Solved BSOD after Ubuntu installation, 0x0000007B error

[sniffer55]

I was having well working Windows 7 OS, but I wanted to try out Ubuntu 12.04. So I make some free space and created separate ext primary partition using Gparted utility of Ubuntu live CD and modified partition table and installed Ubuntu successfully. But After Ubuntu installation I cant boot into Windows 7. It gives 0x0000007B error on windows logo animation.

Below are points I noticed and tried after searching on some forums. But still cant find any solution.

1. I tried with system recovery option of windows 7 but my Windows 7 is not listed in System Recovery Options.

2. Below is result I get when i run diskpart. Its showing my disk status as Invalid.

DISKPART>list disk

Disk ### Status Size Free Dyn
-------- ------------- -------- ------- ---
Disk 0 Invalid 465 GB 0 B *
Disk 1 Online 7740 MB 0 B
Disk 2 No Media 0 B 0 B
Disk 3 No Media 0 B 0 B

DISKPART>select disk 0
Disk 0 is now the selected
DISKPART>list partition

Partition ### Type Size Offset
------------- ----------------- ---------- --------
Partition 1 Dynamic Data 75 GB 31 KB
Partition 2 Dynamic Data 100 MB 75 GB
Partition 3 Dynamic Data 100 GB 75 GB
Partition 4 Primary 48 GB 417 GB

DISKPART>select partition 1
Virtual Disk Service error:
This operation is not allowed on an invalid disk. The disk may be invalid because it is corrupted or failing, or it may be invalid becuase it is OFFLINE.

3. I am not able to run chkdsk as it is not able to detect my harddisk partition I guess.

4. I am able to boot Ubuntu well and working fine but in Ubuntu I can mount one windows partition on which windows 7 is installed but not another one which is just used for data. here is screen shot of gparted result.

And its showing some kind of warning for first partition sda1 as shown in screen shot.

I want help in booting my windows 7 and in anycase want to recover data of partition which I am not able to mount in Ubuntu.

Thanks in Advance.

Ironicly, your question relates to mine, but I don't have an answer; just a question. Are you using grub? Also, have you ran boot info script?

 

[sniffer55]

yes I am using grub.
No. I dint run boot info script.

Hi,

In this case 0x0000007B means inaccessible boot device. Presumably you are booting Windows 7 from the GRUB2 bootloader screen?

Yes, After installing Ubuntu my main bootloader was replaced by GRUB2 and came with Ubuntu and Windows 7 options. Ubuntu works well but Windows 7 gives error on logo animation as I mentioned earlier.

Mmmm. OK. It sounds like GRUB really stuffed the Windows bootloader. Hindsight is always a good thing, but next time do it this way:

Ubuntu - EasyBCD - NeoSmart Technologies Wiki

For now, please try this and lets see if the Windows bootloader can be fixed:

it gives following result on first command of the post u mentioned,

X:\sources>bcdedit /export C:\BCD_backup

The store export operation has failed.
The requested system device cannot be found.

OK. We need a bit more help with this - I'll find someone to take a look.

So it uses grub as bootmanger now? You select win7 and it (should) start win7 bootmgr?

diskpart
list vol
exit

You see volume with problems...what is drive letter? Do a chkdsk of all volumes (expect DVD)

chdsk/f c:
chdsk/f d:
chdsk/f e:

 

[Kaktussoft]

in linux:

sudo  ntfsfix  /dev/sda1

in winre

bcdedit/store C:\boot\bcd

post output. Maybe you have to replace C by D

Volume 2       E                            Removable   No Media

I think it is not recognizing my harddisk volumes at all. So cant run chkdsk for that.

You see C and E. C is NTFS and removable. Do you have an usb stick attached?

The only problem is OS partition is corrupt! Did you resize OS partition using GPARTED? Changed start sector?

 

[gregrocker]

The problem is that you converted your HD to Dynamic which is only meant to be used to span a partition across multiple HD's.

Partition ### Type Size Offset
------------- ----------------- ---------- --------
Partition 1 Dynamic Data 75 GB 31 KB
Partition 2 Dynamic Data 100 MB 75 GB
Partition 3 Dynamic Data 100 GB 75 GB
Partition 4 Primary 48 GB 417 GB

Apparently you didn't see the warning message.

The solution to solve this non-destructively is to boot free Partition Wizard CD version 4.2 which is the last one which offers this as a free feature: pw422.zip ISO - Windows Live.

Download the ISO, rightclick to burn it to CD using Windows Image Burner, or use ImgBurn.

Boot CD. You will need to delete any extra partition(s) you created which tipped it to convert to Dynamic before it will convert back to Basic. You may have only four Primary partitions before needing to convert one to Logical to add more.

Then follow these video steps: How to convert dynamic disk to basic disk with Partition Wizard?

After conversion you may need to repair the OS to get it to boot by using PW CD to Modify>Set to Active the 100mb System Reservd partition, then run Rebuild MBR. If Win7 doesn't start run http://www.sevenforums.com/tutorials/105541-startup-repair-run-3-separate-times.html from Win7 DVD or Repair CD.

What is C and what is E??? By start sector I mean "did you move OS partition on physical disk" so it starts at another point. Do what greg told you to do

 

[sniffer55]

I followed the way greg mentioned and now I am able to login to windows
But unfortunately I had to delete my linux partition.
Anyways I got my windows partition data back
Thanks to you guys

You cannot have more than four Primary partitions without again converting your HD to Dynamic. To avoid this convert a data partition, one which is not marked System Active in Disk Mgmt, to Logical: How to set partition as Primary or Logical.

Then shrink it from the right or left to create as many new adjacent Logical partitions as you wish for data or Linux: Partition Wizard Create Partition Video Help
