Lazesoft Recovery Suite V4.1 has been Released

Lazesoft Recovery Suite, version 4.1 has been released! It has many new features, including the ability to install Windows 10 on your external USB disk. In addition, a Lazesoft BCD Doctor option and a Lazesoft boot disk start menu have been added.


As you know, Windows 10 will be released this month. If you are still deciding whether to upgrade to the new version, Lazesoft can help. There are so many conflicting suggestions and articles about Windows 10, and, maybe you are one of the millions confused by the information overload.


We think that the best suggestion for you is safely and temporarily trying Windows 10 on a USB disk before you upgrade it on your internal hard disk. To help you out, our new version of the Lazesoft Recovery Suite has added a helpful new function, ‘Install Windows 8/8.1/10 on USB disk’, which can help you to decide if you really want to adopt the new Windows version.


“After installing Windows 10 on USB disk, you will have a portable and full functioning Windows 10 on your USB hard disk without any changes to your data, applications or settings for your internal hard disk” said by Rex Deamon, the Product Manager for the new and improved Lazesoft Recovery Suite.


The Lazesoft Team is always trying to provide solutions for protecting and repairing user’s computers’ data and boot system. The newest function in Lazesoft Recovery Suite v4.1, is the Lazesoft BCD Doctor, for managing and repairing the BCD store/file, an important and complex component of the Windows boot manager. The BCD file is vital for Windows Vista, 7, 8, 8.1 and 10 boot processes. Problems with the BCD file can cause Windows to become unbootable. Lazesoft BCD Doctor, in Lazesoft Recovery Suite, provides the Fix/Rebuild function capable of fixing any BCD file errors in one click, even if Windows does not boot normally or has crashed. Lazesoft BCD Doctor has many easy-to-use and helpful functions, such as, adding or deleting the BCD Menu, or editing the BCD Menu.


Lazesoft Recovery Suite is the premier all-in-one recovery package, offering many useful tools. These useful functions are found in different modules of Lazesoft Recovery Suite, including Data Recovery, Password Recovery as well as Disk Image & Clone. To help users to quickly access the useful tools on the Lazesoft boot disk, a Start Menu has been added to the v4.1 version. Using the Start Menu on the Lazesoft boot disk, users can quickly launch handy tools, such as File Manager, Registry Editor and Network Setting.

To decrease the backup drive image file size and improve backup speed, the new version of Lazesoft Recovery Suite excludes/does not process the pagefile.sys, hiberfil.sys or swapfile.sys files when backing up a system disk/volume to a file.


The new version v4.1 Lazesoft Recovery Suite supports recovering/finding the Windows 8/8.1 OEM product key from both the Windows registry files and BIOS. Users can recover or extract the Windows 8/8.1 OEM product key from BIOS, even if the Windows partition or disk is formatted or wiped.

Install Windows 8/8.1/10 on USB disk

Upgrade to Windows 10, or no?

Try Windows 10 on your USB hard disk using the method in the video without worrying about the current Windows system installed on the internal hard disk.
Microsoft has finally announced “Windows 10 Will Be Released July 29th 2015 as a free upgrade for users of Windows 7 or later”. You are probably eager to upgrade to Windows 10, but may be worried about upgrading, and overwriting your current Windows version.
Using the function, “Install Windows 7/8/10 on USB disk”, in “Lazesoft Recovery Suite”, you can install Windows 10 on a USB hard disk without affecting your current computer set up. With our new program version, you do not need to worry about any possible effects on your current Windows installation or the data on your internal hard disk.
This video shows how to try Windows 10 safely using new version of “Lazesoft Recovery Suite”.
Windows versions are becoming more and more portable. A true, portable, Windows version must support execution from a USB hard disk, as well as use a product key that is not located on the motherboard of the computer.
The older Windows XP cannot run after the motherboard is upgraded. It crashes when an attempt is made to boot from a USB disk. Windows 7 can support being natively boot from a VHD disk, and its boot volume can be located on a USB hard disk. But, the system volume, itself, must be found on an internal hard disk.
After an upgrade to the motherboard, Windows 7 can still work properly, if the computer’s CPU type is not changed (for example, from Intel to AMD). After cloning a Windows 7 to dissimilar hardware, however, a new license key is usually required.
Windows 8 and 10 can run from a USB hard disk, including one holding both the system and boot volumes. In addition, Windows 8, Windows 8 .1 and 10 have a new feature, “Windows to Go”, which allows an installation of Windows 8 on a USB hard disk. However, the feature, Windows to Go, is only available with the Enterprise version of Windows and on Certified Drives. For more information, you can refer to:
In our attempt to make testing and upgrading to Windows 10 as easy as possible for you, the new version of “Lazesoft Recovery Suite” has a new feature, “Install Windows 7/8/10 on one USB hard disk”. The new Lazesoft option can do more things than ‘Windows to Go’. With our new feature, every version of Windows 8/10 can run successfully on USB hard disk. Certified Drives are not required. Any common USB hard disk is good enough. If you list Win 7 on the option, can a user install that version, say on an XP machine? This is not stated very clearly, and might need to be included in several places in this article.

The following is download link of the new beta version of Lazesoft Recovery Suite Home Edition, which allows you to use the new feature, Install Windows 8/8.1/10 on USB disk:

Lazesoft Recovery Suite v4.0

The Lazesoft Recovery Suite, version 4.0, is our first major revision for this year and we’re looking forward to exciting things to come in 2015! First, we have made improvements in the appearance a functionality of our program, and fixed several small bugs. Beyond that, our product is more powerful and easier to use than ever.


Recovering data or repairing your operating system when Windows does not boot normally, or has crashed, is always a headache for Windows users, even for more experienced administrators, because a crash of the Windows system has many possible causes. Some hazards include; virus infections, sudden power loss, or an unexpected deletion of a partition. MBR or DBR failures can happen unexpectedly. System, boot, BCD or registry files can suddenly disappear or become corrupted. Sometimes users accidentally format a disk drive that contains important files or data.


Different repair methods may be required for each reason for a computer crash. We at Lazesoft have helped many users to fix their computer’s boot problems with many explanations. In our attempts to lead our clients in fixing their computer errors, we have frequently noticed that, sometimes, they have no idea of what might have gone wrong. We are trying to reduce the need for specialized computer training by adding the simplest possible options for repairing a computer.


Some users have tried to fix or rebuild their MBR, when, actually their BCD was corrupted. Some have tried to rebuild the boot sector on their boot partition, but we found that their real problem was the corrupted registry files.


We at Lazesoft decided to design our product so that users can fix many of their computer errors by clicking just one button. Now, they can repair a variety of problems without needing to know about which function or button should be used. We think that will be welcome news for users at all levels of expertise.


In this new version, we added a new major and important feature, One Click Repair, to the Windows Recovery module of Lazesoft Recovery Suite. This feature allows users to click the new <One Fix Repair> button to fix most common boot problems, and it is available now.


Users at all levels of computer experience, from beginner to expert, will find the new option especially valuable, because it is totally reversible. All operations performed by this function can be cancelled and undone, if necessary. Not only does a user not need to understand the reason for many computer breakdowns or know the complicated steps to solve problems, files that have been deleted because of accidents or the effects of malware can be restored automatically with our new program version.


Accidentally formatted data partitions are one of the most common reasons for data loss. If this happens, a user can recover the ‘lost’ files or data with the least computer training and effort. We have redesigned and streamlined the Lazesoft data recovery wizard, especially the ‘Undelete’ and ‘Unformat’ functions. Enhanced options can help new users to recover their data more quickly and easily. Not only that, we have added new data backup and recovery sessions to the program options.


One if the most important improvements in the new Lazesoft Recovery Suite is its ability to back up or clone a user’s operating system, partitions OR entire disk from within the Windows desktop, as well as in boot disk mode. Because backing up and cloning system volume/disk are often daily operations. The new version of Lazesoft Recovery Suite can back up or clone system volume/disk on a running Windows desktop, with no rebooting of the computer needed.


You can rely on the people at Lazesoft to work hard to make our Lazesoft Recovery Suite as streamlined and efficient as possible!


In the new version of Lazesoft Recovery Suite, many features have been added and improved. The following are the new features of Lazesoft Recovery Suite 4.0:

Minor bug fixes

Fix the Error “A disk read error occurred. Press Ctrl+Alt+Del to restart”

My computer crashed. I get the error message: “A disk read error occurred Press Ctrl + Alt + Del to restart”, how can I fix the problem?


Technically, this error message comes from your computer’s volume boot sector. When rebooting a MBR based computer, the BIOS reads and runs the MBR boot code. Then the MBR finds an active partition, reading and running its boot sector code. After that, the active partition boot sector code tries to read the system boot file. If the boot sector code fails to read the sectors of a boot file, it reports the error message, “A disk read error occurred. Press Ctrl+Alt+Del to restart”.


A few errors may cause the boot sector code to fail to read the boot file sector and report the error “A disk read error occurred. Press Ctrl+Alt+Del to restart”.

  1. Bad sector
  2. Bad memory
  3. Damaged volume boot sector


In order to fix the error, “A disk read error occurred. Press Ctrl+Alt+Del to restart”, you can try the following steps:

  1. Make sure the computer is set to boot from a non-bootable device, such as a non-bootable USB disk or CD/DVD.
  2. Fix the boot sector using the Lazesoft Recovery Suite boot disk->Windows Recovery->BootCrash->Fix Boot Sector.
  3. Check the disk error using the Lazesoft Recovery Suite boot disk->Disk Image & Clone->Check Disk
  4. Check the memory using the Lazesoft Recovery Suite boot disk-> Windows Recovery->Check Memory

Lazesoft Recovery Suite V3.5 is Released

Happy 2014! This is beginning of a new year, and, like you, we have a lots of plans for the future.


If you are also considering whether to upgrade to Windows 8.1, we have a powerful new version of the Lazesost Recovery Suite available. And it’s totally free of charge.


We think that it is better to try Windows 8.1 on your computer before upgrading it. There is an <Install Windows 7/8 on VHD> feature built into the new version to help you testing Windows 8.1 without resizing the existing partitions. You only need to specify the Windows 8.1 installation DVD drive and the target location to save the virtual hard disk file, and then click <start> button. The program will do the rest. After that you will have Windows 8.1 running on a VHD file, and which can be located in a USB disk. Isn’t that cool?


A Microsoft Surface Pro 2 uses Windows 8.1 x64 with a GPT disk and only supports the UEFI boot mode. More and more computers, especially, laptops only supports the UEFI boot mode. The newest version of Lazesoft Recovery Suite fully supports created boot disks compatible with the UEFI boot mode. When creating a boot disk using our program, you only need to specify the target Windows version as Windows 7 x64, Windows 8 x86, Windows 8 x64, Windows 8.1 x86 or Windows 8.1 x64, and the created boot disk will be compatible with the UEFI boot mode and the BIOS boot model.


The new version of our Lazesoft Recovery Suite has added supports for cloning, backing up or restoring GPT disks; resetting/recovering passwords, and repairing Windows 8.1, all of the features you need to maintain a Windows 8.1 computer.


The following are the new features of in our Lazesoft Recovery Suite 3.5:

Release of Lazesoft Recovery Suite V3.4

It has been a long time since our last release, but version 3.4 of the Lazesoft Recovery Suite is available now. We believe that you will find our improvements very helpful.

Our new bare metal disaster recovery capability means that, when your Windows computer becomes unbootable, even if your hard disk is broken, you still can restore your Windows operating system. With all of the possible threats to your data and files, it is vital that you have a bootable recovery disk (CD/DVD/USB flash disk) which is compatible with your computer hardware.

When you use the Lazesoft Recovery Suite, version 3.4, you can rest assured that your work and data are safe. Using our software, you can create a bootable recovery disk which is able to work seamlessly with your hardware and software, booting your computer normally after almost any problem that could occur.

At Lazesoft we know that no single type of boot disk 100% is compatible with all Windows computer hardware. There are too many computer hardware manufacturers and types of hardware. From our extensive experience, we have found that Linux-kernel based bootable disks are compatible with about 60% of all Windows computers, but that WinPE based boot disks have about 90% hardware compatibility.

Because we want to offer you the most compatible and flexible data and system recovery software possible, we have concentrated on improving our Lazesoft Media Builder, the bootable disk creation software in our software suite. The new version of our software has added options designed to be WinPE friendly, allowing you to specify the different type of WinPE version needed when you are creating a bootable disk:
Windows 7 32 bit (WinPE 3.3 32 bit)
Windows 7 64 bit (WinPE 3.3 64 bit)
Windows 8 32 bit (WinPE 4.0 32 bit)
Windows 8 64 bit (WinPE 4.0 64 bit)

In 90% of all situations, you will not need the ‘Options’ on the home page of ‘Media Builder’. But, if you happen to be one of the other 10%, whose computer has a hardware compatibility problem with the default, settings in Lazesoft Media Builder, simply set the correct WinPE version when creating a bootable disk.

The following are some tips related to certain ‘special’ issues:

*For a Netbook computer having Inter Atom CPU, you probably get 64 bit compatibility problem, please choose the Windows 7 32 bit.

*For a new Windows 8 computer with touch screen, which does not have mouse, please choose Windows 8 64 bit. Under a Windows 8 PE based bootable disk, you can use your touch screen.
*If you are using an older, or specially built computer, please contact us. We will provide Linux kernel based or Bart-PE based CD ISO file for you.

With our new Lazesoft Media Builder, version 3.4, you can easily work with any custom drives in those rare cases that your hard disks are not recognized by a WinPE boot disk.

Many users have reported low backup speed and large backup image files when using the last version of our product. In order to further improve our product, we have redesigned our backup file format and backup engine, keeping them fully compatible with our earlier products. With our latest program version, you will have much faster processing times and much smaller backup files.

You can check out our test report. We welcome you to test our new version and share your testing result. You can find the report here:

Here are even more improvements to our latest Lazesoft Recovery Suite:

Mac OS HFS file system data recovery is fully supported.

The original date and time stamps will be recovered with an NTFS file system

You can choose single or multiple partitions to back up or restore in a session

Enhanced disk cloning by automatically updating the disk signature on your target disk and system, as well as supporting the cloning of multiple partitions

Enhanced password recovery for Windows 8 by forcing a modified file flush on the disk and handling Windows Local Security Policy more accurately

Windows can be prevented from going to sleep or hibernating during long tasks.
