I'm trying to install EOS 6.1 as a dual boot alongside Windows10 on my laptop. I've already space on my SSD for EOS; I have 40GB formatted ext4 for root, 8GB for swap, and about 140GB ext4 for home.
I used the custom install option, and set the root, swap, and home on the respective partitions (sda7, sda8, sda9). Looks like my sda2 is where the efi system partition is; it was initially 256MB, I expanded that to ~540MB before starting the installation (it is flagged as esp and boot on gparted). Since there was no option to "use" this partition as efi/esp, I didn't touch it, thinking EOS would detect it automatically. However, I'm running in to this error:

ERROR: configuring bootloader error: command failed with exit status; exit status: 1

I'm not sure what I'm doing wrong. I've disabled secure boot and enabled legacy boot so that I can boot from the usb. Win10 continues to load fine. My Win10 partition is sda3, and sda4 through sda6 are system recovery partitions; didn't touch them. My system is a Intel Core i5, with a 16GB ram, and 512GB SSD.
Any help much appreciated! I'm not a very tech-savvy user. Thank you.
