Windows 7: Windows 7 not booting or recovering saying 0 os installed

Windows 7 not booting or recovering saying 0 os installed

My sister's Dell inspiron 1545 was having issues with power. It would not charge the battery but used the plug supply and would shut off when not plugged in. Well, one faithful day last week it wouldn't come on at all. (okay, it comes on and shuts of immediately after) had weird orange light.
That is all just background info. Yesterday, morning I turned in on and it stayed on but wouldn't boot. I kept getting the launch startup repair option. start windows normally was also an option but it always brought me back to this same screen.

After looking online a bit, using the windows 7 disk that came with the laptop I was able to follow some posts and get out of that death loop. I then kept getting the message "bootmgr missing press ctrl+alt+del to restart" death loop.

using cmd I was able to copy it straight off the disk into the computer so I no longer get that message. I now get a "use install cd to repair/ file:boot\bcd status:0xc0000098. Info:the windows boot configuration data file does not contain a valid OS entry

My os is C:, My recovery is D:, The disk I am using to repair is in E:, I have Boot X: that comes up. f: is for usb and none are in. I already tried bootrec /RebuildBCD it's how I got past the other loops along with running chkdsk Drive(i did c:,d: ) /f/r. I cannot run this check for x: (protected) . At the end of the checks it looks correct with the exception of the Failed to transfer logged messages to event with status 50. line I cannot run sfc scan due to pending blah, blah ,blah reboot required restart computer. restart does zippo

I already tried all the bootrec /fix.... in cmd. f8 last known good configure.... sends me to the external disk (E: )

Startup repair cannot repair this computer automatically <---tried many, many times
System recovery options menu has no os in the list. When load drivers is selected (as it tells you to do) all my C: D: X: E: F: come up and are explore able, but anything you select you get the THE SPECIFIED LOCATION DOES NOT CONTAIN INFORMATION ABOUT YOUR HARDWARE message



Please help, I don't want her to lose everything by just fresh installing. If someone knows how to fix the bcd that would be awesomesauce. yes, I'm a noob

Well. I used a tutorial and bootloader has been completely removed and rebuilt from scratch now. At restart I now get the message: 1. insert your ......blah ..blah ..blah and

File: \windows\system\winload.exe
status: 0xc000000f
Info: the selected entry could not be loaded because the application is missing or corrupt


I used Recovering the Windows Bootloader from the DVD - EasyBCD - NeoSmart Technologies Wiki

Work through these steps for Troubleshooting Windows 7 Failure to Boot.

Is the HD detected in BIOS setup?

Here is some additional info. I now can see a operating system:

Microsoft windows 223434 mb (c OS

This is after the rebuild. It should say windows 7, being that my os is windows 7 home premium. The error I get after startup repair is ran states: Problem Details
Problem Event Name: StatupRepairOffline
Problem Signature 01: 0.0.0.0
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: -1
Problem Signature 05: ExternalMedia
Problem Signature 06: 1
Problem Signature 07: OsVersionMismatch
OS Version: 6.1.7600.2.0.0.2561
Locale ID: 1033

also,
after I try sfc /scannow
There is a system repair pending which requires reboot to complete. Restart windows and run sfc again.
I sure you know how that turns out

Enter BIOS setup by tapping the key given on first boot screen, look under Storage devices for HD's. If it's not there check the cables to make sure they're good and connected securely. If so, replace the HD.

If HD is registered in BIOS, test it as given in the Steps then continue with the troubleshooting steps.

It appears BIOS recognizes a HD although it doesn't specify it's model as normal. What is under Configuration? There should be a section where SATA controller is set nearby the HD listings. What is the SATA controller setting?

It appears you've gotten the Repair to recognize the installation, now work through all of the steps in Troubleshooting Windows 7 Failure to Boot to try to get it to start. You must check for infection since a badly infected system will not repair and boot until it is cleaned up.

I really appreciate you taking the time to help me <3

System Configuration
intergrated NIC-> enabled w/PXE
SATA Operation->AHCI
Miscellaneous Devices->enable external usb port checked, enable module Bay checked
function key behavior-> Multimedia key first is active



Since I last posted I tried a few things. I attempted del the mismatched bcd and rebuild it that resulted in the activation of the recovery drive D: recovering some missing stuff , like the locale and it became the active partition. I then set the active partition back to c: which is my os. windows automatically recognized that it was the correct install path and updated the info in the operating system list in the system repair box. found an error fixed it and told me to restart. I did.
(this was after I copied bootmgr.efi, bootmgr, Winload.exe, reg.exe, windowsanytimeupgrade(all3files),entirebootfolder and wininit.exe) from my laptop to a usb-> from usb to the correct locations on the c: of the laptop with the issues)


Now get the error message at startup about missing or corrupt regisrty file

The last picture in the above post is me running the recovery dvd of the cd/dvd drive. when you press f8 it just restarts the computer. When you select windows 7 it starts recovery cd. (please note that it only says windows 7 home premium because that's what I set the Identifier as while rebuilding the bcd and set it to partition=c: ) also that before d:recovered the location the location in the system recovery options box was (C: ) local disk and now says os

so back to the "missing or corrupt registry" message. 0xc000000f
So, I'm guessing I need to rebuild the registry from backup? if so how do I do that using cmd
