Grub2 and Windows 7. Infinity War

Question

Windows

Good afternoon habr, I don’t know who to ask and where to turn, so I hope for you.
In general, fdisk -l: / dev / sda5 - Windows 7 sudo update-grub2, etc. Does not help. Rough just doesn't see hard with Windows. grub.cfg: Pastebin.com Thank you very much.

You simply do not have an entry for Windows in the grub config,
find the uuid of the partition with Windows
ls -al /dev/disk/by-uuid/
numbers opposite /dev/sda2
add
menuentry "Win7" {
insmod part_msdos
insmod ntfs
set root='(hd0, msdos2)'
search --no-floppy --fs-uuid --set what_found
chainloader +1
}
and then
sudo update-grub2
