If you want chkdsk to attempt to repair logical file system errors during the scan, add the /f switch. Note that if the drive has files that are in use (and it probably will), you’ll be asked to schedule a scan for the next restart. You won’t get any kind of feedback that the scan has been cancelled, but it will have been. This command actually excludes the drive from the chkdsk command for the next start. If you do restart to find that a scan has been scheduled, Windows is also kind enough to provide you with about ten seconds to skip the scan if you want to.

Step 3: Rebuild Boot Files

Choose your Windows version (XP, Vista, 7 or 8) before downloading. The System Wikidll Recovery Options screen can also have manufacturer-specific tools that can help you recover or restore your computer. Startup Repair automatically scans your hard disk for errors and tries to fix the errors. Go to the Start Menu, type msconfig in the search box, and press Enter. The first configuration works best for older systems where the BIOS is unable to boot from partitions that aren’t FAT formatted.

UEFI is a new boot mode and it is usually used on the 64bit systems later than Windows 7; Legacy is a traditional boot mode, which supports 32bit and 64bit systems. Legacy + UEFI boot mode can take care of the two boot modes. If you choose to delete a version from the Boot tab of msconfig, that Windows version won’t be deleted, but it won’t be displayed on the Windows Boot Manager screen. Using the msconfig utility tool allows you to select which version of Windows you’d like to boot directly into when you restart your computer.

The second configuration works on most modern computers since they’re able to boot directly from an NTFS formatted partition. Do you need to enable UEFI to run Windows 10? You don’t need to enable UEFI to run Windows 10. It is entirely compatible with both BIOS and UEFI However, it’s the storage device that might require UEFI.

ScanOs will also print installations that are not currently in the BCD. bootrec /FixBoot will write a new boot sector to the system partition.

If your system is Windows 7, FixBoot will write a Windows 7-compatible boot sector and so on. Press Shift and F8 quicklyShift + F8 doesn’t always work, as reported by some users. If this is the case for your system, consider using Easy Recovery Essentials to run Command Prompt – details below this section of steps.

If Windows has scheduled an automatic check of the drive, you’ll see a message letting you know that the volume is dirty, which just means it’s been flagged with potential errors. This serves as indication that Windows will run a check the next time it starts. If no automatic scan is scheduled, you’ll just see a message letting you know that the volume is not dirty. If you elect to fix file system errors or scan for bad sectors, Windows won’t be able to perform a scan while the disk is in use. If that happens, you’ll have the option to cancel the scan or schedule a disk check to happen the next time you restart Windows.
