Windows 7: Deleted System Partition Win7 Now It Wont Boot. Please Help.

Windows 7, 64 bit
Deleted System Partition Win7 Now It Wont Boot. Please Help.

So.. I was trying to get a dual boot setup of Windows 7 and Ubuntu where I had 1 partition for Windows 7, another for Ubuntu, and a third neutral partition accessible from either OS where I would house all of my data. The problem is, my computer already had 3 partitions set up: Windows 7, the system boot partition, and one called PQService. Because I could not find a tutorial to delete pqservice, I decided to delete my system partition, even though this seemed a little more risky (apparently it was lol.) I used this tutorial: TeraByte Unlimited Knowledge Base to copy the boot files to the windows partition and delete it. I then booted into a Live CD of Ubuntu, and used Gparted to move my Windows 7 partition in order to get rid of the 100MB of unallocated hard drive space. I then attempted to restart my computer into Windows and i got an error saying that windows could not boot because of some recent hardware changes.
Is there anyway I could get back into windows without reinstalling it? Do I need to figure out some way to restore my System partition? Is there someway I could get windows to boot without doing either of those?
Any help would be greatly appreciated. Thanks in advance.

Try doing a repair using the installation disk.

Nope. You need the disk. You can not mess with that 100 mb partion.

I'm not completely sure if I should mention this on the forum, but through the proper channels you can find a system recovery .iso available for download and burn it to a cd. I've had to resort to this once while on the road after having a minor mishap.

Boot free Partition Wizard bootable CD, rightclick Windows 7 partition to Modify>Set to Active, OK. Then click on the Windows 7 HD to highlight it, from Disk tab select Rebuild MBR, OK. Apply both steps.

Reboot to see if Windows 7 will start. IF not you need the Windows 7 DVD or REpair CD to run Startup Repair - Run 3 Separate Times to write the System boot files to Windows 7 partition.

Even then, sometimes Linux GRUB bootloader corrupts Windows 7 beyond repair, so you may be faced with reinstalling Windows 7 using the manufacturer's Factory Recovery partition hotkey at boot, Recovery Disks if you made them or order them, or find a Windows 7 installation DVD to clean reinstall Windows 7 with Product Key on COA sticker: Reinstalling Windows 7

You can rescue your files using DVD/Repair CD this way: Copy & Paste - in Windows Recovery Console or using free Paragon Rescue CD.

You never attempt major system operations without having a installation disc handy. That's your chance of recovery.

The reason why you received an “Error Message” when you attempted to reboot back into your Windows 7 Installation, containing in part that there was a “Hardware Change”, is that you inappropriately moved the “Windows Installation Partition” so that it was in a totally different location on the HDD WITHOUT making the corresponding entry change in the “Partition Table” AND Master Boot Record – which is 'read' as a “Hardware Change”! Neither the “Windows 7 Installation” DVD, or any of the 'common' 'Rescue Boot CD/DVDs' is able to make a 'Repair'!
If you correctly carried out the “Part 1 – Copy the Booting Files and Configure the Windows 7 Partition for Booting” of the Terabyte Unlimited Tutorial “How To remove the Windows 7 System Reserved Partition” is dependent on whether or not your now “Non Bootable Windows 7 Partition” is 'recoverable', as is the Strategy for 'Recovery!
Would you please answer the following two questions?
Am I correct in assuming that your PC is a SATA System?
Do you have Valuable Data, which you would like to Recover if your Windows 7 Partition proves unrecoverable?
Please understand that there is NO guarantee of 'success'!

Follow the steps I gave above which have successfully helped hundreds of users repair Windows 7 when the SysReserved partition is damaged or removed.

These methods were largely developed here since Windows 7 release and not at some website we've never heard of.
System Reserved Partition - Delete
System Reserved : Create Using Disk Management
System Reserved : Create for Dual Boot

OP was also given a way to recover his files using Paragon Rescue CD or the Windows 7 DVD or Repair CD which he will need if Partition Wizard is not able to Rebuild MBR once Windows 7 partition is marked Active.

Using PW CD was offered only because OP has no Windows 7 or Repair disk, although he needs one going forward: System Repair Disc - Create
