Symptoms of the error loading operating system windows xp virtualbox problem When computer is 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 https://neosmart.net/wiki/error-loading-operating-system/ boot sequence is shown as 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 http://www.prime-expert.com/articles/b13/fix-error-loading-operating-system.php control to first additional sector of 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 messa
other operating systems should not face this problem. Essentially, the Error Loading Operating System error occurs at a point between the computer's http://www.tech-faq.com/error-loading-operating-system.html BIOS running checks on the system's hardware and the actual launching http://www.computerhope.com/issues/ch000730.htm of the operating system. This error is usually accompanied by a black screen and occurs directly after the installation of Windows XP. What Causes this Error? The Error Loading Operating System error occurs when there is an issue with the way the BIOS and the Windows XP error loading operating system are communicating with each other. Most commonly, the BIOS has an issue where it does not support or has no way to correctly manage the capacity of the hard drive that Windows XP was installed to. How to Resolve this Error The Error Loading Operating System problem can be solved in a variety of ways. However, it error loading operating is important to have some knowledge of computers before proceeding with any of the suggested solutions to this error message. Not knowing exactly what to do or failing to follow the directions on the computer screen could result in the computer being corrupted or destroyed. Changing or flashing the BIOS can have detrimental effects on the computer and should only be performed if the user is completely sure about what he/she getting into.

Alternatively, someone who built their computer should consult the manual that came with the motherboard. Once the user is sure that his/her BIOS has been upgraded to its most recent version, determine which type of BIOS is being used. Each BIOS is somewhat different and newer versions of popular BIOSs tend to change the locations of different functions and features. Therefore, users should consult their computer vendor, motherboard manua
drive's size or settings This issue is often caused when the BIOS does not properly detect the hard drive. To resolve this issue, update the computer motherboard's BIOS. Additional information and help with BIOS updates. Computer Hard drive is not properly setup in CMOS Verify that the computer's hard drive is properly setup in CMOS setup. Once in CMOS, verify the below hard drive settings. Verify the hard drive is detected. Try changing the "Access mode" on the hard drive to Large or LBA. This setting may vary depending on the BIOS. Issue with drive's partitions This issue can be cause if the disk drives are not properly setup or have been changed by another program, such as a utility that comes with a Linux distribution. To resolve this issue, delete, and recreate all the partitions before running the Windows XP setup.
