With it, you can create a bootable media first, then boot your computer from it, and repair Windows by checking system disk and rebuilding MBR under WinPE environment. Before you proceed: Create a bootable USB drive: Plug a blank USB to a working computer, then download, install and run AOMEI Partition Assistant on that PC. Click the “Wizard” on the top side and choose “Create Bootable Media Wizard”. Type select partition 2 to select partition 2. 2 represents a number of the partitions discovered by diskpart. Type active to mark partition to active; Type Exit to exit diskpart; Type Exit to exit Command Prompt; Click Turn off your PC; Power on your PC; Method 2: Rebuild the Boot record. In the fourth method, you will need to rebuild the boot record.
Hi,
I accidentally deleted my windows 10 boot partition during some maintenance activities on my computer. So, now I do not see the Windows option on my PC in the UEFI boot loader. I do have CentOS 7 installed on an external USB hard drive so I booted into that and downloaded the Windows 10 ISO. I have created a bootable thumb drive using the ISO on CentOS using gparted.
So I booted using the thumb drive and chose the Windows 10 repair option but it did not help. I have 2 SSDs on my machine and I do not want to lose any of the data including the windows settings if I choose a fresh install option. My disk layout on Windows was:
C: - Windows was installed here. This is a 1 TB SSD Drive.
D: - Second 1 TB SSD Drive.
When I'm on Linux, then I can see those drives as 2 separate devices and I can also access the files on them. The device that corresponds to the C: drive still seems to have all the Windows installation data. If I boot into the Windows 10 thumb drive and select the fresh installation option then it lists all my partitions but I'm not sure which is which and I do not want to delete data by mistake. So, is there a way for me to fix the Windows efi records?
