Since version 2.7 kon-boot can be installed only by using our GUI installer. Internet connecton is required for installer to work. Please note that all other installation options like CD installation are depracated (older kon-boot version is included in the package for compatibility reasons or in case of temporary lack of Internet connection).
We recommend using USB pendrive with less than 16 GB capactity, although it is not necessary (some older BIOSes have problems with kon-boot loading from larger USB pendrives).
Please use USB pendrive manufactured by reputable company like KINGSTON, SANDISK, SONY. Please don't use USB pendrives from 'NO-NAME' companies - they may cause problems on various BIOSES.
Following video presents installation to USB pendrive media:
Available for kon-boot v2.6 (if you use this feature in kon-boot v2.7 the older version (2.6) will be installed)
Requirements:
Please note: files located on your USB thumb drive may be overwritten!Installation steps:
Starting from 3.5 version (commercial licenses) Kon-Boot is able to bypass Secure Boot protection on PCs (excluding Apple computers). Following tutorial explains how to boot Kon-Boot while the Secure Boot option is enabled in BIOS:
Starting from 3.5 version (commercial licenses) Kon-Boot is able to bypass Secure Boot protection on PCs (excluding Apple computers). See Secure Boot Bypass for details.
In order to use Kon-Boot in UEFI mode you need to make sure that the UEFI BIOS is not configured to use Secure Boot feature. Secure Boot feature is typically disabled however in case of any problems please enter the BIOS setup and disable the Secure Boot option manually (see examples below).

Disabling Secure Boot feature on Lenovo:
Alternative approach:
If you still have problems check out other youtube videos tutorials on this topic.
Newer Windows version use Virtualization-based Security (VBS) and/or hypervisor security. This can cause BSODs (Blue Screen Of Death) during loading Windows with Kon-Boot (Kon-Boot does not support virtualization). In order to prevent this from happening go to your BIOS setup and temporarily disable virtualization support (VT/VT-x) as presented on screenshots below.
This step is optional, try it if you experience Blue Screen of Death during booting your target Windows machine with Kon-Boot.
Following screenshots present how to disable virtualization support on various BIOSES (don't forget to SAVE the changed settings).
Starting from version 2.7 (commercial edition only) kon-boot allows user to run automatic powershell script just after the boot of target operating system. Powershell script of user choice is being run with full system rights. This gives excellent and very powerful opportunity for the forensics team to gather all the necessary data from the target system. Right now the feature works only in UEFI mode and on Windows 8 / Windows 10 systems (x64).
Following video presents this feature at work:
In order to use this feature just edit the 'auto.ps1' file on your kon-boot USB media.
It seems rather unlikely. Legacy BIOS Kon-Boot loader is very hard to maintain, additional unscheduled constant Windows 8 / Windows 10 security updates do not make things easier. Finally UEFI is now recognized as the BIOS replacement. Check our faq for more detailed answer on this topic.
What's Sticky Keys Feature?Sticky keys is a new Kon-Boot escalation feature which allows user to spawn a console window with system admin rights before the user is logged in. Kon-Boot allows you to get console window while the Windows login screen is still active.
Requirements:
Usage steps:
Video tutorial available below:
Following commands should be typed manually in the console:
Please note: this is only for local accounts:
To change your password you can try the following way (after booting with kon-boot):
After restart:
You can change your local account password by using the Sticky Keys Feature and using following commands:
net user username newpassword
where the username is the name of the local account and newpassword is the new password for this local account. Please note this is only for local accounts.
You can delete your local Windows account by using the Sticky Keys Feature and using following commands:
net user username /delete
where the username is the name of the local account.
So in case of kon-boot account, type:
net user kon-boot /delete
and press enter.
If you experience 'password has expired and needs to be changed' error during your login attempt it simply means that your password has expired. This is caused by custom Windows password policy not a problem of Kon-Boot itself.
To fix this issue (after booting the target Windows OS with Kon-Boot):
net user username /expires:never
(where username is the target user name)net user username newpassword
(where username is the target user name)It should be possible to unlock a locked Windows account by using the Sticky Keys Feature:
net user username /active=yes
(where username is the target user name)If this is a domain account please try:
net user username /DOMAIN /active:YES
(where username is the target user name)Please note Kon-Boot is a tool for bypassing passwords not really designed for unlocking so this information is just 'extra'.
UPDATE 05.2018: Windows 10 online account authorization bypass was added to the 2.8 Kon-Boot Release (commercial licenses only, UEFI systems only).
Following video completely illustrates this entire process:
As for personal licenses:
Personal licenses does not offer online authorization bypass on Windows 10 systems. However user can still access the system as local administrator. In fact in the kon-boot v2.5 administrator account can be added automatically, as presented in the following scenario:
In case of problems (i.e. when message box was not displayed) you can add the administrator account manually using the sticky keys feature. Please see the Sticky Keys Feature for further details.
If you account is an online (live) Windows 10 account and you have a commercial Kon-Boot license (commercial kon-boot licenses allow to bypass Windows 10 online/live passwords (UEFI)) you can bypass the Windows HELLO authorization as well.
Please notice: for online/live password bypass option to work it is necessary to wait approximetely ~5minutes after Windows login screen appears (Kon-Boot message box should be displayed on the screen when things are ready).
