Lenovo T470s，win10能啟動但是start欄都亂碼，後來啟動要bitlock key，找到輸入啟動後，去除了bitlock，當時覺得解除bitlock似乎很快就完成了。然後似乎是刪掉了bitlock的key。
今天啟動發現又要bitlock key，怎麽辦？
F1進BIOS、啟動Windows安裝盤也不行，要求先解鎖bitlock

Use Windows installation media to open up the command line, then execute the diskpart command and delete the partition, e.g.: list disk, select disk 0 or any other identifying the correct disk, list partition, select partition 1, or the encrypted one , in case there are multiple partitions, then delete partition override.
