About Windows loaders
Windows NT/2000/XP/2003
A part of the loader resides in the partition boot sector, the rest is in the files ntldr, boot.ini,
ntdetect.com, ntbootdd.sys. boot.ini is a text file that contains the loader configuration. Example:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional"
/noexecute=optin /fastdetect
Windows Vista/2008
A part of the loader resides in the partition boot sector, the rest is in the files bootmgr, boot\bcd. At
starting Windows, boot\bcd is mounted to the registry key HKLM \BCD00000000.
6.3.12 Recovering a vast number of files from a file backup
Applies to: Microsoft Windows Server 2003
When recovering a very large number of files at a time (hundreds of thousands or millions) from a file
backup, you might encounter the following problem:
The recovery process fails, and the message "Error reading the file" appears.
Not all of the files are recovered.
The most likely cause of the problem is an insufficient amount of memory allocated to the recovery
process by the operating system's cache manager. You can either work around this problem or
modify the registry to increase the amount of allocated memory, as described below.
To resolve the problem, do either of the following:
Recover the files as two or more groups. For example, if the problem occurs when recovering
1 million files, try recovering the first 500,000 of them and then the remaining 500,000.
Modify the registry as follows:
Note: This procedure requires restarting the machine. Use standard precautions when modifying the
registry.
1. In Registry Editor, open the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management
2. Add the PoolUsageMaximum entry to the subkey:
Entry type: DWORD Value
Base: Decimal
Value: 40
3. Add the PagedPoolSize entry to the subkey:
Entry type: DWORD Value
Base: Hexadecimal
Value: FFFFFFFF
4. Quit Registry Editor, and then restart the machine.
