Given that I have installed both Windows 10 (primary) and Linux (secondary) in my disk, is there a way to boot into Linux by option inside Windows 10, maybe using 3rd party software?
I want to use the Linux installation rarely. As a result I don't want to have the bootloader screen delaying my boot by even a second. I can't use a VM because I'm running programs that make use cuda.

You can use EasyBCD to tweak windows bootloader.
Install EasyBCD (Visual BCD Editor/ Bootice/ DualBoot pro all these are third party software which can be used for editing windows bootloader) and add entry for GRUB2 (which is the linux bootloader) to it and rewite mbr.
Then restart and boot into Linux OS.
Edit the grub file
(most probably /etc/default/grub or will be /etc/grub.d folder)Change
GRUB_TIMEOUT to 0and then execute commandsudo update-grub.
Hope this may help. I Have used this method earlier in my system.
(EasyBCD 2.3 works with Windows 10 also)
In ubuntu, you just have to edit your GRUB configuration files.
- Open your Terminal with Ctrl+Alt+T
- type
sudo gedit /etc/default/grub, press Enter and type in your password. Your grub file will (most likely) look 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=""- Change
GRUB_DEFAULTto the number of your Windows OS in the bootloader list. Don't forget to save. (Note: the list starts at 0, then 1, and so on..) - Then, run
sudo update-grub. You computer should automatically boot to Windows 10.
If you need to open the bootloader in order to use Ubuntu, hold Shift key while your computer is loading your bootloader.
