I have 2 partitions on my SSD and I have installed Fedora 34 and windows 10. Everything was working fine, but now when I boot into windows 10 it black screens after Lenovo logo (using a lenovo laptop btw) for a few seconds and shows the grub boot menu again. First time trying out dual boot, absolute beginner please help me out

You could try 'boot-repair-disk' and burn it on a CD or thumb drive. Used it a few times to sort out one or other OS not booting on a dual boot system.
Boot into Fedora and run this in the terminal to update Grub.
This command has to be ran as 'root'. So become root first than run this command:

grub2-mkconfig -o /etc/grub2.cfg

Than reboot and see if you can boot into Window 10.

If that fails than you probably will need to perform boot-repair.
