So Finally Thanks For the Help , I solved the partition problem by using Partition Wizard.
So, Here s the brief story.
Partition wizard wasnt burning on the disk,so no boot time partitioning or conversion from primary to logical.
So,tried to carry out partitioning without boot, just installed partitionwizard , Modified the primary partition C to Logical BUzzzz..(Got message, the system may fail to boot).. Went ON...
so.. What i got was.. A logical C drive without any damage or boot problems...
Yupieee....
Once again ..Thanks to all the members here...
Ya.. if u r gna try this at risk..please create recovery disk first,i repeat, create recovery disk first..
Den Just njoy..
