how can I restore deleted boot files of my HDD?

Few weeks back I tried turning on my old PC as I wanted to use it as a spare Television. After turning it on, I realized it was having blue screen problem, so I tried re-installing windows XP but installing in previous windows XP drive(C) failed as a result I installed windows in F drive.

After successful installation I booted my new windows from dual boot and started wiping data from C drive, at first I tried formatting C drive which failed then I started deleting individual files from C drive. During wiping I turned on visibility of system and hidden files and wiped everything from C drive (Including any files used for booting in C drive). Then after some minutes I restarted my windows.

From that moment on whenever I try to boot my windows it shows the following error:

"Boot failed: system halted"

After that I tried reinstalling windows XP via same USB boot stick but boot screen gets stuck at message:

press any key to boot from cd . . . (or something like that)

I also tried accessing my IDE HDD by inserting it as a slave in master slave formation in another PC; when I tried opening old HDD most of the drive won't open except one drive which opens but after several minutes of opening it and most of the times it either doesn't responds or responds too slowly.

How can I make this HDD to successfully boot up? Is there anyway I can restore those boot files?
