Veja a resposta abaixo encontrada em este site :
Windows 8 is designed to close and reopen by faster booting (Hybrid Boot), it has left your system in a hibernated state, with the drives mounted, open and ready to take off as soon as Windows 8 restarts. When a drive is mounted, a little piece of data is written to a standard place on the disk to show it is in use - it is called the "dirty bit".
This means that the "dirty bit" on the disks that Windows 7 checks on startup is showing on the disks. And then, chkdsk is automatically run to check the integrity of the disks with the "dirty bit" set. Please check the following settings. (In Windows 8, 8.1 and maybe 10)
- Control Panel -> Power Plan
- Select "Choose what the power button does" on left hand side.
- Click on "Change settings that are currently unavailable".
- Uncheck "Turn on fast startup" under shutdown settings.
