I have a computer at work that runs Linux. I haven’t ever messed with Linux before, and the person that used to run this computer doesn’t work with us anymore. I need to swap it from Linux to Windows 11, but whenever it turns on I just see a screen that has the words “(initramfs) ls” in the top left and a few rows of other Linux jargon I don’t really understand. The problem is, I need to back up all my files before swapping OS. What should I do?
