Aus der Mint-Seite ergibt sich unter Installationsanweisungen, dass Du eine "/"-Partition brauchst, es wird empfohlen, dieser 100 GB (!) zu geben, darüber hinaus eine Swap-Partition. Ext4 ist, habe ich gesehen, das Standard-Filesystem unter Mint.
If you want to manage the partitions or specify which partitions to use, select Something else.
Linux Mint requires one partition to be mounted on the root / directory.
The Linux Mint operating system (without additional software or personal data) takes roughly 15GB, so give this partition a decent size (100GB or more).
ext4 is recommended. It is the most popular Linux filesystem.

Also create a swap partition. This partition is used for hibernation and as a safety buffer in case your computer runs out of RAM. Give this partition a size equal to the amount of RAM in your computer.
