Hi guys. A few day ago, when I tried to started my laptop (hp probook 4534s), i got disk check. After that when I try to download something i get this error ("The disk structure is corrupted and unreadable") and I cant download it.
And when i try to install mozilla firefox i get new 7-zip error ("can not create temp folder archive")... Please somebody help me

Perhaps the disk check was just a simple scan, or was interupted.

Run a Full scan with Repair:

• Start > All Programs > Accessories
• Right click on Command Prompt > choose Run As Administrator
• Type: chkdsk /r and then hit enter (This is providing there is only one disk and it is the one with the OS on it)
• You will get a warning and you will be asked to run diskcheck at the next startup > say yes.
• Restart the computer
• Do not interrupt the process.
