How can I Remove the CloudReady Half of my Dualboot Setup?


You're looking to uninstall CloudReady-- it either wasn't for you or your device/model didn't work when you dualbooted! This guide will tell you how to wipe CloudReady from your drive: crucially, you'll have to do this from within Windows using the Disk Management program and not the file explorer. 

Affected Versions:

All versions


Affected Editions:

Education, Enterprise, and Free



  1. Open your Disk Management tool. Ways vary between versions of Windows, but the most accessible way is to use your search functionality via the start menu (or equivalent) and search for "Disk Management".
  2. Right-click and delete each partition above number 16: these are all associated with CloudReady. 
  3. Below partition 16 will be your original Windows partitions, along with several smaller partitions called stubs.  Right-click and delete these stubs with care. During setup, CloudReady creates a variable number of "stubs" to reach 16 as there can be a different number of initial Windows partitions. These stubs will be of equal size and comparatively very small (less than 1MB-- usually 512bytes).
  4. Expand the main Windows partition to fill the now-empty space.

    That did not work. I deleted the partitions and I still get the dual boot choice screen after I reboot my laptop. What am I doing wrong?

    What are these stubs and can they be removed post-Install? Are they just cluttering up the partition table? Do they serve a purpose for the running CloudReady OS?

    Dear Neverware,

    I cannot get rid of CloudReady's EFI.
    After having erased all disk partitions, I am still being prompted to choose CloudReady or Windows.

    Please help me resolve the issue.

    This might work

    Download easyuefi, click free download, then delete the CloudReady efi entry and/or

    (tested up in-till the command) so do this at your own risk

    reboot in to windows 10 recovery by holding down shift while choosing restart, keep holding it till you see options,

    troubleshoot - advanced options - start-up settings - restart

    pick windows in the CloudReady grub bootloader, you should now be seeing a blue screen,

    press f10 - press 1 - troubleshoot - advanced options - command prompt

    now enter "bootrec /FixMbr" this should remove the CloudReady grub bootloader, 

    if not try :

    bootrec /FixBoot
    bootrec /RebuildBcd

    this is all at your own risk, me and the CloudReady team are sorry to see you go

    good luck

    The only way that I found to solve it is to install ubuntu in dualboot. When you install Ubuntu in dualboot the mbr of Windows is solved and after you can to delete ubuntu and choose the first entry at "windows boot" in Bios.
