Boot manager failed to find OS loader

#1
Hi There!

Problem with vista boot up, this is the error that the vista recovery start reparation says (from recovery partition) and oh yeah, I automatically get to the recovery thing:
Root cause found:
--------------------------------
Boot manager failed to find OS loader.

Repair action: File repair
Result: Failed. Error code = 0x2
Time taken = 156 ms

Repair action: Boot configuration data store repair
Result: Failed. Error code = 0x2
Time taken = 0 ms

I have run chkdsk with /f and /r, there were errors, but now there are none.
Bootrec /scanos or /rebuildbcd gives zero identified windows installs, strange considering the start repair thing found it, but could not fix it.
i have run /fixmbr and /fixboot also, and these succeded, but still the same error.

Anyways - the reason for this to occur in the first place is a little bit embarrassing, a friend of mine asked if I could help out, he didn't know what was wrong, probably some virus, there were several programs he could not start - he gave me his computer, I immediately took out the harddrive and put it in a usb dock connected to my computer and first ran chkdsk (some errors) and then ran panda antivirus(found some viruses), I then though that these things was his problem - I though I was done. I was in no rush, so I figured I'll run a defrag and did so. When I after that put the hdd back in the computer I realised that he hadn't shut down his computer, but put it in hibernate! Windows loaded the files and I was at the desktop, but almost anywhere I clicked there were of errors telling me "run chkdsk, file error blablabla" got it to start shutting down, but it couldn't finish and I hit the power button.
The embarrissing part is of course that I didn't check that the computer wasn't in hibernation. This has never happened to me, no one has ever given me their computer for me to fix - and the computer was in hibernation.

Anyways, I then took out disk again and ran chkdsk which came up with _tons_ of errors.
And yeah. Now I'm stuck.

Thankfull for any help - I've searched the web for hours and hours, but found nothing that could help me :frowning:

Hi Mahmoud!

I seem to be getting somewhere, I now created a new bcdstore - And now I get this error:
FIle: \Windows\System32\Winload.exe
Status: 0xc000000f
info: The selected entry could not be loaded because the application is missing or corrupt.

LaL. should I just try and place a new winload.exe from my working vista into this computer?
And when I run startup repair, now from CD(the comp doesn't start auto from recovery partition any longer), it says the same thing - so one part of the error is gone....it now has a working bcd ....

Thx for helping me out! :smile:

Just a note though:
I did not use bootsect, but only bootrec /fixboot instead, since I do not have bootsect. Does it matter? And bootrec failed to /rebuildbcd - I did it manually according to instructions

Usually that means that the drive you put for the entry is incorrect.

This is really funny, it was actually - not there. so I copied over a new one - then it was missing something else, and the windows vista repair CD said it couldn't fix that either because Windows Resource Protection data was corrupt or missing. So I copied over that file too, and now there was another missing file---
I started to copy in everything that goes into system32 catalog - and alot of files were missing.

And now it loads alot of drivers before giving me a bluescreen saying I should disconnect new hardware, I might have a virus, I should run chkdsk and whatever.
And still Startup Repair tells me it can not fix anything since WRP Repair is corrupt...

I though I would give the recovery partitions repair thingy a second chance, so I reinstated the old bcd, and now it seems like that one is working again...it gave the option whether to start windows normally or launch startup repair :tongueout:
And it gives me something like unspecified changes in the systemconfiguration(hardware configuration) is causing the problems...

Addendum:

Gah. If it doesn't give me something more specific, then I might have to do a complete system restore after all :frowning:

Unless someone has a really good idea about what to do :wink:

Looks like you lost your system files due to drive corruption. You're now in between a rock and a hard place - if you have a backup, this is the time to use it :smile:

Yeah. The only question is, was it caused by my actions - could it be like that? Or was this the case even before my actions were taken. I will anyway check so that the future computers that I intend to fix is shutdown completely and not in this freakin hibernation, which sucks anyway :tongueout:
