HI,  
I am trying to install Ubuntu 22 for dual-boot with Windows 11 Pro.  
I downloaded the Iso image of Ubuntu 22, and I used Balenaetcher to create the bootable flashdrive. I thought it would be simple and quick and easy but it is failing.  
I opened Balenaetcher, I selected the Iso image, the USB drive was automatically selected, and then I “flashed” it. I tried it once with a small tight USB drive, and I got the error “You need to format the disk before you can use it”, and “D:// is not accessible. Volume does not contain a recognizable file system”.  
When I tried loading the system to install after restarting, I got the message, media not detected.

What is happening? Why my USB drive is not detected?  
I did it again with a regular flash pen, I moved my files to my laptop, and then I flashed it again, and I got the same problem.
