4.15.0-43 не загружается?

Вчера мой компьютер, внезапно разрушенный. С тех пор начальная загрузка зависнет на фиолетовом пустом экране при попытке загрузиться со значением по умолчанию 4.15.0-43. Однако, если я запускаю Меню Личинки и выбираю 4.15.0-42, все хорошо работает.В чем проблема?

Вот мои аппаратные средства:

• Intel Core i7 7700K 4x 4.20GHz
• MSI Z370-A PRO Intel Z370
• DDR4-2400 DIMM НА 32 ГБ
• MSI на 8 ГБ GeForce GTX 1070
• Samsung 860 на 1000 ГБ SSD
