[Solved] We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files.

Yesterday I try to install Windows 8 RTM on my laptop as a second OS (Dual boot with Windows 7), so I chose custom install. After selecting the drive I would like to use and clicking next, I receive the following error:

We couldn't create a new partition or locate an existing one. For more information, see the Setup log files.

When I encountered this error message I have three external HDD, a SD Card and one USB Thumb Drive / Flash Drive connected to my laptop. So I remove SD card and disconnect all external HDD from USB port, only one thumb drive connected to USB port because it contains the Windows 8 Setup files. Then I ran the setup again, finally I can install Windows 8* seamlessly. Hope this helps!

            Boot from your USB flash drive as usual,
            Choose “Repair” then go to the advanced tools and start the
            command line.

            Start DISKPART

            Type LIST DISK and identify your HDD disk number (from 0 to n disks).

            Type SELECT DISK where is your HDD disk number.

            Type LIST PARTITION

            Type SELECT PARTITION where is your partition number of the last drive (Drive 0 Unallocated Space 20 Gb)

            Type CREATE PARTITION PRIMARY

            Type ACTIVE

            Type FORMAT FS=NTFS QUICK

            Type ASSIGN

            Type EXIT twice (one to get out of DiskPart, the other to exit the command line tool)

            then,,, try to install Windows 8 again….

            do you have windows XP on your netbook?
            download this:
            http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html
            and play with your HDD/partition.. if the disk is “dynamic” change it to “basic” etc…

          • angelcyber942

            i have not windows xp inside my netbook , only backtrack i have , before i was try to create partition with gparten on my backtrack and change them to ntfs ,

            so i must install windows xp on my usb and then try to create partition using easus ?

            or how ?

          • picohelp

            well..
            maybe I was wrong in the diskpart command sequence …
            but, the only thing you should do is make the partition as “primary” and “active” and then format it as NTFS.
            and we only can create partition primary on empty disk.. so please backup all you data! because “clean” command will wipe all your partitions and files…. and you have to re-install linux backtrack

            do the following:
            boot from USB flash drive > try to install Windows 8 > when the setup fails to find the partition, close the window (click X on top right corner)
            you should be brought back at the initial setup screen > Choose “Repair” then go to the advanced tools and start the command line.

            from here.. try to play with diskpart again:

            Start DISKPART.

            Type LIST DISK and identify your HDD disk number (from 0 to n disks).

            Type SELECT DISK where is your HDD disk number.

            Type CLEAN (be careful!, please backup your data first)

            Type CREATE PARTITION PRIMARY

            Type ACTIVE

            Type FORMAT FS=NTFS QUICK

            Type ASSIGN

            Type EXIT twice…

            Then try to install Windows 8 again…
            on this step:
            http://www.picohelp.com/wp-content/uploads/2012/06/Step151.jpg
            you can create another partition for your linux backtrack..

          • angelcyber942

            hmmt.. i think i must do these step to dual boot win 8 & backtrack , eventhough i will waste my time to install again and setting , but i think these step will work. so , i will take a time to do these but not right now , i will give u if i am success to dual boot. and thank in advance for your help friend 😀

          • IT WORKED, thanks man it finally let me through and its installing like a breeze

          • angelcyber942

            i am success right now , thanks for your help friend 😀

          • Anugrah

            i did this also but i am still not able to install windows 8.
            I am trying to install windows 8 on a HP Ultrabook which has a 32 GB SSD drive.

            may be the SSD drive is behaving like an external SD Card.

            Can you suggest how can i temporarily disable my SSD ?

            Thanks in advance
            Anugrah atreya

          • Ray

            Thanks! For others reading, this “ALMOST” helped… Nothing helped until I did this (which did not originally work) and restarted (which booted from USB)… Clicked on the “ONE” drive listing remaining and had to click “delete” to get unallocated space per http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html then finally the “Next” button was no longer greyed out and Windows 10 started installing! Whew! Yay…. It seems that my biggest problem was I had all of the partitions from the HP Pav build… your instructions removed them… then “delete” gave me unallocated… I am assuming if I just did a delete on all partitions during the installation then I would have gotten the same and it would have worked too. Thanks!

          • ArrowAssault

            apparently, it’s critical that in the BIOS the intended disk is listed in boot order as the first boot device, or you get the error:

            “We couldn’t create a new partition or locate an existing one”

            nothing you do will make a difference if it’s not set as first boot device. Once I scooted DVD to second boot device and drive c: as boot device 0, installer’s complaints magically vanished and install is proceeding now. Could have saved hours if I realized this sooner.

          • Nick Hanson

            Thank you SO MUCH, it was as simple as making the target drive first in the boot menu 🙂 Good work ArrowAssault

          • ArrowAssault

            Thanks!

          • vk

            I did this but still had problem. Then removed the other drives, removed the SSD and connected it back to another port. Then tried and it worked. before this windows was saying the bios was not support thing SATA and doesn’t have controller enabled when I double click the hard drive partition in the setup above.

  • thanks, it works for me. 🙂

  • M A Bhatti

    still not able to create partition please help picohelp

  • Colin Milker

    100% right, thank you pulled USB with SD card in it out & worked right away!

  • Macklin

    its good.. command success full….

    Start DISKPART

    Type LIST DISK and identify your HDD disk number (from 0 to n disks).

    Type SELECT DISK where is your HDD disk number.

    Type LIST PARTITION

    Type SELECT PARTITION where is your partition number of the last drive (Drive 0 Unallocated Space 20 Gb)

    Type CREATE PARTITION PRIMARY

    Type ACTIVE

    Type FORMAT FS=NTFS QUICK

    Type ASSIGN

    Type EXIT twice (one to get out of DiskPart, the other to exit the command line tool)

    then,,, try to install Windows 8 again….

      After entering “active”, it gave error:
      “Virtual Disk Service error: The specified partition type is not valid for this operation.”

      I’m trying to install Windows 10 Preview on a logical partition.

    • Bruney Castañeda

      OMG! It’s working thank you!!

    • Did not work.

    • Shawn Bray

      it worked for me on win 10 pre and i ignored the not enough space warning

    • Muhammad Shoaib

      I updated to win 10 from win 7 recently. My Dell latitude 6410 was working fine then suddenly display went off. A friend suggested to install win 10 from start. So when I was installing win 10 I got this error. I tried your disk part method but still the same error. Please guide me what to do

    • Erty Ytre

      nice one mate! cheers
      note: “active” gives an error on a non-MBR volume, just ignore it and move along with the other commands. then after exit make sure to refresh the list of drives, select the partition and go.
      edit: on windows 10 anyways. also if you already have a non-working partition from the installer make sure you delete it before doing this – only works with free space.

      • Chrome Burns

        thanks! this fixed my issue:

        “on windows 10 anyways. also if you already have a non-working partition from the installer make sure you delete it before doing this – only works with free space.”

    • Rann Xeroxx

      Had the error “virtual disk service error” as well and just ignored it and this fix also worked for me. Thanks Macklin!

    • Mathias

      I still get the same warning:

    • Joshua Barajas

      Hey do you know if your using a 3.0 usb into a 2.0 slot? thx

    • Dusty

      If using a large USB drive, 32 gb or more, they have a default Ex fat32 format that caused Windows install to stop at this point.

  • AM

    I have the same problem, and I tray this solution but the problem has not be solved! Help

  • ndubinkin

    Thanx, man!

  • sri

    i have a dual boot, c: has xp and d i deleted and created partition to install windows 7, same pbm……

  • Say What?

    All you have to do is go into your BIOS and change the boot order to the drive you are trying to install Windows to. Make sure it is first in the boot order. Viola, no more partition error.

    • Samizdata

      Chiming in to say this was the problem and the fix DOES work. (Desktop with three internal HDs and two optical drives.) So, Say What?, you rock AND you made my night! Cheers, good sir/madam, cheers, I say.

  • francis

    you’re the man!!!! i got head aches of this problem.. ilove you bro!!!! 🙂 thnx alot really helps!!! 🙂

  • BFBunny

    Change the boot order so that the drive you want to install to is listed as the first one. This worked for me.

    • Server Install requested B110i driver. loaded driver with USB stick and left stick in USB Port for convenience. Spent next several hours beating my head against the wall until I read BFBunny’s solution. Changed boot order and placed USB Stick after the Install drive. Worked perfectly.

    • Stephen Ehlert

      Thanks so much. I tried everything else over and over again until I saw your comment, and this solution finally worked!

    • Max

      THAT did it for me.

    • JoshuaSchlag

      Ding ding ding! This did the trick for me too. Thanks!!!

  • Omegaman5

    LOL OMG!

    Dude you are the Man !
    2 years later and you”re the only one I found that gave the instructions to get up and running.

    4 days (and nights) later and I’m back in the Game !

    Thanks Bro !

  • James Durr

    I left my other drives plugged in, but this only worked after moving the destination drive for the install to the first boot device within my BIOS.

  • Daniel

    Did all actions recomended where the only one that worked for me was changing the boot order so that the drive you want to install to is listed as the first one, so thank you @BFBunny

  • Apteryx

    The solution is so simple you will kill yourself biggrin.gif

    Just before you reach the custom install screen where the process falls over, remove the USB stick, wait a few seconds, then re-insert it wink.gif

    • JAG

      You are absoulutely right! Just unplugged the USB stick 5 secs and it works! Thanks!

      • Apteryx

        I just had the same problem for the second time and this time this technic didn’t work, I unplugged all useless disks and it worked.
        Try that if you can’t manage to success with this.

    • EAt

      I was the same problem with Windows 10 and your solution works. Thank you!

      • Gerbil

        I couldn’t tell when the “right” time was so this is what I had to do (installing Windows 10 from USB stick):

        1. Get to the place where the error occurs.

        2. unplug the USB stick
        3. Click “Refresh” – you get some different error about why it can’t install to this partition
        4. re-plug in the USB stick
        4.5. It’s POSSIBLE that I then clicked “Refresh” again
        5. Highlight the drive I want to install to
        6. Next and it works.

        • Jack Cook

          That worked perfectly. yes after the re plug the USB stick, click refresh and and next.

        • Sana Qureshi

          oh my GOODNESS! Thanks bunches!

        • YES!!!!

          Step 4.5 the second refresh. Yes you did need to do another refresh after getting the different error message.

          What a dumb bug. Spent hours on this shite.

      • John Henderson

        That worked for me!

    • JS

      This worked for me! Thanks

    • KLF

      THANKS!!!!
      I don’t know why, but this worked fine
      (Esto funciono excelence, porque? ni idea)

  • RW

    Thanks so much for this. Works great for windows 10 installation via USB key. The trick is indeed to reorder your boot list so your SSD is boot #1 drive. After that I clicked new drive and then Next. Bingo. PS: Removing the USB key did nothing for me as well.

  • Ashiq Ullah Mangal

    Just change your usb device from 3 to the old one 2. It will solve your problem 100%.

  • J-B Lai

    I have found a fairly simple solution. (This if for people who are installing via USB)

    1. Go into your bios and set the HDD that you want to install as the very first boot device. Save and restart.

    2. Manually access your boot loader when bios starts. From here select your USB to boot with.

    3. Proceed normally with the install.

    It seems that the partition manager in the windows installation gets confused when when it detects a USB that has a higher boot priority then the HDD you’re installing on. It thinks the USB is the system partition. By setting the HDD to the first booting device, it no longer looks at the USB as a boot device.

    This would also explain why the remove USB key while creating the partitions work. By removing the USB, it no longer sees it and so it skips to the next bootable device to look for the windows system partition. When it doesn’t find one, it will now device to create it on its own.

    Hope this helps some of you. It took a few hours of sleep out of mine.

    • Karl E

      Thank you so much! This happened to me when doing a clean install of Windows 10 from a USB to an SSD. The boot priority was the solution.

      • J-B Lai

        You’re welcome =) I was in the same situation as you a few days ago… took me 2 whole days of reading and trying things out. So wanted to share this with everyone.

        • John

          How do I access manually boot loader ?
          If i make my SSD Boot option 1.. it is not starting with message “Operating System not found”
          and when I start with my USB(boot able windows 10) it gives me error “We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files.” than I used Diskpart etc… I have to reboot laptop and same problem again. Please help

    • Mk

      Thank you very much. this worked for me

  • Nikolai Donchev

    Hi, that’s not the first time I encounter that problem and it’s very annoying. Here are two solutions that have worked for me (I have tried all from the comments with no luck).

    SOLUTION 1:
    Install Windows from Optical Drive.

    SOLUTION 2:
    Unplug all USB devices except the Boot USB Drive from the computer and restart. In my case I unplugged an USB Keyboard and an USB Mouse. It worked like a charm 🙂

    Good Luck 🙂

  • Damar Adi

    Don’t forget to unplug the usb mouse as well, guys.. It works for me!

  • Duffy

    After a lobg tries to solve this problem on my Dell C1100 server with PERC H700, i’ve found one more solution: remove all virtual exept one(where you ppan to install win) from raid controller , and make imaket first in boot priority.

  • Derek Nason

    Dude! Saved me a headache right there! I unplugged the usb mouse and backup drive, able to install now. Thanks!!

    Edit: Had the error on a Fresh install of windows 10 Pro x64, not windows 8.

  • Do not use 3.0 usb as your installation usb. Go for 2.0 usb ones fixes all your problems.

  • Damien

    I found a solution this happend because windows need some little space extra something like 31mb . But the shit it should be a partition 😀 windows says its windows capability disk something like that .(correct me if im wrong )if u can delete all partions and create couple of new the issue will go to the hell but if u have usefull luggage inside try installing win xp because it will create that small shit at the disk selection menu .hope u can understand

  • Roman Avery

    Thank you so much! I had this problem on a server where I was trying to install Windows 10. I fixed it by unplugging every SATA cable except for the hard drive I was installing on.

  • Npanga

    thank you I have solved this problem by the help of you while installing windows 10.

  • Marvin Ageling
  • aj

    Got into the bios and loaded the optimized defaults ran installation again and voila

  • well the problem is that your disk is possible formated to MBR. You must make it to GPT. GPT is newer boot Tech. To resolve the problem formate the needed partion to the GPT format. Then you are done and can install and do stuff.

    Following current tip

    Open the diskpart tool:

    diskpart
    list disk
    Select the drive, and reformat it:
    select disk
    clean
    convert gpt
    exit

  • Kurt Hitchen

    Thank you so much! This worked for me with a Windows 10 installation. Your saved my life (well, at least, my computer)!

  • Chris Newman

    Old topic but I had to move the USB bootable drive I was installing from off the expansion port and place it in the onboard USB ports.

  • Douglas Jarden

    Same issue with S2012R2. What I had to do, was copy the B120 drivers (HPSA2.inf) from cp027782.exe on to the same usb stick I had the S2012R2 install files on. it didn’t like having an additional usb stick containing the drivers. I didn’t need to change the disk order in bios – though that may have also resolved it. my guess is that this would work fine if I used the ilo instead of USB sticks.

  • Siddhant Srivastav

    if i use this method :

    Start DISKPART

    Type LIST DISK and identify your HDD disk number (from 0 to n disks).

    Type SELECT DISK where is your HDD disk number.

    Type LIST PARTITION

    Type SELECT PARTITION where is your partition number of the last drive (Drive 0 Unallocated Space 20 Gb)

    Type CREATE PARTITION PRIMARY

    Type ACTIVE

    Type FORMAT FS=NTFS QUICK

    Type ASSIGN

    Type EXIT twice (one to get out of DiskPart, the other to exit the command line tool)

    then,,, try to install Windows 8 again….

    Will i lose data on the other partition?

  • Jj

    Just select the drive and click remove and then you will get a new option called (new) click it and then you’re ready to install

    You’re welcome

  • ArmoredWolf

    My laptop kept showing the error about locating an existing partition, I tried every single solution in the comments, but what finally worked was simply select the disk and click delete to set the space as unallocated. No partitions or anything. And then it suddenly let me install windows 10 normally 🙂

  • Nilesh Sutar

    if there is system reserved space available then extend the partition with unallocated space it 100% works
