Hi all, Have a problem with a machine running XP Pro SP1. A guy installed a 3G modem, rebooted, and started getting the NTLDR missing msg. I tried running Recovery Console, fixboot, fixmbr, manual copy of NTLDR and NTDETECT.COM etc, my question is... Would the fact that I'm using a SP2 disc to run recovery console mean that the NTLDR and NTDETECT.COM files I'm copying over are incompatible? The only way I know the machine is XP PRO SP1, is that when I booted with ERD to see if I could access files, it could not attach to the OS and it was unsupported. Any help would be greatly appreciated, I would do a format and manually backup/restore files, but there is software running on the PC which the user does not have CD's for. Thanks. Bosey

You can try these. How to fix: NTLDR is missing, press any key to restart. http://tinyempire.com/notes/ntldris... Or, it may be easier this way. Avira AntiVir Rescue System http://www.softpedia.com/get/Antivi... http://www.softpedia.com/progScreen... http://www.free-av.de/en/tools/12/a...

Nice link there cheers. Skeptical of these ISO boot fixes, as I've got burnt before. What exactly does it do?? From what i can gather it replaces system files and write a new bootsector, which I've done already. i'll give it a shot tho as I'm at my wits end. Will post results. Bosey
