![]() ![]() Malicious programs specifically designed to target hard drives on your PC can corrupt all your existing data. Due to the unavoidable nature of such occurrences, users remain at risk of losing partitions on their Windows devices. However, out-of-the-blue scenarios, including hard drive errors, could occur, leaving you with little to no chance of salvaging any of your files. Many computer devices by design are meant to last several years. There are various reasons why a partition may be lost or deleted on your PC running Windows 10. Reasons for Lost Partitions in Windows 10 Recovering deleted partitions in Windows 10 isn’t a tough row to hoe, as this article explains some of the best possible ways to go about it. While it’s exceptionally uncommon to lose a whole volume of files, the effects could be devastating if they include files that you find very useful. On the other hand, losing an entire partition can be more catastrophic and sophisticated to undo. It’s even worse if you are at a loss on how you can recover them. Deleting this XML file finally allowed us to encrypt the disks on this troublesome Lenovo laptop.Reading Time: 8 minutesIf you lose files on your Windows PC through accidental deletion or some unknown reason, the consequences could be truly disastrous. This is the result of an unreadable XML file in c:\windows\system32\recovery. Use the BitLocker Drive Preparation tool to prepare a new small partition: Bdehdcfg.exe –target defaultĪfter all the steps above, BitLocker still choked with the common “File not Found” error.Change the BIOS boot mode from BIOS to UEFI.Use mbr2gpt /convert /disk:0 to change the partioning scheme from MBR to GPT.Use bootrec /fixboot, bootrec /rebuildbcd and bootrec /scanos then bcdboot c:\windows /s D: to build a BCD copy boot files to the newly created 500Mb partition.Use diskpart to assign drive letter C: to the 500Mb partition.Use Minitool partition wizard to shift drive D: to the right and create a 500Mb partition in the free space left behind.These were the steps we took in order to solve the problem: ![]() However, due to the weird disk layout, mbr2gpt wouldn’t work out of the box (“mbr2gpt /validate /disk:0” failed). Microsoft provides the tool “mbr2gpt” for the purpose of changing the partitioning scheme on harddisks without data loss. The laptop in question was using BIOS boot mode with the MBR partitioning scheme – two extra challenges to overcome. ![]() This is due to the fact that when switching the BIOS to UEFI, Windows won’t boot unless the disk is partitioned with GPT. Disk partioning scheme has to be GPT (not MBR).BIOS boot mode has to be set to UEFI (not legacy/BIOS).In order for BitLocker to work, a few prerequisites have to be fulfilled: Instead, we set out to reshape the disk layout in order for BitLocker to agree to encrypt the disks. Reinstalling Windows would be the last resort, because this laptop was running a few pieces of special software that would be difficult to reinstall. Boot and Windows are located on separate disks The laptop had two physical disks and for some unknown reason, the boot partition sat on disk 1 whereas Windows was installed on disk 0. Most laptop disks got encrypted without a hitch, but one particular Lenovo laptop posed a tricky challenge due to its odd disk layout. The only tools at our disposal were Active Directory, PowerShell and Group Policies. Recently, we were asked to roll out BitLocker for a client with approximately 80 Windows 10 laptops of various brands and models on their network. The disk layout is difficult to fix, because the boot partition and the Windows partition sit on separate disks.The partioning scheme can’t be changed from MBR to GPT because Microsoft’s tool mbr2gpt says the disk layout is invalid.BitLocker can’t be enabled, because the hard disks are using the MBR partitioning scheme. ![]()
