Can’t Create New Partitions Windows 8

Necessity of Creating New Partitions in Windows 8

 
Creating partitions in Windows 8 helps us to manage our files and documents better. Usually, a hard disk is divided into at least two partitions, one for system storage and one for data storage. Of course, three or four partitions will be better; for we can classify the files and documents more distinctly.
 
Besides, sometimes we need to install dual-system out of some reasons. Thus, we have to create another partition for system installation. However, we may get into trouble that we can’t create new partitions in Windows 8. This post summarizes the bad situations and corresponding solutions for your reference.
 

Situation One: Can’t Create New Partitions when Installing Windows 8

 
The first bad situation is that when you are trying to install Windows 8, you receive a prompt saying “We couldn’t create a new partition or locate an existing one. For more information, see the Setup Log Files.” In this case, what will you do?

 
I am trying to install Windows 8 from USB on to an empty 1 TB Seagate Barracuda HD. Whenever I attempt to install, I get the following error message stating “We couldn’t create a new partition or locate an existing one. ”
 
I have tried numerous solutions posted online, but with no success.

Solution One:
Changed the USB 3.0 flash drive to a USB 2.0 stick.
 

Solution Two:
Change the order of the hard disks in BIOS for boot priority. Moved the hard disk where you are installing system to the top of the list. And then install Windows 8 by using installation CD.
 

Solution Three:
Run Setup. Once the Setup fails to find the partition, just close the setup window and back to the initial setup screen. Choose “Repair” and then go to Advanced Tools and start the command line.
Start DISKPART.
Type LIST DISK and identify your disk number (from 0 to n disks).
Type SELECT DISK where is your disk number.
Type CLEAN.
Type CREATE PARTITION PRIMARY.
Type ACTIVE.
Type FORMAT FS=NTFS QUICK.
Type ASSIGN.
Type EXIT.
 

Solution Four:
Unplugging all other hard drives and every USB device except the flash drive that you are booting Windows 8 from. Then doing the command prompt operations above.
 

Situation Two: Can’t Create New Partitions after Installing Windows 8

 
Another bad situation is that you cannot create new partitions after you have installed Windows 8. Here are the possible reasons:
 

1. No unallocated space or free space
This condition can be easily resolved by shrinking a partition to create a new one.
 

2. No extra partition entries in partition table
This happens on MBR disks. If there are already four primary partitions in a MBR disk, you cannot create a new one unless you convert the basic disk to a dynamic disk. Or you should convert MBR disk to GPT disk if it is possible.

3. Can’t delete Recovery Partition to create new partitions
 

I’ve created a Factory Default Backup with a USB drive with Acer Recovery Management. I see this message which tells me I can delete the Recovery Partition to free up disk space after I’ve created the backup but it never gives me the option to do so. I appreciate any help. Thanks.

Recovery Partition is another resource users want to make use of to create new partitions. The question listed above is typical. When it comes to partition management, users often turn to Disk Management for help. Unluckily, Windows 8 Disk Management will disappoint you this time. Only a “Help” option is available.

Then how to delete Recovery Partition to create new partitions? Normally, two ways are feasible.
 

Try command line option:
Run “cmd.exe” as administrator, and then type “DISKPART” inside the cmd window. Press Enter key to type the following command in order:
Type LIST DISK (check the disk number).
Type SELECT DISK X (x is the ID of your disk to erase).
Type LIST VOLUME (check the Recovery Partition volume number).
Type SELECT VOLUME X (x is the ID of your Recovery Partition to delete).
Type DELETE VOLUME (or type “DELETE VOLUME OVERRIDE” if your get error message).
Type EXIT.
Reboot your pc, and thenyour Recovery Partition will be erased completely. Now you can create a new volume by using Windows 8 Disk Management.
 

Try bootable partition magic:
A safer way is to try using partition magic: MiniTool Partition Wizard Free. With this useful tool, you can easily delete the Recovery Partition and then create new partitions in Windows 8 or 8.1, even if you are a computer newbie.
 

First of all, you need to download the iso file and burn it to a USB flash drive or CD/DVD Disc.
 
Reference: How to Build Free Bootable Partition Manager with Pwfree91.iso?
 

Then, connect the USB flash drive or CD/DVD Disc to your computer and set your computer to boot from this bootable media in BIOS.

Soon you will see the welcome page of MiniTool Partition Wizard and get in its main interface.

Now you can take actions to delete the Recovery Partition. Right click the Recovery Partition, and select “Delete“; again right click the partition, and select “Create“. Finally, Press “Apply” to execute all operations.
 

Tips: If there are already four primary partitions on your MBR disk, set two partitions (apart from the system partition) as logical before you delete the Recovery Partition. Or you can convert MBR disk to GPT disk in advance if it is possible.
 

Note: If you only want to release free space from the Recovery Partition instead of deleting it, you can refer to Move/Resize Partition, and then create new partitions in Windows 8.
 

Further Reading: Can I Delete System Reserved Partition to Create/Expand Partition?

 

Apart from Recovery Partition, you may have also noticed that there is a System Reserved Partition in your disk after you have installed Windows 8 on a new drive. And the question is: can I delete System Reserved Partition to create a new partition in Windows 8?
system-reserved-partition
 

The answer is: BETTER NOT, because System Reserved Partition is created by Windows to store system boot files. Your computer boots from the System Reserved Partition first, and then boots Windows from your system drive. But if you have to, the ideal solution is to prevent it from being created at the beginning. You need to create partitions before you install Windows 8.

 

But if you don’t want to reinstall Windows 8, you will have to take a risk to move the boot files from the System Reserved Partition to the main Windows system partition. This operation involves a lot of changes, like modifying the registry, copying files between drives, marking the main system drive active, etc, and is harder than you have imagined. What’s worse, it’s not officially supported by Microsoft. So we don’t recommend it.
 

Why take such a big risk of messing up your operating system only to get a tiny bit of free space less than 100 MB or 350 MB? You will make the wise decision.
