Boot failure after DiskCryptor encryption

I have recently encrypted two Acer W7 laptops for a client using DiskCryptor. The encrytion process ran OK, but then neither machine would boot up. They just came up with an error messages leading to "Windows Repair". The recovery bootloader disks won't work either, saying the passwords are incorrect.

I have successfully managed to decrypt both machines using a Boot CD which contains DiskCryptor, under. so I am back to square one.

Before encrypting the two client machines, I ran the exact same process on a test machine, also W7 and that worked fine.

Can anyone shed any light on this and suggest a way forward.

Thanks

Edited out the name of a CD that isn't allowed to be mentioned on this site.

These are two brand new machines, an Acer TravelMate P253 and an Acer TravelMate P273-MG, so there is no question of any previous encryption.

As for the error message, sorry I don't remember the exact details (as I've now decrypted both machines), but it basically says that something to the effect that Windows cannot start, possibly due to a recent hardware change; It says to insert the OS disk and then restart and select Repair Windows.

I am not aware of anything special about the boot manager; as I said these are brand new machines.

Update:  The test machine is an older MBR partition style machine, whereas the new client's machines are GPT partition style. From what I have gathered so far it appears that DiskCryptor does not work with GPT. So I am left with two choices:

1) Convert the GPT disks back to MBR (not ideal as it's essentially a backward step and would involve a lot of data backup/restore, system/OS re-installation and client software set up).

2) Find another (preferably free) disk encryption solution which does handle GPT.

Any thoughts or suggestions anyone?

McKnife, thanks for confirming it only works for MBR ("out of the box", whole disk encryption). I checked out your link, which I recognised as having seen before and I had decided it looked far too complicated and far too time consuming to implement.

David Johnson, at present the client machines are Windows 7 Pro (purchased as "downgraded from win 8.1 Pro" at client request). So the solution I propose to adopt is to use Anytime Upgrade to Windows 7 Ultimate (for which the client will have to pay) and use Bitlocker, as you suggest. Or might it be possible to revert to Win 8.1 Pro, at no cost, since that has Bitlocker included?
That you will have to discuss with the client

No further progress yet, as Client has postponed job for a couple of weeks. But I have one BIG question. Does Bitlocker work with GPT?

I've encrypted the SSD on my laptop and does not boot after encryption. Says {BootDevice Not Found / Please install an operating system on your hard disk. / Hard Disk - (3F0)}. What can I do to make it work or to decrypt.
Thank you !
Why not ask your own question? This one is old.
