Most of us have heard of UBCD4Win which gives you a Windows like interface on a boot CD. In fact, I have used it in a few of my tutorials here on Technibble. UBCD4Win is great but what if you need to do some more low level work such as testing the RAM, doing a low level format or testing the condition of a hard drive? This is Where Ultimate Boot CD (dos version) comes in.
UBCD assembles over 100 PC hardware diagnosis tools into one bootable CD. It boots up very quickly (about 2 seconds on my machine) and provides a menu to many DOS based diagnostic tools tools such as:
- CPU Tests
- Memory Tests
- Peripherals Tools
- CPU Information
- System Information
- Benchmark Tools
- BIOS Tools
- Hard Disk Installation Tools
- Hard Disk Diagnostic Tools
- Hard Disk Device Management Tools
- Hard Disk Wiping Tools
- Hard Disk Cloning Tools
- Hard Disk Low-Level Editing Tools
- Partition Tools
- Boot Managers
- File Tools
- NTFS Tools
- Antivirus/Malware Tools
- Network Tools
- DOS Boot Disks
- Linux Boot Disks
A full list of the applications it contains can be found here. This application makes a great partner for UBCD4Win and is a must in any technicians kit.

Last time I used this it was a bit lacking in the hard drive diagnosis department but it looks like they fixed that now.
We use this all of the time, and it has saved us a ton of time.
The website states that there is an option for creating it on a USB stick. That would be GREAT. Anyone tried it yet?
I was also wondering about the usb option. Im going to download it and see what happens. Thanks Bryce
Use it all the time also
USB option can be a bit of a pain… but a feeling of triumph when successful! Some bios can boot from a usb now but not all of ‘em.
Another thumbs up. I use it all the time.
