Windows 10: I need to reinstall Windows 11 on a drive locked by Bitlocker, without key

Hi I've downloaded the Windows 11 Installation Media the option that creates the USB for you and booted to it, but I'm unable to install Windows. If I select 'Install Now' -> Custom remove files no drive is found in the Drive options window, and Repair just sends me back to the dead ends related to not having the Bitlocker key. It's an SSD.How can I wipe the drive and install Windows?ThanksAl

:)

 

Windows 8.1 PRO unable to unlock Bitlocked drive

As you can see BitLocker Option is not highlighted for selection. It's like Windows does not even recognize this drive as a locked drive. And this drive does contain lot of Data.

 

Is there a way to unlock HDD Drive that's locked by Bitlocker without key?

Hello, after updating my laptop from Windows 10 to Windows 11 HDD drive (D is locked by Bitlocker.
Previously i didn't had Microsoft account, i used only my gmail account. I didn't use Bitlocker at all.

While updating to windows 11 i formatted only the C: drive, where Windows 10 was installed.
I created new mail and Microsoft account at the first start of Windows 11. After finishing the setup I saw that D drive is Locked, and to unlock it i need to have 48 digit key, that i don't have.
I didn't save any file anywhere, i didn't prepared no usb key, i didn't knew this bitlocker thing was active in my laptop at all.

Now when I access my new Microsoft account i see key for Bitlocker only for Drive C. (that helped me to disable bitlocker for Drive C).
Drive D is not in the list.

I tried to access this key check page with my gmail account, and I couldn't login (because it's not a microsoft account).
Also i checked cmd commands to see full Key ID that Bitlocker requires but it's not password to unlock.
I tried to disable SecurityBoot to see if this will show password, but still only the Key ID is shown.

After updating Windows i had to update BIOS too.

Now in BIOS i can see and save TPM keys, but none of them have same Key ID as bitlocker requires (this may be due to newer version of bios). Currently windows not allows me to roll back to previous BIOS version, because it's not supported.

I'm not even sure if TPM keys would help at all, to be honest.

As a final detail, i would add that the reason why i updated Windows to 11 and BIOS, is because latest windows update caused my graphic card to drop it's frequency for no reason at all. Temperature was 65 to 69 degrees max.
This caused games and video files to "stutter" or lag noticeably and no graphic card driver reinstall helped. I'm fixing this update aftermath for a week now, and after D: drive lock, I'm not able to work. I need data from that drive, formatting it is not an option for me.

Is there a way to request the key by only having Key ID?
How can i unlock my HDD?

Please help.
