You DON'T try to boot from the hard disk. You check and see if it is detected by BIOS. (as SECONDARY drive) If it is, go on booting from your "normal" working hard disk and check if Windows (or Linux) can access the partition or filesystem on the repaired drive. If it does but you see "garbled" data, you may need to use a data recovery utility to check it's integrity, like TESTDISK: http://www.cgsecurity.org/wiki/TestDisk If it doesn't, it means that the fix wasn't applied properly, simply did not work, or the drive suffers from ANOTHER problem (not the BSY, not the LBA0), and in any case you should try again to fix it.
