Clean Win7 reinstallation use up all disk space on drive C

February 17, 2012 at 07:20:32
Specs: Windows 7, 4G
Just re-installed a PC with a 500G HD, but it shows to be almst full.

I had the same problem with a laptop that I re-installed Windows 7.

I must be doing something wrong when I did the Clean Reinstall.

Did I reinstall onto the wrong partition? I only have 1 drive, the C Drive.
Should I have created a new drive to install the operating system on to?

Can anyone let me know how to fix this.

The machine works fine, except for this.

Many thanks

"I must be doing something wrong when I did the Clean Reinstall"

Define "clean reinstall". Did you completely wipe the HDD of all partitioning & create a new partition (or partitions)? How big is the C: partition? Did you use a retail copy of Win7 or the Dell recovery disk?

Hello

Thanks for your help.

I realise now that I didn't do a format, for some reason the Win7 installation disk didn't ask me if I wanted to format, and just re-installed the OS.

Of course, it saved all the old files, so that's why the C's full.

Next time I'll have to make sure its formatted...


thanks

For a completely clean install, choose Custom then Partition/Format. Delete the existing partition, create a new partition, and format it. Then the install will be completely clean with no "old windows" folder or anything else left over.

You have to be a little bit crazy to keep you from going insane.

Thanks - where should I install the new Windows after format - never sure. Do I create a new partition, or put it in C?


Thanks

If you delete all of your current partitions, there is no C anymore, you will have to create a new partition out of the unallocated space. This partition can be set to all of the drive (Windows will set aside a small amount for a boot partition), or you can just create enough for Windows and your programs (100GB to 150GB) and later (in Disk Manager) you can create a second partition for your files. This has the advantage that if you ever need to reinstall Windows again, your files will be on their own partition and will not need to be put back (backed up anyway of course). These partitions will need to be formatted after they are created so that Windows can use them. Windows will always designate the partition it is installed on as C drive and you can always add labels to your partitions like 'System Drive' and 'Storage Drive' if you will find that easier to keep track of. On systems with more than two partitions and/or physical hard drives, this usually becomes essential.
