Back when i first installed ubuntu,all was well,whenever i would start my computer,i'd see my boot options,windows and ubuntu,then choose one,but recently,the boot menu hasn't been showing up,whenever i start my pc it boots ubuntu straight away with no options menu.

I suspect this is because i disabled Secure Boot,since it started happening when i disabled it,since i did,every time i boot it says "Booting in Insecure mode",is this the cause?If so,how can i re-enable it safely?

To force a grub menu, you should edit the file /etc/default/grub and modify options:

GRUB_TIMEOUT=10
GRUB_TIMEOUT_STYLE=menu

And run

sudo update-grub

You may use grub-customizer too.
