosing a Distribution
The steps below will help you select a distribution, and prepare your installation media.
Distrowatch
Not sure what distribution to use, or searching for a legit ISO?
Distrowatch is your friend. They provide rankings, comment boards, forums, and (usually) working links to ISO downloads.
ISO Image Writer
No bullshit, quick and easy. Don't mind the http, we won't be posting any information on their site, and this tool has been trusted by the Linux community for some time now. Simply browse and select your ISO, choose the USB device from the dropdown, click write.
Want to use the same USB for a different distro? Open ROSA, Select your USB, click clear. Navigate to the device within the explorer or disk management utility for your system, format it (NTFS). Select your ISO, USB device within ROSA and write to it. Repeat as many times as you see fit.
Configuring the Bootloader
If you are installing alongside windows, you can skip this step and simply select the already existing device that contains your Windows bootloader / EFI filesystem.
EFI Partition
Size:
Type:
Location:
Mount:
You should always choose to install the bootloader on the same disk the EFI filesystem exists, whether your case required the creation of a new EFI volume or if you are installing alongside a previous one. Failing to do so can could cause issues during installation.
