BootMgr is missing

[georgesmith1]

Earlier this evening I installed 64Bit Window7 Professional on a new formatted hard drive. I already had a copy of 32 Bit Vista Home Premium Edition SP2 running on the pc on another hard drive. After updating Windows 7 from the Windows Update site I was told to restart the pc to complete the installation of the updates. The BIOS now hangs up at the BIOS splash screen and then I get the message " BIOSMGR not found press CTR+ALT+DEL to restart" . I follow these instructions and the same happens again. Can anyone advise how to solve this problem?

He can't boot in to Disk Management to post it. As computer starts up, go into BIOS by tapping delete, F1 or F2 repeatedly. See which HDD is set to boot.

Did it ever actually start up to a dual boot menu after install? Did you unplug the Vista drive to install 7 and then replug it? If so, try to boot from the Win7 disk and run startup repair. If it offers it to you when you select "Repair my Computer" it may not work the first time, so boot back in after it fals and select it from Repair Menu to run.

If that fails, boot back into Repair Console>Command Line and run "bootrec.exe /fixboot" and "bootrec.exe /fixmbr" to fix the boot manager.

If these fail, then post back here what you found.

Thanks for you prompt response.

I managed to get into the BIOS as per your instructions.

Boot Disk Priority:

1st Boot Device: Internal Hard Drive with Windows 7 intalled.
2nd Boot Device: Optical Device -CDROM.
3rd Boot Device: 1st Floppy Drive (Don't actually have a Floppy Drive installed.

Note: The hard drive with Vista doesn't appear to be listed however I saw somewhere recently that this may appear as a Floppy drive in a system even if a Floppy Drive is not present? Also the is a comment on the side panel that says that if the drive is bracketed then it is disabled. The drive names all appear to have square brackets.

Hard Disk Drives:

1st Drive: Internal Hard Drive with Windows 7.
2nd Drive: Internal Hard Drive with Vista,programs etc.
3rd Drive: External Hard Drive-Data
4th Drive: External Hard Drive-Data.
5th Drive: Internal Hard Drive- Data.

In answer to your other questions:

It did start up to a dual boot menu after the install.
I did not unplug the Vista drive to install Windows 7.

Should I now go ahead and try your suggestions of trying to boot from the Windows 7 disk and and run startup repair or given the above Boot information do I need to do something else first.

Hi George -

You will probably want to put your optical drive in the first boot position by default so you can boot into your Win7 install DVD, unless you are doing so with a shortcut key. Keep your Win7 as first HDD listed.

When you say you got a boot menu in the beginning, were you able to access both OS's?
How many times did you get into either before the problem commenced?

Is this the error you are getting: http://www.howtogeek.com/howto/wind...ing-error-while-trying-to-boot-windows-vista/

Boot into the Win7 disk, select "Repair my Computer" and run startup repair. It will run every conceivable test/fix (including system restore) until it exhausts all. Still it may need to be run more than once if there are multiple problems so I'd give it 2 more chances if restart fails to boot.

The Updates seem to have bollixed your startup somehow, so I'm guessing System Restore will need to run. If Startup Repair doesn't handle this properly (and it should) then as a next step I would boot into the Repair console again and choose System Restore and restore your Win7 to before the updates.

If that fails, boot back into Repair>Command Line and run "bootrec.exe /fixboot" and "bootrec.exe /fixmbr" then restart. If those don't work try "Bootsect.exe /nt60 all /force" (all without the quotes).

Greg:

Regarding the OS's I did get the BIOS page that gives you the option of choosing the OS and the Windows 7 was top of the list and I selected that. I'm not sure if I went back and checked that Vista was still operating as I was interested in seeing What Windows 7 was about. I don't think that I shut down and rebooted but went straight ahead to Windows update where 8 updates were listed but only 7 of which were ticked. I remember ticking the 8th and then installing. The usual message came up that I needed to restart the computer to complete the installation of the updates. I restarted the computer and the BIOS error message appeared eventually.
Re your 2nd question the error message is the same shown on the howtogeek weblink

So what did the Startup Repair report?

Hi Greg:

I followed your instructions and both OS's are working fine. When I booted into the Windows7 DVD and followed the instructions it firstly did a System Recovery Repair of Windows 7, Vista and then the Windows Recovery Environment and then I was able to access the Startup Repair window. It went through the various checks and identified the root cause as the Boot Manager missing or corrupt and repaired. Everything appears OK since then and I have carried out Windows Updates of both OS's.
Finally I must thankyou again for all your help in this matter.
