Windows 10: WINDOWS BOOT MANAGER STILL SHOWING HDD AS BOOT DEVICE

Hello there, I am having a very strange issue with my HP laptop, I purchased this laptop couple of years ago and few months back I decided to upgrade my laptop from HDD to SSD, so I purchased a NVMe gen4 SSD and to install new WINDOWS on SSD I disconnected my HDD and installed windows 11 on my SSD, Laptop worked perfectly fine for few months but now I noticed a very strange thing in my pc, i.e., tho my windows is installed in my SSD but in boot manager it still shows HDD as the boot device even I've tried resetting the HDD, next I tried to disconnect my HDD but as I do so my pc says "no boot d

:)

 

Boot device- insert proper boot device or insert boot media...

Hi,

Do you have something like Windows Boot Manager on the list...

This is what UEFI machines use as the boot selection for windows...

Do you have another option in the BIOS for "Which" HDD\SSD ?

A lot of times if you pick a HDD\SSD as the boot device it will use the HDD\SSD that is listed as the 1st HDD\SSD... The 1st HDD\SSD is selected with a different button, usually on the same screen...

You may find the Windows Boot Manager there...

 

UEFI boot options disappeared from BIOS; now getting reboot and select proper boot device

In short, I need to get the system/BIOS to allow UEFI booting of the SSD.

Computer started up today with default BIOS settings.

• Only SSD 1(Windows boot) and SSD 2 were listed in BIOS; HDD 1 and HDD 2 were not visible
• System would not boot. Gave the 'reboot and select proper boot device' message
• Boot menu has no UEFI/EFI (or Windows Boot Manager) entries anymore

I went into Partition Magic/Gparted and confirmed :

• All drives are still showing
• All drives' data is in tact [EFI volume/partition is still listed (and can be browsed/files accessible)]

Gparted print out (note dev/sda2 apparently that is normal behavior) :

/dev/sda1 (locked) EFI System Partition--Fat32--/media/sda1--100.00mb--46.81MiB--53.19MiB--boot,esp
/dev/sda2 (exclamation mark) Microsoft reserved partition--unknown file system--no mount point--128.00MiB--unused spaced--msftres
/dev/sda3 basic data partition--ntfs--/media/sda3--118.58GiB--70.78GiB--47.80GiB--msftdata
/dev/sda4--ntfs--/media/sda4--450.00MiB--327.71MiB--122.29MiB--hidden,diag



As I am able to boot Windows installation from USB, I tried the standard startup repair. It said it was not able to fix any problems.

Next I tried to repair the EFI with Diskpart in the shell:

• sel vol 1 (note that Diskpart states EFI partition is 'hidden')
• assign letter=z:
• cd /d z:\EFI\Microsoft\Boot\
• bootrec /fixboot
• bcdboot c:\Windows /l en-us /s vz /f ALL

It completed all tasks successfully. Unfortunately that did not work.

Other things I have tried :

• Removing CMOS battery and replacing with a new one - my HDD started showing up again after doing this.
• Using the old MBR commands(in hopes it would force the Windows startup repair to recognize and fix a problem)

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

• Loaded BIOS 'optimized'/defaults (the system did this already once before, hence why I am in this situation, though doing it manually seemed like an option worth trying. Note that after doing this and restarting the system, HDD's stopped showing again)
• Removed new CMOS battery and left it out of the system for thirty minutes
• Formatted EFI and msftres partitions, then rebuilt the EFI boot records

In summary, am looking to force the BIOS to see the EFI partition on the SSD boot drive, as it is not an option any longer.

 

Why is windows boot manager not showing up in my boot options?

I try to boot my computer and it says reboot and select proper boot device. When I go to my bios what usually shows windows boot manager along with my ssd and hdd isn’t there. Now it is only showing my ssd and hdd and neither are being able to boot.
