Tonight I was installing some updates on Windows 10. My computer just shut down during the installation and when I opened it again, grub rescue> appeared. I tried to use ls and change the prefix to the right partition, but it says "Filesystem unknown" for all partitions. Also when I run set, it says that the root partition is (hd0,msdos6) which does not appear in the list when I run ls. It shows only the partitions from 1 to 5.
I just want to enter Windows. How to act next?
