I have now read your PM. YOU HAVE NOT WASTED MY TIME. We are all volunters, here because we enjoy helping with your computer problem. The dificulty here is HOW long this is going to take with you having to relay by telephone each instruction to your sister and then her message back to the forum.
Unfortunately, this will not be a simple matter of you relaying the instructions, unless you wish to proceed with the Recovery, IF that HP computer still has the original recovery partition.
When your sister gets to Safe Mode, she needs to click START, click My Computer, then hold the mouse on C drive, what is the size of the HDD and how much free space.
Really I could do with knowing that.
Then while in Safe Mode, click start, click run and type in "cmd".
A window will open.
Whatever is displayed after the C:\ prompt type in "CD\"
Then type in "chkdsk"
It will tell you that chkdsk is running in read only mode.
Pls post back what it says.
Any bad sectors and the rest of the details.
All commands are typed without the colons.
