Cloned the Drive to make a backup in March 4. Decided to Install ubuntu 18.04 on USB stick from another USB stick All working OK. Can F9 on boot and can see in boot options UEFI windows and UEFI Ubuntu. Both boot fine, Ubuntu runs off of a 64gb usb stick 5. Windows partition crashes/gets corrupted won't boot. Try to boot into USB by going to boot Menu or manager and then from there select the USB Installer. If it didn’t work then you have to change your USB and do the steps once again.

Apple has already released the Macintosh operating system on 20 September of 2016, and if you want to give a try to this OS, then you are in the right place because here you will learn the complete process of how to dual boot Windows 10 and macOS Sierra 10.12, Hackintosh on PC.

What's Kon-Boot for Windows?

Kon-Boot (aka kon boot, konboot) is an application which will silently bypass the authentication process of Windows based operating systems. Without overwriting your old password! In other words you can login to your Windows profile without knowing your password. Easy to use and excellent for tech repairs, data recovery and security audits. Fast, tiny and gets your job done!

That makes me think that there’s some problem with your USB’s bootloader. Make sure you followed all the instructions above about creating the boot disk with Etcher. That process is crucially important. Without a properly-formatted Ubuntu Live USB, you won’t be able to boot into Ubuntu on the USB drive.

Kon-Boot in action:

How to purchase?

Kon-Boot is currently the only solution on the market which can securely bypass Microsoft Windows / Appple macOS passwords.

Notable differences between personal and commercial version

Installation to USB

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:

Manual installation to USB

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:

• Your BIOS need to be configured to start from the USB media. If you don't know how to configure your BIOS please check external video tutorials - here
• USB thumb drive (FAT32 filesystem)
  

Please note: files located on your USB thumb drive may be overwritten!Installation steps:

1. Insert your target USB pendrive

UEFI and Secure Boot feature

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).

Above: UEFI Secure Boot option on ASRock motherboard

Above: UEFI Secure Boot option on Samsung motherboard

Disabling Secure Boot feature on Lenovo:

1. Set Secure Boot option to disabled
2. In the 'Restart' tab, select 'Disabled' for 'OS Optimized Defaults' option and accept potential warnings
3. In the 'Restart' tab select 'Load Setup Defaults' option and accept the displayed warnings
4. Exit and save changes

Alternative approach:

1. Set Secure Boot option to disabled
2. Set the 'OS Optimized Defaults' to 'Other OS'
3. Use the 'Reset to setup mode' option in one of the BIOS tabs
4. Exit and save changes

Disable virtualization support in BIOS

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).

Automatic Powershell Script Execution Feature

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.

Will this feature be added to normal (legacy) BIOS mode?

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.

Sticky Keys Feature

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:

• Windows operating system booted with kon-boot
• Sticky keys must be enabled in your target Windows system (they are by default)
• Kon-bootV2.1 and higher

Video tutorial available below:

Following commands should be typed manually in the console:

How to change profile password?

Please note: this is only for local accounts:

To change your password you can try the following way (after booting with kon-boot):

1. Navigate the Start Menu to Control Panel
2. Select 'User Accounts and Family Safety'
3. If the User Account Control window appears click 'Yes' and leave the password field empty
4. Select 'Create a new account'
5. Create the account (pick a name) and set the permissions (administrator).

2. Navigate the Start Menu to Control Panel
3. Select 'User Accounts and Family Safety'
4. Select the target User Account (the one you want to change)
5. Select 'Change the password'
6. Input the new information for the account and click 'Change password'
7. You are done

Password expired

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):

1. Use the Sticky Keys Feature to activate the administrator console
2. Type: net user username /expires:never (where username is the target user name)
3. If previous step was not enough, try typing: net user username newpassword (where username is the target user name)
4. Reboot for changes to take effect

Locked account (account unlock)

It should be possible to unlock a locked Windows account by using the Sticky Keys Feature:

1. Use the Sticky Keys Feature to activate the administrator console
2. Type: net user username /active=yes (where username is the target user name)
3. Reboot for changes to take effect

If this is a domain account please try:

1. Use the Sticky Keys Feature to activate the administrator console
2. Type: net user username /DOMAIN /active:YES (where username is the target user name)
3. Reboot for changes to take effect

Please note Kon-Boot is a tool for bypassing passwords not really designed for unlocking so this information is just 'extra'.

Windows 10 Online Authorization Support

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:
