Thanks again. It is more surprising now. I did not add any partition, since I purchased the laptop.

I did post the diskpart earlier. Here you go again.

Code:
 
DISKPART> list volume
 
 
  Volume ###  Ltr  Label        Fs   Type        Size    Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     F DVD-ROM     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
 
 
DISKPART> exit
Awaiting for your insight?

Update:

I am finding some threads talked about OEM partitions in Lenovo Z580 (subject laptop). Is it the one shows as 5th partition in Partition Wizard?

All the four Lenovo partitions including LENOVO_PART 19GB are shown in the Partition Wizard. What is suspicious is the 201.87 MB Unallocated logical partition shown in Partition Wizard. I would think that some "unauthorised" program - it could as well be a game that was tried on the machine - tried to create its own partition, failed and left the debries. Naturally it should have tried to grab some space from the other legit partitions. Once the original partition structure changed your system became unbootable. Lenovo's Partition Structure with "One Key Recovery/Restore " is very sensitive and I am sure you have seen many users trying to resize the original partitions getting into problems in Lenovo forums.

I am afraid whatever changes have taken place, cannot be undone except by a complete reinstall- Factory Restore. If your "One Touch Restore" ( which is initiated by pressing the button next to the Power Button on your machine, in the powered off condition - please read your manual page 32/33/34 ? ) works it is Ok. Or else you have get the Recovery Disks from Lenovo for your system and version of the system - G580 has many variants - if you haven't made such Recovery Disks.

Before you attempt any such "Factory Restore" which will wipe all your data :

1. Try to set your UEFI to Legacy mode and check whether your system boots. ( most unlikely but nothing wrong in trying )

2. Try to recover all data from your disk with a Live Linux CD/pendrive.( You may have to disable secure boot and change to legacy mode to boot from these.)

Data Recovery with Lucid Puppy pendrive:

Prepare a Live Linux pen drive. I would recommend Lucid Puppy ( because that is the one I had used and you have some guide on using it here in SevenForums )

Download lupu-528.005.iso (132.6 MB) from http://puppylinux.org/main/Long-Term-Supported%20Puppy.htm#lucidpuppy

Create your bootable Lucid Puppy pendrive with this ISO using Rufus 2.2 (808KB) https://rufus.akeo.ie/ (All data on the pendrive will be lost when rufus formats the pendrive before writing the ISO and so backup any data on the pendrive elsewhere before running Rufus)

Boot your PC with this pendrive using the onetime boot menu Check whether that faulty drive is shown and you can access it and see your data. If seen copy all data to the empty drive.( You must have plugged in the empty drive before booting into Lucid Puppy and see it along with other drives/partitions)

Welcome to this thread. Thanks for looking into my issue. I appreciate your assessment.

I did see UEFI Boot Legacy mode was [Enabled] in BIOS by Local default setup. I changed to [Disabled] & tried to boot ===> Same outcome (Black screen with cursor in the middle).

I reviwed your link (Lucid Puppy way to recover files from a non-bootable computer) , where you mentioned

if after trying out the various Windows Repair Options, Windows refuses to budge and only a reinstall is the option,
Did we try all the options before leading to reinstall? Here are the things we covered so far. Please correct me, if I miss something

Do we need to address the items with ???? before going to reinstall?

I have three(3) user logins in this laptop such as Admin, Local user1, Local user 2. The regular use of this computer was with Local User 1 primarily, that does not have admin rights to install/configure disk partition etc .

How does a "unauthorised" program/games alter the disk structure without Admin rights?

How do we protect the partition (OEM hidden) required for "One Key Recovery/Restore " operation during our clean install?

Do we able to backup this partition (OEM hidden) using Lucid Puppy?

As I mentioned earlier, I have three(3) user logins in this laptop such as Admin, Local user1, Local user 2.

What are the additional steps required to preserve the data within these logins?

I have installed various tools/software in this laptop.

Will I able to restore (bring back) all installed items (Software/tools/Registry entries etc) during this process?

My HDD capacity is 750 GB. What kind of media to use for backing up my data using Lucid Puppy?

Will Read/write CD work?

How do I restore back after setting to factory default?

How do I bring back all the windows 7 updates todate?


Thanks for helping.

What do you guys think of:
- deleting that 201MB unused partition (the logical one) and re-running the startup repairs? It doesn't even show in diskpart

After reviewing GokAy's suggestion,

What do you guys think of:
- Merging that 201MB unused partition (the logical one) with existing NTFS partition ?

Is it a option to consider?

What do you guys think of:

I was told about another option of EXTEND. Please review

How does suspicious Unallocated logical partition shows up suddenly?



Thanks for sharing .

Deleting and/or extending the added extra partition will work, if and only if the disc is converted back to a basic disc again after that deletion/extension; otherwise not.

So the story of conversion comes back, and you have no other place to go without doing it.

And, when the story of conversion comes, then those two terms comes back, destructive conversion and non-destructive conversion.

For a destructive conversion, follow post #83 by jumanji.

For a non-destructive conversion, the only way I can say that is to use the Partition Wizard bootable CD version 4.2.2; which offered this conversion as a free feature. But I dont know how you can get it; that is stopped years ago. Here is the method:
How to Convert Dynamic Disk to Basic Disk | MiniTool Partition Wizard Tutorial
If you buy partitin wizard, then you will get access to this option.

Finally, doing this and that, making multiple threads, avoiding good suggestions and paying attention to easy to look but baseless to work suggestions will not solve this issue. Either you pay heed to what is already stated by jumanji and me, or get the PC to a repair shop. Remember that there is no fix button there, at least for this issue.

Thanks for help and guidance. I did not avoid guidance & suggestion of thread. It is my mistake to keep only windows restore points help in recovery. I did not think about image backup, because I am familiar about this. I did not anticipate this situation.

I learned from this thread that I am able to copy personal files using Repair Disk. I do have lot of installed software/tools for which I do not have KEYS to reinstall. I did review threads about backup in this forum, but I am not able to find a way to do that. I did open multiple threads to learn about potential root cause of this issues.

Here are some questions, I have about backing up strategy. I need your guidance/pointer.

How do I able to backup OEM Hidden partition (recovery partition created by Lenovo factory install)?

I have three(3) user logins in this laptop such as Admin, Local user1, Local user 2.

Are there any backup/restore software to pull/push user by user?

What are the additional steps required to preserve the data within these logins/users?


Will I able to restore (bring back) all installed items (Software/tools/Registry entries etc) during this process?

My HDD capacity is 750 GB. What kind of media to use for backing up my data?

Will Read/write CD work?

How do I restore back after setting to factory default?

How do I bring back all the windows 7 updates todate?

"Unallocated" is not a partition. It's unallocated space?

Thanks for looking into my issue. I like to share my findings for collective learning of this forum. I am not challenging the folks, who contributed to this thread.


Code:
 
 @jumanji 
Once the original partition structure changed your system became 
unbootable. Lenovo's Partition Structure with "One Key Recovery/Restore " is 
very sensitive and I am sure you have seen many users trying to resize the 
original partitions getting into problems in Lenovo forums.
Code:
 
From Lennovo
 
 
If you made any changes in the partition like (D drive, E drive).
 
 
As if there are any other partition made then the one key recovery(OKR) may 
not work.
As I reviewed the disk conversion strategy, it will disrupt built in one key recovery(OKR). It shows as RED light.

Will some one enlighten me on this subject?




Code:
"Unallocated" is not a partition. It's unallocated space, that would not expect 
it  to show up in Diskpart.
I did research on above quote on this forum that point me to

Tutorials - Partition / Extended : Logical Drives

The post # Post 43 thru 47 resemble my Z580 condition, where 4 partitions & 1 unallocated space is showing up in MBR kind. It booted successfully and showing Disk Management in the post.

It looks like normal to have unallocated space with 4 partitions in Win 7 and some factory install keep it that way.

I'm wondering, why this condition leads to non bootable situation on my Z580?

Thanks for helping

Update 8/20/2015

I did the following DISKMAP using HIRENS_CD. It is not showing 5th partition/unallocated space. It looks like health map.

What do you guys think about it?

Thanks for your insight.
