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




  • Linley Meslier

    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?

  • Kristopher Rhen

    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.

    Hi, I am experiencing this same issue. The dual-boot screen still shows up after all partitions are deleted. Any advice?

  • SignedAdam

    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.

    Hi guys here this method works 100% to remove cloudready efi i tried
    1.delete all partition above mentioned. will need bootable windows installation usb and boot the usb
    3.on windows installation click repair your computer at bottom left
    4.Go To Troubleshoot->Advance option->command prompt
    type following commands:
    -sel disk 0 (note 0 is your windows installed hard disk)
    -list par
    -sel par x(where x=partition no,please Note type=system,and size must be 99mb or 100mb or more of efi partition) This is efi partitton i mean
    -for eg:my efi partition is 1 so,
    -sel par 1 (your may be different partition number)
    -format fs=fat32 label=System
    -list par
    -select par 1
    -assign letter=b:
    -dir b:
    -mkdir b:\EFI
    -mkdir b:\EFI\Microsoft
    -cd /d b:\EFI\Microsoft
    -bootrec /fixboot
    -bcdboot c:\windows /l en-us /s b: /f ALL(note c:\ is directory where windows is installed)
    click continue and reboot


    note !!!!!!!!!!! dont do this step if the above method still dont work

    after doing   this  step  -bcdboot c:\windows /l en-us /s b: /f ALL

    bootrec /FixMbr

    bootrec /FixBoot

    OK so originally my partitions looked like that:

    Partition ### Type Size Offset
    ------------- ---------------- ------- -------
    Partition 1 System 512 MB 1024 KB
    Partition 2 Reserved 128 MB 513 MB
    Partition 3 Primary 237 GB 641 MB

    Now they look as follows:
    Partition ### Type Size Offset
    ------------- ---------------- ------- -------
    Partition 1 System 512 MB 1024 KB
    Partition 2 Reserved 128 MB 513 MB
    Partition 3 Primary 205 GB 641 MB
    Partition 4 Unknown 512 B 206 GB
    Partition 5 Unknown 512 B 206 GB
    Partition 6 Unknown 512 B 206 GB
    Partition 7 Unknown 512 B 206 GB
    Partition 8 Unknown 512 B 206 GB
    Partition 9 Unknown 512 B 206 GB
    Partition 10 Unknown 512 B 206 GB
    Partition 11 Unknown 512 B 206 GB
    Partition 12 Unknown 512 B 206 GB
    Partition 13 Unknown 512 B 206 GB
    Partition 14 Unknown 512 B 206 GB
    Partition 15 Unknown 512 B 206 GB
    Partition 26 Unknown 8 MB 206 GB
    Partition 21 Unknown 512 B 206 GB
    Partition 22 Unknown 512 B 206 GB
    Partition 24 Unknown 512 B 206 GB
    Partition 25 Unknown 512 B 206 GB
    Partition 17 Unknown 16 MB 206 GB
    Partition 19 Unknown 16 MB 206 GB
    Partition 23 Primary 1024 MB 206 GB
    Partition 27 System 16 MB 207 GB
    Partition 20 Unknown 3048 MB 207 GB
    Partition 18 Unknown 3048 MB 210 GB
    Partition 16 Primary 24 GB 213 GB

    Does this mean I can delete all partitions from 4-27?

  • Alex Bass

    No update on this? I have deleted all the partitions that were installed and yet I am still getting the boot screen to pick between CloudReady and Windows? :/

  • Philippe DEFERRE

    @bisaalz: Thank you, your method work though it needs some amendments:

    Hello EVERYONE trying to come back to single sign on on Windows, here is a method I used with success, based on the previous posts (Thanks to their authors, bisaalz, in particular, my contribution here is to complete because it was not working immediatly).

    The objective is to COMPLETLY come back to single boot option (Windows) and to remove the Cloudready/grub dual menu. Please do as following, I tested the method succesfully, but as usual, there is no warranty that it will fully work for you, so common sense is to read my shit completely before, evaluate if you can manage that on your own and backup you data FIRST.

    Last warning: touching the Boot is dangerous! And please note that my own Windows version is not in English so wording may differ slightly from my description.

    OK, if you want to go, here is the tutorial:

    1/ in Windows 10, using an Administrator account, open the Windows Explorer and right click on "This PC" and select "Manage". In the opening window, select Manage Disk at the bottom right 

    You should see your disk(s) partitions. Assuming your Windows is on the first disk, you will see a lot of partitions (Jeez, what for, Cloudready team?):

    The 3 first partitions are normally linked to MS Windows. As said before, they size 500MB (Windows tools?), 100MB (EFI = boot information, containing both Cloudready and Windows boot info) and some GB (your windows and data, size depending on your disk).

    Do not touch the 3 windows partitions and delete ALL the others (right click on each and click on Delete). After you delete the partitions next to the Windows one (the largest), there may be one resisting to your deletion attemp. It is a protected one, damn !

    When you cannot cleanup more, right click on the large Windows partition and try to expand it with the empty space you recovered after deletion of Cloudready small partitions.


    2/ OK, now click on the Windows > START > Reboot WHILE PRESSING SHIFT

    You will reboot in a "blue screen mode". Select Troubleshoot , then select Advanced options then select Command prompt

    You are now able to type commands to the system in the black cmd window.

    >>You are now going to erase and rebuild the Microsoft Windows EFI partition and boot menu. It is still time to step back! Just maintain your finger on the computer switch button for more than 4 seconds, and you are back to square one.

    OK, you have been warned ;-)

    3/ Type following commands in the exact order (modified from bisaalz) - note that each line is a command and comments are in ( ):

    diskpart (this will open the diskpart tool)

    sel disk 0 (note that 0 - ZERO- is your Windows installed hard disk) 

    list par  (this will list the partition of disk 0)

    sel par x

    (where x=partition with type=system and size =/- 100MB and not the one of 500MB, this is the EFI partition; mine was number 2, so I typed sel par 2).  BE CAREFUL AT THIS STEP !

    format fs=fat32 label="System" (Note this is in English, in French, it is label="Système", translate this into the language of your system)

    list par 

    select par x 

    assign letter=b: 

    exit (note that you will leave the Diskpart tool, but you are still in Command line black windows) 

     dir b (or b: note that prompt MUST be b> now)

    mkdir b:\EFI (it creates the folder) 

    mkdir b:\EFI\Microsoft  (it creates the folder)

    cd /d b:\EFI\Microsoft 

    bootrec /fixboot

    (THIS ONE AS NOT WORKED FOR ME: File not found, but don't worry)


    bcdboot c:\windows /l en-us /s b: /f ALL

    Note that c:\ is normally the directory where Windows is installed.


    c:\windows /l fr-fr /s b: /f ALL (see the fr-fr code ? this code refers to language-country short code, please adapt it to your Windows language and country).

    exit (you will now leave the black cmd window)

    4/ Click Continue and reboot your PC, you should now boot straight from Windows !

    Enjoy :-) hope this guide will help noobs like me !

    To CloudReady team: please note that I enjoyed your free system, but boot was slow to boot compared to my chromebook (Atom Z3850 vs Celeron 2950) and my Windows10 computer has an exotic wifi driver that is not in the latest Linux kernel for now (and not in Windows10 creator's update install files either), so I cannot use my laptop optimizely with your system, unfortunately.

    Create a recovery Drive
    By pressing
    Hit enter
    Press Next..........
    Wait for a while
    Select your Thumb drive at least 4GB
    After successful creation

    Boot into Recovery Drive (Your USB Drive)

    Choose your keyboard layout in my case It was US

    Use a device
    EFI USB device

    After a while it will restart your PC

    will perform a disk check let it happen
    Whalla done....

    Now you will not see cloudready select screen aka dual boot screen

    directly boot into windows 10

    All above steps were checked in Windows 10 could work in 8 (High possiblity) or 7 ...
    Give it a try

  • Adam Simon

    All of these options are great suggestions, but I'm having a bit of a different issue.  I no longer have the ability to boot from USB.  It's marked as enabled in BIOS/UEFI, but when I select it from the recovery menu I get a warning that tells me that it is not enabled.  Can't figure out how to fix this.  Advice?

  • SignedAdam

    @Adam Simon

    You need to select “other os” in the bios, or something similar, secure boot needs to be disabled as this only works with windows

  • Adam Simon

    Secure Boot is already disabled.  There is no option for "other OS."

  • SignedAdam

    @Adam Simon

    I’d try a cmos reset, then try again..
    If that doesn’t solve it, then look up the problem along with the motherboard manufacturer name online, as this post is about uninstalling cloudready and neverware support can’t help with hardware problems

  • Adam Simon

    This problem DEVELOPED in trying to uninstall cloudready (which I installed via USB).  It's not a hardware problem.

  • Adam Simon

    It's been in trying to UNINSTALL CLOUDREADY by following the advice in this thread, that I've discovered that I can no longer boot from USB, though my computer is still trying to boot into Cloudready, even though the partitions have been deleted.

  • SignedAdam

    Then it seems you have deleted a system Partition which your bios needs to do certain tasks, (a dependency) hp normally do this with laptops, you’ll need to go to the manufactures page, and reinstall this (dependency) or try updating your bios, if you can’t get back in to the original operating system (example windows) then you’ll need a recovery disk to restore the computer back to how it was, if you built the computer then again, update the bios as it’s sounds like a bios problem, so no one here can help you, only the manufacture of the motherboard/computer can,

    * Please don’t use caps lock, there’s no need for that

    * Warning any advice you have followed, sounds like you have, or are going to, comes at your own risk, the software you install or update, change or delete, is of your own choosing, so when problems happen, you are responsible, which is why installing cloudready is hidden away in the usb,

  • SignedAdam

    I did comment on this post about how to get rid of the selection menu, the thing you see at boot, you will need to find my walk-through, and follow it step-by-step,

    Instead of trying to get to the  recovery menu you could find command prompt in windows (open it in admin) and then carry on following my walk through 

  • ADogNamedGromet

    I have installed CloudReady on several machines and double booted them successfully with Linux Mint.

    First installing cloud ready first standalone from a USB drive as one normally would.  Then installing Linux mint from a DVD.  Linux mint is smart enough to set up the multi boot environment properly.

    and will even handle the partition adjustment nicely.  My goal was actually to run Windows in a VirtualBox machine and that also works well too although it is a little more involved and required a fair bit of reading.  I did do it and it works well.  I have run Windows 7 8  or 10 on Mint.   

    But I divided my drive into about 1/3 portions for each OS I wanted on it. 


    The only issue I seam to have is one machine doesn't like it very much and that is a HP Pavilion laptop dv7-2173ca. But it works on an Acer laptop I have as well.  It works on the HP but the CloudReady portion won't update to the most recent version.  I have read that this is an issue that the developers are working on.  

  • ADogNamedGromet

    As Linux mint is a very stable OS.  I also saw an article on here on running CloudReady on it as a Virtual box also.   see here

  • Meu computador só começa através de cloudready. Eu não posso entrar no Windows 10. Eu tentei arrancar o pendriver para consertá-lo e voltar para o Windows mais eu não consigo mais inicializar nem o pendriver nem o dvd

  • My computer starts only through cloudready. I can not get into Windows 10. I tried to boot the pendriver to fix it and go back to windows more I can no longer boot neither the pendriver nor the dvd

  • ADogNamedGromet

    OK I took off my dual boot scenario for a while from my HP DV7 laptop.

    I found that with Cloudready loaded on its own.  It still won't update past 66.4.25

    I think this is an issue with this specific laptop.  It was also doing this with dual boot with linux.

    Can anyone suggest why it is doing this in standalone?

    Thanks Rick  M

  • Forrest Smith

    Gromet -
    V66.4 is our latest stable version currently - that's why you don't see any updates :-D

    You can jump to v68.1 as of today on our dev release channel if you want, but be warned that instability is a reality on those releases.

    @Philippe DEFERRE


    Bootrec /fixboot  or

    bcdboot (Cannot copy files)

    worked, after the partition format.  Now my computer will not start at all.  HELP!
