Hi - My friend has a Dell Dimension 3100 with XP. He got some nasty malware, etc. so he wanted spybot to fix the hundreds of issues it found. On restart, there was the ntdlr is missing message, and nothing seemed to work to replace the files, Windows Recovery, etc didn't seem to work to replace it on the C: partition. I backed up everything on C: partition and I installed XP on the backup partition D: and reinstalled the programs he uses on the D: partition so he could still do what he needed to run his business. I still need to run XP from old C: partition now and then to run programs to create backup files, etc. that I can't do from the D: partition. I have heard it can be risky to change the boot partition to C: because I'm not even sure if it will boot properly and I could really be stuck. It would be nice if there were a list of partitions on startup I could boot from in case C: is too corrupted or whatever to work. Any suggestions?
