Hey guys, so I have win10 installed on SSD and fedora 25 on HDD, i can launch both of them if i hit F12 and choose SSD or HDD, but grub2 cant find win10 boot, I tried to edit it with grub-customizer, tried with both /dev/sdb1 and /dev/sdb2 even /dev/sda3 and /dev/sda4, no luck, it cant find the drivemap. Os prober doesn't find it either. Here's the fdisk -l result, im out of ideas, hope someone can help.

if useing uefi, grub may require certain customizations. i do not think os prober works with uefi. Check out this post for possible solutions.

Sorry for late response, forgot about it actually. I havent managed to do it through manual install but when i just booted from usb in legacy mode and went with automatic install everything worked
