Well, in the end it was my SSD (where windows was installed).0 It got corrupted data and whenever I tried to boot with windows usbs (3 in total with 3 different methods) it got stuck. And the reason for that was bootable win usb instances are always checking if there is a windows installed. Because my SSD was corrupted, it got stuck without showing anything. All that for that repair button.
**If you want to save your datas, Ubuntu bootable usb allows you to try ubuntu without installing it to your drivers. So basically, you run Ubuntu from USB.**
**If you have problem opening your disk from Ubuntu even if you see them:**
Open terminal and write
sudo fdisk -l
to list disks, /dev/sda1, /dev/sdb2, etc.
sudo ntfsfix /dev/sda1
Will allow you to open the disk from file manager. If not, try restarting.
**If even with reaching the disk, you can't seem to be finding your files:**
I was mainly looking for my Baldur's Gate 3 saves (77 hours I have put in for that character ) But they were not in the folder. So for that you can search from terminal with
find /media/mydisk1 -type f -iname "*.lsv*"
lsv is the extension for BG3 save files. You can write anything you remember from the files you are searching `*` characters allows to find similar texts.After searching, found files would be stored in a folder, like `found.000` which will be in that USB you booted Ubuntu from. Now you can copy those files even though they are not visible in file explorer/manager. And they work.
