Once Bitlocker key is entered, my tablet tries to diagnose and after 30 minutes restarts and asks for the bitlock again. How can I unlock my tablet and gain access?

After I enter in my bitlocker key, my computer tries to diagnose the problem. Next it pulls up a window with a "couldnt connect to the network. Keep your device on and well look for solutions again in : 30 minutes (starts at 30 minutes and winds down).

At the end of 30 minutes, my surface pro restarts and goes back in to the same loop of requesting my bitlocker key, tries to diagnose and then claims unable to connect to the network. Does anyone have a workaround to this problem? Need to re-gain access to my surface pro.

Dear @Lechner, Rob,

Thank you for posting your question in the Microsoft Q&A forum.

We apologize for any inconvenience you may encounter when using our services/ products. Based on your description, kindly try these following steps:

Break the automatic repair loop (WinRE)

Enter the BitLocker key when asked > when “Diagnosing your PC” appears, press Power to interrupt and force Advanced options. If you only see the countdown page, let it finish once, then as soon as it reboots press Shift + F8 (or hold power 10s twice) to reach Choose an option.
Go to Troubleshoot > Advanced options > Command Prompt.
In the console, run:

bcdedit /set {default} recoveryenabled No
bcdedit /set {default} bootstatuspolicy IgnoreAllFailures

This stops Auto Repair from re‑triggering at boot and lets us see the real failure.
Restart > if it now boots normally, re‑enable recovery later:

bcdedit /set {default} recoveryenabled Yes
bcdedit /set {default} bootstatuspolicy DisplayAllFailures

Repair system files and disk

Go to Troubleshoot > Advanced options > Command Prompt

chkdsk C: /f /r
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
DISM /Image:C:\ /Cleanup-Image /RestoreHealth

Restart and test.

Rebuild the boot loader (BCD)

If the loop persists, still in Command Prompt:

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

If access is denied on /fixboot, run:

bcdboot C:\Windows /f UEFI

Restart.

Hi Huy-K,

Thanks a lot for reaching back out.

However, the solution that was suggested did not work and the bitlocker loop continues. Still unable to access my surface pro.

Would we be able to schedule a call and troubleshoot this live? Note I have a work computer and would be able to utilize in talking thru troubleshooting solutions.

Best,

Hi Huy-K,

I tried taking my devise to a local UbreakIFix store and also to a BestBuy to see if Geeksquad could resolve. Neither teams were able to resolve my issue and they recommended I reach out to get in touch with Microsoft. Can you share with me if there is a way for me to request a service ticket without having to get my company administrator involved? The issue I am having is with a personal surface pro device and I would prefer if we could manage this outside of my work contacts.

Can you share with me the best way to proceed? If needed, I am happy to mail my device to Microsoft (Texas offices). Looking to understand best path forward for this device.
