Boot entry missing

[conoflex]

I just went to msconfig to check that all my cores were enabled and there is NO boot entry there so I can't access anything on the boot tab (See attachment)
What can I do about this please.

Also I just found out that in elevated command prompt BCDEDIT is missing :
C:\>bcdedit
The boot configuration data store could not be opened.
The system cannot find the file specified.


So how can this be as computer is booting up no problem.

Are you using a non windows bootloader.

 

[Bill2]

Boot to the setup DVD and run Recovery menu. Navigate to the Command Prompt. Type the following commands one by one, hit Enter after each.

bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

No using the windows one.

Boot to the setup DVD and run Recovery menu. Navigate to the Command Prompt. Type the following commands one by one, hit Enter after each.

bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

Done that an it's still the same

The only things I can think of are:

1) Run a startup repair.

2) Run an sfc scan.

3) If nothing works, try a repair install.

Of course, you have the option of doing nothing since your computer is booting up fine.

1) Done startup repair - no good still same.

2) Done sfc scan - won't work I get this when trying -
C:\>sfc /scannow

Windows Resource Protection could not start the repair service.

3) Repair install - going to try that next will report back later.

[conoflex]

would not complete the repair install.

Have the exact same problem, only in my case I also have a dual boot Win7/Ubuntu, I am almost sure GRUB is causing my problem, but would appreciate any suggestions, (GRUB related or not).
Thank you

Post screenshot of disk management with all fields visible (from within win7).
GRUB has been installed in MBR or in "volume bootsector" (if you know)?
In linux:

sudo dd if=/dev/sda   bs=512  count=1| hexdump -c

Any readable code like "Grub" or "Missing operating system"?

UBUNTU installed before you installed WIN7 or vise versa?

 

[qwert2k8]

I believe GRUB is in MBR, of disk1, but I am not sure.
Ubuntu (Disk1) was installed after Win7 (Disk0), but I recently changed my second disk (disk1) for a larger one and had to rebuild GRUB after copying the partitions in the older disk.
I don´t know if it matters, but also upgraded processor from a Pentium D to a Core i7 and Mother Board from D945PSN to DP67BA

Thanks for your quick reply

 

[Kaktussoft]

In elevated command prompt:

diskpart
sel  vol  d:
inactive
exit

D: is not active anymore in disk management now? Try to boot in win7 and ubuntu. Works?

 

[qwert2k8]

Ok, in Ubuntu now.

When you boot you see a boot menu. In that menu you select win7 or ubuntu. But is it a grub bootmenu or a win7 bootmenu?
Win7 bootmenu looks like this:

In the disk list you posted it is on /dev/sda4 (?)

Yes, I mixed up sda and sdb
Windows 7 is in dev/sdb1
Ubuntu is in dev/sda4
I thought they were in sda1 and sdb4 respectively

Sorry for the mix up
