I can imagine someone saying Windows what!!! This is an oldmachine my son uses for surfing the net. I was trying to clean out a lot of junk etc and decided to reinstall windows. I deleted through dos at C:\deltree windows. When I restarted the computer I get two messages of files missing or corrupt, 1. C:\ windows\ifshlp.sys 2. C:\windows\system\vmm32.vxd. I have a startup disk for ME but when I get to an A:\ prompt I can get to other drives but my cd-rom drive won't read so I cannot get any further. I notice in another posting Howard has asked about reformatting his drive. Can I follow these instruction or does someone else have other solutions other than throwing the machine out and starting with a new computer. Thanks wil.
