Windows 10 boot up displays Remove disks or other media Press any key to restart

My UEFI (actually motherboard maker actually calls it "UEFI BIOS") has three relevant options for Boot Override:

1. IntelSSD

2. USBRecoveryStick

3. UEFI:USBRecoveryStick

(Yes, 2 & 3 are the same USB stick, but I don't know how they are different)

When I boot to each of these respective options using the UEFI Boot Override, I get:

1. The error I originally reported: Remove disks or other media Press any key to restart

2. Boots to full screen width Recovery Environment, where I can access the BitLocker disks just fine after providing the key files or even typing in the key.

3. Gives me an error 0xc0000007 and says there is a problem with \EFI\Microsoft\Boot\BCD.

I'm looking into whether BCDBoot is part of the solution. My system has UEFI (not BIOS), but the IntelSSD is MBR. Some things I've read also suggest that the System Partition has to be the active partition when using BitLocker, not the Windows partition.

 

Insert boot media in selected boot device and press a key

HI Dave and thanks for writing. Removable media? I'm not sure exactly what that means. But, I do have a keyboard and mouse that were connected to the computer thru a USB plug-in. I removed the plug and tried to start it up with the same result: a black screen
that says, "Insert boot media in selected boot device and press a key."

 

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.
