Partition Recovery In Case of Unbootable Boot Disk
Allen Sood
August 26, 2009
Sometimes your NT Based Windows operating system might not start if "multi()" syntax is used in Boot.ini file on X86-based computer and their first sector of hard drive partition on which Microsoft Windows is installed is 4 GB or more on the hard drive. That is, if cumulative size of other hard drive partitions and the unpartitioned free space before partition on which the Windows operating system is installed is equal to or larger than 4 GB.
In such cases, the Windows system become unbootable and all of the hard drive partitions become inaccessible. This behavior of Microsoft Windows results into critical partition loss situations and require Partition Recovery to be sorted out.
In a practical scenario, when you attempt to start your Windows computer that use "multi()" syntax in the Boot.ini file, you might come across any of the below given error message:
"Boot record signature AA55 not found (25EB found) Windows NT could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows NT documentation about hardware disk
configuration and your hardware reference manuals for additional information."
Or
"Windows NT could not start because the following file is missing or corrupt: Windows NT RootSystem32Ntoskrnl.exe"
At this point, to get your lost hard drive partition back, you need to find out the cause of this issue and go for Partition Recovery by resolving it.
Grounds of the problem
You might come across this problem by some miscalculations that take place during boot sequence of the system where Microsoft Windows is trying to complete starting location of partition to which the operating system is installed.
As stated in the second error message, this problem may also occur due to corruption to the Ntoskrnl.exe file. This is the Windows kernel file for NT based versions of Windows operating system. Due to corruption to this file, Windows system can not boot up and thus you encounter this situation.
Resolution
In order to sort out this issue, you need to install latest service pack of your Windows operating system. To recover lost hard drive partitions, you are required to go for Partition Recovery Software.
