Windows 7: BCD is wrong

BCD is wrong

Hi all, I need some help.

When SP1 was released instead of slipstreaming it myself I found an ISO with it already included.
All has seemed good for a long time but I have just found out that this ISO was altered.

Instead of winload.exe the BCD points to a file called xOsload.exe and instead of
ntoskrnl.exe I have xNtKrnl.exe. I believe it's some kind of crack that I don't want because I have a genuine licence.


It gets worse because I have tried to fix it myself, I deleted the altered files xOsload.exe and xNtKrnl.exe and also the BCD and have been trying to rebuild a good BCD, but now it will not boot at all.

I now just get the Launch Startup Repair and Start Windows Normally option.

For future reference, you can find good quality/unaltered ISO here: Microsoft

What happens when you select 'Start Windows Normally'?

I might have fixed it

From the Windows DVD-Repair-Command

Del D:\Windows\System32\xOsload.exe
Del D:\Windows\System32\xNtKrnl.exe
Del D:\Windows\System32\Drivers\oem-drv64.sys
attrib c:\boot\bcd -h -r -s

ren c:\boot\bcd bcd.old
bootrec /rebuildbcd

Now Mark Partition Active the Windows 7 or it's 100mb System Reserved partition (preferred if you have it) and then run Startup Repair - Run up to 3 Separate Times

We use automated repairs here which test and repair all parameters at once, not dated XP-era Command line one-off fixes.

Startup Repair couldn't repair it, the dated XP-era commands did

It is likely not repaired.

There are still many parameters that need testing and repair which is what Startup Repair does and bootrec/bootsect commands cannot.

For example, do you have the Repair My Computer link still on F8 Advanced Boot Options, which is lost when bootrec repairs the boot but cannot rewrite the link?

For this reason I wanted to you confirm the Active partition (always important) and run Startup Repair to see if all parameters where repaired. This is why we use automated repairs.

Yes I always try the auto repair first, but often it takes more than that.

Do you still have Repair My Computer on F8 Advanced Boot Options, or not?
