Windows 7: Windows 7 Won't Start or Reinstall, System Partition Missing?

Windows 7 Won't Start or Reinstall, System Partition Missing?

It's been a while since I've posted here, but I'll spare the reintroduction :P

My specs:

ASUS M5A97 (AM3+) Mobo
AMD Phenom II X4 945
2 x 4GB G-Skill Ripjaw DDR3 RAM
PNY Nvidia GeForce 460 GTX 1GB
A 1TB SATA HDD (can't remember the brand)
A 160GB SATA HDD

My issue is, I'll try to boot into Windows 7 Ultimate x64, not a new installation at all, and I get the "Windows is Starting" screen and the little colored balls, but after a few seconds I get a very very quick blue screen and reboot before Windows even loads. There's no way I can read the blue screen error.

So I thought, "Let's just do a startup repair." That didn't work; it said:

Quote:
Root cause found:
--------------------------
The partition table does not have a valid System Partition

Repair action: Partition table repair
Result: Completed successfully. Error code = 0x0
Time taken = 20632ms
---------------------
---------------------
So I pop in the Windows 7 installation DVD; it tells me there are missing CD/DVD drivers. I point it to the Windows 7 drivers directory on my primary HDD, it still can't find anything.

So I load up my copy of MSDaRT. Some tools load, but it tells me "Tool requires a supported offline OS" under many of the tools, and the ones that do start won't do anything at all because they can't "see" my Windows 7 installation.

Any suggestions? I have an external HDD reader, but I'd rather not have to wipe everything and do a clean reinstall. Maybe trying to fix the partitions with a G-Parted on an Ubuntu Live CD or something?

Press F8 on boot so you see Advanced Boot Options
and select
Disable Automatic Restart on System Failure
Now you can see the BSOD if windows boots.
Post it please. But I think something is wrong with partition table

How many partitions do you have on the disk, and how many disks?

in recovery environment->command prompt:

diskpart
list disk (now you see how many disks, detach any external drives first)
sel disk 0
list part (now you see the number of partitions)
sel part 0
det part
sel part 1
det part

etc.
Give me the number of disks please. and number of partitions on disks

So I pop in the Windows 7 installation DVD; it tells me there are missing CD/DVD drivers????
=>sounds impossible you're booting from dvd then! What's exact message?
How did you perform the startup repair... did you boot using F8?

Gimmie a second, I'm going to answer all of your questions. For now here's the blue screen error:



Off the top of my head, I have 2 hard drives. My primary (1TB) hard drive has a Windows 7 installation in it with the standard partitions, nothing fancy. The secondary hard drive only has some movies and music and stuff on it that I wouldn't want to lose if something like this were to happen. I'm getting you the detailed information though.

I tried the recovery environment both from the 7 installation on my HDD and also from the 7 install disc. I'll get you a picture of the error from the install disc in a second.

Funny, now that I re-ran Startup Repair, it says:

Quote:
Root cause found: A patch is preventing the system from starting.
It seemed to see my installation this time though, labeling it as "E:\Windows" (during actual computer use it's the C:\ drive though).

E: or C: who cares! It is just a drive letter and can change and depends on which OS you're booted. Now you booted from DVD. But actually it's the same partition

Try to perform a "system restore" to a date PRIOR to problems.

This is so weird. Before, it wouldn't see any partitions, so system restore would error out, telling me it can't see a Windows installation. But now it does. I'm rolling back to the last Windows Update. Trust me, I would have done this before, but it wasn't seeing Windows. Now all of the sudden it does.

If it can't see win7 it doesn't know what to "system restore". Same issue with ms DART.
But this was the error
"The partition table does not have a valid System Partition"
And it was repaired with status 0x0 so succesfull. Sure you you tried another boot to recovery environment? It should see it then. I didn't fix it LOL

It sees all the restore points. I tried the one before the most recent and it failed after trying. So now I'm trying another one. Hopefully startup repair did something to make the system partition readable again so that MSDaRT will work. DaRT has much more tools.

There was something wrong with partition table (located in mbr).
Do this to check if all partitions are still there and no errors

in recovery environment:

diskpart
list vol
exit

Now you see the drive letters

chkdsk/f c:
chkdsk/f d:
chkdsk/f e:

every drive letter you see (except for cd/dvd) devices.
Any errors?

Does "system restore" crash, or just doesn't fix the problem?
