Have you tried to enter the BIOS and look whether the harddrive is chosen as first bootable drive? It might be the CMOS backup battery which fails and therefore settings are lost.

No, I haven't tried that, but thanks for a tip. Once I will try I will keep posted. Thanks

Maybe this can help: https://archivedforum2.beoworld.org/forums/p/22108/182861.aspx#182861 MM

Short update: Once it's turn on, you can heard that the hdd plates are started spinning with clicking (probably hdd faulty) and message came up on the screen as Disk Boot Failure, insert system disk and press Enter. I tried to go to the Bios, but not sure which key on the keyboard should I press, and I tried already F8, F12, F10 but none of them are giving me access to BIOS. Thanks

Thanks for that, will keep you posted once tested.

I have tested it, looks like hdd is faulty. There is no problem to get a replacement hdd (as in previous link) using adapter to convert from ide to sata, but I have no way of getting software of the Beomedia. All I found online was BeoPlayer, but not sure if anyone of you has a recovery copy of the system. Thanks

You will not find the software on-line because B&O just added it to the recovery partition. You then go into the recovery via the BIOS. However as your disk apparently has totally failed you will need to get an disk image from another Beomedia 1 Login to view image

I'm hoping that someone has a disk image for spare from Beomedia 1. Thanks
