This is a two part question, depending on the answer. I am running a dual boot system, to boot into Win2K OR WinXP. Installing some Kodak product led to a crash and I haven't been able to boot into Windows 2000 since - BUT, I have been working without problem in Windows XP and it's vital that I don't damage or alter that installation. The only message is that the "System" (no extension in that filename) file in System32 is damaged. Because of SP upgrades to Win2K and isolated updates from the web, I cannot use the Windows 2000 CD repair options, without overwriting all changed files - my fear of which will be clear in the second half of the question. So my questions are as follows:
1) Is there anything I can do to repair or replace that "System" file from outside the Win2k environment (in this case, after booting into WinXP) that will enable me to start up Windows 2000, and then apply SP 4 and stabilize my Win2k environment?
If it's necessary to use the CD to overwrite all files, my problem is that I don't want to change the boot system - if win2K is installed AFTER winXP, one cannot boot into WinXP. But I believe there are some root files that can be stashed away elsewhere and then subsequently used to overwrite the files that Win2K puts in the root for the dual boot menu. If there is more to that process, I'm unfamiliar with it, plus I don't know which files are involved, thus:
2) What root level files must I protect - secure copies elsewhere temporarily - and/or any other files such that subsequent to effectively re-installing Win2K (by overwriting most OS files) I will be able to restore the dual boot properly such that I can boot into either OS?
