Ultimately I had to reinstall Windows due to Windows update constantly checking for updates and some necessary software not installing. After that I tried to encrypt with Truecrypt before touching the partitions and this time it passed pretest and I was able to do system encryption. Since I hadn't at that point touched the partitions I can only surmise that Truecrypt was sensing system corruption that I didn't know about. Any idea what? It's kind of strange having corruption on such a new install of windows. I just wanted to do an update. Thanks for the help.
I need to encrypt my replacement system with a fresh install of 8.1 with truecrypt but I am unable to. Initially after the reboot it failed pretest (even though windows booted) and I had to revert. I was using AES encryption. The only thing I could find (outside of making sure to select AES and turn off secure boot) was that this was a known issue on HP machines and I have an HP Pavillion Elite HPE-250f. This was on a veracrypt forum and they said that the issue had been fixed. I made matters worse by marking the Windows partition as active. After that on reboot Truecrypt couldn't boot the OS at all and I had to use my install disk to fix the boot loader. Then I tried veracrypt and it just sat at loading. Again I had to fix the boot loader. The only thing I could definitively read to do was to delete a 100 mb partition. On my install there are 2 partitions that are ~350-450 mb. Is that why I can't use truecrypt or veracrypt? If so which one do I remove? One looks like it might be in use by the recovery partition. I'll attach a screenshot from disk manager. I don't have any data on this drive so I am not against a reinstall if necessary but I want to keep the recovery partition on it. I think that this computer is too old for secure boot because I'm not finding it in the BIOS settings.
I don't have the option of removing the 450 mb partition in computer management. My guess is because it's marked as an active recovery partition. I can remove it from the install disk but it is marked as OEM reserved and I got a warning that if I remove it might not be able to boot into the recovery image. I'd rather keep that so if someone else has any suggestions I would be appreciative. I am using Windows 8.1.
