Boot-Repair hangs, possible alternative?

My overall goal is to dual boot Linux Mint and Windows 10. The motherboard is legacy bios only. Firstly I installed Linux Mint then Windows 10 on a secondary partition. Because I forgot to make a separate boot partition... I moved everything 1000MB to the right, and created a ext4 boot partition at the beginning of sda. Running boot repair on a live Ubuntu USB with the options: - Separate /boot partition: sda4 (the first partition on disk) - GRUB Legacy (figured that was for legacy bios) - Reinstall GRUB (default) - Unhide boot menu: 10s (default) Boot Repair hangs at Purge kernels then reinstall last kernel sda1 (ins). This may require several minuets... I have let this running overnight, the process is still running. I have done a reboot and tried again, let the process run for 3 days. Nothing different.
