Can't boot in UEFI on my MSI laptop with 256GB external drive

[Nimon77]

Machine: MSI GE72MVR-055

BIOS: On this machine I'm unable to find the drive in UEFI mode (in legacy it works) but if I use a smaller drive like an 8Gb USB stick it worked:

Machine: ASUS N75S

BIOS: On this machine everything is working fine I can boot on the 256Gb drive in ventoy :

This is my drive I only create a 25,55 partition for the test but that still doesn't work:

8GB ok, 256GB not OK. I have no idea about this, sorry.

@Nimon77 What about the latest release?

[Nimon77]

Hello, @ventoy thanks for reply, there is still nothing in UEFI 😢

When you install Ventoy, select MBR/GPT for partition style, test both of them to see whether something different.

What exactly is the 256gb drive ?

Hello, you can see info bellow :

I'm actually in GPT but I can't test MBR right now because I have to much data on the drive, I will try as soon as I can transfer all my data

Transcend JetFlash 920 USB 3.x 256GB flash drive has the same issue. The BIOS boot options menu of MSI's laptop Delta 15 cannot display it. I think I have tried all Ventoy install options except for the LiveCD solution. [Note] The BIOS of MSI's laptop Delta 15 is UEFI only. Cannot boot from a legacy USB at all.

There are four possible Ventoy install options/configurations MBR non-secure MBR secure boot GPT non-secure GPT secure boot Please test each one and report back.
