I installed Manjaro but it won't work

so I have seen many posts like this and j have read many of them but here are my issues. It has been repeated stated you need 512 mb in fat 32 for uefi. If you let the program erase the disk and do it its self in only gives a 300mb fat32 partition. Now when i choose manual partition i can create 2 partition in the correct size but the next button will not light up so I can continue. What am I missing

The boot partition might be flagged correctly. Something like that:

Nummer  Anfang  Ende   Größe   Dateisystem     Name  Flags
 1      2097kB  317MB  315MB   fat32           boot  boot, esp
 2      317MB   226GB  226GB   ext4            root
 3      226GB   239GB  12,6GB  linux-swap(v1)  swap  swap


  1. The size of efi partition doesn’t have to be 512mb, it work just fine with 300mb for a normal use.
  2. Did you flag the efi partition like @megavolt told you?
  3. Did you aply changes in the program?
  4. Did you choose uefi mode in bios?
  5. Did you choose the right boot order in bios?
