Thanks_Sami_Firefox_need more help please?

Thanks very much Sami and firefox, i fixed the problem with the laptop, really it was successful guys...
I got another one now!!
Its HP Compaq desk top, i wanted to partition the HDD but didn't know to use the System recovery function in windows itself, i formatted the HDD and partitioned into two partition, but the bit with the recovery data still there.
Now how could i use the partition that hold the recovery data meanwhile i installed another version of windows of xp(as far as i have my original windows so why shouldn't i reinstall it again??
could you please guide me with a good solution to my desk top thankfully..
