HELP!
You were using Windows normally until you encountered a BSOD. After some days, your PC wouldn't boot and it reported missing a bootloader. You had a Linux bootloader ready for dual booting, so you installed it. Now you're using Ubuntu. To switch back to Windows without hassle, you'll need to reinstall Windows or restore your previous setup. Since you didn't install Ubuntu yet, you can try reinstalling Windows from the installation media or using a recovery tool.
You asked about fixing Windows issues related to the disk troubleshooter. It seems you experienced problems where the system tried to repair itself but gave unclear feedback about hardware or boot problems.
Creating a USB boot drive could help you access Windows or reinstall it. Since you're on Windows 7, look for Linux-compatible bootloader guides to set up a bootable USB. Even if you're unsure about your USB connection, checking both devices might clarify which one is active.
You can partition your Linux HD from within Linux itself. You don’t need Windows for this process. Once you finish partitioning, you can transfer your Linux system to the new partition using tools like GParted or GParted GUI. For moving files, you’ll need to back them up first and then use a partition manager or command-line utilities to copy the necessary data. The USB you’re using should be sufficient for now, but keep in mind its capacity may limit performance as you add more files.
