Boot selection unavailable

[plrll]

Hello everyone, I installed Xubuntu(most recent LTS) to dual boot with windows 10 and the installation was successful, however when I restart the system is booting directly to Xubuntu.
I read here that the system will show the boot menu to allow me to choose the OS I want to boot but that is not happening.
If I want to boot win10 I have to press F12 at boot.
I have tried the boot repair tool and I do not understand the Boot Info Summary so I have not done any repairs yet.
Here is the Boot Info Summary link: https://paste.ubuntu.com/p/4pHHVmNnRp/
Can anyone help me understand this and is repairing recommended?

Your grub file needs a little edit.
Boot into Xubuntu
Open a terminal and enter:-

sudo nano /etc/default/grub

Enter your password

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=menu #originally hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

ctrl+o to save and ctrl+x to exit

sudo update-grub

Reboot
Any good?

Nope. After reboot it is still booting to Xubuntu without showing any menu.

Whoops, I forgot OS_PROBER
Add this line to /etc/default/grub

GRUB_DISABLE_OS_PROBER=false

Then sudo update-grub and reboot
The terminal output from sudo update-grub should find Windows Boot Manager.

Update: Reparing with boot repair did not Unhide GRUB boot menu. I'll try contacting the devs.
If anyone would want to review the boot info file here are the links:

after ansarabbas8273's method and recommended repair with boot repair tool: https://paste.ubuntu.com/p/Bj7B5vfDWR/

Thanks everyone for sparing your time to help.
According to the device(thinkpad x1 carbon 3rd gen) manufacture, I'll have to keep using F12 at boot, that is until I don't need win10 anymore.
I will keep the thread open for sometime then mark it as solved.

After you ran sudo update-grub, did you see terminal output to confirm that Windows Boot manager was found:-

Yes it was found but the boot device menu with with timeout is no show.

Yes it was found but the boot device menu with with timeout is no show.

That's a little bit of progress.
Do you have Fast boot or similar in your UEFI settings?

Try this

sudo nano /etc/default/grub

Add this line to your /etc/default/grub file, right after the "GRUB_TIMEOUT=" line

GRUB_RECORDFAIL_TIMEOUT=10

Save and exit. The update grub to pick up the changes

sudo update-grub

Reboot and test...
