Please provide more information. With the information provided it is impossible to figure out what is your problem.
What distribution are you using.
What is your 'other' OS in your dual boot.
You 'tried' to install it before: Was it working then? Did you have the same problem? another problem?
What are the symptoms? (You left that paragraph blank)
Provide a transcript of the system log if available.
Without knowing anything else here is a general recommendation:
Try using a CD Bootable distribution. That will help you narrow the problem and identify if it is a problem with your computer, with the installation or with the distribution. I would recommend Knoppix. It has a very nice partition manager. Or Linux Puppy: it has a very small footprint.
After you make sure that your computer works with the CD bootable distribution do the following:
1. Remove all linux partitions,
2. Fix the MBR (if your primary OS is windows here is how http://www.linuxquestions.org/questions/history/304024
3. Reinstall from scratch using a stable distribution.
If this does not work, you may need to repeat steps 1 to 3 using different distributions. (Actually as a newbie I tried three different distributions until I found one that did a clean install for my computer)
