Best Alternative - EaseUS Partition Master

Although BIOS doesn't support disk partitioning, you can still create partitions on your SSD before without booting the Windows system - using Windows bootable media. Since Windows doesn't offer any built-in tool to create bootable media, we recommend EaseUS Partition Master in this case. It is an efficient partition manager with corresponding functionality for creating bootable media and partitioning hard drives.

With its "Bootable Media" feature, you can create a Windows bootable media effortlessly. Then, you can partition your SSDn smoothly with its "Create" feature. Now, you can install the EaseUS Partition Master and follow the step-by-step instructions below to find out how to partition your SSD from BIOS.

1. Create EaseUS Bootable Media

Step 1. To create a bootable disk of EaseUS Partition Master, you should prepare a storage media, like a USB drive, flash drive or a CD/DVD disc. Then, correctly connect the drive to your computer.

Step 2. Launch EaseUS Partition Master, and find the "Bootable Media" feature on the left. Click on it.

Step 3. You can choose the USB or CD/DVD when the drive is available. However, if you do not have a storage device at hand, you can also save the ISO file to a local drive, and later burn it to a storage media. Once made the option, click the "Create" button to begin.

• Check the Warning message and click "Yes".

Step 4. When the process finishes, you'll see a pop up window, asking if you want to restart computer from the bootable USB.

• Reboot Now: it means you want to restart the current PC and enter EaseUS Bootable Media to manage your disk partitions without OS.
• Done: it means you don't want to restart the current PC but to use the bootable USB on a new PC.

Note: To use the bootable disk on a new PC, you need to resart the target computer and press F2/F8/Del key to enter BIOS, and set the USB bootable disk as the first boot disk.

Wait patitiently and your computer will automatically boot up from the USB bootable media and enter EaseUS WinPE desktop.

2. Partition SSD from BIOS

Step 1. Launch EaseUS Partition Master to check for free space at the Partition Manager section.

• If your hard drive has unallocated space, jump to Step 3 to create partition.
• If the hard drive has no unallocated space, continue with Step 2.

Step 2. Shrink a disk partition to create unallocated space.

Right-click on the target drive partition with a lot free space and select "Resize/Move".

Drag either end of the partition rightwards or leftwards to shrink the partition size so as to get ample unallocated space. You can visually know how much space you've decreased in the "Partition size" area. Click "OK".

Click "Execute xx Task" and then "Apply" to save all the changes.

Go back to Partition Manager, there should be unallocated space appearing on the same disk and you can continue with the next step to create new partition on your hard drive.

Step 3. Create a new partition with unallocated space on the target hard drive.

 Right-click on the unallocated space and choose "Create".

Customize the partition size, partition drive letter, partition label, file system (NTFS, FAT32, EXT2/3/4, exFAT) and more in the Advanced Settings. Click "OK".

Finally, click "Execute * Task" and "Apply" to complete creating partition with the unallocated space on your disk. Repeat the steps to partition a hard drive and get many more partitions.
