Q: How can I know if partition can create recovery partition or not? (Free Space
Insufficient)
A: AOMEI OneKey will first check your system disk automatically to look for a partition which has
enough free space to create recovery partition. If there isn't any partitions meeting the needs, the
next step will be unavailable. In this case you may remove some useless files to free up enough free
space.
Q: If unallocated space is not large enough? (Unallocated space insufficient)
A: The selected unallocated space isn't large enough, so the program cannot use it for creating
Recovery Partition. There are two solutions to recommend to you: First, you use AOMEI Partition Assistant to resize the partition
or remove useless file to make an available unallocated space for creating Recovery Partition;
second, you can choose "Backup system to other location"
Q: Can I backup system to external hard drive?
A: If there is no enough space in computer partition except for external hard drive, only way of
backup you can choose is to backup system to other location. You can choose external hard disk as
the place where to store system image file. Of course, computer will also create a AOMEI OneKey
Recovery Partition, which is stored recovery environment, but it don't need much more space than
directly backup system to OneKey Recovery Partition.
Q: There are some partitions with adequate free space, why can't I choose it? (Inappropriate
Partition Layout)
A: AOMEI OneKey cannot create backup when there is a structure of "logical partition, primary
partition, logical partition" one after another, or even there will create such a structure when you
use AOMEI OneKey. In this case, please use AOMEI Partition
Assistant to covert the primary partition to logical and then retry or use AOMEI Backupper to do the backup.
Q: My computer partition has huge space, but why can't I create recovery partition? (Disks
Greater Than 2TB)
A: It may be that your system disk is MBR type (please check it for sure). MBR disk can’t be larger
than 2tb even if the disk capacity is larger than 2tb. So, if you want to make the extra disk space
available, just convert
system disk to GPT with AOMEI Partition Assistant, but make sure computer motherboard
supports UEFI boot mode. Then, OneKey Recovery can create recovery partition on system disk.
Q: Why is volume partition fail to be backed up?
A: If the system disk is a dynamic disk, AOMEI OneKey is unable to back it up, in this case, please
use AOMEI Backupper to do a system backup. It's
a-full-featured backup software. Or, use AOMEI Partition
Assistant to convert the dynamic to basic first, then, use OneKey to backup system
partition.
Q: There are three disks in my computer, why does only system disk show in the interface? (Only
create the recovery partition on a system disk)
A: There may be multiple hard drives on your computer, and you could hope to make a recovery
partition on secondary disks, but currently AOMEI OneKey only supports for create the recovery
partition on a system disk. If you choose "Backup system to other location", you can backup system
image to other disk, but Windows PE micro-system will be stored in system disk.
Q: My system disk's sector is not 512 byte, is it possible to backup system? (Non-Standard
Sector)
A: The sector size of your hard disk is not 512bytes per sector. AOMEI OneKey doesn't support this
kind of disks. It's called non-standard disk.
Q: How is recovery partition created? (Allocate Space from the Existing Partition)
A: AOMEI OneKey can only divide the existing partition (NTFS or FAT32 file system) for creating
Recovery Partition. There must have at least a NTFS or FAT32 partition, at the meantime, it has
enough free space, otherwise AOMEI OneKey cannot create Recovery Partition. But it is often the case
that you can allocate some free space from system partition for creating Recovery Partition.
Q: I unplug USB flash drive during AOMEI OneKey enters Windows PE, but I don't backup system,
why does software post error? (Disk or Partition Counts Changed)
A: AOMEI OneKey will automatically enter Windows PE mode to perform the backup. If the counts of
your disks or partitions changed during AOMEI OneKey enter Windows PE, the backup operation will
fail. So please keep the disk and partition counts as same as in Windows before it enter Windows PE
mode. If you encountered the issue, you can directly press the "A" key or use Windows boot menu item
to enter into AOMEI OneKey Windows PE mode to make a backup or restore when your computer startups.
Q: How to avoid Possible BSOD:
A: It is known that resizing system partition of Windows Server 2003/2008 may cause BSOD in a few
circumstances due to the special computer circumstance. So for Server 2003/2008 administrator, we
suggest you'd better choose a partition other than system partition for creating Recovery Partition
or use AOMEI Partition Assistant to shrink the system
partition, and then run AOMEI OneKey. Of course, The BSOD does not affect data and also does not
affect normal boot of the system.
Q: There are two ways in the interface of recovery, but why can only one option be
available?
A: There are two ways to back up, of course, there are also two ways to recover system. But, if you
just back up system in one way, for example, you just choose "Backup system to AOMEI OneKey Recovery
partition" this way to back up system, the only way to recover system is to use system image files
in AOMEI OneKey Recovery partition to restore system.
Q: Why I can't restore my system backup to MBR (Restoration of Different Disk Styles)
A: It is not supported to restore a system backup based on GPT to MBR disk or MBR to GPT disk.
Q: Can I use AOMEI OneKey Recovery to recover system backup created by AOMEI
Backupper?
A: AOMEI OneKey Recovery and AOMEI Backupper are products
designed by AOMEI Tech, though. Sometimes, in some condition, it will be not successful that recover
system image that created by AOMEI Backupper with AOMEI OneKey Recovery. Such as, image file of data
partition, image file of dynamic volume, image file in GPT disk.
Q: I stored system image in dynamic volume, why can't I recover system image?
A: You'd better not backup your system to such devices: Dynamic volume, Non-512Byte sector disk,
Network sharing, or the storage device that needs to load drivers and then can run normally. Because
process of backup and recovery will be running in the Windows PE model, and programs can't recognize
such devices.
Q: Can I restore my system image to the partition that is right to recovery partition?
A: If you use AOMEI OneKey to restore your system to the place on the right side of Recovery
Partition, after you reboot, the System Backup feature will be no longer available. The reason is
AOMEI OneKey will delete the previous Recovery Partition at the next time when you are trying to
renew the Recovery Partition, that may cause the system cannot boot anymore, so for safety, you are
forbidden to renew recovery partition. If you want relive this limitation, please use AOMEI Partition Assistant or Windows Disk
Management to delete the Recovery Partition.
Q: After system image is recovered to other disk, the setting in AOMEI OneKey can't be working?
(why has the prompting words "press A to enter AOMEI OneKey Recovery" gone)
A: After system image is recovered to other disk, instead of the disk where former system partition
is, and then boot computer from the destination disk, the setting in AOMEI OneKey Recovery will not
work. Because setting options have been set by program before backup, but it is aiming to the disk
where former system is. System booting from Destination disk can read the setting option that was
set before, though, the setting option can't work. If you want use starting setting, you have to
back up current system with AOMEI OneKey Recovery.
