Help needed about removing a partition in DMDE
Hello. I own an ASUS notebook running Windows 10 with two partitions (C and D). I attempted to transfer the contents from partition D to C using copy and paste, without realizing it wasn't the correct method. As a result, the computer won't boot. The next day, when I tried to start it, I got the error "an operating system was not found." I created a bootable USB with Windows 10 to perform a repair, but it didn't work. I opened CMD and tried several online methods to get the PC running again. Eventually, I managed to run DMDE.exe through the command prompt, but I'm stuck there. I've attached some pictures showing the steps I took. I'm asking if anyone can assist in fixing my PC and restoring it to the original partitions. I noticed the two partitions are healthy, but it's possible that the OS was on D before moving the data to C, which might have caused issues. It seems the data is still present, even if I don't know the exact details. Please be patient, as I'm not very familiar with computers. I appreciate any help you can provide.
Never attempt that action.
You transferred bootloader files between partitions.
The bootloader is corrupted and the system won’t start.
Repair the bootloader next.
Use Windows installation media to boot and run these steps:
diskpart
list disk
select disk 0
select partition x
(select 931GB disk)
list partition
select partition C:500MB partition, this is the bootloader area, replace x with a valid number – likely 1)
active
list volume
note drive letters for all volumes (your screenshots show E: - 500MB bootloader and C: - 931GB OS partition)
exit
bcdboot C:\windows /s E:
Boot files created successfully.
You should be able to start Windows afterward.
Hey! After six months, my PC is finally working again. Thanks a lot!
You might want to exclude the drive letter from the bootloader partition, to avoid unnecessary changes. This task is available in Disk Management. Click right-click on the 500MB partition and select "Change drive letter and paths," then remove the linked drive letter.
