Prerequisites

Before installing Citrix UniconOS (formerly eLux 7) Dual Boot, ensure the following:

• You have local administrator rights on the device.
• The device runs Windows 11 in UEFI boot mode. Legacy BIOS is not supported.

• The Windows system partition (C:) has enough free space for UniconOS plus a Windows reserve:

  Item	Size
  Minimum free space required (default)	36 GB
  Reserved for Windows	20 GB
  UniconOS partition, default size	16 GB
  UniconOS partition, configurable range	16–64 GB

  If you choose a UniconOS partition larger than the 16 GB default, add the difference to the 20 GB Windows reserve. More free space is recommended.

• You have obtained:
  • The UniconOS Dual Boot installer (UniconOSDualBootSetup.exe).
  • The UniconOS Dual Boot image (.zip/.dd) for the matching UniconOS release.

  Contact your Citrix representative for access and guidance.

Disk encryption (BitLocker)

The installer detects the Windows system drive’s BitLocker state automatically — no manual step is required. If BitLocker protection is active, the installer suspends it for the single install and resumes it automatically afterwards.

Note:

As a precaution, ensure the 48-digit BitLocker recovery key is escrowed before you roll out.

Do not change the firmware Secure Boot setting while BitLocker is active without first escrowing the key. A Secure Boot toggle changes the measurements BitLocker validates and triggers a recovery-key prompt — this is a Windows/firmware behavior, independent of UniconOS.
