I think you need to resolve your chkdsk issue. I would do it like so:
- Keep tapping F8 during the early boot phase.
- Select Repair from the menu that looks like this one.
- Log on as Administrator if prompted.
- Select Repair when prompted.
- Select the Command Prompt from the menu that looks like this one.
- Identify the correct drive letter for your Windows installation. It could be a drive other than C: but it won't be X:. You do it by typing the commands
dir C:\Win*
dir D:\Win*
dir E:\Win*
until you find the Windows folder.
I will call that drive "Q:".
- Type this command and press Enter:
chkdsk Q: /R
