MediCat 19.10

Until version 19.10, MediCat was available in a version called « Medicat with Mini Windows 10 ».

MediCat 19.10 was a Windows 10-based « Live » operating system on which portable troubleshooting applications (PortableApps) were installed.

The size of « MediCat with Mini Windows 10 » was only 7,14 Go which allowed it to be installed on most USB keys on the market.

MediCat 19.10 is no longer available for download, but your servant makes it available on this page:

Medicat 20.xx

In version 20, MediCat has been deeply overhauled and is now based on Ventoy, a utility that allows you to run ISO images directly without extraction.

No more portable applications, MediCat is now Ventoy + ISO images containing troubleshooting tools.

MediCat 20 is much more flexible and customizable: you can add, modify and delete ISO of the software that interests you.

The downside is its size: about 22 Go !

A USB key of at least 32 GB is therefore necessary in order to install MediCat. If you do not have one, I recommend the SanDisk Ultra USB key which is efficient and offered at a low price.

To create a USB key with MediCat 20, you will need:

  • Have a USB key of at least 32 GB
  • Download MediCat via Google Drive, MEGA or BitTorrent (recommended)
  • Use the imageUSB software to write the medicat.img file on the USB key and create the MediCat USB key
