How to Solve the Error "We Couldn’t Create a New Partition"?
Share this:

When you trying to install Windows 8 or Windows 8.1, you may come across the following error message:

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

What cause the error? According to survey from major computer forum. There may be several reasons.

  • Install Windows 8 on computer as a second OS (Dual boot with Windows 7 or Windows XP).
  • Install Windows 8.1 for updating from Windows 8 or ran Windows 8 upgrade assistant.
  • Had Ubuntu installed PC before install Windows 8.

Note: whether you had formatted the hard drive you want to install Windows 8 on has noting to do with the error.

Windows 8 can only accept at most 4 primary drives. If you already have more than 4, the setup process will give you the same error information. You can get rid of the message by disconnecting the additional hard drives while installing Windows.

If you have SD Card installed on the computer, Windows 8 will usually fail to recognize it during installation and will give the same error of not being able to create a new partition or locate an existing one. The work around of this problem is to temporarily disconnect the SD Card and install Windows 8 on the HDD. When the installation is complete, you can insert the SD Card again.

  1. Check if you have an SD Card in the system. If you do, you remove it and run setup again.
  2. Once the setup fails to find the partition, just close the setup window (the top-right-hand side red X does the job).

From that point, you should be brought back at the initial setup screen. Choose "Repair" then go to the advanced tools and start the command line.

Start DISKPART.

TypeLIST DISK and identify your SSD disk number (from 0 to n disks).

Type SELECT DISK whatever disk number you have.

Type CLEAN.

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).

Perform the above for any other HDDs present, but don’t make any other drive active at the same time of course. Then reboot and start in the installation over again.

Notice that “Disk” and “partition” are at the forefront of the above content. Diskpart.exe is the most important tool. Let us have a look at what it is.
