**mace** Posted December 30, 2019 Report post Posted December 30, 2019 (edited) Hi all, hope you can assist me with this issue I have been racking my brains on. I have a task sequence (not MDT) that works on most laptops but just not on the dell. I have an inclination it is to do with the the BIOS/UEFI. The task sequence completes successfully however after the last reboot i get no bootable device found. In BIOS i cannot see a hard disk either. Has anyone had any experience with these dells? EDIT: Sorry forgot to mention it is a windows 10 build. Edited December 30, 2019 by **mace** Quote Share this post Link to post Share on other sites More sharing options...
