I've been trying to install First Defense-ISR Rescue on this computer and it won't install, it gets a -11 code and quits. The code means This means the boot sector is not a standard Windows boot sector. I have Windows Vista Home Premium 64 bit. My question is, if I remove the Recovery Partition D will this change the boot sector. I have factory backup DVD's and made my own DVD's, plus I have a TI image of the drive so I'm OK in that department.
