Hi everyone! I'm a total newbie and could really use some guidance. I recently installed ChrimaOS on an old HP laptop to turn it into a media PC, but I think I've messed up and realized it's not the right system for me. I want to get back to Windows 10 since that's the only version my laptop supports. I have a USB flash drive with the Windows installation on it, but it's not showing up in the BIOS boot menu. Plus, every time I try to access the BIOS, it crashes. I'm feeling pretty lost here! Can anyone walk me through the steps to get back to Windows 10? Did I miss something crucial with setting up the USB? I'd really appreciate any help!

First things first, you need to ensure that your bootable USB drive is set up correctly. It's usually more reliable to create the USB on a Windows machine. If you used a Linux system like Ubuntu to create it, you might run into driver issues when booting. Try making your bootable USB with the Windows Media Creation Tool if you have access to a Windows PC.
Also, when you get into BIOS, you should disable Secure Boot and enable USB boot support. Navigate through the BIOS settings carefully—there should be options like ‘USB Boot’ or ‘Legacy Boot’ to select.
You might also want to ask for help in a Windows-specific forum. The Linux community may be limited in terms of supporting Windows installations since many enthusiasts prefer Linux. It could be worth looking into dedicated Windows support groups for targeted assistance.
If you're still having trouble, consider using Ventoy to create your bootable USB. It's super easy and can often solve the 'no media driver found' error. Just download Ventoy, run it to set up your USB, and then copy the Windows ISO file straight onto the drive. After that, reboot and check your BIOS settings again.
I haven’t tried Ventoy yet, but I’ll definitely give it a go! Thanks for the suggestion!

Thanks for the tip! I had similar issues and found that changing the boot order in BIOS did the trick for selecting my USB.
