It has already been written that to access the Medicat.img files it must be mounted with OSFMount. Also 7zip allows to extract the files from the .img

@joaopais you need to do two simple steps:

1 - check hash of Medicat.img file
2 - run ImageUSB and write Medicat.img file to your USB stick, no need to mount or extract anything

Finally built 20.08 on 32G USB drive and works fine.
Notice it used 25.55GB (as primary partition-Ventoy), 32MB (VtoyEFI), and unallocated space of 3.31GB.
This make the primary partition left with no space for additional program or ISO file.

Could I use some kind of disk manager program to relocate the EFI partition so I can expand the primary partition ?

@Chansm
you need MiniTool Partition Wizard Enterprise (it's in Portable Apps folder) to move EFI partition on the right end, then expand Medicat partition

Thanks, did it. My guess is my 32GB USB drive has slightly larger capacity vs the original one created by the image utility.

Hi @Jayro,
First, thanks for your fantastic job !
But, as far the Microsoft "Surface Laptop 3" with AMD Ryzen 5 is concerned :
- When a prog of your suite is chosen and is running well, generally the mouse, the keyboard and the touchpad aren't active, and there is no possibility to use the prog.
- Among the exceptions, with Active Boot Disk mini OS the mouse answers but not the keyboard nor the touchapad.

Is there a way to inject the drivers of my laptop ?

Have a good day,
-Valp

Hi,
I created a 20.07 usb stick, moved the ventoy partition to the end (minus 1 MB), I extended the first partition (I forgot to leave 1 MB), I pushed the 20.08 update files to the stick as described in the readme, I was able to boot (after deactivating secure boot on the laptop) the key successfully (and it is very nice).

I tried SpinRite and it gave me :
No bootfile found for UEFI!
Maybe the image does not support X64 UEFI!
I am actually using SpinRite from a 20.07 key on an older computer successfully... Strange, Ventoy update ?

Thanks again for your work

you can add them in the '\System\Drivers\' folder (it's the partition with all the iso and portable apps)

Disable secure boot in your bios first.

You've got to boot into BIOS mode, and use MEMDISK. (That's why I put the [BIOS+MEMDISK] tags next to the ISO, so you know what boot modes are needed to make it boot right)
