During the software update debconf-communicate window (configuring grub-efi-amd64-signed) showed up asking me to select the grub location. I researched but didn't find a solution online for what I should choose. I ended up choosing the SSD with the boot/efi but the next window it wouldn't continue (there was a check box saying continue without installing grub). So I went back and marked both SSDs and pressed next. Now it shows me window saying the installation of the software failed. I hope it didn't mess up my Grub loader; I have a dual boot system for Windows and ubuntu Linux.

The target for installing EFI GRUB must be an EFI System Partition, not a disk. GRUB does not a priori know whether the device you've specified is correct.
The value of this field is supposed to have been populated for you by the installer at install time. So I don't think there's much here we can do to improve this, aside from the error message presented by the postinst ("/" is not the name of an ssd).
