    Hello friends,
    I was using Windows 10 thru Parallels Desktop 19, it worked but, at one point it stopped responding, I shut it down, and ever since after - when I try to launch it, it once said "operating system is not found" and opened the BIOS where I clicked continue, but now every time I launch it, it just opens the UEFI shell, please help. My specs: MacBook Pro 2016 16GBRAM, Intel Core i-6700, AMD Radeon Pro 450 (2GB), macOS Monterey, and Parallels installed onto an external HDD (b-cuz not enough space on integrated SSD). Please help. Is there a way to backup data and move it to a new VM if this corrupted (because I don't wanna install GTA V for 6 hours again lol) or it would be even a lot better if I'll be able to make it work again, I spent countless days installing and setting up everything there, troubleshooting, so I really don't wanna lose everything.
    Please help guys,
