Question tried cloning OS from HDD to nvme SSD but i am entirely lost now

I've been working ALL day to get this to work but I have literally no clue what i'm even doing anymore and it's incredibly frustrating.

I have a samsung 960 evo which is 250gb and a 1tb 7200 rpm hard drive which i've been using for years as my boot drive but it's slowing down significantly so i wanna move windows 10 to my SSD.
At this point, i literally don't care about backing up or anything like that. I already had to delete pretty much all my games and files to make my HDD clone fit onto my SSD using a program called macrium. The HDD seems to be perfectly cloned onto my SSD with about 35 gbs to spare but when i set my SSD as my boot drive in the BIOS, it just refuses to boot. I feel like i've tried everything at this point but i don't know what's wrong.

Have you tried disconnecting the HDD so the SSD is the only option for the PC to boot from?

Yes, that was the first thing i did and it just told me that it needed me to insert bootable media. Did I miss something and not format my SSD before cloning to it or something?

Disconnect old drive and BOOT from Macrium Reflect rescue USB, there you will find option to fix boot problems.

Could you possibly give me the link to the macrium rescue thing? I can't seem to find it for some reason.

edit: nevermind i realize it's just on the program that i already have. I'm not sure how to create the usb rescue drive though :/

Insert a USB stick, start Macrium Reflect, go to Other Tasks tab, choose Create rescue media and it will create one for you.
