I had installed Red Hat Linux 8.0 on my system with 2 partitions..

I installed the Linux by choosing the Option of paritioning of hard-disk on the Installer's behalf.. !..and Also My installation was with GNOM..not text based.

The Red Hat Linux 8.0 got installed sucessfully, and I was happy to install the Linux for the first time.. I Logged in successfully, used some programmes..and..What happened that A programe got stucked..and I had no option to forcefully restart the system by hitting the Restart button..

But when the system restarted and It displayed the graphical screen which appears just before the Login screen.. the System got stucked there in a way that it.. flicks the screen after few secs but was unable to proceed...

After I waited for some time it showed me a message telling me about the failure..of Loading

So.. How will I be able to overcome this Problem...?
Pluse..give a hint to save my data as well on the D Partition of the hd..as linux didn't touched that and left that the same..?

And please also let me know how could I recover the partition .. occupied by the Linux.. using FDisk utitliy..? of Windows..? or Is there any way to format the first partition to vfat using any of Red Hat Linux 8.0's utility.

As well as Please let me know how could I install both Linux and windows.. at the same system.. ?

Can you help Me?

Thanks..in Advance..
