Edit - found reference to the bit that is set, but need to find how to reset it. It is intended for other efi type partitions like a vendor recovery so users would not damage a vendor recovery. If HP is setting it on the efi partition it is wrong. Bug is not really related to current issue.

Quote from UEFI spec:
Partition creators may prevent UEFI firmware from examining and using a specific partition by setting bit 1 of the Partition Attributes (see 5.3.3) which will exclude the partition as a potential ESP.
