Both sda1, sda3 look like EFI System Partitions, though it's impossible. I think sda1 is ESP for sda2 "recovery" OS, and sda3 is ESP for sda4/sda5 "windows" OS, and if I power my laptop using "assist" button, the recovery ESP kicks in and starts the "recovery" OS (which is windows recovery mode). If I power on using the power button, windows starts as usual.
