Question 382Question →

A technician is resolving a Windows startup failure caused by a corrupted Boot Configuration Data (BCD) store. Operating in the Windows Recovery Environment (WinRE) Command Prompt, the technician attempts to run `bootrec /rebuildbcd`, but the command cannot replace the existing store because the BCD file remains locked and marked as system-protected. Place the remaining steps required to unlock, replace, and successfully rebuild the BCD store in the correct sequential order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with removing the file attributes using `attrib`, followed by renaming the corrupted BCD file using `ren`, re-executing `bootrec /rebuildbcd` to regenerate the boot store, and finally confirming the addition of the OS installation when prompted.
When repairing BCD store corruption, `bootrec /rebuildbcd` may fail if the existing BCD file is locked or damaged. The proper recovery procedure requires removing the system, hidden, and read-only attributes from `c:\boot\bcd` using `attrib -h -r -s`. Next, renaming the file with `ren c:\boot\bcd bcd.old` clears the path. Running `bootrec /rebuildbcd` then initializes a new configuration store, and entering `Y` at the prompt adds the operating system to the clean BCD file.

Step-by-Step Solution

1
Clear system file locks and attributes.
File attributes (-h -r -s) are removed from `c:\boot\bcd` so administrative commands can modify it.
Windows protects boot configuration files with System, Read-only, and Hidden attributes, preventing them from being renamed or overwritten while protected.
2
Rename the existing corrupted BCD store.
The file `c:\boot\bcd` is renamed to `bcd.old`.
`bootrec /rebuildbcd` will fail to create a new file if an existing file with the same name exists at that directory path.
3
Initiate the boot reconstruction utility.
The utility scans all connected drives for Windows installations and prompts to add discovered OS installations.
Now that the corrupted file path is clear, running the rebuild command allows the installer to initialize a clean boot database.
4
Confirm adding the detected OS to the new boot store.
The Windows boot manager entry is successfully written to the new BCD store.
User confirmation is required by `bootrec` to finalize adding identified OS installations to the newly constructed database.

Show answer & explanation

Answer

The correct order begins with disconnecting external power and shutting down the OS, followed by removing the chassis cover, disconnecting the internal battery, removing the old SODIMM at a 45-degree angle after releasing the clips, and finally inserting the new SODIMM at an angle and locking it down.
The proper sequence follows standard CompTIA hardware maintenance protocols: first isolate external AC power and shut down the device, remove the lower enclosure, disconnect the internal battery to eliminate residual voltage, release and tilt the existing SODIMM module out of its socket, and insert the new SODIMM at a 45-degree angle before locking it flat into the retaining latches.

Step-by-Step Solution

1
Isolate system power source
System powered off completely with no external AC connection
Prevents data corruption and electrical hazards during physical disassembly.
2
Gain physical access to internal chassis
Bottom enclosure panel removed
Exposes motherboard components and RAM expansion slots.
3
Isolate internal power supply
Internal battery cable disconnected from system board header
Eliminates lingering standby voltage that could cause short circuits while handling components.
4
Remove existing SODIMM memory module
Retaining clips opened and module unseated at 45 degrees
Allows memory card extraction without placing strain on motherboard socket pins.
5
Install replacement SODIMM memory module
New module seated in slot at 45-degree tilt and pressed flat until locked
Ensures complete pin contact alignment and secure mechanical retention.

A field technician needs to replace a damaged motherboard inside a modern enterprise laptop. To comply with standard hardware safety practices and prevent component damage, in what order should the technician perform the following disassembly steps?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The proper technician workflow sequence is: 1) Disconnect AC power and shut down, 2) Attach ESD wrist strap, 3) Remove bottom chassis access panel, 4) Disconnect the main internal battery cable, 5) Disconnect internal ribbon cables and remove motherboard mounting screws.
The correct service procedure begins by cutting external AC power and shutting down the system, followed immediately by establishing anti-static ESD grounding. Once grounded, the technician removes the lower base cover to reveal internal components. Before detaching sensitive peripheral ribbons (such as the display panel cable), the internal battery MUST be unplugged to de-energize standby power rails. Finally, with power completely severed, peripheral ribbon cables and mounting screws are removed to release the motherboard.

Step-by-Step Solution

1
Isolate external power sources
System powered down with no external power draw.
Prevents electrical surges or data loss during hardware servicing.
2
Apply ESD personal protection
Technician grounded to equalized potential.
Protects sensitive microelectronics from electrostatic discharge damage before contacting internal components.
3
Remove lower chassis access cover
Internal system components exposed.
Provides physical access to internal motherboard connections.
4
Unplug internal main battery connection
System board completely de-energized.
Modern laptops keep standby power active on motherboard traces even when powered off; removing battery power prevents short circuits when detaching display/ribbon cables.
5
Detach peripheral data ribbons and extract retaining screws
Motherboard uncoupled from chassis.
Ensures no trace tearing or cable connector damage occurs during board extraction.
