After installing Ubuntu, can't boot Windows 8 at all!

I had Windows 8 running and then tried dual boot. Once Ubuntu was installed, Win 8 wasn't showing up in my GRUB loader, also not in the original laptop Boot Loader (Windows Boot Loader? - from there I can start towards ubuntu too).

I tried more or less all methods proposed in GRUB does not detect Windows as well as in similar questions (sorry to "ask again": solutions proposed were not succesful in my case), inclusive boot-repair: here is the log: https://paste.ubuntu.com/p/6vFGKFKpbH/

Still not able to find Windows 8 in GRUB after that (only ubuntu). Looks like os-prober can't detect windows on my /dev/sda2 partition. Any clues ?

Here is how my partitions look like:

Disk sda: 931.53 GiB, 1000204886016 bytes, 1953525168 sectors
Disk identifier: 0xe8d8a8f3

sda8       1889679360 1897490431    7811072   3.7G 82 Linux swap / Solaris
Partition table entries are not in disk order.

sda2 with 842.5G doesn't sound right...

Where is the issue? Thanks in advance for advice!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
