Re-partitioning causes Booting issues

After recovery from a boot problem I managed to get the laptop up an running with all drivers.
Figured needed to repartion my secondary drive,I have two HDD (750GB each), and used mini tool to format and resize the secondary drive. I also used it to hide my recovery partition and change drive letter of all but the OS (C drive).

Happily rebooted to see that windows is loading files bar coming up which quickly ended with “Reboot and Select Boot device or Insert Boot Media in selected Boot device and press a key” message.

Need help to sort out and going to BIOS didnt help. I have not touched the BIOS config ever since i got this laptop.
When I set the BIOS to boot from CD/DVD and put in the win7 recovery CD disk it doesnt read it. DVD light is blinking.

Not sure if ASUS G75VW come wit IDE or ACHI as I did accientally change and save.
System : Win 7 64 bit, i7

If you can boot the PC with Windows post a maximized and re-sized screen print of disk management using these instructions:
Disk Management - Post a Screen Capture Image

If you can't boot Windows, try creating and using a bootable Partition Wizard CD and post (camera) screen prints of what you see.
Bootable Partition Manger | MiniTool Partition Wizard Bootable Edition

I used the command prompt to get in via the win 7 repair disk i created from another laptop.
Seems like the OS disk is GPT.

I get "Element not found" when I run fix boot and on startup repair the log shows
"root cause found the partition table does not have a valid system partition..fixed"

However rebooting doesnt solve this.

Try removing the secondary HDD and re-run startup repair perhaps?

Troubleshooting Windows 7 Failure to Boot

Especially important for you:

A UEFI install to GPT disk must have its installation media or Repair CD booted as a UEFI device. A UEFI install has a EFI System partition instead of System Reserved, and a (hidden) MSR partition, can only boot from a GPT disk. Confirm using Diskpart commands or free Partition Wizard CD that these partitions are intact and run Disk Check on all of them including Win7 partition. Then from System Recovery Options run Startup Repair and if necessary System Restore.

Screenshots from partition wizard attached. Everything seems okay from them or maybe I'm missing something.

Before I remove HDD I just want to confirm if there is anything I can do to get it to boot .
From the post above I see that the system(200MB) partition is GPT(EFI syste,) and is active and boot.
Should I make the OS partition as bootable?
I know that the system partition should be active.

Try running startup repair 3 times with a reboot after each.

Startup repair multiple times doesnt help.

But doesnt work for me.

fixboot still gives element not found.

You did remove the 2nd HDD before trying the repairs, right?

No I did not. Oops..Will try doing that and post back.
