Такая же проблема, только ОС не ubuntu, а на основе нее kde neon lts (kde 5.12) и вместо ssd - жесткий диск 2,5 на террабайт. Смарт также отличный. Windows стоит на отдельном диске, подключается по питанию в замен диска с kde neon и обратно, когда надо.
Слетает загрузчик, уже 2 раза ставил систему. В биосе видится диск, но без выбора загрузчика kde neon, тупо диск и все. Установливал ОС с efi загрузчиком.
Хотел восстановить загрузчик, но толком и непонятно - везде по разному пишут об восстановлении efi загрузчика. Единой инструкции нет.

Вроде все хорошо. Но почему? Почему постоянно пропадает загрузчик.
