I've Installed Ubuntu in dual boot with Windows10 and at first I had a problem with GRUB not showing at startup but I solved it with renaming files in Windows with help of this question.

Now works at startup and shows me these options:

GRUB

But when I select 'Windows Boot Manager (on /dev/sda2)', Timer below just resets and GRUB reappears, it doesn't let me boot into Windows.

But I can boot Windows if I select 'Windows Boot UEFI Loader' (Option 4 in above image).

Is there any problem here? Is this supposed to work like this? According to me it should load into Windows with Windows Boot Manager but it doesn't. What should I do?

Any help is really appreciated.

No.

no issue here.

Windows UEFI bootmgfw.efi

and

Windows Boot Manager (on /dev/sda2)

are deprecated leftovers from file renaming.

The correct option is :

Windows Boot UEFI Loader

You can clean up and reorder your grub using this tool : grub customiser.

or completely reset your grub using ths tool boot repair

I personally recommend installing both just in case but only using grub customizer to remove the extra windows entries.
