Unable to recover my datas since Windows update

Hi!
I have crypted my system disk with VeraCryptm and it worked very well until windows 8 made its usual update. Usually, I decrypted my disk before windows forced me to restartm but this time it has gone faster than I.
Since this update, Windozs is not able to start anymore and my rescue disk from VeraCrypt does not work, I can only boot on usb disksm such as the Linux Mint I am using now!
So I have some urgent questions.
Do I have lost all my datas?
Is there some way to decrypt my (internal) disk from the Linux I boot with?
I wish someone could help me, I have all my stuffm private and professionnalm on this disk!
Please excuse my english, and thank you for any help you could give me

Sorry but I have forgotten some important things. I have tried to install Veracrypt on my portable Linux Mint and run "Auto-mount devices" with the password I used on my system drive, But Veracrypt answers that it cannot mount any device, I tried to type the password with qwerty and azerty style, with no success both,
I hope it could help,
Thank you again
When mounting the drive with VeraCrypt in Linux Mint, click the Options button. Try ticking the box "Mount partition using system encryption (preboot authentication)".
I don't know if that will work.
Thank you a lot! It worked!!
But (there is a "but"): since I can access to the files of the volume, Veracrypt does not propose me to decrypt the volume. Do you know a way to do it without data loss?
Thanks again!

Hi
My question was not precise enough,
The disk I try to decrypt is my system disk, on which I cannot boot since Windows did its update. Now, thank Dave, I can access the files, but still not boot on it, Does someone know a way to make my disk bootable since Veracrypt does not propose me to decrypt it?
Can I simply copy the whole files that are on the disk, format it, then copy it back to recover my Windows in function?
Please someone could help me? I cannot get access to my computer for many days because of Veracrypt.
May the following solution be possible? As my rescue disk does not work since the Windows update that caused mt problem, there may be a solution to update it?
For an easier comprehension, here is my situation
Hi Semar,
I'm not familiar with running VeraCrypt on Linux, and the options may not completely duplicate what's in the Windows version, but let's verify the procedure you're attempting. After you've mounted the system volume (without pre-boot authentication), you'll see that volume listed in the main VeraCrypt Window, correct? If you right-click on that mounted volume, that's where you should see a menu with the option to "Permanently Decrypt..." If not, do you have a WinPE image on a bootable thumbdrive? That way you could run the portable Windows version of VeraCrypt, and that might be an environment that's better suited to repairing/decrypting a full Windows system drive.
I'm guessing that this is all a result of Microsoft beginning to push out Windows 10 v2004 major upgrades, and VeraCrypt users may have their bootloaders screwed up in the middle of the upgrade process.
Thank you very much!
I do not have a live Windows system, but I can look for one... I am also trying the idea of petitlou60
Thank you for this help

Hello,
the following if you are with UEFI bios
From linux you can mount EFI filesystem
cd EFI/Microsoft/boot
check size of bootmgfw.efi if it is > 1Mo , update has replaced copy of dcsboot.efi with this module
make this changes
remove bootmgfw_ms.vc
rename bootmgfw.efi bootmgfw_ms.vc
copy EFI/Veracrypt/dcsboot.efi bootmgfw.efi
(i am not sure of syntax of this copy rename on linux)
best regards
Hello!
Thank you a lot.
I only can boot on Legacy mode since my Windows system is broken: I have to boot on a live USB drive.
But in general I am with a UEFI bios, so I tried what you proposedm and since I entered the first line (CD EFI/Microsoft/boot), it answers "No such file or directory". Should I try the next steps whereas this error?
Thanks again!

yes before cd you need to be root and use command like
mount /dev/sda1 /mnt , then cd /mnt
where sda1 is id of EFI partition (généraly the first on the disk)
Thank you again!
I followed the process, that worked until last step: when I try to copy dcsboot from Veracrypt directory, it answers there is no such file or directory to copy...
May I find it elsewhere?

Sorry, it was a mistake of mine: that works!
I can boot on my system disk and decrypt it forever! Please tell users not to use Veracrypt with Windows and uefi boot.
Thanks a lot to all of you!

Windows +UEFI can be encrypted by veracrypt but windows update may updaae bootmgfw.efi
last relessase 1.24 update 6 has an automatic correction for this.
When system is not enccypted veracrypt directory does not exist in EFI
i suppose you have an HP or ACER PC these does not respect uefi spécifications and only rename of bootmgfw.efi is needed for properly boot, else they attempt to boot in windows mode
