powered up, an error message "Error loading operating system" appears (white-on-black letters in text mode and blinking cursor): 2. Normal boot sequence Normally computer boots as shown below (Windows 7 boot sequence is shown as how to fix error loading operating system vista example): BIOS loads 1st sector from HDD (Master Boot Record), verifies 55 AA signature and transfers control to Master Boot Record. Master Boot Record scans partition table for active partition, then it loads 1st sector from active partition, verifies 55 AA signature, and transfers control to Boot Sector. Boot Sector loads 15 additional sectors from the beginning of disk (Volume Boot Record) and transfers control to first additional sector of error loading operating system dell VBR. Volume Boot Record loads BOOTMGR file from root directory of boot partition into the memory and transfers control to it. BOOTMGR loads Boot\BCD registry hive and displays boot menu. BOOTMGR is able to run memory test and set safe mode boot flag per explicit user request. But normally, it loads winload.exe when computer boots normally (cold startup) or winresume.exe (when computer resumes from hibernation). Winload.exe opens SYSTEM registry hive, gets list of drivers, loads NTOSKRNL.exe, loads drivers (*.SYS files) and transfers control to NTOSKRNL.exe. Winresume.exe loads memory dump from hiberfil.sys and transfers control to it. 3. Defect in the boot sequence which leads to Error Loading Operating System error Defect in the boot sequence which is a reason for Error Loading Operating System is shown below: BIOS loads 1st sector from HDD (Master Boot Record), verifies 55 AA signature and transfers control to Master Boot Record. Master Boot Record scans partition table for active partition. There is one active partition, so Master Boot Record tries to load 1st sector from active partition, but sector is either outside device sector count or does not contain 55 AA signature. So MBR emits "Error Loading Operating System" error message and halts machine. The rest of usual boot events does not happen.

In order to be able to use this tool, you'll have to use Command Prompt. However, because you already have startup issues, it's obvious that you won't be able to simply error loading operating run it from Windows. If you're on Windows 7, first boot from your Windows 7 Setup DVD or a System Repair Disc. Then launch Command Prompt.

user turn the computer power on, after running POST successfully computer jumps to load the operating system installed in the user computer's Hard Disk Drive (HDD). In case of Windows XP sometimes it appears that it shows an Error written "Error loading operating system". This Error appears most probably, when a computer shutdown improper like power failure, etc. This cause the operating system installed format corrupt and thus computer fails to recognize the OS installed on HDD.

Just follow the steps below and you'll get your windows running again like before. Step 1: Boot your computer with the help of Windows XP Disc (Try to use the same disc, the one you use to install your previous OS). Step 2: when the installation wizard ask you these three options: Press 'Enter' to install a new copy of windows XP. Press 'R' to repair. 'F3' to quite. Select option number 2 "Press 'R' to repair". It will direct you to Command Prompt (DOS). And then just follow the instructions given that time appearing on your Display Monitor/LCD. Note: Default cursor location on prompt starts from C Drive "C:\windows>_", so be sure to change the cursor location to another Drive like D, E drives "D:\>_". You can switch the Drive by typing"D:" and press "Enter" or otherwise drive scan will not run properly. Step 3: Now when you enter into the D drive "D:\>_" type this command "CHKDSK(Space)C:" and press "Enter". CHKDSK (Check Disk) command will start scanning your drive and will fix the corrupt format problems by itself. Step 4: When the CHKDSK scanning completes, it will show you the current status of your scanned drive. After that just type "Exit" and then press "Enter", your computer will restart. Now you can run your windows like it was running before on your computer. NOTE: This procedure can also be useto fix same problem in Windows VISTA.
