Grub is preventing me from booting from usb to install Debian

I had Linux Mint on dualboot, but I was having problems with the audio, so I deleted the partition using disk manager on windows 10, and was going to install Debian, but when I try to boot Debian from the usb, it goes to GRUB and I am unable to get past this. I tried many solutions on various forums and none of them have removed this obstacle. Anyone got any ideas?
