The Ventoy drive works on one PC and is invisible on another: you hammer the boot key, the boot menu opens - and there is no USB entry at all. Before suspecting the drive, know that most PCs hide USB booting behind timing, a fast-boot setting, or the wrong entry name. This guide walks the checks in the order that finds it fastest.

The full guide video shows a real boot sequence and the Ventoy menu appearing - compare it with what your PC does
Start with the test that splits this problem in half: plug the same Ventoy drive into a second PC. If it appears there, your drive is innocent and everything below is about this one PC's firmware. PCs can hide a USB drive for boring reasons - the stick was inserted after power-on, Fast Boot skipped initialising USB, you are pressing the wrong key, or the entry is sitting in the list under a name you did not recognise.
A typical one-time boot menu - the USB is there, under two possible names
Windows Boot Managerinternal disk
UEFI: SanDisk, Partition 1choose this for modern installers
SanDisk (without UEFI)legacy entry - same stick
Enter SetupBIOS settings
Many PCs list the same stick twice - the UEFI entry and the legacy entry. For Windows 11 and modern Linux, the UEFI one is correct

Timing and the Right Key - the Free Fixes First
Insert the USB before switching the PC on - some firmware only inventories devices present at power-on
Start tapping the boot-menu key immediately and repeatedly: F12 on most Dell and Lenovo, F9 on HP, F8 on many Asus boards, Esc on several others - the exact key is shown briefly on the maker's logo screen
If Windows loads instead, you missed the window - restart and tap earlier; on Windows 10/11 you can also hold Shift while clicking Restart, then choose "Use a device"
Scan the whole list, including entries named only by brand (SanDisk, Kingston) or "UEFI: USB" - the word Ventoy never appears in the firmware's list

BIOS Settings That Hide USB Drives
Fast Boot: on several boards, Fast Boot skips USB initialisation during POST - disable it in the BIOS while troubleshooting
USB Boot / Legacy USB Support: make sure USB boot is not disabled; some business BIOS profiles lock it off
Try a different port: on older boards, use a rear USB 2.0 port - some early USB 3.0 controllers only wake up after an operating system loads its driver
Avoid hubs and front-panel extensions for the test - plug the stick directly into the motherboard port

The Entry Appears but Returns or Errors Immediately
If selecting the USB drops you straight back to the menu, or a Secure Boot message flashes, the drive is being found but blocked - that is the Secure Boot enrolment case, covered in its own guide in this series
If there are two stick entries, try the other one - a Legacy entry on a UEFI-only-configured drive (and vice versa) can fail instantly
On a freshly made drive, also confirm the drive actually boots somewhere: the second-PC test from the intro separates PC settings from a bad Ventoy install in one minute

Last Resort - Rebuild With the Other Partition Style
A small number of firmwares are picky about partition style: if the drive was installed as GPT and a very old BIOS-only PC cannot see it, reinstalling as MBR (Option - Partition Style in Ventoy2Disk) is the classic cure - and the reverse helps on a few strict modern boards
Remember that Install erases the whole drive - copy your ISOs off first
Reinstall, copy the ISOs back, safely eject, and test on the problem PC first this time
If the stick boots on every other PC and never on this one even after all of the above, accept the honest answer: that firmware and USB booting do not get along, and a different stick model sometimes succeeds where this one cannot
Watch a Correct Ventoy Boot in the Video
See the boot menu entry, the version line and the ISO list as they should appear on a healthy setup.
Why does the same USB boot on my laptop but not on my desktop?
Because boot menus are firmware, not standards - each maker inventories USB devices differently. Fast Boot skipping USB, a disabled USB-boot option, or a port that wakes late are desktop-side settings; the drive itself is proven good by the laptop test.
Should I pick the UEFI entry or the plain entry for my USB?
For Windows 11 and current Linux installers, pick the entry beginning with UEFI:. The plain entry is the legacy BIOS path for the same stick - useful on old machines, wrong for modern installers, which may refuse Secure-Boot-era hardware checks when started in legacy mode.
My BIOS shows no boot menu key option at all. How do I boot the USB?
Enter the BIOS setup (usually Del or F2), find the Boot section, and either enable the boot-menu key (often called F12 Boot Menu) or move the USB device above the internal disk in the boot order temporarily. Save and exit - the PC will then try the USB first.
