Create a new win7 system repair disc. Or use another win7 install dvd to do the startup repair

I do have a win7 system repair disc. Its very confusing as to what the volume is stored on, sometime its E, sometime its C. So it makes it hard to keep track of.
I'll try those steps you posted, thanks again.

A drive letter is just.... a drive letter. It depends on the OS how the letters will be.

Create a new disc!! It behaves very strange now.

Does the repair disc have to be made on the same machine its used on? Or can I make a repair disc from any machine running Win7?
Only problem I have is I'm running win7 64 bit. I would assume you have to have a 64 bit repair disc as well ?

Yes, then you'd need to find a system with 64 bit Win7 to make a 64 bit System Repair Disk.

You can use Win7 installation media for repair, discussed in Step 1 of Clean Reinstall Windows 7.

There is also Easy Recovery Essentials | Windows Recovery and Repair CD Downloads which is a way to buy a enhanced Repair CD download.

So I can tap F8 and use safe mode and then Repair the computer, it should fix the 100mb system reserved partition ?

F8 isn't working anymore I assume. You changed which partition is marked "Active" . You're booting from the win7 partition instead of the "system reserved" partition.

This win7 partition doesn't have the file bootmgr. Normally "startup repair" should make bootmgr file and bootmenu.

Code:
diskpart
select vol c
detail vol
detail part
Is it marked read-only? Any strange things on screen?

Please run startup repair again. Click "view diagnostic and repair details" and tell me which tests don't return with status 0x0 (success) and what the status is.

Can you succesfully create a file on C ? Just run notepad for example and save a test file.

If you tap F8 to access Advanced Boot Options then Safe Mode and Repair My Computer (Startup Repair) are two separate choices.

If you can access Safe Mode you can try to repair the OS by checking for infection with Malwarebytes and then check or repair system files using SFC /SCANNOW Command.

But if Win7 won't boot it's probably better to start with System Recovery Options Startup Repair and then System Restore, as laid out in Troubleshooting Windows 7 Failure to Start which I gave you a week ago. These steps try everything that can possibly be done to start unbootable Win7, leading up to if necessary rescuiing your files to do a perfect Clean Reinstall Windows 7 which you can then preserve in a backup image so you never need to reinstall again if it becomes irreparable.

OK I ran startup repair again and repair details were all 0x0 except for a note at the end for Root Cause saying "the partition table does not have a valid system partition"
As far as the Directories:
Windows is not on C
Dir E: Volume is reserved, volume SN is 84CE-9334.
Dir D: Windows is on Volume 4 NTFS, is active, and partition is healthy.
Here's a screenshot:

What the hack is C????
Root Cause saying "the partition table does not have a valid system partition"=> I expected the active partition has letter C... that's normal. So this is very strange

system partition measn boot partition.... so somethinwrong with Windows partition??? you did chkdsk a few days ago. "system reserved" was first active and had same problem.

Very curious...what's C???
