When do you need to restore Windows 7?
System restore from Command Prompt in Windows 7 is a quite useful action when your system hascrashed or cannot boot. Most users would like to restore system from a system backup instead of reinstalling Windows.
Reinstalling system is a time-consuming process, for it wipes all your files and programs. Incomparison, system restore requires less time, for it just withdraws unwanted changes andreverts Windows to an earlier date when everything was working fine.
In addition, when you buy a new computer and want to keep the old system, you can restore the oldsystem to the new computer. In this way, you can transfer everything from the old systemto the new computer. There's no need for you to reinstall your frequently-used applications.
There are three methods to perform System Restore from Command Prompt in Windows 7:
Launch System Restore from Command Prompt in System Recovery Options
When it comes to system restore with command line when Windows cannot boot, what comes tomind first is System Recovery Options Command Prompt in Windows 7. It is true. However, ifyou use 'wbadmin start recovery' command, you will get the following error:
'Warning: The START RECOVERY command is not supported in this version of Windows.'
That is because some of the sub-commands of Wbadmin are only available for server, and'wbadmin start recovery' is one of them. This command is used to restorefiles/volumes/applications that were backed up using Windows Server Backup.
Luckily, you can open System Restore by another command:
1. Open CMD in System Recovery Options, type rstrui.exe and press Enter.This command will open System Restore wizard immediately.
2. Choose a restore point and click Next. Follow the instruction to completesystem restore.
Launch System Restore via Safe Mode with Command Prompt
There is still another way to launch System Restore. You can go to Safe Mode with CommandPrompt:
1. Restart your computer. During the start process, repeatedly press F8until Windows Advanced Boot Options appears. Select Safe Mode with CommandPrompt and press Enter.
2. When you get into the Command Prompt window, type cd restore and pressEnter. Then type rstrui.exe and press Enter. Then you will launch theSystem Restore wizard and you can follow the wizard to complete restore process.
Restore Windows 7 with AOMEI Backupper.exe
AOMEI Backupper Professional is trustablebackup and restore software. It enables you to backup and restore the system either fromgraphic user interface or command line. The best part is you can restore system todissimilar hardware using the Universal Restore feature. Besides,it supports both 32 bit and 64 bit of Windows 10/8.1/8/7/Vista/XP.
Some requiredparameters:
● {/r}: restore the backup of system, disk, partition or dynamicvolume.
● {/t} {system | disk | part}: specify restore type.
● {/s}{D:my backupmybackup.adi | 192.168.1.1.my backupmy backup.adi}: specify the path of the imagefile.
● {/x}: specify universal restore to restore system to dissimilar hardware. It hasto be used with '/t system' and '/t disk'.
AOMEI Backupper restore is based on AOMEI Backupper backup. That is to say, if you want toperform system restore with AOMEI Backupper, you must create a system imagebackup by AOMEI Backupper in advance. To make the restore process smooth, you cancheck if system image backup is intact and without error by using the CheckImage feature.
Let's see the detailed steps to run system restore from Command Prompt in Windows 7 withAOMEI Backupper.
Step 1. Click 'Start' and type CMD to open the Command Prompt. Right click 'cmd'and select 'Run as administrator'.
Step 2. Navigate to AOMEI Backupper installation directory by typing the following commandand press Enter:
cd [installation path of AOMEI Backupper] (e.g., cd C:Program Files(x86)AOMEI Backupper)
Step 3. Type the following command and press Enter to start restore:
AMBackup /r /t [backup type] /s '[backup location path]' /d [destinationlocation]
For example:
① To restore the system image 'systembackup1.adi' saved in J:systembackup to disk 1. Thecommand should be: AMBackup /r /t system /s 'J:system backupsystembackup1.adi' /d 1.
② To restore the system image 'systembackup1.adi' saved in D:system backup to partition 0 ondisk 0 and perform universal restore. The command should be: AMBackup /r /t system /s 'D:systembackupsystembackup1.adi' /d 0:0 /x.
Notes:
● To run systemrestore when Windows fails to boot, you should create bootable media with AOMEI Backupper toboot your machine. It will bring you to the main interface of AOMEI Backupper. You can openCommand Prompt from Tools > Windows shell command andthen type the commands mentioned above to perform system restore.
● If you run thecommands under Windows PE, the drive letters might change.
Restore with AOMEI Backupper GUI
If there is nothing wrong with your Windows 7, you just want to restore it to a specificpoint to uninstall some programs or migrate system to another disk, like SSD or somethingalike. You do not have to run system restore from Command Prompt in Windows 7, you can alsocarry out the operations by directly launch this software's graphic user interface inWindows:
Click Restore and Select Task > Choose the system backuptask from the list > Select to restore the entire system or a partition > (Optional)Choose a destination path to restore the system image to > Click StartRestore. It is quite easy and you can make it with only a few clicks.

-->This article describes the switch options that you can use to modify Windows startup.
Original product version: Windows 10 – all editions, Windows Server 2012 R2
Original KB number: 833721
Summary
You can add many different switches to the Boot.ini file that will modify the way that Microsoft Windows XP or Microsoft Windows Server 2003 start.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
102873 Boot.ini and ARC path naming conventions and usage
More information
You can add the following switches to the Boot.ini file.
Note
These switches apply to Microsoft Windows XP and to Microsoft Windows Server 2003, unless otherwise specified.
/basevideo
The /basevideo switch forces the system into standard 640x480 16-color VGA mode by using a video driver that is compatible with any video adapter. This switch permits the system to load if you selected the wrong video resolution or refresh rate. Use this switch in conjunction with the /sos switch. If you install a new video driver, and it does not work correctly, you can use this parameter to start the operating system. You can then remove, update, or roll back the problem video driver.
/baudrate=number
This switch sets the baud rate of the debug port that is used for kernel debugging. For example, type /baudrate=9600. The default baud rate is 9600 kilobits per second (Kbps) if a modem is attached. The default baud rate is 115,200 Kbps for a null-modem cable. 9,600 is the normal rate for remote debugging over a modem. If this switch is in the Boot.ini file, the /debug switch is automatically enabled.
For more information about modem configuration, click the following article number to view the article in the Microsoft Knowledge Base:
148954 How to set up a remote debug session using a modem
For more information about null modem configuration, click the following article number to view the article in the Microsoft Knowledge Base:
151981 How to set up a remote debug session using a null modem cable
/crashdebug
This switch loads the kernel debugger when you start the operating system. The switch remains inactive until a Stop message error occurs. /crashdebug is useful if you experience random kernel errors. With this switch, you can use the COM port for normal operations while Windows is running. If Windows crashes, the switch converts the port to a debug port. (This action turns on remote debugging.)
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
151981 How to set up a remote debug session using a null modem cable
/debug
This switch turns on the kernel debugger when you start Windows. The switch can be activated at any time by a host debugger that is connected to the computer, if you want to turn on live remote debugging of a Windows system through the COM ports. Unlike the /crashdebug switch, /debug uses the COM port whether you are debugging or not. Use this switch when you are debugging problems that are regularly reproducible.
For more information about remote debugging, click the following article number to view the article in the Microsoft Knowledge Base:
121543 Setting up for remote debugging
/debugport=comnumber
This switch specifies the communications port to use for the debug port, where number is the communications port, such as COM1, that you want to use. By default, /debugport uses COM2 if it exists. Otherwise, the switch uses COM1. If you include this switch in the Boot.ini file, the /debug switch becomes active.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
151981 How to set up a remote debug session using a null modem cable
/maxmem=number
This switch specifies the amount of RAM, in bytes, that Windows can use. For example, if you want Windows to use less than 64 MB of memory, use the /maxmem=64switch.
However, the /maxmem switch does not account for memory holes. Therefore, we recommend that you use the /burnmemory switch instead. The /burnmemory switch accounts for memory holes.
For example, if you use the /Maxmem=64 switch, and the system requires 64 MB of memory to load, there may not actually be 64-MB available to the system because of a memory hole. In this scenario, Windows would not start.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
108393 MAXMEM option in Windows NT Boot.ini file
/noguiboot
This switch disables the bitmap that displays the progress bar for Windows startup. (The progress bar appears just before the logon prompt.)
/nodebug
This switch turns off debugging. This scenario can cause a Stop error if a program has a debug hardcoded breakpoint in its software.
/numproc=number
This switch sets the number of processors that Windows will run at startup. With this switch, you can force a multiprocessor system to use only the quantity of processors (number) that you specify. This switch can help you troubleshoot performance problems and defective CPUs.
/pcilock
For x86-based systems, this switch stops the operating system from dynamically assigning hardware input, hardware output, and interrupt request resources to Peripheral Connect Interface (PCI) devices. With this switch, the BIOS configures the devices.
/fastdetect:comnumber
This switch turns off serial and bus mouse detection in the Ntdetect.com file for the specified port. Use this switch if you have a component other than a mouse that is attached to a serial port during the startup process. For example, type /fastdetect:com number, where number is the number of the serial port. Ports may be separated with commas to turn off more than one port. If you use /fastdetect, and you do not specify a communications port, serial mouse detection is turned off on all communications ports.
Note
In earlier versions of Windows, including Windows NT 4.0, this switch was named /noserialmice.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
131976 How to disable detection of devices on serial ports
/sos
The /sos switch displays the device driver names while they are being loaded. By default, the Windows Loader screen only echoes progress dots. Use this switch with the /basevideo switch to determine the driver that is triggering a failure.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
99743 Purpose of the Boot.ini file in Windows 2000 or Windows NT
/PAE
Use the /PAE switch with the corresponding entry in Boot.ini to permit a computer that supports physical address extension (PAE) mode to start normally. In Safe Mode, the computer starts by using normal kernels, even if the /PAE switch is specified.
/HAL=filename
With this switch, you can define the actual hardware abstraction layer (HAL) that is loaded at startup. For example, type /HAL=halmps.dll to load the Halmps.dll in the System32 folder. This switch is useful to try out a different HAL before you rename the file to Hal.dll. This switch is also useful when you want to try to switch between starting in multiprocessor mode and starting in single processor mode. To do this, use this switch with the /kernel switch.
/kernel=filename
With this switch, you can define the actual kernel that is loaded at startup. For example, type /kernel=ntkrnlmp.exe to load the Ntkrnlmp.exe file in the System32 folder. With this switch, you can switch between a debug-enabled kernel that is full of debugging code and a regular kernel.
/bootlog
This switch turns on boot logging to a file that is named systemroot Ntbtlog.txt. For more information about boot logging, see Windows Help.
/burnmemory=number
This switch specifies the amount of memory, in megabytes, that Windows cannot use. Use this parameter to confirm a performance problem or other problems that are related to RAM depletion. For example, type /burnmemory=128 to reduce the physical memory that is available to Windows by 128 MB.
/3GB
This switch forces x86-based systems to allocate 3 GB of virtual address space to programs and 1 GB to the kernel and to executive components. A program must be designed to take advantage of the additional memory address space. With this switch, user mode programs can access 3 GB of memory instead of the usual 2 GB that Windows allocates to user mode programs. The switch moves the starting point of kernel memory to 3 GB. Some configurations of Microsoft Exchange Server 2003 and Microsoft Windows Server 2003 may require this switch.

/safeboot: parameter
This switch causes Windows to start in Safe Mode. This switch uses the following parameters:
- minimal
- network
- safeboot: minimal(alternateshell)
- DS Restore Mode (for Windows Server 2003 Domain Controllers only)
You can combine other Boot.ini parameters with /safeboot: parameter. The following examples illustrate the parameters that are in effect when you select a Safe Mode option from the startup recovery menu.
- Safe Mode with Networking
/safeboot: minimal /sos /bootlog /noguiboot - Safe Mode with Networking
/safeboot: network /sos /bootlog /noguiboot - Safe Mode with Command Prompt
/safeboot: minimal(alternateshell) /sos /bootlog /noguiboot - Windows in Directory Services Restore Mode
(This switch starts only on domain controllers.)/safeboot: disrepair /sos
Note
The /sos, /bootlog, and /noguiboot switches are not required with any one of these settings, but the switches can help with troubleshooting. These switches are included if you press F8 and then select one of the modes.
/userva
Use this switch to customize the amount of memory that is allocated to processes when you use the /3GB switch. This switch permits more page table entry (PTE) kernel memory but still maintains almost 3 GB of process memory space.
Note
Microsoft Product Support Services strongly recommends using a range of memory for the /USERVA switch that lies within the range of 2900-3030. This range is wide enough to provide a large enough pool of system page table entries for all currently observed issues. Usually a setting of /userva=2900 will provide close to the maximum available number of system page table entries possible.

Use this switch to turn on Emergency Management Services (EMS) on a Windows Server 2003, Enterprise Edition-based computer. For additional information about EMS, search on 'Emergency Management Services' in Windows Help and Support.
To turn on EMS by editing the Boot.ini on an x86-based computer, edit both the [boot loader] section and the [operating systems] section of the Boot.ini file. To do this, configure the following entries:
Under [boot loader], add one of the following required statements:
In this statement, replace x with one of the following COM port numbers:
1
2
3
4
This statement permits the computer BIOS to determine the COM port to use for EMS.
Under [boot loader], add the following option statement:
Replace baudrate with one of the following values:
9600
19200
57600
115200
By default, EMS uses the 9600 Kbps baud rate setting.
Under [operating systems], add the
/redirectoption to the operating system entry that you want to configure to use EMS. The following example illustrates the use of these switches:
/channel
Use this switch together with the /debug switch and the /debugport switch to configure Windows to send debug information over an Institute of Electrical and Electronics Engineers, Inc. (IEEE) 1394 port. To support debugging over a 1394 port, both computers must be running Microsoft Windows XP or later. The 1394 port has a maximum number of 63 independent communications channels that are numbered 0 through 62. Different hardware implementations support a different number of channels across one bus. Windows XP has a limit of four destination computers. However, this limitation is removed in Windows Server 2003. To perform debugging, select a common channel number to use on both the computer that the debugger runs on, which is also known as the host computer, and the computer that you want to debug, which is also known as the destination computer. You can use any number from 1 to 62.
Configure the destination computer
Edit the Boot.ini file to add the
/CHANNEL= xoption to the operating system entry that you have configured for debugging. Replace x with the channel number that you want to use. For example, configure the [operating systems] area of the Boot.ini file to look similar to the following:Plug the 1394 cable in one of the 1394 ports.
Disable the 1394 host controller on the destination computer. To do this, start Device Manager, right-click the device, and then click Disable.
Restart the computer.
Configure the host computer
Plug the 1394 cable in one of the 1394 ports.
Install the kernel debugger binary files.
Start a command prompt. Press enter after you type each of the following commands:
Move to the folder where you installed the kernel debugger, and then type the command: kd.exe.
Edit Boot Options Windows 7 Noexecute Optin Factory Reset Key
When you first start the debugger, a 1394 virtual driver is installed. This driver permits the debugger to communicate with the destination computer. You must be logged on with administrator rights for this driver installation to complete successfully.
