Hi ilko_t, The BSOD stop code i got while installing Win XP pro x86 SP3 NL: 0x0000007B (0xF7916524, 0xC0000034,0x00000000,0x00000000) Thanks! Try the modified ntdetect.com:http://www.msfn.org/board/faqs-t116766.html You'd need to replace the one in the corresponding ISO file in WINSETUP directory, and just in case the one in I386 directory. It worked! Thanks A LOT! Can i use the modified WIN XP iso image to burn a install cd? Or can the modified NTDETECT.COM only work on USB-sticks? Thanks!
