Windows 7: Windows 7 stopped booting; Can't repair.

Windows 7 stopped booting; Can't repair.

I searched the threads for an existing post and I couldn't find one that matched my problem. Sorry if a solution has already been posted somewhere.

I have a new Acer 1410 w/ 4GB of DDR2 memory and a 1.6 CULV processor. It came with Vista Home Premium installed, but I downloaded Windows 7 Ultimate from my technet subscription. Because I don't have an optical drive I had to install from a USB stick. I did this without any problems at all.

Windows 7 has been booting fine and running great for about a week now. I haven't recenly loaded any new software or drivers. Yesterday I shut down my laptop normally; when I tried to reboot an hour later I was shown the "loading files" screen and was then taken to the Windows Startup Repair option. Windows spent an hour trying to repair whatever was wrong with my startup and I was finally given an error message that it couldn't make any repairs.

I tried going to the DOS prompt and fixing the boot manager and boot file; interestingly all this did was suddenly give me the option to boot Windows 7 or Windows Vista (!!!). I still get the Windows Startup Repair when I try booting Windows 7. If I try to boot Vista (I was curious) it takes me all the way to the login screen but then tells me I have files missing if I try to login, which is fine - I wasn't trying to set up a dual boot anyways.

Here's the part that's really got me stumped: If I try booting my laptop into install (using the bootable USB stick I created to setup Windows 7 on my laptop) I have the option to repair my computer. When I choose this option it of course takes me to the advanced repair options where I can choose Windows Startup Repair; it runs the repair and tells me it doesn't find any problems with my computer and to go ahead and start my computer normally. Of course, when I reboot and remove the USB stick my computer doesn't boot normally; I'm taken back to the "loading files" screen and then to Windows Startup Repair where I'm told that Windows can't repair my startup.

Any help? I really do not want to have to do a fresh install if it can be helped.

UPDATE: I may have some new information. I've booted to the install menu and picked "Repair your computer". From there I went to the command prompt and typed "sfc /scannow".

I received this message:

"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."

Try taking out 2gb of ram temporarly during install or repair. There have been known issues about over 2gb ram during install. Also any un-needed extra peripherials.

Good suggestion, but it didn't work. I removed a 2GB stick and went through the Startup Repair, which reported that it couldn't fix the problem. On reboot, I was still taken to the Startup Repair which still couldn't fix the problem.

Yep, I had the same type of thing happen to me. Was working fine, and shut down.
Restarted 2 hours later, and it was messed up. Not as bad as yours, but still, enough
was missing that I had to reformat and start over again. This is some BAD type of corner case bug maybe.

Yeah, that's what I've ended up having to do. There doesn't seem to be a fix that I can find for this problem except to just start over.

Just awesome.

Some times you have to run REPAIR 3 or 4 times. I found that the repiar can fix only 1 major item at a time.

1. When you installed Windows 7 - how exactly did you install?
very important.
did you have a windows.old ?
did you mess with windows.old?
did you attempt to move {boomgr}
lots of info needed will start with this?

2. If you can boot and at least get into CMD (DOS) you might try this.
rstrui.exe /offline:C:\windows

that is ran from command line. Now if you Windows 7 is not in C:\ change to appropiate drive.

or did you do this.

I had the same problem, but mine turned out to be bad ACLs on a file, caused by a hard drive that started dying. Kg*.sys hidden and system, a DivX file. I do a system image backup to an external drive once a week, so I just restored that image and bought a new drive, then restored the image to that drive.

To me this kind of thing sounds likely to be caused by a hardware problem.
