MediCat USB stands as a comprehensive, community-maintained bootable troubleshooting environment designed to replace outdated toolkits like Hiren's BootCD. Created by developer Jayro, this collection transforms a standard USB drive into a versatile repair station capable of diagnosing hardware issues, removing stubborn malware, and recovering lost data from unbootable computers. Instead of relying on a single static image, the software utilizes a modern Ventoy-based architecture, allowing you to simply drag and drop multiple ISO files onto the drive and boot them instantly through a user-friendly menu.
Key Features
- Ventoy-Powered Multiboot: Eliminates the need to constantly reformat drives by allowing you to copy ISO, WIM, and IMG files directly to the USB stick, which automatically populates them into the boot menu.
- Mini Windows 10 & 11 PE: Launches a familiar, lightweight live desktop environment that runs entirely from system memory, giving you full access to files and tools even if the host operating system fails to start.
- Malwarebytes & Antivirus Tools: Includes a dedicated suite of security scanners to detect and neutralize viruses, ransomware, and rootkits that might be preventing a standard Windows boot.
- Password Removal Utilities: Features specialized tools like Jayro's Lockpick and Active Password Changer to reset forgotten local account credentials on Windows 10 and Windows 11 systems.
- PortableApps Suite: Pre-loads hundreds of standalone diagnostic utilities, including CPU-Z, CrystalDiskInfo, and Snappy Driver Installer, accessible directly from the live environment without installation.
- Backup & Recovery Solutions: Provides industry-standard imaging tools such as Rescuezilla and Acronis True Image to clone failing hard drives or restore deleted partitions before data is lost forever.
Use Cases
System administrators and IT technicians utilize this toolkit to troubleshoot Blue Screen of Death (BSOD) errors and revive crashed workstations without wiping the hard drive. It also serves home users who need to recover improved family photos or critical documents from a laptop that refuses to load Windows 7, Windows 8, or Windows 10.
By combining flexibility with a massive library of maintenance utilities, MediCat USB offers a reliable, free alternative for anyone needing to perform serious computer repair work.
