recently I've installed manjaro kde alongside my windows 10.
my windows location is on dev/sda2 location. but grub use this instead dev/sdb1 maybe long time ago i had a windows 7 on this partition but i want to select windows 10 instead.
used grub update command and i got this on grub GUI windows 7 boot

savedefault
insmod part_msdos
insmod ntfs
set root='hd1,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
  search --no-floppy --fs-uuid --set=root --hint-ieee1275='ieee1275//disk@0,msdos1' --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  7812ECF212ECB5F2
else
  search --no-floppy --fs-uuid --set=root 7812ECF212ECB5F2
fi

Does it boot into win10 with the win7 boot entry?

try GRUB customizer in manjaro

Does it boot into win10 with the win7 boot entry?

no, it will show a message that your boot is corrupted try to fix it via your windows cd.
tried grub customizer but it just show win 7 instead of 10

If you edit the boot entry on-the-fly, does it boot to Win10?

And as suggested above, try "GRUB Customizer".

if i had known how to edit with Grub Customizer then why should I ask it here?

You're saying Grub menu contains wrong partition for your Windows setup. With Grub Customizer, it's easy to edit this entry. You can even duplicate it, and change /dev/hda1 to /dev/hda2 (or whatever the difference is), save and reboot.
