Like this and i use these settings in manual installation
30000 gib space
No flag
Ext4 i guess
Mount /

And i change things to default using installation tutorials on youtube and the only thing that is problem here is mount, i can’t set it anything else beside /
If i select something else i can’t even click next it’s turning off and if i choose / in mount the error come back and the installation would stuck
I assume you are doing manual partitioning. It is obvious you don’t understand what is required.
The requirements for modern EFI (UEFI) systems:
Partition Table must be GPT here.
ESP (Efi System Partition) :
If you take systemd-bootloader:
Fat32, flagged as boot, Mount Point: /efi, Minimum size: 1024MB (1GB)
If you choose Grub Bootloader:
Fat32, flagged as boot, Mount Point: /boot/efi, Minimum size 300MB.
System Partition
Possible format ext4 or BTRFS Mount Point /
Edit: I have provided a link to the wiki and if your system is legacy Bios then that section is at the bottom and is slightly different. I don’t know what your hardware is.
