    What should I do if I am unable to boot my Windows PC after changing the drive letter in “Disk Management”?

    I just went into the Disk Management and changed the drive letter for one of the partition but mistakenly a new active partition was created and right after that I am not able to boot my PC. Can you tell me how to fix it and make my PC boot up properly?

    Hi,
    I do not think that your machine is not booting due to a failure in disk management. Just changing one letter will not shut your entire system down. If it is the C Drive name that you have changed then also this kind of a booting problem should not occur. What really happened with your machine is that it is affected by virus and now the system has totally crashed and is unable to boot. If you are not able to open your PC at all, then I guess, you will not be able to switch open the machine via a safe mode.
    So in your case best option is to format your operating system totally and re-install it again. After you do it, keep an antivirus in your machine for cleaning your system and alerting you from any risks.

    Hi,

    Really a sorry state for you, insted of management, the system now is in disarray.

    Actually using the disk management utility you have changed the identity of the drive. The c:\ is the most vital identity that all computers have.

    C:\ is the drive from where the computer boots. Booting is the important most task the computer performs on its own.Without booting a computer will remain dumb and will never be able to interact with you, So booting is vital.
    Now, all the pre booting and booting helper files , bootables , remain in c:\ namely IO.SYS, MSDOS.SYS and COMMAND.COM and afterwards Windows BOOT.INI etc.
    When the bootloader searches for those files in c:\ it doesnt find them as the c:\ has changed into something else. What to do?
    It will remain DUMB for sure.
    Do a low level format and install windows afresh to get back the possession of your computer.
    Thanks.
