Boot problem after installing dual boot

I have Visual BCD editor to create dual boot on my PC. This seems to work fine, but I have made a huge mistake when I was installing Ubuntu as the second operating system. I configured Ubuntu as first boot option, and did not observe that the timeout was set to 0! It turned out that Linux would not boot, so now system is hanging, trying to boot into Ubuntu, and I don´t know how I can delete this boot entry. Can someone please tell me what to do. I can, off course, reinstall Windows, but that´s a major job, since I have a lot of applications. I do have a backup, but I cannot use the boot USB, which turned out to be defect!

Best regards

Ulf H.

    Post images or share links into this thread displaying the commands with results.

    3) In the left lower corner search type: msconfig > view system configuration > click boot tab > post images or share links into this thread

    For share links please use one drive, drop box, or google drive

    4) If you cannot boot to Windows then find a working computer and a flash drive that you can format (> or = 8 GB)

    5) On the working computer create a bootable Windows 10 or 11 iso:
