Technician Questions

1. The operations, such as re-sizing or moving partitions, or disk conversion fail to execute after a reboot.

Before running Partition Master, it is recommended to close all other software including the anti-virus ones, so that the operations in Partition Master can be executed smoothly.

If the software still detects that pending disk/partitions are being used by other programs, it will pop up a windows asking to unlock or end the process. A reboot is not required if you choose to end all the process per request.

If you really can not get this done, please boot the computer from the WinPE bootable disk and execute the tasks. For how to create the bootable media, please check here. Any additional questions, feel free to contact techsupport@easeus.com.

2. What to do if the cloned disk cannot boot?

Make sure you have done the following instructions:
1. Clone the disk using Migrate OS function.
2. The cloned disk is connected by SATA instead of USB when you try to boot from it.
3. The cloned disk is set as the first boot order in BIOS.
If you have done all of these, but the disk still refuses to boot, please describe the issue in detail, take one photo of the failed boot and send it to techsupport@easeus.com. We will further analyze it and get back to you as soon as possible.

3. The computer gets stuck in an infinite loop after the operations are processed. How to solve this?

To solve this issue, please take the system disk out and connect it to another healthy computer as a slave. Access the partition containing operating system on that disk, then locate and delete the file "EPMBatch.ept" under Windows folder. After that, please connect the system disk back and boot from it.

And we want to remind you that file is hidden by default. So, please open 'My Computer', then choose 'Tools\Folder Options', Turn to 'View' page, check on 'Show hidden files and folders', uncheck 'Hide protected operating system files(Recommended)'. Then click "OK".

4. When cloning to a larger disk, how can I resize the partitions during the clone process?

You can edit the disk layout before processing the clone. Please check this screenshot.

5. How can I Interconvert MBR Disk and GPT Disk without any data loss?

It can be accomplished by a few clicks in Partition Master. Please check this link first.
If you can not find the option “convert to MBR”, please make sure that you have less than 4 primary partitions on this disk. If unfortunately there are more than 4, please only keep 3 of them, and convert other
from primary to logical.

If you want to convert the system disk from MBR to GPT, make sure the following points:

1. The computer motherboard supports EFI boot mode.
2. The disk has no more than 3 primary partitions.
3. The operating systems should be higher than Win 7, 64 bit.
If you want more instructions about the conversion, please contact techsupport@easeus.com with Disk Management screenshot attached.

6. What is the solution if the software fails to create WinPE emergency disk?

Make sure the following points before creating the bootable media:
1. If you use a USB flash drive, it should be MBR, with a newly formatted FAT 32 partition.
2. If the creation on CD fails, please try a USB drive instead.
3. If you still have trouble creating the WinPE bootable media, please send the following information to techsupport@easeus.com and we will send you the correct ISO image file.

What is the exact edition of your operating system? Windows 7, 10 or other?
Is it 32bit or 64bit system?
Is it LEGACY or EFI boot mode? You could check by this method:
a. Click the Search icon on Windows Taskbar and type in msinfo32, then press Enter.
b. System Information window will open where you can check your BIOS Mode.

7. I can not format the partition in Windows. Can this software help me?

I am afraid that the answer is negative. Our software can not help if Windows can not format.
