Persisting Corruption Issue

Hi,

My entire computer has been a bit of a mess for a while. I have dual booted Windows 11 and Ubuntu. I have been favoring Ubuntu for a while but I recently needed to use the Windows operating system. Regardless, there seems to be a fair bit of corruption present. When I attempted to use disk management to shrink my C: partition and I was informed that it may be corrupted, and was thus unable to shrink it. I used "ctkdsk C: /x /r" to try and repair it but all that yielded was a message about scanning and repairing the drive on boot. Further usage of the tool indicated that repair was needed but restart after restart no changes were made. I was still unable to shrink the volume so I tried "sfc /scannow" this did find and fix files (when I ran it a second time the output indicated no malformed files were found); still shrinking the volume was impossible. Even though it is not very applicable, I was desperate and did "Dism /Online /Cleanup-Image /CheckHealth" which unsurprisingly told me my image was not corrupted. If there is anything else I should try before completely resetting the system please let me know.

Hi, thank you for replying. The link you have provided seems incomplete. Is there a chance that you can share it again? Moreover, based on the error you have, I recommend running a custom installation to fix the issue, however, the process will delete all apps but will retain all files on the PC, If you are okay with that, you may follow the steps provided below:

We need another PC and a USB drive (At least 8GB and make sure there are no files inside, as it will reformat the USB) Once you have that, kindly follow the steps:

To Create Installation Media:

Go to the Windows 11 website: https://www.microsoft.com/en-us/software-downlo...

Under Download Windows 11 Disk Image (ISO) select Create Windows 11 Installation Media.

-After downloading, run the media creation tool. You need to be an administrator to run this tool.

-If you agree to the license terms, select Accept.

-On the What do you want to do? page, select Create installation media for another PC, and then select Next.

-Select the language, edition, and architecture (64-bit) for Windows 11.

-Select USB.

To do a custom installation:

Once done downloading Windows 11 to the USB, kindly follow the steps below:

    Apologies for the malformed link. Regardless the link to the forum covered the same solution as the one you provided. It proved effective and my partition is now pleasantly smaller thank you for all your help!

    Hi Bernard,

    Unfortunately doing an upgrade in place with the ISO ran into it's own issues. After going through seemingly the correct process after one reboot and login I was confronted with this screen. I went through some of the typical trouble shooting methods that I had not already done: detaching USB cables (excluding power) and also I ensured the system time was accurate as some articles sited that as a potential issue. But after a few repeated attempts of this I was still met with the same screen each time.

    I found other trouble shooting recourses but some involved regedit which I did not want to use without knowing it was necessary. I also found this post about creating a bootable repairing USB on this forum but I figured I should consult you beforehand to ensure this is a good path forward.

    Also not that I anticipate it being applicable but I just wanted to clarify that I already have functioning Ubuntu and Windows partitions present but at some point the Windows one encountered issues. So in regards to partitioning I think all I want to do is shrink the windows volume when possible and leave the rest of my partitioning table unaltered.

    Thank you for helping me with this annoyingly technical issue.

    Hi, thanks for reaching out. My name is Bernard, a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.

    I understand the issue you have, there is nothing to worry I am here to assist, Based on your inputs, the Drive C: is unable to shrink due to that it may corrupt and unable to boot as the Windows OS is installed to that partition, you may shrink it but in a small amount of storage only, what I recommend is to delete all the OS first, then create a partition you want to Ubuntu and Windos again, by that you can avoid any corruption on the system.

    Moreover, you can try to run a system repair to make sure that there is no corruption in Drive C: kindly follow the steps below:

    I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

    Kindly follow the steps from this link:

    https://answers.microsoft.com/en-us/windows/for...

    Once done, try to shrink the volume again, however, if the issue persists, it is better to re-create the partition before installing the OS.

    Let me know how it goes and I hope that helps.

    Bernard
