Can you directly boot Windows from UEFI boot menu, often f12, but varies by vendor. Same key you used to select USB flash drive to install Ubuntu. Grub only boots working Windows. So is fast start up/hibernation still on? https://askubuntu.com/questions/843153/unable-to-mount-windows-10-partition-it-is-in-an-unsafe-state & https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation Or does Windows need other repairs from a Windows repair flash drive? — oldfred, Jul 04 '22 at 15:19
