Might be a bug with the installer possibly? You should be able to achieve this using the manual partitioning method. ---

First: @steeepaaaan Welcome to the forum! đź’ś > [@steeepaaaan](#): > > I want to install endeavouros, but when its time to choose the bootloader i choose grub but i can not choose Btrfs as the File system, it still says ext4. How can i fix this issue? If I read your screenshot correct you would like to install EOS as dualboot to a Windows installation, right? I remember that I had the same problem the last time I wanted to install EOS as dualboot to windows. To fix this you have to change a file before running the calamares installer. Start your live system and open the terminal. Use the editor of your choice like `nano /etc/calamares/modules/partition.conf` to open this file. Look for the line `defaultFileSystemType` and change `ext4` to `btrfs`. Then save the file and run the installer as you tried. `btrfs` will be used to format the partition. ---

> [@darkelenia](#): > > Might be a bug with the installer possibly? You should be able to achieve this using the manual partitioning method. It looks like a bug of the installer. But only e.g. @dalto or @joekamprad may answer this. See my workaround above. ---

If you have a MSI Mobo you need to look for an option called BBS priority, or if you have another Mobo you might have to add a administrator password to reveal extra options. ---

When you were installing, did the installer give you a choice between grub and no bootloader or was it choice between systemd-boot, grub and no bootloader? ---

replacing empty space again? and using “replace Partition” @dalto i see the same here was installing aside Windows 11 on the Framework 16 to test EndevourOS running on it.. similar setup created free space from win 11 boot booted in the installer and try the option to replace partition. Same thing happen, you can select btrfs but it stays on ext in the view and installes ext4 instead the same. .. same also in case you use any setup its related to “replace partition” and slecting empty space.
