Not enough disk space to upgrade install windows 7?

i have windows 7 home premium sp1 installed on my system with all the updates.however ,over time,some files have got corrupted so i have decided to do an in place upgrade which will repair the system files.
i have a dvd disc that is also windows 7 home premium sp1 dvd
many people have the same problem as me
but none of the answers in the forums seems to solve anybodys problem because it works for none of them or else there would have been atleast one positive reply,i have yet to see one.
its the same answer over and over again given by the professionals which actually doesent work.
im tryin to upgrade install windows 7 because i have some corrupted windows 7 system files
i can howveer boot into windows without problems
but the real problem is once i start the upgrade
and when i about to near the end,i get error message "not enougn disk space to install windows,try freeing up space and restart installtion"
actually i have 210gb remaining free space
on C.
isnt that more than enough space?
i have tried the following which were suggested on forums which didnt work.
1.i have set the service "virtual disk" to automatic and rebooted and still same problem.
i have also defragmented and checked the disc for errors.
nothing works

Hello Allan, and welcome to Seven Forums.

Since this was for corrupted files, you might see if downloading and running the 64-bit (x64) System Update Readiness Tool for your same installed 64-bit Windows 7, restart the PC afterwards, and try the sfc /scannow command again may help to fix any corrupted system files.

If that doesn't help, then I would recommend a clean install instead for the best results.

Hope this helps,
Shawn

Why don`t you back up your files and do a clean install, it`s the only way to fix it right. You have the Home Premium license key, so why not.

Do you have the default 100 MB System Reserved partition?

If so, did you or any ASUS program save anything to this partition? For example, restore points being saved to it. If so, then that's the partition that is low on space for this reason.

How to know if i have have 100mb free system reserved partition? I have an Asus laptop which i also think is an OEM version. I also found out that disk c is the active partition and has 500gb space out of.which 21gb of it is used as recovery partition with windows 7 factory state reinstall.both the recovery partition and c is marked as active and disk d is marked as logical.now shouldn't windows 7 in place upgrade or reinstall be straight forward? Cox if these issues wud be affecting windows install then Microsoft should have made it easier for people to install.basic common sense wud be to install windows 7 on c and any person wud make free space on c, so if we free up space on c there shudnt be further problems.if u have any solution then please do let me know

Check using the tutorial below to make sure that you only have system protection turned on (checked) for your C: drive. Uncheck any other listed drive if checked.

Yep, turn system protection off for all drives but C, then try doing a repair install again to see if it may have been the issue.

Before doing a repair install, I know you said you did a SFC scan, but did you do what I posted above to try and repair the component store to see if that will allow SFC to fix your corrupted files without having to do a repair install?
