What dell venue 8 pro do you have?
do you have TPM enabled in bios?
You should get a TPM pop message about over-writing the bios security files..
Have to push Down Volume to accept
TPM is were the encryption/bitlocker key is stored.
You need to do three things:
1. Backup
2. Remove hidden recovery partition
3. Install win10 off USB thumbdrive
Create a pc Image using windows, create your recovery drive, copy the recovery partition to it, then delete the partition off tablet.
Right click start control panel/system and security/file history
Turn off bitlocker, then reinstall windows from recovery drive (this is to remove any corruption that may be causing upgrade to fail), then attach the win10 USB thumbdrive, navigate to the "setup" on thumbdrive, and run it. Set tablet to "never" sleep or turn off screen, follow installation prompts. Upgrade takes approx. an hour. Be sure battery is fully charged. During win10 upgrade, be sure to check for updates.
To turn off bitlocker, pull up charms (right screen swipe), settings/PC info (device encryption setting at bottom):

Press Volume Down button right after Power On to enter Bios
My settings
Boot tab > Secure Boot and Fast Boot disabled
security tab > PTT > TPM enabled
in regards to - either way same results
Control Panel > Recovery > Create a Recovery Drive
Thanks.
Just to confirm that I understand what you suggested I would like to know
1) as Windows 10 needs secure boot why it shoud be disabled?
2) Will fast boot hinder upgrade. In my laptop upgrade went smooth with both secure boot and fast boot enabled.
3) before starting upgrade TPM should be enabled. Am I correct?
