 Dear Maintainer, 
  
 Situation: performing a fresh install using 13.1 netinst on amd64. 
  
 I want to keep the existing partition table and one partition 
 containing data, but reformat the root and EFI partitions. 
  
 Problem: When manual partitioning during install, the installer always 
 marks an EFI partition as "K" meaning keep exsisting data, even if 
 there is no filesystem in the partition.  This means it cannot mount 
 the partition and installation cannot proceed.  The system is left 
 unbootable. 
  
 There is no menu option to format the partition presented, as there 
 would be for any other type of partition. 
  
 There is an "erase data on this partition" option.  If this is selected 
 and confirmed then it is obviously essential to format the partition, 
 but it is not possible to do so. 
  
 Expected behaviour: 
  
 Once "Erase data on this partition" has been selected and confirmed, the 
 partition must always be formatted (FAT32) if "use as" is set to "EFI 
 partition". 
  
 Even if "Erase data on this partition" has not been selected there 
 should still be the option to (re-)format an EFI partition. 
  
 I understand that some buggy BIOSes don't like you to reformat the EFI 
 partition, but if I have chosen the adavanced installer and after that 
 chosen manual partitioning so you must allow me to make my own choices. 
 Put a warning on the confirmation dialog by all means, but put it on 
 the erase dialog too! 
  
 As it is this allows a user to erase the EFI partition and then refuses 
 to format it. 
  
 Many thanks, 
 Tom
