We recommend using USB pendrive with less than 16 GB capactity, although it is not necessary (some older BIOSes have problems with longky.mobi 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.

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 longky.mobi (longky.mobi 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 longky.mobi.

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) longky.mobi 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 longky.mobi USB media.

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

It seems rather unlikely. Legacy BIOS longky.mobi 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.
