I was only trying to integrate drivers for my AMD64. After all the iso image is created but the image/cd wont boot. It says "NTLDR is corrupt. Restart ....." Next i tried to simply insert the newly created files and folders to the iso image of the original cd with UltraIso and burn the image, again the same error. I extracted the boot image from the original cd but it comes to the same error. I am using nLite 101 and UltraIso 8.2 Nero 7.2.7.0 with HP 735d writer on AMD64 K8-V machine with 1GB RAM and nVidia FX5200 AGP.java script:emoticon('', 'smid_6') What can be the mistake done by me? regards
