Im sorry, beats me
Im sorry, beats me
Thanks for providing this informative tutorial on DISKPART. I learned a lot about this powerful windows utility. I like to pick up your brain for the situation I have.
I have a black screen during start up issue. I posted a thread (long story). I have Lenovo Z580 Laptop. I did not add any hardware or alter HDD configuration after factory install.
Win 7: Black screen on boot up, before login screen?
As this community, provided guidance on my thread. I created a Win 7 repair disk using another computer with Win 7, 64 bit.
With community help. I run the partition Wizard on this Z580 and leaned that a suspicious 201.87 MB Unallocated logical partition shown in Partition Wizard.
As this unallocated - 200 MB sitting as 5th partition and violates MBR characteristics and cause booting issue.
How does suspicious Unallocated logical partition shows up suddenly?
I am not able to see unallocated partition via DISKPART. Here is my DISKPART.
Thanks for your insight.Code:DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 698 GB 0 B Disk 1 Online 979 MB 0 B DISKPART> select disk 0 DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Primary 200 MB 1024 KB Partition 2 Primary 653 GB 201 MB Partition 3 Primary 25 GB 653 GB Partition 4 OEM 19 GB 679 GB DISKPART> list volume Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- ------- Volume 0 F DVD-ROM 0 B No Media * Volume 1 C NTFS Partition 200 MB Healthy Volume 2 D Windows7_OS NTFS Partition 653 GB Healthy Volume 3 E LENOVO NTFS Partition 25 GB Healthy Volume 4 G FAT Removable 979 MB Healthy Volume 5 LENOVO_PART NTFS Partition 19 GB Healthy Hidden

I think i see the problem
Go to diskpart
Select disk 0
Select part 2
Active
Then go to d n do
Dir /p
N make sure it has windows
If it has then
Bcdboot d:\windows d: /s
Then
bootrec /fixmbr
Bootrec /fixboot
Bootrec /rebuildbcd
Most prob this will solve it
The 200mb thing should b a system part which might have gone corrupt
"Unallocated" is not a partition. It's unallocated space. I would not expect it to show up in Diskpart.
First im concerned about ur computer starting hence gave u solution... some app may have created that partition... see its under partition
Thanks for re-looking. It is interesting to see your prospective.

You mean, this unallocated - 200 MB not sitting as 5th partition and violates MBR characteristics and cause booting issue."Unallocated" is not a partition. It's unallocated space. I would not expect it
to show up in Diskpart.
How do we consume this unallocated space then?
I did SFC /scannow using win7 repair disc, because I have booting issue.
This command returns
I did dism.exe /image:C:\ /cleanup-image /revertpendingactionsCode:"There is a system repair pending which requires reboot to complete. Restart windows and run sfc again. I ran couple of times. I am getting the same message."How do I proceed with SFC /SCANNOW ?
It give error 2
Thanks for helping.
I followed your steps:
Went to diskpart
Select disk 0
Select part 2
Active ===> Made Part 2 active
Exit Diskpart
Then went to d n do
Dir /p
N found it has windows
I did
Bcdboot d:\windows d: /s
from D:\ & d:\windows
in both cases it is not picking up. It list bcdboot help list as though I entered bcdboot /?
I tried Bcdboot d:\windows /s got the same bcdboot help list as though I entered bcdboot /?
Is Bcdboot d:\windows ==> reversible?
Do you mind, explaining what are we try doing here?
Any thoughts?

We r trying to make d drive which has windows as active boot partition
So that we could take care of the other 200mb space later
May b the correct usage is
Bcdboot d:\windows /s d:
Yes this is the correct usage checked it, here

Thanks for your idea. I did the following
I restarted . I saw two windows 7 as below:Code:DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 698 GB 0 B Disk 1 Online 979 MB 0 B DISKPART> select disk 0 Disk 0 is now the selected disk.

to pick.
I pick 1 first time & 2 second time.
It looks like I have two boot records now.
No change in outcome === > same black screen with cursor in the middle.
Thanks for helping.
Awaiting for next steps.
**** I tried SAFE Mode. It loaded couple of drivers and paused at CLASSPNP.SYS load. It went to Black screen with cursor at center. ===> Does it mean something to you?
