cryptn Hi, What is your problem?
I wasn't able to boot anything (Solus or Linux). I resized the Solus EFI partition properly and reinstalled it to fix the solus boot. I wasn't able to boot into windows because although efibootmgr listed Windows boot manager it wasn't present from the boot menu of the laptop.
For Windows I did the following steps (it worked but maybe there are better solutions).
-I created another EFI partiction (100 MB) for windows (beacuse I lost it)
-From a live usb with gparted I flag the Solus EFI Partition as a data partition (i removed the /boot and /esp flag) because when i was trying to recover Windows with the Windows iso it wasn't able to distinguish which one to use
-I booted with the Windows ISO usb and then used bootrec commands from cmd.
-With gparted I flagged with /boot and /esp the Souls EFI partition
Now I can boot into Solus or Windows.
