My computer reads missing operating system

[gregrocker]

Sel Disk first, then sel each Vol to see which is marked Active.

Continue the commands Kaktussoft gave you to determine which partition is marked Active then run 3 Startup Repairs no matter what it reports.

If you didn't save a Win7 backup image that option is not available to you. But REcovery may run from its hotkey or by marking it Active. But work through the steps I gave you earlier first to do everything possiblee to rescue your install unless you're ready to rescue your files and skip to running Recovery or Reinstall.

@greg: "missing operating system" is a message that comes from MBR
Reason: corrupt mbr code, or maybe no active partition.

startup repair should fix that I know. I hope he can access the recovery environment

Yes, Kaktussoft, sorry for interfering as you correctly tried to ascertain that OS partition was marked Active.

Then if Startup Repair x3 doesn't work he can try to manually use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows, run Recovery if necessary marking it Active first, or Clean Reinstall - Factory OEM Windows 7 after rescuiing files.

I only wanted to make sure he has all the steps up front, including to try to get disk to boot since System Recovery Options sometimes do not work as well from F8 and require the Installer or Repair disk.

I'm new to this I don't know how to select disk and then view to see if its active can you be a little more specific plz?

No problem Greg.. any information is welcome. But I think bootrec doesn't work, because he hasn't selected a win7 os in the list. At least that's what I read between the lines.

Anyway... bootsect works as well

[Victor staggers]

[Kaktussoft]

Ver very strange but do this:

diskpart
sel  vol  d
active
det  part

Now it's active... correct?

 

[Victor staggers]

Yes

 

[Kaktussoft]

Is volume D active now? if so type: exit

 

[Victor staggers]

Yes it is active now ...

 

[Victor staggers]

I typed exit... What's next

 

[Kaktussoft]

Yes it is active now ...

exit diskpart by typing exit
#22 read that please. Nothing was marked active!!! Computer didn't know where to boot from!! Try to reboot normally now. And post results

 

[Victor staggers]

Now that I exited ... It found problem and restarted but now its saying missing bootmgr at start up

 

[Kaktussoft]

Now that I exited ... It found problem and restarted but now its saying missing bootmgr at start up

Boot again form DVD and do th shift+F10 trick to enter command prompt

DIR  D:\
ATTRIB  D:\BOOT\BCD

Do you see files and folders? Does second command show a file?

Maybe better do a "startup repair" (I think it works now)
