Gamingdeputy reported on May 4 that Riot Games deployed a patch for “League of Legends” (international server) on May 1, introducing a new Vanguard system designed to curb “scripts, bot players, and cheaters.”
Subsequently, some “League of Legends” players reported that after updating the game to version 14.9, the Vanguard program appeared in the background, and then found that their computers could not start normally, and either fell into an infinite restart loop, or were forced to delete the driver.

In this regard, Riot Games published a long article on Reddit to explain, stating that Vanguard will not cause the computer to be unable to start. Currently, “no more than 0.03% of players have reported Vanguard issues”, but after checking, they found that it was not Vanguard. caused.
To date, we have not confirmed any cases of hardware not booting due to Vanguard, but for players who are experiencing issues, we strongly recommend that you contact customer support so that we can investigate and provide assistance. So far, we've individually addressed some of the things you may have seen before about users claiming their machines were experiencing this issue, and confirmed that Vanguard is not the root cause of such issues.
About 0.7% of gamers bypassed Microsoft's TPM 2.0 mandate when installing Windows 11, but Vanguard .0 requires TPM 2.0 to be enabled in order to run, which requires changing BIOS settings, depending on the motherboard manufacturer. Vanguard cannot and does not make changes to the BIOS.
BIOS settings can cause some confusion for gamers, and we've encountered two specific situations that can cause problems before.
The first situation is that many brands of motherboards will prompt to switch to UEFI mode when TPM 2.0 is enabled, but if your existing Windows 11 system is installed on an MBR partition, the system will not boot after the change. Some OEMs can support TPM 2.0 in LegacyBoot mode, but to support UEFI mode Windows 11 must be installed on a GPT partition. Microsoft has provided the required UEFI setup guide and its tools to save you the trouble of repartitioning/formatting and reinstalling the system if you encounter this situation.
In the second case, we discovered that a player accidentally enabled Safe Boot with highly customized settings. Although Vanguard requires secure boot to be turned on in Valorant, we have not applied it to League of Legends, mainly because League of Legends players generally use older hardware, and older computers may suffer from this setting. Compatibility issues are one of the main reasons for the delay in the launch of Vanguard.
For example, some GPU (especially older graphics cards) firmware does not support UEFI secure boot, which may be due to the fact that the “unlocked” firmware flashed by the player itself is not effectively signed. In this case, enabling Secure Boot will result in the GPU not functioning properly, ie a black screen. There are two ways to solve this problem:
Connect the monitor to the integrated graphics card (if you have one) and disable Secure Boot in the BIOS.
Remove the CMOS battery to reset the BIOS to default settings (Gamingdeputy reminds: Some motherboards have jumpers or switches to restore default settings. Short-circuit or press the switch to restore default settings).
Of course, although “League of Legends” will not force users to enable the safe boot function, it will have no impact if it is turned on. For ordinary users who don’t know how to troubleshoot and solve the above problems,Don't enable Safe Boot Mode unless you absolutely want to enable it.
