Hello I have a boot problem I thought it was the old hard drive so I replaced it with a brand new one and reinstalled the os and everything worked ok that day.

The next day had boot problems again.

File:\Boot\BCD

The boot configuration data for your pc is missing or corrupt.

 

So here is what I have tried so far.

I used the instillation disk and booted into the part at the start with cmd prompt and typed and none of below worked.

 

bootrec /fixmbr

bootrec /fixboot

 

attrib -r -s -h c\:boot\bcd

 

del c:\boot\bcd

 

bcdboot c:\windows

 

bootrec /rebuildbcd

 

Iget one healthy post beep at the start and no hardware seems to be faulty that i can tell.

I ran avast boot scan, tdskiller, mrbscan, malwarebytes/rootkit, rougekiller, emisoft emergancy,  all came up clean.

AVG boot kit came up clean but showed errors in the mbr and agmer scan listed stuff but i don't think any of it is malicous. I will enclude the gmer report and avg boot kit one hopeing it can shine some light.  

I also took the machine apart cleaned it and that hasn't worked.

I have tested the memory all fine.

I really don't know what else it could be but something is killing the mbr at every start of the days boot. Here's the odd thing once I can get into the os it then will restart ok with no problems its when it's left off over night the next day it all goes wrong.

can anyone shed any light at all on what is going on here please.

Kind thanks HolyCowz

I would check SMART health status report of your hard disk drive. If you can connect the hard disk drive to a different computer use CrystalDiskInfo program to view SMART health status report of the hard disk drive.

I checked the drive with the program you said and all reports as good.

Its a brand new hard drive. I probably didn't explain to well. The old hard drive first started to do this and was starting to report as faulty with many corrupt sectors and couldn't be fixed so when it wouldn't boot I thought it was the drive so I got this brand new one which also doesn't boot.

Thanks

What kind of output these below three commands gives?

BOOTREC /FIXMBR

BOOTREC /FIXBOOT

BOOTREC /REBUILDBCD

Can you also execute below commands and see if the hard disk can be detected by Windows and if partitions exist.

Diskpart

List disk

Select disk X

List volume 

Replace X letter with your hard disk assigned disk number.

 

It will be fantastic if you can post screenshot of these commands.

[HolyCowZ]

Bootrec /fixmbr and /fixboot worked but bootrec /rebuildbcd did not and I could not get it to work.

 

One question I do this with the start up disk at boot?

Diskpart

List disk

Select disk X

List volume

 

Thanks FreeBooter 

[FreeBooter]

You need to use your mobile phone to take a screenshot!

 

You need to make sure System Reserved partition is active which is usually around 350 MB size.

 

 

Connect the hard drive to computer and boot your computer with Windows 10 Setup DVD, open the Command Prompt and execute below command.

Dir C:\

Can you tell if output of this command displays "Boot" folder.

[HolyCowZ]

Heres the screen shot

What does volume in drive C has no label mean please. I'm also writing everything in my book so I learn from this.

[FreeBooter]

You can label any partition you don't need to worry about that output its not a error message.

We need to mark the System Reserved partition as active partition please execute below commands and post the screenshot of the commands outputs.

Diskpart

List disk

Select disk X

List volume

List partition

Replace X letter with your hard disk assigned disk number.

[FreeBooter]

Thanks HolyCowZ but you forget to enter List volume command i also need output of this command even do you have 500 MB partition i want to make sure this is system reserve partition before mark it active partition.

[HolyCowZ]

Sorry it was late when I posted I was half asleep.

[FreeBooter]

Let mark the System Reserved Partition active.
 
Please execute below commands:
 
 
 

Diskpart 

List Disk 

Select disk X

List partition

Select partition 1

Active

Exit

Bootrec /rebuildbcd

 
 
 
 
The 500 MB is the System Reserved partition, please make sure you select the correct partition.

 

After finish executing all of the commands restart your computer to check if Windows boots normally.
