I have a dual boot machine (Ubuntu18.04 and Win10). I accidentally formatted a partition in the disks app in Ubuntu. When I restart the computer, grub still shows a windows manager option(where I usually boot into windows); however, this time there are a few errors.
1."no such devices: 66E1-C5F0"
2."file /efi/Microsoft/Boot/bootmgfw.efi not found".
- I have tried start-up repair using a win10 bootable usb but it did not work. I do have access to the windows command prompt.
- I know the partition I had formatted wasn't the OS partition nor the Recovery partition.
- I am still able to boot into Ubuntu.
Is there anyway to restore my win10 or do I have to install win10 altogether? Thanks in advance!
