Somehow the EFI partition doesn't mount and it's impossible to troubleshoot via phone, she asked me to put back the old system 😞
People complain about all the invasive controlling bullshit Windows does. I haven't seen any kind of failure to boot issue with windows in a long time and I work in IT. Last thing I really remember being common in our organization was bitlocker getting triggered and people having to call in to get the key to unlock it, and that was back in the windows 7 days.
