Ventoy for PARAVIS Flash

Ventoy 1.1.18 sources and Paravis changes used on the PARAVIS multiboot USB flash.

The PARAVIS flash uses a non-standard partition layout, so Ventoy has to be patched to find the data (ISO) partition dynamically instead of assuming partition 1:

#	Size	File system	Label	Purpose
1	16 GB	FAT32	PARAVIS	main boot partition (bootmgr / g4d)
2	32 MB	FAT	VTOYEFI	Ventoy EFI partition
3	rest − 3 MB	exFAT	DATA	images and data

The data partition is detected by the marker file /ISO/Ventoy/NOT.DEL.

Applying the patches

The scripts take explicit paths, so they can be run from any checkout.

# 1. GRUB2 sources (run inside the Ventoy build tree)
python3 paravis/patch_ventoy_layout.py GRUB2/SRC/grub-2.04/grub-core/ventoy

# 2. VTOYEFI grub.cfg
python3 paravis/patch_ventoy_grubcfg.py vtoyefi/grub/grub.cfg

# 3. initramfs hook
python3 paravis/patch_ventoy_hook.py ventoy.cpio ventoy.cpio

# 4. vtoyjump32.exe / vtoyjump64.exe
python3 paravis/patch_vtoyjump.py <dir-with-vtoyjump-binaries>

# 5. default menu language
./paravis/patch-ventoy-lang.sh vtoyefi/grub/grub.cfg

patch_vtoyjump.py patches compiled binaries; it is safe to re-run and skips files that are already patched.

Theme

paravis/theme/ contains theme.txt, ventoy.json, the background and widget PNGs and paravis.pf2 (Montserrat converted to GRUB format).

ventoy.json refers to tahoma20.pf2, tahoma16.pf2, tahoma-bold16.pf2 and tahoma-bold14.pf2. Those files are not part of this repository because they are derived from Microsoft fonts. Provide them locally when deploying the theme, or generate replacements from a font you are allowed to use:

grub-mkfont -s 20 -o tahoma20.pf2 YourFont.ttf

build-theme-main.py renders the background and a preview from a layered PSD file; it needs psd-tools, Pillow and the Montserrat font.

What is not included

This is a source-only repository. It does not contain:

• private keys, certificates or signed EFI binaries (keys/, *.signed);
• Microsoft-derived font files (tahoma*.pf2, segoeui18.pf2);
• built Ventoy releases and bootable images (*.iso, *.img, *.wim, *.esd, Data.pf);
• bootice.exe, Total Commander and other third-party binaries;
• build output, logs or local machine paths.
