Windows 11 ran into a problem and fails to boot after resizing c partition

Dear Microsoft Support Team,

Hope you're doing well.

My laptop is of type lenovo loq which comes with/ I bought with an original windows 11 home edition.

I was trying to extend c partition (on which operating system is installed) in my laptop using and I managed to resize it using a software called aomei.

As one of the screenshots attached shows c partition before resizing doesn't have the unallocated free space next to it in the right which I shrieked from the D partition next to so that the extend volume option was greyed out and not selectable so this is why I used the software mentioned above to resize the C partition.

After I did that the software asked to reboot the PC in windows PE mode as it does this operation in this environment. The problem is that after rebooting windows ran into a problem (blue screen) and then gave me the menu in the screenshot as it fails to boot again, so can you please help/support me in this issue.

Thanks in advance.

BR,

Islam

    Hello,

    Thanks for reaching out here in the Microsoft Answers Community.

    Based on the screenshots, it seems that the tool you used has changed the layout of the drives that prevented Windows to boot.

    Please note that you cannot change the starting position of a partition, so you cannot extend the C drive without deleting the D drive.

    Based on the situation, please do not reset the computer. Instead, please select "Command prompt" from the menu, and run the following commands to let Windows boot.

    mountvol A: /s

chkdsk A: /F /X

chkdsk C: /F /X

chkdsk D: /F /X

chkdsk E: /F /X

    This mounts the EFI reserved partition to drive A, and checks and repairs the 4 partitions.

    Disclaimer: Running "CHKDSK" can check the file system and file system metadata of a volume for logical and physical errors.

    To avoid any trouble for you, do not cancel or interrupt CHKDSK, and back up important data.

    dir C: /A

dir D: /A

dir E: /A

    Check which drive is the WIndows system drive. You can deduct from the volume label, the size, and the files at the root of the drive.

    bcdboot C:\Windows /s A: /f UEFI

    Create a new UEFI boot entry. Change "C:\Windows" to "D:\Windows" if the system is in the D drive, or "E:\Windows" if it is in the E drive.

    After that, close the terminal window and reboot the computer. See whether Windows can boot.

    If you can boot Windows, to extend the system drive, you have to delete the D drive (and optionally, the E drive). Please copy all the files of the 2 drives to offline storage (like USB sticks, external hard drives, and memory sticks) beforehand to prevent data loss.

    Feel free to post back if you need further assistance.

    Best Regards,

    Hello Sheng,

    Thank you very much for your quick feedback and support, yes i understand that the tool i used caused changing in the begining and end of the locations for each partition in the disk which caused the windows fails to normal boot as usual.

    Actually the Windows system is installed in C: Partition and the D: & E: just contains personal data also there's some important data which are contained inside C: Partition (how can i back it up ?) , Can you mention to me how can i backup data before proceeding with above mentioned solution by you (To avoid any trouble for you, do not cancel or interrupt CHKDSK, and back up important data) ? or it's better to mention in details the steps i should do in an ordered way and also take care of how not losing any data.

    Thanks in advance.
