I have a macbook air dual booting macOS Catalina and Debian10 buster. I hold the option key at startup to choose the system I want. In the boot manager there's this efi partition (https://imgur.com/xKoQiEK) that I would like to delete, because it starts nothing but grub bash minimal (https://imgur.com/a/T5bpHAp), but I have not been able to identify this partition neither from macOS 'diskutils' nor from Debian 'fdisk'.
How could I delete this partition?
EDIT:
Command diskutil list disk0
output:
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *512.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 305.9 GB disk0s2
3: Microsoft Basic Data 205.5 GB disk0s3
4: EFI NO NAME 536.9 MB disk0s4
lsblk
,mount | grep sda
and/usr/sbin/gdisk -l /dev/sda
? You may have to be the root user to enter the command/usr/sbin/gdisk -l /dev/sda
. Or, post the output from the macOS commanddiskutil list
