A diagnostic says boot manager is missing or corrupt....error code 0x15. No operating system shows up in system recovery options window. I have windows 7 64 bit.

Hello and Welcome -

First try this if you can access the main screen of Windows7 -
Run sfc /scannow from An Elevated Command Prompt This will take about 5 to 15 mins (your DVD/CD is not required) -
Then run chkdsk /r from the same method as above (this may take up to 1 hour and at times more)

Next read =>> http://social.technet.microsoft.com/Forums/en/w7itproinstall/thread/3eeb82cf-8704-4f64-a781-603cb9fdd6ac

Report back after these items have been done -

Thank You -

Hi...thanks for responding. The only way I can get to the command prompt is if I boot from the Windows installation dvd. I'm not sure if that makes a difference. (I'm at work now, but will try your suggestion once I get home)

Best,
John

update: I tried sfc/scannow. It returned this: "There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again".

I did that...only to get the above message returned again.

Thx

I ran chkdsk/r

The following was returned:
The type of the file system is NTFS.
Cannot unlock current drive.
Windows cannot run disk checking on this volume because it is write protected.

First of all, did you run chkdsk/r or chkdsk /r as instructed?

Second, did you boot to a command prompt and then run it?

Last, have you tried booting to the W7 dvd and running the startup repair options?

I ran chkdsk /r as instructed. Same message, although I had a typo in earlier post...it says "cannot LOCK current drive"...not "cannot UNLOCK " as I wrote earlier.

I booted to the command prompt through the windows 7 installation dvd

I also tried windows 7 dvd repair options, but no luck

Well, I'm very surprised. Checkdisk from the command prompt should not result in a locked drive message. I'm guessing you can't get to safe mode?

See if anything here helps: http://pcsupport.about.com/od/findbyerrormessage/a/bootmgr-is-missing.htm

Allan: Maybe I misunderstood your earlier notes. I did some internet searching and tried running checkdisk this way:

chkdsk c:/r /r It's now in the process of scanning. I'll report back once it's finished.

The command is either chkdsk /r or chkdsk c: /r (assuming c: is the system drive, both commands do exactly the same thing)

I was successful in getting checkdisk to run. Screen shot is attached. Any thoughts on where I should go from here?

That's the command prompt that comes up when I use the Windows 7 boot disk. Should I be getting to a different command prompt?
