5/28/2023 0 Comments Remove truecrypt bootloaderAfter an update of your mainboard BIOS, or after major Windows 10 updates, you may experience a boot-loop or bluescreen, where Windows 10 will try to “repair” your Windows 10 installation over and over, without succeeding. The following applies if you encrypted your whole system drive / partition using VeraCrypt. What you experience is, that the UEFI boot entry for VeraCrypt is gone. Problems with VeraCrypt and Windows 10 bootloader However, there are some problems connected to VeraCrypt and UEFI / Windows 10’s update mechanism / bootloader handling. Being an OpenSource tool based on the original TrueCrypt, it has been significantly improved over its predesessor and is widespread in the community. If the encrypted HDD is inserted, but the USB IS NOT - the PC boots the original system (and it is possible to mount my encrypted HDD inside this system), but when you PLUG IN the USB, it boots the encrypted one.If you want to work with Full Disk Encryption (FDE), plus pre-boot authentication and you don’t want to use Windows BitLocker for some reason, it is likely you will end up with VeraCrypt. in my case there was no need using hide and unhide options, as well as the makeactive option. So I installed a regular GRUB using WinGrub, extracted my TrueCrypt MBR using HDHacker, and saved the *.dat file (with my MBR record) to a USB pendrive (as tc.dat). For this I was looking for something that could be installed on a USB stick and would let me boot from the caddy AND would be compatible with the encrypted drive. So after turning on the PC was asking for a TrueCrypt password, or to hit ESC (hitting ESC would boot from the caddy HDD).īut I wanted to let the original HDD remain in its original place, and just insert the caddy in case I want to use my own system. Temporarily I installed the encrypted HDD in the SATA bay, and the original one in the CD caddy. The default boot HDD is the one in the SATA bay and that's it. The problem was that the BIOS wouldn't see the second HDD and won't let me choose from which to boot. The additional HDD is a 500GB WD SATA drive with default partitions created for Windows 7 (during the installation Win7 created a 100MB primary partition, and set the rest of space as a big Windows partition). I replaced the CD-ROM with a IDE caddy and installed a second HDD over there with my very own Windows 7 encrypted with TrueCrypt with pre-boot auth. This is my working laptop, and I wanted to run my private OS from time to time from another HDD. ** Can grub4dos boot Windows 7 or must it chainload to a Windows boot loader?Īstanasto, thank u very much your thread was helpful big big time!!įor weeks now I have been trying to make my configuration to work, and today it did thanks to this threadīasically I have a Dell Inspiron 1525 with a SATA HDD installed (Win 7).* Can I put the truecrypt mbr file in on the 100MB Windows partition or do I need to create a new boot partition for grub4dos to find the truecrypt boot loader on?.Is grub4dos the right tool or could/should I use grub/grub2?.configure second option to chainload to the TrueCrypt mbr file which performs PBA and then boots the second Windows 7.configure first option to boot first Windows 7**.configure grub4dos to have a menu behaving as described above.Boot a live CD and save the TrueCrypt MBR to a file*.Use TrueCrypt to encrypt the second operating system (192GB), letting it replace the bootloader in the MBR with it's own.I believe grub4dos (or perhaps just grub?) can help me get around this but I'm not sure how to proceed. According to the warnings in the installer, it will then require pre-boot authentication regardless of whether the target operating system is on an encrypted partition or not. If I simply install TrueCrypt while booted into the second operating system and configure it to encrypt only the 192GB partition, it will replace the bootloader on the MBR. I have no qualms about blowing away and reinstalling / repartitioning things if needed. 192GB Windows 7 primary partition with OS installed.32GB Windows 7 primary partition with OS installed.100MB Windows 7 primary partition (system/boot).booting from removable devices will be disabled in BIOS in the final configuration - solution should not rely on keys or bootloaders on USB drives except those needed during initial install.The second install should be on a partition encrypted with TrueCrypt using pre-boot authentiction.The first installation should be set to boot automatically as the default in whatever boot loader I am using and require NO pre-boot authentication.However, my end goal involves the following: I currently have two Windows 7 installations using the Windows boot loader/menu and a shared boot partition. I'm trying to build my laptop to multiboot two installations of Windows 7.
