BOOT PARTITION LOCKED OR MISSING ON COMMAND PROMPT

[Cshks2208]

Computer was bought at Christmas. Unfortunately, it’s crashed I’ve tried to do a repair and recovery.

When in the command prompt it states there is no partition on this disk to show”

Can you please advise what I should now do.

Hi

Boot partition missing?  Perhaps an F11 would work?

Have you made a Recovery Media, 16 Gb USB stick?

F11, WILL WIPE YOUR DATA, press repeatedly at power on.

How are you getting to the Command Prompt?

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD

If in doubt please ask.

Thank you for your reply. I did appreciate this.

I am now trying to re install Windows 10 after the laptop crashed I got to the part where I’m trying to create partitions when I get the following message:

Diskpart has encountered a error: Data error.
(Cyclic Redundancy Error)
See the System Event Log: For more information.

If you can help me with this problem. I would be very grateful as I don’t know where to go from here.

Hi

It is possible that the crash has corrupted part of the Recovery area.

You may be able to do a Repair/Rebuild/Recovery/Re-Install with some of the info below...

This First part only works when a valid Recovery Partition is enabled.

If it displays an error message then move onto the Second Part:-
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.

Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.

Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

Second Part:-
This may require another PC. Find and Download your .iso from…
(You will need a NON_OEM key for W7);
W8.x and W10 should activate automagically from their embedded licence key.
https://www.microsoft.com/en-us/software-download/windows7
https://www.microsoft.com/en-us/software-download/windows8
https://www.microsoft.com/en-us/software-download/windows10

For when it’s a NON MS OS ( iOS / Linux ) creating the install media.
www.microsoft.com/en-us/software-download/windows10ISO
Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

Even though it has NO actual HP software/drivers included, you may be able to
XCOPY the C:\Users\* area onto a ‘large’ USB stick, via the Command Prompt.

You’ll need to try various drive letters; D:..-..Z: until it’s matched - could be G; mine’s S:

C:\>XCOPY C:\Users\* S:\ /e /i /h (then files like those 3 listed below get copied over)

C:\Users\desktop.ini
C:\Users\All Users\agent.1509128044.bdinstall.bin
C:\Users\All Users\HP Deskjet 2540 series\Help\flash\zoom.swf

Then you can try System Recovery Options / Advanced Options shown in the screenshots.

NB:- W7 Try running a Startup Repair more than once for a full fix.
NB: - W10 Begin with the Automatic Repair, then Startup Settings etc.

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD
