Good day, dear support!
I am having an issue with my HP MFP E52645 printer.
It has error 99.09.66: "Missing boot."
I replaced the hard drive with a WD Red SATA SSD 500GB and tried to boot from a USB drive where I keep the firmware, but when I restarted the printer, it showed error 99.09.60: "Unsupported disk."
Can anyone help me? Can I use a laptop HDD?
