Hi guys
i am desperate to the point i have now created a sevenforums account for help
after accidently deleting a partition that contained a bootmgr and changing the active partition my computer simply will not boot. (after trying to install another operating system but i didnt finish installing)
i have tried every fix and solution i could find and none have worked .
ive tried command promt(bootrec), system recovery, startup repair and more. and when asked to select drivers for startup repair (because it wont detect my operating system) i dont know what to do, guys i am in serious need of help and will do whatever it takes to restore the bootmgr as i have too much valuable data to erase for a clean install.
please dont post fixes i have already tried
any help would be appreciated guys thanks !!!

when trying to fix via command promt, it always states "element not found" when trying the command RebuildBcd, it asks me Yes or no and when i select Y it says "element not found"

Hello prime853 and welcome to Seven Forums.

I'm no guru or expert so i can't solve your issue.

In the OP, you said:

When i ask for help from someone, i listen, appreciate and consider any suggestions.
I have no idea what all you have tried, and don't want to offend or bother you by suggesting something you already tried.

maybe you should re-think how you ask for help?

maybe you should give more details explaining exactly what you did so others can be more helpful:
- after accidently deleting a partition that contained a bootmgr and changing the active partition
- (after trying to install another operating system but i didnt finish installing)

hth,
David

The normal fix is to mark the WIn7 partition Active and run Startup Repair - Run 3 Separate Times
no matter what it reports. Mark Partition Active

However if Win7 is on a Logical partition you need to convert it first to Primary using Partition Wizard boot disk before it will mark Active: How to set partition as Primary or Logical.

There may be other reasons Win7 will not accept the boot files. You can create a new 200mb Primary NTFS System Reserved partition in the deleted space, mark it Active then run the three Startup Repairs to write the System boot files to it.

You can also recover the deleted partition using Partition Wizard Partition Recovery Wizard - Video Help. You may still need to run the Repairs to repair the MBR but first try Partition Wizard Rebuild MBR - Video Help.

Other steps are here for Troubleshooting Windows 7 Failure to Boot

Do you know what partition you set as active?

Did you actually delete the partition, or just change its active status, and have you tried Diskpart to set it back.

If you have an active partition, say you made the OS partition active, you can use the bcdboot.exe command to install boot files in that partition.

For example, the bcdboot C:\Windows command will put the boot files in the system partition. Using bcdboot C:\Windows /s C: flag would put the boot files in the C: partition whether it was active or not.

But it is a little hard for us, not knowing exactly what was done..and the steps taken to do it, as David mentions. And as Gregrocker says, it is very important to have a partition active.
