Windows 7: Installation Drive

02 Jul 2010   #1

Windows 7
Installation Drive

I have vista installed on C drive, which is the primary drive, and windows 7 on X drive, which is a logical drive. On startup I am given two options of whether to login to the C or X drives. Now I have windows 7 installation files on X drive and I want to install windows 7 on C drive -- I am doing this because cd-rom on this laptop doesn't work. Would it be able to install or would it face problems? I have tried launching the installation file and it seems to accept C drive as the installation drive, but would it go through with it to the end or not? Any ideas?

Windows 7

I actually had the installation file on X drive partition and ran it from there.. it apparently copied the files to some mysterious place and installed on C drive just fine. It apparently deleted the vista and installed windows 7 on it. Works fine.. you can add this method to the list,, only if the installation file is on the drive I suppose or maybe not.
