please help. I dual booted Ubuntu with my Win 10. After a few weeks, I decided to delete ubuntu and try some other Linux distro. Well I deleted Ubuntu from my Win 10. But now when I start up my PC, it shows Grub Error: Partition not found. I googled it and tried to find solutions to it. Well, the solution that I found really likely to work was to use my Win 10 bootable USB. But after I installed Win 10 from my usb, I deleted all the setup files from my USB. So I need to make a bootable USB again, but I only have one PC, and because of the grub error I can't get inside of my OS. Please help me to restore back my Win 10.
PS. I am just a student, I really loved Linux and want to continue using it.
