Windows 10: After running `bootrec /fixmbr`, I am stuck at `reboot and select proper boot device...`

Hello,My Windows 10 was stuck at the `Startup Repair blue page` when starting up my Windows like below: So I tried to follow this to run the commands using `bootrec` executable to fix it. I ran `bootrec /fixmbr` first but then when I ran `bootrec /FixBoot`, it gave me permission denied. So I just decided to restart and see what happens. However, when my laptop restarted, I landed on the BIOS page, sth like the picture below. On this BIOS page, I tried to reset to default and then save changes. Now after my laptop restarts it always show me the page when it says:```reboot and select proper boo

:)

 

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.

 

Win 10 to Win 11 upgrade failed; "reboot & select proper boot device ..."

Hello.

If you see the message "reboot and select proper boot device" the bootloader is probably missing. To fix:

1. Put the Windows 11 media, and then start the computer.
   
2. Select a language, a time, a currency, a keyboard, or an input method, and then click Next.
   
3. Click Repair your computer.
   
4. Click Troubleshooting > Advanced > Command Prompt
   
5. Type:
   

• bootrec /fixboot
  
• bootrec /fixmbr
  
• bootrec /rebuildbcd
  

6. Reboot your PC

If any of the commands above fail, type:

• bootsect /nt60 SYS /mbr /force
  

If that does not help you can export and delete the BCD store and then rebuild it again.

In Command Prompt type:

• bcdedit /export C:\BCD
  
• cd /d C:\Boot
  
• attrib bcd -h -r -s
  
• ren bcd bcd.old
  
• bootrec /rebuildbcd
  

Best regards.

 

Reboot and Select Proper Boot Device...after reboot?

Hello all. Getting a little frustrated here. A couple of weeks ago we had a user come in on a Monday morning to find that her pc was displaying the classic message "Reboot and select proper boot device...". Tried popping in a windows disk and fixing the MBR, no luck. Ended up reinstalling windows and her few programs back on it. All was good after this. For about a day. She came in the next day to find the same message. So at that point we decided that more than likely the drive was bad even though oddly enough it tested out fine. It was a Corsair 60gb SSD.

Last week we swapped that Corsair with a 64gb Crucial SSD and installed Windows. We then created a backup image of that drive. All was good until Thursday when her power strip that the PC was plugged into got tripped. Start up the computer for find "Reboot and select proper boot device..." message. So, apply the backed up image to the SSD since repairing the MBR didn't work.

Now this morning she comes in and the PC is running fine. Attempts to open Microsoft Word and she gets a pop-up stating there isn't enough disk space. So, she then restarts and upon booting back up gets "Reboot and select proper boot device..."

Any ideas what is causing this? Is it something with the mobo or do I just have horrible luck and replaced the bad SSD with another bad SSD?
