A must have Ultimate Boot CD on USB drive.

This compilation of software has just about everything you need to diagnose hard to find low level problems, and also some other tools that every PC technician should have available.

Some great things I’ve used the UBCD to do:

• Fixing a system whose boot loader did not install correctly
• Use it to wipe a system before recycling it
• Fixed a tricky system freezing problem that was caused by a bad stick of RAM
• Run OEM HD tools to confirm a hard drive was indeed malfunctioning

The directions on how to do this are courtesy of pendrivelinux:

1. Download the Ultimate Boot CD iso file and place it into its own directory
2. Download the UBCDfix.exe file and run it, extracting into the above folder
3. From this folder click fixubcd.bat and follow the instructions
4. Move the contents of the /dir/USBUBCD folder to your USB drive
5. From your USB drive, run makeboot.bat to make it bootable

That’s it! You now have a bootable USB drive.
