How to restore HP factory defaults without system restore Dvds if Win7 is formatted?

Question

I recently encountered a problem with pre-installed win7 in HP Pavilion Dv6 6121se laptop after replacing the old battery. The hard disk had three partitions: C, D & E. By default the windows was installed on C drive. The following operations were performed in sequence:
1-      Using Partition Wizard 7, I decided to format C drive with the idea to re-install the OS from recovery partition. I accidently changed the recovery partition from "Primary" to "Logical" during this process. Soon I learnt that the system recovery (F11) wasn’t functioning followed by this  message: No bootable device - - insert boot disk and press any key
2-      I made a system repair disk from another laptop to overcome the above issue. It didn’t work,  so I then decided to merge the C, D and  E partitions using AOMEI Partition Assistant Professional Edition. The status of the hard is asunder after merger:
Partition            File System          Capacity        Used Space        Free Space            Flag                     Status
C: SYSTEM           NTFS                     199 MB         13.8MB             185.2                    Primary                  None
D: Data                NTFS                     451 GB           99.8 MB           450.9 GB              Primary                 None
E: Recovery        NTFS                    14.45 GB      12.87GB             1.58GB                 Primary               System
F: HP_Tools        FAT32                  103MB           15.5MB             87.5MB                Primary              System
Here comes the problem:
A)      When C: SYSTEM is set as active partition, I get this message on startup
BOOTMGR is missing
Press Ctrl+Alt+Del to restart
B)       When E: Recovery is set as active partition (or tapping F11), I get this message on startup
          Windows failed to start. A recent hardware or software change might be the cause.
           File: \Boot\BCD
          Status: 0xc0000098
         Info: The windows   boot configuration data file does not contain a valid OS entry.
Please bear in mind that I didn’t make any system restore DVDs in advance which could have been used at this stage but I do have the default recovery partitions intact in hard drive as shown above. After all this, is there any way to retrieve my system to factory settings without losing recovery partition and HP tools?
Thank you all!

Answer 1

Try download a PE system and get in there and run an WIM tool to install windows to C
(Look for base.wim in the recovery partition and install it)
