Windows 7: Computer does not startup

Computer does not startup

Okay, so I wrote a very long question with about 40 minutes of information but because of the stupid security on this website it logged me out when I clicked post... I am very upset now but anyways here is a short summary of my problem.

My computer partition table got deleted.
I tried to run bootrec.exe and everything it includes ... it failed
/fixBoot returns element not found
/fixMbr returns successfully completed the process
/scanos returns windows installations found: 0

I want to recover my windows operating system and partition table.

I used the command prompt in my windows 64 bit installer disk
The laptop I use is not older than 2 years. I use it only for Reverse engineering, C, flat assembler and pretty much for my security consultanting contracts.

Thank for any help. Please ask if you need more information. I am really upset right now because it logged me out when I clicked post last time after typing 40 minutes of information on this post... Thank you very much for any help and advice that you can give me on solving this problem. Sincere gratitude to all of you!

Poor way to enter a new forum by lambasting its "security" It never has logged me out in over two years.

How did you delete the OS partition?

I was creating a security framework for one of my contracts and it required a system debug. I had to meddle with the SDA and SDB virtual allocators on my partition and apparently it deleted my partition table and my OS somehow. I never even thought possible. I wasn't taunting the security here you just must understand that I took 40 minutes to write a nice long elaborate message about my problem then i clicked to post and it logged me out and told me to re-log. I wasn't "lambasting" anything. I was simple pissed. So I re-wrote this simple vague message above to explain the problem... Thanks for starting to assist me, very much appreciated that people here actually care.

I wonder if Linux wrote to the MBR? Are you just getting a blank screen when you attempt to boot?

This can get pretty complicated but NTFS-dot-COM has some pretty slick software to correct several major disk problems including the MBR. The drawback is that you need a working system with the software installed to work on the disk. You would need to remove the disk and "install" it in another system. But I don't think the alternatives will be pleasing if you don't have backup. I take it you've ruled out a Windows re-install?

When I boot up my laptop without the recovery disk it says as follows:

Intel UND1, PCE-2.1 (build083)
Copyright (C) 1997 - 2000 Intel Corporation

This product covered by one or more of the following patents:
US5, 307, 459... goes on with a ton more

Realtek PCIe FE Family controller series v1.27 (10/31/11)
PCE-E61: Media test failure, check cable

PCE-M0F: Exiting PXE ROM
Reboot and select proper boot device
or insert boot media in selected boot device and press a key

Also, regarding the link britton sent me. If I install it on a usb and set to err.. what was it again... oh yea. and set it to FAT32 and set to boot from usb on boot settings. will I get that screen from the downloader? I don't think so because it would have to include the dynamic link library (dll) to be compatible to execute from netStartup. Anyways, that's the message I get on startup...

Boot into BIOS setup to see if HD is detected. If not reinstall HD, swap/replace cables, or replace the HD.

If so make sure HD is set first to boot in BIOS boot priority.

Next boot the Win7 DVD or Repair CD using the one-time BIOS boot menu key at boot. Does it find an installation to repair? If so run Startup Repair a few times.

Bootrec and all other commands are automated in Startup Repair. If it doesn't find something to fix, then work thorough the other steps for Troubleshooting Windows 7 Failure to Start.

I am going to try all these useful tips now. But no, the windows 7 DVD does not find an installation to repair. As I stated in the first post - The bootrec.exe /scanos found no installations. Thanks.

I really have to refresh the screen BEFORE I post. Sheesh, Greg post the link 30 minutes before I wrote or posted this.

Sorry folks.

I read what you wrote in the first post which is why I said to run Startup Repair instead of XP-era bootrec commands, which are all automated now in Win7 Startup Repair along with multiple other tests and fixes.

Bill: There's no problem with repeating steps or tutorials as it doesn't confuse the OP as much as reinforce the direction being suggested.
