Windows 7: Windows missing bootmgr fixed, but caused more problems

Windows missing bootmgr fixed, but caused more problems

So I was trying to shrink my hard drive to make a second one for another OS. But I accidently clicked on Make Active, so I canceled my plans. The next day my computer didnt start with the message: Missing bootmgr ... something like that, I looked for a a solution online and tried everything. I succeeded on making my hard drive inactive, but now my windows wont start with Status: 0xc000000f.

I also tried to make partition 0 active, I succeeded, but I still get this message. When I try to repair it in any way on the install disc, it says I have no hard drive with an operating system on it. And when I try to reinstall Windows 7 Ultimate 64-bit it also says that there is no available Hard drive to install it on.

To change my hard drive options I used the DISKPART function on the install disc prompt thingy. I made some photos with info beneith. I really dont wanna loose this hard drive, because its like 1800 GB and build-in my computer.

Please help

First , follow the tutorial Partition - Mark as Active , use either method 2 or method 3 to mark Disk 0 partition 1 (100 MB) as active .

Then run Startup Repair , for at least 3 separate times , with restarts after every single run ( Startup Repair - Run 3 Separate Times )

Let us know the results.

Okay, so I tried to make part 1 of disk 0 active. It said it was made active, but I dont think it did make it active. Because when I do it again it should say it already is active, instead of that it said it's made active. So I did that and restarted the computer. The install disc still couldnt find an OS on my computer, and a lot of error messages were involved. So I tried it 3 times, but it doesnt really accomplish anything. I tried it again, made it 'Active', 3 times repair, but still no results.

When you ran diskpart did you run the command
list disk
select disk 0
list partition
select partition 1
active
exit
exit

If you still get the error messages, try this. I've never done it, but should work.
assuming partition 2 is your C drive that you made active.

Diskpart
list disk
select disk 0
list partition
select partition 2
inactive
select partition 1
active
exit
exit

Thnx, but I just fixed it using Windows 8 consumer preview. It work way better than the old windows 7 repair. To be more into the details: I have put the windows 8 consumer preview installer on my USB-Stick and used it to fix my Windows 7 problem. It's easier, faster and fixes it automaticly.

But thanks for the help, really appriciated

Please post back a screenshot now of your maximized Disk Management drive map with listings, using the Snipping Tool in Start Menu or by typing it into search box. Tell us which is on each partition.

I think this is the partition u guys told me to make active, even when it was made active, the install disk still made error messages when I tried to run the Repair tools. Fortunately my USB-Stick with Windows 8 installer on it succeeded to repair it. I don't know if Win8 fixed the partition part, but I do know it worked on repairing my system.

Oh, I have Windows 7 and Windows 8 on my pc now. I used the Recover drive to put Windows 8 on, not the smartest thing to do, but I made a backup of my system on an external hard drive I just bought. When I plug it in it starts the OS on the external hard drive, so I can fix it from there. It's pretty much a mess now on my hard drives, but if it works, I won't complain :P

Did you take the Disk Mgmt screenshot from Windows 8? It appears it was installed to the Recovery partition which is what is booted since it holds the Boot flag and is correctly showing letter C. However if that was your OEM Recovery partition then it has been overwritten by Windows 8.

Is Win7 installed on the D drive shown in screenshot? Try booting into Win7 now from the Dual Boot menu which Win8 installer should have created. See if the larger partition now shown as D becomes C and holds the Boot flag. You will need to keep most of your storage on that partition since it is so large, unless you want to shrink it and create a Logical partition to store data for both OS's. You should ask for our help to do this.

Windows is correctly booting from the 100mb System Reserved partition which holds the System Active flags as it should.

I do not see your External attached but it should only hold a Backup image file which is used to reimage your HD (or its replacement) if Windows becomes irreparable. If you have a Dual Boot right now with Win7 and 8 then both will be included in image. Backup Complete Computer - Create an Image Backup

Well, my external isn't attached atm. It's all working, so it's fine for now. Also, it reads my hard drives fine right now, I can choose wich OS to use when I startup my system. My external hard drives has an OS installed on it (Windows 7) and some recover files wich my system can work with, so I'm double checked.

Thanks for everything, this forum is amazing :)
