Hi,

So, Ventoy seems to be working fine with untouched Windows 10 ISO, but if I modify the ISO by adding the ei.cfg into the sources folder, the iso won't boot with the following error:

ASSERT_EFI_ERROR (Status = Invalid Parameter)
ASSERT [Ventoy] /home/share/Ventoy/EDKII/edk5-edk2-stable201911/MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c(813): !EFI_ERROR (Status)
No bootfile found for UEFI!
Maybe the image does not support X64 UEFI!

I saw this error in some other searches from google, but no response. I was wondering, is there something that needs to be done to make the iso properly bootable?

I used this guide to make the modified ISO:

https://www.wintips.org/how-to-edit-iso-...ble-image/#

It works when I use rufus to write the iso to a usb stick (my current Windows install was done with this modified ISO, before I discovered Ventoy). Also, when I mount both then use Beyond Compare to diff the 2 mounted drives, only the ei.cfg is different. There must be some structure type thing for ISOs I don't know about? Any suggestions?

Thanks

Dear all,

After numerous attempts with various programs to create a working multiboot usb stick, I finally succeeded with Ventoy. So I thank and congratulate the author for providing an excellent piece of software.

I am working on linux (mainly Mint 18), on an Asus CM6330 desktop with an intel i7 cpu, dating from 2012. I eventually used a new Sandisk Ultra 32 GB usb stick.

One problem which I had to overcome to get Ventoy working effectively was to format the main partition on the usb stick as ext3 (using Gparted), after installing Ventoy on the stick. If the default fat format of the partition was used, I could copy isos to the stick, and activate the Ventoy menu when booting, but no iso would load (whether in legacy or uefi mode). It is possible that the problem is limited to some rather old machines, but I suggest that the Ventoy documentation should indicate the desirability for linux users of formatting the main partition on the usb stick as ext3 after installing Ventoy on the stick.

Best wishes,
Peter Stone

Hi,

I can boot without any issue using Ventoy if the BIOS of the PC is configured in CSM mode.
If I disable the CSM mode (and do NOT set the secure boot), then I can't boot on the Ventoy USB stick.
This could not be a problem but I "think" that, when I boot with the BIOS in CSM mode, this prevents my Mageia iso to be able to reconfigure the boot loader in case I need to do it.
I'd like to test to launch the Mageia iso with BIOS NOT set to CSM mode.
My question : do you know how to do to have the Ventoy USB stick to be bootable when the CSM mode of my Bios is not set ?

Regards.

Xuo.

Hi everybody, I have been trying boot Cr OS Linux (ChromeOS)  but sadly without luck.
If any of you knows if there is something to make this boot possible... I left a link for easy access

Hopefully someone will be able to help!!!

Hello!
I've faced a problem booting windows 10 ISO. After selecting appropriate menu entry i see black screen with underscore and after couple of seconds it gets me back to previous menu.
As far as I can see, last entries on logs are "no mapping". It tries couple of times and exit.
bonus question: is there a built-in option in ventoy for logging rather than editing boot entries manually?
Any help would be much appreciated.
