Multi-Tool USB (Medicat Suite)

A project focused on transforming a USB into a bootable repair stick: Medicat as the base, extra live ISOs in one folder, PortableApps for day-to-day tools. v21.12, Ventoy does the booting.

Where new stuff goes: drop extra .iso files in Live_Operating_Systems. Don’t unzip them. Ventoy lists whatever is in that folder.

How to Use it

PortableApps

If you booted Medicat → Mini Windows 10

1. Wait until Mini Windows 10 finishes loading.
2. Look at the taskbar on the right, near the clock.
3. Click the grey circle with a white arrow.
4. The PortableApps menu opens.

If you are already in normal Windows

1. Open the Medicat drive (for example D:).
2. Go to PortableApps\PortableApps.com\.
3. Double-click PortableAppsPlatform.exe.
4. The menu pops up and fills in with programs.

Add Clonezilla, Kali, Netboot.xyz, Ubuntu, Debian

An ISO is one file that holds a whole OS. Copy it into Live_Operating_Systems.

Tool	What to download	Notes
Clonezilla	live ISO, e.g. clonezilla-live-3.3.0-33-amd64.iso	Optional. Medicat already has other backup tools.
Kali Linux	live ISO, e.g. kali-linux-2025.4-live-amd64.iso	Use the live build, not the installer.
Netboot.xyz	netboot.xyz.iso	Needs LAN files or internet so it can fetch tools.
Debian	netinst ISO, e.g. debian-13.6.0-amd64-netinst.iso	Same drop-in folder. This one installed as Debian 13 (trixie) 13.6.

Running the multi-tool USB to install Debian 13.

An SSH session in the new Debian installation.

Boot an ISO from Medicat

1. Restart the computer from the Medicat USB, not from Windows.
2. Arrow down to Live Operating Systems and press Enter.
3. Every ISO you put in that folder should be listed.
4. Highlight the one you want and press Enter.

After that, follow the on-screen installer or live-session steps for that OS.
