Hello all, I recently installed ubuntu on a seperate partition than my windows 10 install. Even though Ubuntu works well, I can no longer boot into Windows. It doesn't even give me the option to boot from that partition from the BIOS.

I did NOT follow a dual boot guide.

Here is a screenshot from my partition list in Ubuntu: https://imgur.com/a/PZFk0yQ

Not sure what to do. I also have a USB for installation media.

Have to say this, but you should really have followed a guide. Did Ubuntu see your Windows installation? If no, we'll restart. Back up all the stuff, specially on Ubuntu however a full image would be fine here, can do with a bootable Macrium Reflect USB.

Also download Windows and Ubuntu ISO's and burn them to separate USB drives.
Make sure you have Safe Boot and Fast Boot off.

Boot into Windows USB and rebuild BCD. Note that this will make you able to boot into Windows but not Ubuntu.

After booting into Windows download and install EasyBCD. Linux tab>Ubuntu>Automatically find and load>Add entry. This should add the Ubuntu option to your Windows boot options screen. You can keep this like that, if you ask for it, or try to switch to Grub bootloader.

Boot into Ubuntu Live USB and try this:https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows
This should rebuild the Grub and make it see Windows. If not, reinstall using a guide.
