Official FAQ

I have checked the official FAQ.

Ventoy Version

1.0.53

What about latest release

Yes. I have tried the latest release, but the bug still exist.

BIOS Mode

Both

Partition Style

MBR

Disk Capacity

256GB

Disk Manufacturer

SanDisk

Image file checksum (if applicable)

No response

Image file download link (if applicable)

No response

What happened?

note: I don't know whether this is on MBR or GPT so I said MBR

When I boot into ventoy, it says there is a syntax error in ventoy.json. I have tried copying and pasting examples directly from ventoy.net , and using IDE's to look for errors and fix them, but it still doesn't work. When I press enter ventoy launches with default settings. I have tried both BIOS and UEFI modes.

update: I copied json file into jsonparseronline and it had no errors

steve6375 · 2021-10-07T18:48:25Z

Sorry, but I cannot see the file from here and I don't have my crystal ball. Maybe you could attach the file to your post?

ventoy · 2021-10-08T14:47:35Z

@MrQuasar173
Please attach ventoy.json for check.

MrQuasar173 · 2021-10-08T16:30:17Z

It won't allow me to attach a JSON file. Here is is copied and pasted

{
    "password": {
        "bootpwd": "test"
    },
    "theme_legacy":{
        "file":"/ventoy/themes/Vimix/theme.txt",
        "gfxmode":"1024x768"
    },
    "theme_uefi":{
        "file":"/ventoy/themes/Vimix/theme.txt",
        "gfxmode":"1366x768"
    }
}

ventoy · 2021-10-09T02:28:55Z

I test this and it does not report syntax error.
You can change the suffix or compress it and attach the file (e.g. ventoy.json.txt/ventoy.json.zip)

MrQuasar173 · 2021-10-11T22:16:05Z

Ventoy_json.zip
Sorry for late response here you go

ventoy · 2021-10-12T02:39:27Z

The ventoy.json you attach is different from what you pasted before and has too many syntax errors:

{
    "theme_legacy": [
	{
        "file": "/ventoy/themes/Ventoy-Dark/theme.txt",
        "gfxmode": "1024x768"       
		},
    "theme_uefi": {
        "file": "/ventoy/themes/Ventoy-Dark/theme.txt",
        "gfxmode": "1366x768"

    "theme_ia32": {
        "file": "/ventoy/themes/Ventoy-Dark/theme.txt",
        "gfxmode": "1366x768"
		},
    "theme_aa64": {
        "file": "/ventoy/themes/Ventoy-Dark/theme.txt",
        "gfxmode": "1366x768"
		},
    "theme_mips": {
        "file": "/ventoy/themes/Ventoy-Dark/theme.txt",
        "gfxmode": "1366x768"
		}
	],
	
	"injection": [
        {
            "image": "04._Windows_XP_Professional_SP3_32bit.iso",
            "archive": "ventoy/drivers/DPMS_XP/DPMS.7z"
			},
		{
            "image": "07._Windows_8.1_Update_1_32bit.iso",
            "archive": "ventoy/drivers/EI/ei.zip"
			},
		{
            "image": "08._Windows_8.1_Update_1_64bit.iso",
            "archive": "ventoy/drivers/EI/ei.zip"
			}
    ],
	
	    "auto_install": [
        {
            "image": "08._Windows_8.1_Update_1_64bit.iso",
            "template": [
                "/ventoy/unattended/unattended_w81_64bit.xml",
            ]
        },
		{
		    "image": "08._Windows_8.1_Update_1_32bit.iso",
            "template": [
                "/ventoy/unattended/unattended_w81_32bit.xml",
            ],
		}
    ]

}

This is the correct content:

    "theme_legacy": 
	{

        "gfxmode": "1024x768"

    ]

@MrQuasar173 Any update?

MrQuasar173 · 2021-10-17T16:02:28Z

Here is updated json file with just the themes following your syntax. It still doesn't work
ventoy.zip

steve6375 · 2021-10-17T22:36:48Z

What do you mean by 'doesn't work'?

ventoy · 2021-10-18T02:20:41Z

@MrQuasar173 It still report syntax error?

MrQuasar173 · 2021-10-18T02:21:36Z

Yes

ventoy · 2021-10-18T02:45:49Z

OK, after the report, you can still boot into Ventoy's main menu.
Here you press c to enter grub shell and run

md5sum  $vtoy_iso_part/ventoy/ventoy.json

It will output the md5 of the ventoy.json you use. Take a photo about it and upload the photo.

@MrQuasar173 Any update?

MrQuasar173 · 2021-10-23T16:36:40Z

Here is the screenshot

MrQuasar173 · 2021-11-07T18:55:58Z

@ventoy any idea what's going on here?

ventoy · 2021-11-08T03:37:59Z

The problem is that the ventoy.json you give is in UCS-2 encoding, Ventoy need UTF-8 no BOM encoding.
So you need to convert it to UTF-8 no BOM
I will add a check in the next release for this.

MrQuasar173 · 2021-11-08T04:07:12Z

Ok, Thanks! I will look up how to change the encoding and then close this issue if it works

ventoy.json must in UTF-8 encoding. The BOM is auto skipped if exist.

ventoy · 2021-11-10T12:46:21Z

@MrQuasar173 Any update?
