Slow windows boot

I just finished Installing mac os Catalina on my MSI-GL63 9SDK. I moved the windows installation from my SSD to a partition on my HDD and installed mac os on my SSD. mac os boots really fast but when I try to boot windows I am not able to find the option to boot from my HDD. Instead I have to use the windows option in my opencore bootloader but the boot time is really bad. It takes forever to load and even once I login it takes about 15 mins to come up to speed. Please help specs below Laptop: MSI GL63-9SDK processor:i7 9750h Ram:16gb SSD:256gb HDD:1tb Graphics:GTX 1660ti
