本人使用的是Ventoy启动盘(D:)，已关闭设备加密（BitLocker），UEFI设置为“从U盘启动”。卡巴斯基救援磁盘镜像位于D:\Rescue Disk\Kaspersky\krd.iso。我还创建了2GB的D:\Rescue Disk\Kaspersky\persistence.dat和D:\ventoy\ventoy.json（内容如屏幕截图 2026-05-04 221800.png所示，纯文本如下），目的是在U盘持久化部署病毒库。

已从Ubuntu发布页（https://packages.ubuntu.com/zh-tw/questing/all/linux-firmware/download跳转security.ubuntu.com/ubuntu）下载了linux-firmware_20250901.git993ff19b-0ubuntu1.10_all.deb，并改为.tar.gz后放在U盘根目录（如屏幕截图 2026-05-04 222053.png所示）。从U盘的krd.iso启动时，Boot in grub2 mode和Kaspersky Rescue Disk Limited Graphics mode都没有用，报错问题（如屏幕截图 2026-05-04 215306.png所示）仍然存在。

Hello.

1) linux-firmware works only in ISO mode. See https://support.kaspersky.com/krd/24/294012. DD mode or direct ISO loading (Ventoy as example) unsupported.

2) persistence.dat file is KRD 2018 feature. On KRD 2024 was used persistent partition. See https://support.kaspersky.com/krd/24/292858

3) Unfortunately no reliable way to do what you want.

I see. Thank you for your reply.
