Shut down, System Restore, Reboot Issue

Please open Command Prompt as a administrator and type following command:

Code:

Chkdsk C: /r

You will be prompted to schedule a error checking type Y and press Enter key. Reboot your computer.

I have tried SFC, Chkdsk, bootrec and none of them work especially if they require a reboot. I am pretty convinced the issue is the rebuildbcd command error is at the root of the problem, I just don't know the command(s) to repair that error.

Type the following commands at the Windows RE command prompt:

• c:
• bcdedit /export C:\BCD_Backup
• cd boot
• attrib bcd -s -h -r
• ren c:\boot\bcd bcd.old
• bootrec /RebuildBcd

Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

Thanks to both of you. I will try both of these this evening. I found this in the SrtTrail.txt log file. Boot critical file C:\WINDOWS\System32\drivers\ACPI.sys is corrupt. Any ideas on this?

If you can boot into Windows OS open the command prompt as administrator and execute following command.

Code:

Sfc /Scannow

This command tool will try to repair any corrupted system files.


If you cannot boot into Windows OS boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below command into Command Prompt and press Enter key.

The following command scans integrity of all protected Windows system files and repairs files with problems when possible.

Code:

Sfc  /Scannow   /OFFBOOTDIR=D:\   /OFFWINDIR=D:\Windows

Please replace partition letter D: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

@FreeBooter do you have some good sources to learn the commands?

If the partition is on D how would you change these commands?

• c:
• bcdedit /export C:\BCD_Backup
• cd boot
• attrib bcd -s -h -r
• ren c:\boot\bcd bcd.old
• bootrec /RebuildBcd

which c remain the same and which c are changed to d?

What happens if the sequence does not have cd boot and has this sequence:

bootrec /fixmbr
bootrec /fixboot
bcdedit /export c:\bcdbackup
attrib c:\boot\bcd -h -r -s
ren c:\boot\bcd bcd.old
bootrec /rebuildbcd
y

If the operating system were windows 7 instead of windows 10 would anything change?
On windows 7 are there separate partitions for boot and system? If so how would the above commands change?

zbook, you will need to determine which partition that windows is installed on you can experiment by typing cd c: then type dir if windows isn't there then change to cd d: then type dir. Whichever drive windows is on, you will need to change to that drive and use that letter in the commands.

It has been awhile since I used DOS commands you may just need to type c:\ or d:\ with no cd

If rebuildbcd displays:

Scanning all disks for windows installations.
Please wait...
Successfully scanned Windows Installations.
Total identified Windows Installations: 0
The operation competed successfully.

What would be the interpretation and the next step?
