I installed Ubuntu as a Dual boot, the webcam did not work so I tested several solutions that I found on the web, when they failed and I made a restart to the OS, I got a message /dev/sdb7: recovering journal ..., so I wanted to delete all the partitions I allocated for the Ubuntu and reinstall. After deleting all the partitions except the partition where the operating system (C) is installed and the partition labeled EFI, I restarted the computer and it showed me that Windows Boot Manager is missing. (I had some healthy partitions that I only could delete them using Powershell, when I right click on them in the Disk Managemnent it only showed help, those partitions I have not allocated by myself, I took the risk and delete them.)
I followed this: https://answers.microsoft.com/en-us/windows/forum/all/accidentally-deleted-windows-10-boot-partition-how/181745f9-3303-4968-9851-5c213db9c89c
Now when I run list disk in DISKPART then it shows me two disks:
Disk 0, which is the SSD on which the operating system is installed.
Disk 1, which is - USB Flash Drive that contains the installation media.
Running select disk 0 lets me select it.
In the list partition step, I am presented with:
Partition 1 System 100MB
Partition 2 Primary 446GB
Partition 3 System 515MB
Partition 3 is the add-on of create partition efi
Running bcdboot c:\windows gives:
Failure when attempting to copy boot files
I tried to launch Ubuntu from USB flash drive, in the Ubuntu installation type, I choose Something else it shows me that the EFI partition that I had not deleted is Windows Boot Manager so I don't understand what happened.
How do I restore Windows Boot Manager to boot the existing SSD and get back an access to Windows OS?
Thanks.
