I just installed win10 + ubuntu on my Lenovo laptop. Windows is installed on SSD and Ubuntu is installed on HDD. sda1 is win recovery and sda2 is windows 10. Ubuntu is installed on sdb. Bootloader was instaled in sda.
Still, GRUB2 shows only win recovery on sda1. I already tried updating grub and os-prober as it was suggested in other asks (where windows was not found at al), but it only finds sda1. I read somewhere that it may be Lenovo fault, but i'm not sure about it.
Can i fix it any other way than manualy adding win10 in grub files? Various threads says that for win 8.1 and 10 can be buggy to add them manualy.
