I'm new to this, and I tried following some tutorials, but it didn't work very well. I have a sister in the programming field, and she needs to install the Linux system, and they recommended using Ubuntu, so I did some research on how to install and download another application, balenaEtcher, to help. To do this, I need to use a ‘pen’ ‘drive’, and I did. One with 100 GB. I tried it first on my personal computer, and it worked fine, but the pen drive became unusable afterward, so I formatted it using CMD and emptied it completely, it looked brand new and ready to use. But, when trying to do the procedure on my sister's computer, it says that I needed to format the pen. I formatted it again, about 2 times, and it always did this. I don't know what it could be, I don't want to use another pen to "ruin" it.
If you could help me, I would appreciate. Thank you and good day for you.
