Big Time Trouble with Windows root

[phate132]

When i boot the windows installed on C:/ my PC tries to get the files
from E:/! How can i change the windows root/the path windows uses to boot?

here's the exact thing: A few days ago i decided to reinstall windows
on drive D. i already had an installation there just for playing games,
and the windows used for work was on drive C. So, i choose to setup
the new Windows at the same location on D as the previous installation
(i didnt mind everything deleting). During the 1st part of installation
(the one not in graphical environment) i get messages4files not able
to be read from the disc. Once everything's over (the new installation
on D works fine) i find out that windows on C wont boot because of files
missing!After a while i discover that restoring the files at C:/WINDOWS
doesnt do a thing, but if i restored the file at E:/WINDOWS -a path that
did not exist at first, as there wan no OS on E (C&E is the
same HD, split in two) does the trick! So, i copy everything from
D:/WINDOWS on C:/WINDOWS (i know its not very smart) and there's no message
telling there are files missing. However, when i boot windows on C the
blue screen with the windows logo appears, and it does not get to the
point where i connect to my user account. SO, my problem is that the
windows installed on C boots from E! Can i change that without having
to install a new OS from the beginning?

Probably not.
