Windows 10 doesn't load from GRUB Menu

in flag

I'm working with Ubuntu after a really long and extended period of time. When I installed Ubuntu, I did it side by side the windows installation. However, on the grub screen when I click on Windows, it says it cannot find the windows distribution.

I am however able to load windows if I repeatedly tap F11 on the keyboard at the BIOS and then manually select it from there.

What can I do to fix this?

EDIT - Here is what the entry for Windows 10 looks like in Grub.

insmod ntfs
set root='hd1,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
  search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  040E12DF0E12C996
else
  search --no-floppy --fs-uuid --set=root 040E12DF0E12C996
fi
parttool ${root} hidden-
drivemap -s (hd0) ${root}
chainloader +

Here is an image of what my disks app looks like.

If Ubuntu and Windows are installed in the same boot mode, UEFI mode or BIOS mode (alias CSM alias legacy mode), `sudo update-grub` in Ubuntu should create a working boot alternative for Windows in the grub menu. But if they are installed in different modes, the method that works for you is probably the best alternative.

I think the boot mode is different. There seems to be 2 separate partitions. How do I link the 2nd partition (windows) to the GRUB boot loader?

`sudo update-grub` can see all partitions. But it does not help if Ubuntu and Windows are installed in different boot modes. If you really want Windows in the grub menu, it is probably easiest to reinstall Ubuntu in the same boot mode as Windows (if Windows 10, and factory-installed, UEFI mode), but I would not do that, I would live with the system as it is now.

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.
