I've been running DSM_5.2-5644 for over a year. I didn't notice anything unusual before it failed to boot, error Syslinux 6.03 EDDBoot error. I went into the BIOS and verified that the USB stick is the first boot device, and I tried different HDD as the second boot device, but that didn't change the error. I'm guessing I have to reinstall XPEnology again. I searched the forum but didn't see anything about boot errors after XPEnology is up and running, just during the install phase. Thanks to the community for years of successful XPEnology fun! As always, any help / advice is very much appreciated.
EDIT: sorry I didn't realize my hardware info isn't in my signature:
Samsung 16GB BAR USB 3.0 Flash Drive (MUF-16BA/AM)
ASRock N3150DC-ITX
