[SOLVED] Migrating to a new system, can't find the EFI partition

Hello everyone, after upgrading motherboard and cpu I'm trying to follow this guide Migrate installation to new hardware > Top to bottom to get archlinux to boot again. I skipped sections 3.1 and 3.2 as I'm keeping my old drive, and got stuck at mounting the filesystem: I don't see an EFI partition for the linux file system...

I have a dualboot with windows. Here's the output of fdisk -l:

Device           Start         End     Sectors    Size  Type
/dev/sda1         2048      923647      921600    450M  Windows recovery environment
/dev/sda2       923648     1126399      202752     99M  EFI System
/dev/sda3      1126400     1159167       32768     16M  Microsoft reserved
/dev/sda4      1159168  1258356341  1257197174  599.5G  Microsoft basic data
/dev/sda5   1258356736  1259448319     1091584    533M  Windows recovery environment
/dev/sda6   1259450368  1267838975     8388608      4G  Linux swap
/dev/sda7   1267838976  1952438271   684599296  326.4G  Linux filesystem
/dev/sda8   1952438272  1953521663     1083392    529M  Windows recovery environment

I don't recall how I designed these partitions (it was years ago) but I'm surprised not to find a second EFI partition, I'm quite sure I had UEFI already before upgrading. I'm thinking maybe one of the partitions labels is wrong? Is there a way I can check if one of the "Windows recovery environment"
is in fact the EFI partition that I'm looking for? Or am I missing something?

Note: after upgrading I've been using just Windows for a few months

One ESP is enough. Why should there be another one?

I don't see an EFI partition for the linux file system...

You don't need a separate EFI partition for Linux. There is only one holding all the efi binaries.

Edit: One second late...
