choiced secure boot and create ventoy udisk.
followed UEFI mode secure boot operation description (UEFI模式安全启动操作说明)
when i move to select key step. and select ENROLL_THIS_KEY_IN_MOKMANAGER.cer.
the system shows "Unsupported Format"
It says "Only Der encoded certificate(*.cer/der/crt) is supported"

what can i do?

Is this at all possible ....

Create a bootable usb using Rufus
Somehow extract an iso image of the same
Use from within Ventoy

Any simple reason why this would NOT work?

Just want to say thank you to longpanda and everyone else involved with Ventoy, it truly is a great tool and has made my life much easier.

Cheers

我想使用linux中的grub2启动ventoy的启动分区，应用os-prober自动搜索功能貌似不行。哪位大神有启动ventoy分区的语法？
I want to boot ventoy's partion with grub2 of linux. but os-prober can not detect the ventoy partion. What can i do ?

I have a laptop, (some kind of HP Notebook), with Windows 10 and a SSD-hard drive with the total capacity about 250 Gigabyte. After a lot of "work" I managed to shrink the partition C from Windows 10 and I could then create a new partition on the same drive. I made the second partition as a 19 Gigabyte NTFS, and as I expected it is called D: . My plan was to use this second partition for Ventoy and I would like to keep Windows "unharmed".  My hope was, if I first create this second partition from Windows it would be easy to know where I am installing Ventoy and bee sure I don't harm Windows.
When I ran Ventoy2Disk I discovered that I could not select only D:
 I was sad to see, the only possible option was to select booth C: and D: so I did not dare to continue, because i was afraid to harm Windows. On an older computer I managed to install Ventoy on a secondary hard drive (that computer had some room underside dedicated to add an SATA-drive), and it worked great. I could use it for Live-sessions with Xubuntu (using boot override) and I was still able to use Windows when I needed.

My newer computer have no place for a second harddrive. Is it impossible to install Ventoy on the same drive as Windows and keep the opportunity to use Windows sometimes? 
 ( i live in Sweden, and there could bee errors in spelling, I am not very good at speaking English but guess what?, my first Computer was the "Commodore Amiga 500" and it was never sold with any OS with Swedish support, so you can say I have no problems to use (or read) systems in English, but the people I meet everyday often only speach Swedish so I am not very fast or good at find the perfect word). Thankyou / Thanks to anyone who have an advice , or an answer to my question about the "single hard drive problem".
Kind regards from a micro-computer user in Sweden.

现在设置启动菜单超时时间后是在等待一定时间后自动进入特定系统,对于常用主系统,偶尔用用其它系统的这个等待时间颇为影响启动速度,能否改成启动时检测某个键是否被按着,是则显示菜单,否则不显示菜单直接进入主系统

Let's say i have an iso that is NOT compatible with Ventoy. So i burn this to a DVD media and check that it boots on my windows laptop.  Then i rip/pull the image from the DVD media in iso format.  Should this iso have a greater or full chance of NOW booting from within  Ventoy?

Ventory 1.0.74 legacy boot linux vdisk(vhd) lead to black screen.  but win10 vdisk(vhd) boot success.

So I rollback to 1.0.73 boot success both win10 and linux.

[ventoy_grub.cfg]

```
menuentry "Windows 10" --class=windows {   
    set vdisk_path="/Images/Win10.vhd"
    if search -n -s vdiskhd -f "$vdisk_path"; then
        vhdboot_common_func "($vdiskhd)$vdisk_path"
    else
        echo "$vdisk_path not found"
    fi
}

menuentry "Manjaro" --class=manjaro {

        vtoyboot_common_func "($vdiskhd)$vdisk_path"

Hello!

I believe I've followed the directions for the install correctly. I have a 120GB SSD I put into an external enclosure. I ran Ventoy2disk to install it on the SSD and I copied a couple ISOs to the open partition. I tried a laptop with Secure boot on and off and the computer doesn't detect the drive. I had a 4GB USB stick spare and installed Ventoy and it boots fine.

Is this just an issue with the computer not detecting my SSD in the external cage or am I missing a setting on the install to the SSD? Thank you for your assistance!
