Windows 7: Windows 7: Lost disc space; unable to boot OS?

Windows 7: Lost disc space; unable to boot OS?

Alright.. I have two computers that I'm dealing with here. The first is my laptop, which is obviously running fine. Recently when I was doing a system cleanup, I defragged, cleaned the registry, uninstalled unwanted programs and such.. I do this at least once a month; I'm quite compulsive about keeping my PC running at decent speed.

I went to compare my new disk space to the previous and noticed I have 65 GB free of 144 GB; the problem is that my drive is supposed to be a 218 gigabyte drive. I checked in the partition managing and the disk was reported to have 218, but "Computer" shows only 144.

I am also unable to create a System Repair Disk. The error I receive is "The Parameter is incorrect (0x80070057)". Any help with these are greatly appreciated.


Now, as for the other computer. It is a desktop PC, about 700 GB disk space. I recently created a partition and new volume, and upon rebooting Windows 7 is no longer booting, instead it seems to be booting under the new drive; which only has compressed data for Ubuntu 12. So all it does is freeze after the BIOS loads, showing a flashing underscore.. I have no Installation Disk, and the BIOS seems to be running quite well; (Also no hint of recovery options there as far as I can tell.)


The laptop I am using is a Compaq Presario CQ57; running Home Premuim.

The desktop is a Dell.. Unsure of the model or what Version of Windows 7 it is running however.

Hello

Let us deal with the issues one by one. Can you post a screenshot of your full screen disk management window ?

To get the disk management window, right click on the computer icon > manage. It will open the computer management window. Click the "disk management" on the left pane. Then upload it Screenshots and Files - Upload and Post in Seven Forums

Here's the screenshot you requested; I didn;t have any need to upload it since I have a program. (If it's okay to use; otherwise I will upload directly)

Rightclick on C drive in Start>Computer to choose Properties, post back a screenshot of your pie chart. Use Snipping Tool in Start Menu, attach file using paper clip in reply box.

Run Disk Check on C with both boxes checked.

Next boot free Partition Wizard bootable CD, post back a camera snap of the drive map and listings. This is more accurate the Disk Mgmt some times.

You may already have system corruption as evidenced by failure to generate Repair CD, and the fact that the two columns in Disk Mgmt actually add up to the size on disk could be further corruption. So run SFC -SCANNOW Command.

On the second computer, Mark Partition Active the Win7 partition or it's 100mb System Reserved partition (preferred if you have it) then run Startup Repair - Run 3 Separate Times

I hate snipping tool; but there you go. I'll try what you suggested as well; but I can't create a repair disk (still/yet) to work with the other PC. Windows 7: Lost disc space; unable to boot OS?-capture-2.png

Use the disk provided in Step 5 of Troubleshooting Windows 7 Failure to Boot
which includes everything possible that can be done to start unbootable Win7.

However GRUB on the same HD can still corrupt Win7 beyond repair.

Using the bootable partition manager, would it be possible to eliminate the problematic partition or (if such case) replace C: as the active partition?

Yes, those are all possible.

To delete partition : How to Delete Partition

To mark a partition as active : How to Set Active/Inactive partition

But We would suggest to post a camera snap of the partition wizard drive map . before doing anything

There should be a 100 MB hidden partition , named system reserved, at the left side of C. It is to be marked as active first, and tried to boot the computer . If it fails, try to Rebuild MBR with partition wizard , and boot it again.

Let us know what happens there.

I'm actually considering doing a clean reinstall of windows; and dedicate a 50 GB Partition to Ubuntu from there. I'm having all sorts of problems with my computer; (RAM is supposed to be 2 GB; but its listed as 1.6; and before that it was 1.7). I have an activated copy of windows 7; So as far as my research has led me, I should be able to use my product key to re-install.

(Please correct me on that if I am wrong; I really don't want to lose an expensive OS like this because I simply don't have the money to replace it)
