I have almost succeeded with a USB dual boot installation of Linux Mint 19.2 on a Win 10 laptop. I am a Linux virgin, so have followed the instructions in a "monkey-see, monkey-do" method. This served me well right through to the end of the installation in a live session. After receiving a completion message, I was invited to reboot, at which point the system froze. Any pointers welcome, but please assume (correctly) that I have no functioning knowledge of Linux. Baby step by baby step please.
Reboot the PC, select booting from the version of Mint you installed, and hold SHIFT to force the boot menu of GRUB to appear. Then, replace quiet where it appears in the commands for the first item in the GRUB menu with nomodeset, and then continue with booting. Here are two videos; the first is for the EFI/UEFI boot configuration most common with Windows 10, and the second is for the MBR boot process from Windows 7.
Once you get past that problem, you can install the drivers for your PC's video adapter.
