so I created a custom wim file of win 10 and syspreped it. I would like to try it with a answer file without image manger  ...... but how?

Is it possible to modify a CSM (legacy) bootable iso to a UEFI or CSM and UEFI bootable ISO for use with Ventoy?

If yes where can i find detailed instructions for the same?

Many Thanks

Prior to finding your tool I discovered this tutorial on how to make a recovery USB for Windows 7 and it worked flawlessly. I would like to use the same method in Ventoy in order to have both the Windows 7 Recovery environment and my other ISOs on the same USB flash drive. However I don't seem to find a way to do it.

• The created ISO appears as unbootable and doesn't start at all
  
• I tried creating a folder and pasting the original files there, then use the wimboot plugin, but while it did find boot.wim, Windows told me that it was unable to load any system file (although on my other USB everything went fine).
  

如题，没看到有更新选项阿？是有安装选项！从2020.9月起，WINDOWS板就从来没成功安装或更新过。

First of all, I'd like to thank all people involved with this project/forum for your hard work and dedication. I'm new user, made a USB stick in Linux with Windows 8.1 and MX Linux ISO, no problem preparing the USB, but when I tried to run it, Linux ran OK, but Windows gave me an error: 

EdIT
FORGET everything, I was thinking it was harder to change than it was. It's a really simple yet using the guid as part of it cleverly confusing.

Value ? Value : "",plate, guidstr, #the primary line


If I go to big with the array size ( added about 7 bytes  is that  whats braking the booting of the ISOs? OR Compile-assert was complaining  so I altered that I will put that back to a -1 ,


I know I figured out how to change the data in the guid yet adding a few characters has crashed the program.   
UPDATE :
I figuring it out. This is a really fun puzzle I Made it harder, it was simple.
Its all about being able to remove the www.ventoy.net and other texted. Or changing it. Nice Puzzle!
Its not hard to find lol.

I was trying to change the GUID because that contains the web link , why didn't I realize that was going to cause trouble, thats limited to 16 bytes.



THANKS 

Haven't yet fully tested this and I had to make a quite a few changes to the build scripts to get everything to compiled,
So far it's working well. 



 I wounder if the -m32 and -stactic options will cause issues for the 32 bit versions?   

I will post a how to once I verify all the steps.

I Love open source.

dear sir Longpanda you have created a real masterpieces in multiboot.
just a request maybe for future:
do you have considered to add the ability to browse other disks internal or usb attached so we can boot others isos or vhd that are not on Ventoy partition?
For the moment i use inside your Ventoy  a grubfm_multiarch 740.iso that has this feature, it works but is not so good as booting directly the same isos or vhd from Ventoy (more slower and less compatibility). I know that Ventoy is slow browsing a complex directory cause it read and determines all files types for show only bootable files,(for this you have added the triks of .ventoyignore) but maybe you can add also the choice to show all files without analyze them.
in  every case thankyou very much for your beautiful creation

Hi, I have a request for the current disk layout when installing Ventoy. 
Is it possible to add an option to select an arbitrary initial part of LBA PART 1 when writing Ventoy to leave unallocated space with bad sectors at the beginning of the external hard drive?
Or the sector ranges option (start LBA — end LBA) to select an undamaged location in the middle of the hard drive? 

Illustration of the idea:

Sorry for my English translation.
Thanks.

Please add support for Arcabit - Rescue Disk iso. It uses Tiny Core Linux, but it doesn't load in Ventoy even in BIOS mode. It stops at the Linux console.
