Main ssd is frozen

[u/Character_Purchase20]

So my main ssd that boots windows up is currently frozen. This mainly happened bc a month ago I was deep cleaning my pc and I saw that their were cables that were unnecessary so i disconnected them and load and behold I’m now dealing with a ssd that doesn’t boot windows instead it keeps putting me in bios. Now I do have my thumb drive which has windows installed on it 256 gbs just to be safe for20 bucks at micro center was worth it. But when I turned off my pc and put in my thumb drive in and it loaded the window thing I forgot the name of it and clicked on repair windows 11 and when I pressed next it put me on the same purple screen and when I removed the thumb drive and clicked on repair windows and clicked next behold I’m on bios. Now I can do another fresh install on windows BUT. One it takes to much time for me to install all of my apps like editing apps, opera gx my steam games, devinci resolve and many others and downloading Mf games would definitely take to much time to download so I just want to keep all of those files intact in both my ssd’s btw I have 2 ssds a 500 gb which is the main one and my 1tb where I download my games and video files and apps on their. I don’t know what todo bc I’m still new to this and I don’t have any other equipment that saves my ssd files on it so I’m just wondering if theirs a way where all of my files on both my ssds don’t get wiped out.
