Laptop will not boot

[sailon]

I have an older pavilion laptop that was bricked by the latest windows update.  The BIOS tests all run successfully and it the SSDs/NVMe are good but the boot just hangs/spins at the boot screen. BIOS is up to date and I can bring up a bootable USB (Win/PE or a copy of partition magic - Linux).  Linux can see the SSD volumes but windows can’t.  Any way to bring back the partitions and MBR.?

Hi @sailon,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Pavilion laptop hangs at the Windows boot screen after an update, BIOS diagnostics pass, Linux can see the SSD partitions, but Windows recovery tools cannot. Let’s go through a few steps to check what could be causing this.

Confirm the disk layout (MBR vs GPT) from recovery media
Boot into Windows Recovery Command Prompt from your Windows USB.
Run:

diskpart

list disk

select disk 0

list volume
This confirms whether Windows still sees the EFI/System partition and OS partition.

Repair the Windows boot loader
If the disk appears in DiskPart, run these commands from Command Prompt:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These rebuild boot records that may have been corrupted during the update.

Rebuild the EFI boot files (common fix for UEFI systems)
If this Pavilion uses UEFI (most do), run:

diskpart
list vol
(select the EFI partition — usually FAT32, ~100–300 MB)
assign letter=S
exit

Then run:
bcdboot C:\Windows /s S: /f UEFI

This recreates the Windows Boot Manager.

Run offline disk repair
Still in recovery Command Prompt:

chkdsk C: /f /r

File-system corruption after updates can cause Windows to hang during boot.

Repair the Windows image offline
If the Windows partition is visible:

DISM /Image:C:\ /Cleanup-Image /RestoreHealth
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

This repairs system files without booting into Windows.

I hope this helps.

Thanks much for responding!  I was about to give up.  So the only ways I can currently get into the laptop is booting from a USB either in Linux or Hiren’s.  The later is GPT.  But it only shows the USB as drive 0 and no other partitions. I’ve tried using the HP recommended RST drivers but no luck.  Linux does see the SSD drives and was about to explore whether Linux could repair the Windows partition.  

How do I get access to the Windows Recovery Command Prompt?  Hirens (Win 10 /PE) in addition to Disk Management. I guess I could dig into the MCT but wasn’t sure how to get my license #.

Ok, sorry googled to the answer - since I can’t access any of the windows SSD drives I can’t get to a copy of the Windows Recovery Command Prompt utility. Is there any way I could get a copy from another computer (or the web)?

Hi @sailon,

Thank you for the response.

I understand your HP Pavilion cannot boot into Windows, Linux can see the SSD, but Windows-based tools like Hiren’s or WinPE cannot see the internal drive, and you’re trying to access the Windows Recovery Command Prompt. Let’s go through a safe way to proceed.

Create official Windows recovery media
You can create Windows recovery media from any working computer, you do not need access to the broken laptop.
Download the Windows Media Creation Tool from Microsoft, insert an 8 GB or larger USB drive, and create a Windows installation USB.

Boot into Windows Recovery Command Prompt
Insert the Windows USB into the Pavilion and power it on.
Press F9 for the boot menu and select the USB drive.
When the Windows setup screen appears, choose Repair your computer → Troubleshoot → Advanced options → Command Prompt.

Why Windows tools cannot see the SSD
Since Linux can see the SSD but Windows tools cannot, the most likely cause is the Intel RST/VMD storage controller driver not being loaded in WinPE.
This is common on Pavilion systems using NVMe with Intel Rapid Storage Technology (RST).

Load the storage driver manually in recovery
In the Windows Recovery Command Prompt, you can load the storage driver from a USB folder containing the Intel RST (VMD) driver.
Once the driver loads, DiskPart should detect the SSD and partitions.

Confirm disk detection
After loading the driver, run:
diskpart
list disk
list volume

You should then see the internal SSD instead of only the USB drive.

About your Windows license
You do not need your Windows license key.
On HP systems, Windows activation is stored in the system firmware (digital license) and will activate automatically after reinstall or repair.

Important note:
Because:

BIOS diagnostics pass

Linux can see the SSD

Windows recovery tools cannot see the drive

The issue appeared after a Windows update

This strongly indicates a storage-controller driver visibility issue (Intel RST/VMD) rather than a failed SSD or lost partitions. Your Windows data is likely still intact.

I hope this helps.

Really appreciate your help with this and believe we’re getting closer although not quite there yet. So I made the W11 MCT and rebooted the dead laptop from the USB and I’m at the point in your previous: “Troubleshoot → Advanced options → Command Prompt.”.    The command prompt needs the driver as it only  seems to see the X: drive and still no SSD drives (ie C). I do have another W11 laptop that is still operable. How do I proceed and load the driver?

[sailon]

BTW:   I can see drive E:  ( in addition to X:)  And if I put a different USB drive in a different port, it is visible as drive F:   So I downloaded sp111381.exe (the storage driver for RST w/o the firmware patches) and can see it on drive F:

[sailon]

Ugg… after searching and running around,  I’m finally getting the message. So I thought that the “recovery command prompt” was a utility and I realized that you were referring to walking through the blue screens at boot and getting to the command interpreter.  Ok, now that we’re synced, from the command line running disk part shows me 3 disks (disk 0 is 4xxGB, disk 1 is 27G and disk 2 is 28G) and all are online!  Disk 0 has 4 partitions the others just 1 partition (those are marked as primary).   Disk 0 must be my data and OS. The partitions on Drive 0 are marked 1:system (269M) 2:Reserved (16M), 3:Primary (474G), 4:Recovery(1062M).    I really don’t want to loose my OS and data but would like to make the laptop bootable again!  So which disk/partition needs to be repaired and made bootable (using the bootrec. commands you listed earlier)?

[sailon]

Ok found the command appropriate for disk part, will attach the output. But I’m a little nervous and would appreciate the commands necessary to fix the bootrec.  What is the difference between volume and partition?  Is looks like volume 1 is FAT and the boot partition.  Do I need to select the volume/partition to run the bootrec  fixmbr, fixboot, scanos, rerebuildbcd in order to avoid overwriting my OS or data.
