If windows is present, you should be able to select at startup during the grub.

You don't precise which version you are working with so I add this comment :

I noticed with ubuntu 14.04 (maybe 15.04 too), grub may not appear. If grub not appear edit file "/etc/default/grub" and comment "GRUB_HIDDEN_TIMEOUT=0".

You should now have something like this :

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Then update grub :

sudo update-grub2

Finally restart your computer and you should be able to select another system.
