Unlock bitlocker on Hard drive

[CCP2026]

My brand new HP Pro Tower 290 G9 i312100 8GB/512GB PC  hard disk drive is locked by bitlocker, i however have the key but i mistakenly wipe the OS on the PC.

I have no backup as well .The initial error was stopcode unmountable boot volume before bitlocker locked the drive.

Please i sincerely need help,since 29/06/2026 toll date i have not slept well.

Thank you in advance and God blessings upon all of us here.

To obtain a (bitlocker) recovery key, log into the Microsoft account you used to activate windows. Find your HP device and make a note of the recovery key. Note that characters from this set: ilL1oO0D8B5S are easily mixed up depending on the font used.

You can also disable or enable bitlocker using windows powershell as explained here.

a bitlocker key will be useless after a os eraseure/format of the drive has been done as the data no longer exists

3rd party professional data recover services will also most likely be unable to help as the data on the drive was encrypted before drive eraseure but you can ask them.

do note that data recovery is not cheap or guarenteed,

payment is required for the attempt at data recovery
