Can't access my C drive

[Lforte]

When I right click on my drive and click general it shows the drive to be full and under file system it shoes nothing should it not show NTFS? I can't access the drive in any way and shows full

 

[Lforte]

I can't even perform a disk check because Windows can't access the disk

I tried to edit users in the registry because I as having problems running as administrator.....so I may have changed something there related to users

At this point, a reinstall of the OS is probably the best way forward.

I just checked disk for fragmentation and it tells me it's 34% fragmented....would it help to try and defragment?

 

[Lforte]

I tried to reinstall Windows but it won't let me.....says disk is not NFST

 

[Lforte]

Maybe format the disk?

No, defrag has nothing to do with this.

 

[Lforte]

I can't even create another user account

Maybe format the disk?

In the OS install...
When it asks where, select and Delete ALL partitions, leaving one large space
Let Windows format that, creating what it needs.

Of course, everything on that drive will be gone, so save anything critical if you can.

I tried to repair disk using Win 7 install disk but no luck

 

[Lforte]

My most critical files are backed up on external drive but there are other files I didn't want to lose but can't back ip now because I can't access the disk........so when it ask where to install the OS I have to first delete all partitions showing?

I fear it is too far gone for a simple 'Repair'
Full reinstall.

Correct.

I was thinking thhat the reevistry could ne edited to allow access to the C drive but I don't know how

 

[Lforte]

What about trying to format the disk?

 

[Lforte]

Should I disconnect any external drives when trying the reinstall?

 

[USAFRet]

Should I disconnect any external drives when trying the reinstall?

Yes. Disconnect ALL drives except the specific drive you want the OS on.

Every guide that talks about editing the Registry has a warning:
---------------------
Warning
• Incorrectly editing the registry may severely damage your system. At the very least, you should back up any valued data on the computer before making changes to the registry.
---------------------

As you have found.

 

[Lforte]

OK. I will try the full reinstall and see if it works

 

[Lforte]

[USAFRet]

Too bad he didn't make a backup of the registry at least.
