Missing operating system when i didn't encrypt that drive

[Peter Pan]

Check for solution at the bottom

Hi , i have 2 drives into my computer
1 ssd C with windows on it.
1 hdd D
I used the non system encryption (second option) on set up to encrypt my D drive.
After 8 hours the encryption completed i went and opened a file i had in there and it worked .
I restarted my computer and now i am getting an error Missing operating system when i did not encrypt C .

What can i do to fix this?

I already checked bios and C is the first boot option.

Update : If i remove D which is encrypted and leave the ssd where windows are in there i get the following error "reboot and select proper boot device or insert boot media device and press a key.

Bios recognise the ssd just fine and it's the first option .

Still can't get access to my pc : (

Update3: If i do a clean windows 10 install of my C the other drive wont be affected right?

I am start losing my sh*t here . Why did this even happen : (.

Before you do anything too drastic just yet, you might try chilling the SSD. You said that the encryption of your D drive took about 8 hours. That process may have generated a fair amount of heat, which may have radiated to the SSD if it is in close proximity to the hot D drive. A couple of weeks ago I had an SSD that the BIOS wasn't recognizing (your situation is apparently a bit different). I solved the issue by removing the SSD and chilling it with a gel pack from my freezer. After about 5 minutes of direct contact with the gel pack, I popped it back into the computer and it's been functioning fine ever since. Heat can produce erratic problems.

It is possible that the Windows OS boot files are located on your D drive instead of the C drive. Hence the original error you received of Missing Operating System.

If true, can you install the D drive into another PC with the same version of VeraCrypt to decrypt the drive?

You can Google "Windows Missing Operating System" to read other ideas to try to fix you system. However, I would recommend removing the D drive to prevent overwriting your D drive.

Update3: If i do a clean windows 10 install of my C the other drive wont be affected right?

I would physically remove the HDD from the PC due to Windows OS installation has a history of initializing drives that are considered not formatted.

Gary Marks thanks for the info even though i doubt that's the problem . I will keep that in mind to future reference in my tech life .

Enigma ,thanks for the advice i appreciate that. And no but there is no way the files are on D instead of C.

Is there any other though u may have of why did this problem occured to me ?

Thank you.

Enigma ,thanks for the advice i appreciate that. And no but there is no way the files are on D instead of C.

Before your system was no longer able to boot, did you use the Disk Management to review that boot files are on the C drive instead of the D drive?

See the first post at the link below. Look at the "I Games" drive. See the System, Active? That is the boot files location that Windows is trying to find. For this user, the solution is the second to last post from Saltgrass. However, this solution worked due to the user was still able to boot their PC.

[Solved]
I was going to format my drive so i went ahead and mounted a clean iso of windows 10 which can be found here : https://thepiratebay.org/torrent/12176822/Microsoft_Windows_10_Home_and_Pro_x64_Clean_ISO
Before formating i though why not try to repair windows it may work . So
Boot , tried to do repair and maintain files but got driver was locked , please unlock the drive and try again. So i went ahead and clicked on another option it had " repair files" , did that and suddenly my pc booted normally.

To my mind it seems like windows couldn't locate the correct path for booting and repair fixed that.

Btw, when i was doing my restart before all this mess windows 10 did updates (not sure if it matters i am just mentioning it).

Thanks you kind stranger of the internet for your attention , you can mark add a [Solved] in the title.
