[ubuntu] grub2 fails to load the hard drive

Hello.
I'll fast forward to the problem.
Ubuntu is installed on the hard drive in the laptop, and it is the only OS installed on it.
I'm using it daily, however, recently i had to run a program made for windows.
I've bought a new SSD, installed win10 on it, and successfully booted from BIOS (not UEFI), when coected to usb.
The problem arises here: I want to boot to windows from GRUB2, and only if SHIFT is held during startup (i.e. no interruptions if i don't need windows).
When i try that, update-grub2 gives me Windows10 loader on /sda1.
When it tries to boot it, it fails (no such device *UUID*, converting to 86, error).
When Ubuntu is loaded, the hard drive is recognized and it can be browsed within the file explorer.
The UUID is correct, so that's not the problem (i think).
Windows installation has its own bootloader on the exteal SSD, so it could be booted from wherever.
I'd like any input on this, i'm with the problem for last 8 hours, it's driving me crazy. Can't really see what to do anymore.
I tried repairing the grub, it was successful, didn't work (because there was nothing to repair).
When doing the ls command in grub2 command line, i'm only getting hd0 with 3 partitions, which is incorrect, because ubuntu is installed on ext4 with 4gb swap, and that's it.
Is it possible that it is reading the exteal hard drive incorrectly (as the 3rd partition?)

Here's some data:
