Sorry, I am kind of new to this. I am interested in learning about Linux, but I am hesitant to use Linux as my exclusive OS until I gain more understanding of it.

Some Info:
I have an installation disk for RedHat Linux 9.0.
My current OS is Windows (Windows XP SP3)
I installed VirtualBox
I want to install RedHat as a guest OS on VirtualBox.

Dilemma:
I am able to run the installation, but when I get to the Disk Partitioning Setup....it always fails. No matter what I choose. I get the following message:

Warning:
The Partition Table on device hde was unreadable.
To create new partitions it must be initialized,
causing a loss of ALL data on drive.
Would you like to initialize this drive?

No matter what I choose, it says that there was an error.

I am sorry I am not as computer savvy as many. I am kind of a newbie in all aspects.
If anybody could help, it would be greatly appreciated!

If you can kindly explain it in easy terms? I am so new to this and I don't even know what mounting and unmounting is.
