This page describes lists common problems related to Dell hardware (mostly laptops and servers). Note that some problems affecting also Dell are more universal, and listed on this page.
Some Dell OptiPlex models in USFF cases (mainly with Core 2 Duo CPU, eg. OptiPlex 780 USFF, possibly also others) have problems with recognizing drives in pre-boot stage, when USB ports are overloaded. In effect, such computer seems to freeze just before detecting drive(s) and booting - problem repeats until some USB devices are disconnected.
Some early-UEFI (2013 and older) Dell PowerEdge servers don't work properly with 32-bit version of Kali Linux.
Solution: always have both versions of Drive Badger: 32-bit and 64-bit.
The whole screen is black and there is no blue boot menu (unlike on the below picture).
As for Dell, it affects mostly desktops with Radeon cards, and probably not fully compatible monitors. See this problem description.
This error is very commonly confused with the previous one. In this scenario, boot menu is properly displayed - user can even switch between standard view and boot details for each menu entry. However right after trying to boot anything, computer hangs with black frame.
It happens exclusively on 64-bit Dell hardware that supports UEFI.
Don't forget to restore previous settings after finishing exfiltration.
Some Dell PowerEdge servers (at least T- and R- series) don't recognize Kingston DataTraveler G3/G4 pen drives properly - and can't boot from them, even in USB 2.0 mode.
Solution: consider using the recommended USB drives (or better, external SSD drives, which have much better write performance).
