Ventoy windows 11 and memtest86

I would like to use ventoy to put windows 11 and memtest86 on a flash drive.

This guide mentioned GPT is recommended. Is that accurate? Ventoys default setting was MBR. Is that ok? Will I have problems?

GPT or MBR partition style​

For most modern machines, GPT is the recommended default. Every PC running Windows 11 uses UEFI firmware, and the Ventoy GitHub repository (December 2025) confirms that both MBR and GPT are fully supported. The main reason to choose MBR is hardware old enough to lack UEFI entirely in that case, GPT-formatted removable media may not be recognized at boot.

For a Windows 11 and MemTest86 toolkit specifically, GPT on a UEFI machine keeps everything consistent. Current MemTest86 versions (v5 and later) are UEFI-only and will not load in legacy BIOS mode, as documented on Unix Stack Exchange (2021). If the target machine runs UEFI, use GPT. If it doesn't, weigh whether MemTest86 v4 (the legacy-compatible version) covers your needs before committing to MBR.

Yes I would use GPT with Ventoy if you are booting windows from a GPT disk. Ventoy
