erased EFI volume

[rafa226]

Hello

I work on a hackintosh on 10.13.2 with clover r4380 since months and i am very happy with it.

This afternoon, while struggling with a bad SD card, i mismatched an diskutil command in terminal, and i made :
diskutil eraseVolume FAT32 PI /dev/disk2s1
instead of
diskutil eraseVolume FAT32 PI /dev/disk7s1

disk2s1 was the EFI partition of the system disk !!!

before mistake, diskutil list returned :

/dev/disk2 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.1 GB disk2
1: EFI EFI 209.7 MB disk2s1
2: Apple_APFS Container disk4 499.9 GB disk2s2

and now it shows :

/dev/disk2 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.1 GB disk2
1: Microsoft Basic Data 209.7 MB disk2s1
2: Apple_APFS Container disk4 499.9 GB disk2s2

I fear next reboot won't be easy ...
I made a backup of the EFI partition content on a USB dongle.

What do you suggest me to do ?

Thanks for your help

I tried rebooting, and that s what i feared : computer boots directly on the windows disk without loading the clover r4380 bios

i made a usb disk with clover r4871 EFI : the clover bios loads but not shows up any osx drive :s
does any one has an idea ?

little success
i made an unibeast installer, now the high sierra volume is seen, but it does not boot :
stays stuck on the apple at mid loading.
i guess that this is a version conflict between v4380 that is in the system, and the r4428 that is on the usb disk.
