Overall it's of course no big deal but Im still confused as to why it doesn't see the mounted iso of the update when booting from the USB.
And I've tried unarchiving the iso and also just looking inside but it just shows up empty (I've checked multiple times that it downloaded correctly and even redownloaded it a few times just to be sure). Do I need to convert to img or something first? The size is still showing correctly, so I'm unsure as to why it's empty in every case.
Thanks for trying to help so much!
I'm at a total loss here, as I've never had an issue with a BIOS iso before. Perhaps it's only visible on Windows, or they have protection in place? Could also be negligence and they don't care anymore as this is a relatively old model (though I've just bought it as I was looking for a good deal on my first proper work laptop ๐ )
