February 2, 201412 yr Had an unexpected power outage today and now it will not boot. Had been running well for a number of years. Replaced a drive last week that had failed, powered up and everything worked great until this afternoon. I normally run as a headless server, but moved the box to a monitor/keyboard. Checked Bios settings--still set to boot from a flash drive. Upon powering up, I get a message on the screen "Reboot or Select Proper Boot Device or Insert Boot Media and press a key". Maybe something happened with the USB or config file? The Unraid USB is readable with my laptop. Server is (or was) a registered version running 6x2 TB WD Black drives. My Unraid server has HTPC content that I'd like to get back up and running. Any help is REALLY appreciated. Total newbie when it comes to Linux... Thanks Chad
February 2, 201412 yr Could be just the flash. They tend to die unexpectedly, I've had 2 or 3 go bad. None for unRaid so far but I know that day will come. Try it in your PC or Mac... That will narrow it down.
February 2, 201412 yr Author More info: the LED on the USB Flash Drive does Light up a few times upon power on. Could I have a bad config file on the USB drive? I made copy of the contents of the USB drive--but not sure if that would help troubleshoot (or if I am supposed to post it)? Thanks Chad
February 2, 201412 yr Do you have a recent backup of the flash that you could replace files from? Maybe the file system got corrupt or one particular file. I messed one up recently by shutting down the server abruptly. Lucky it was on a new build with no real configure so I just re-formated and replaced the file system the flash and all was well.
February 2, 201412 yr Author Does it make sense to just reinstall Unraid on the flashdrive? I have my drives labeled--so I know which one is the Parity drive vs. data drives. If so, should I upgrade to 5.0? If anyone can point me in the right direction, I'd really appreciate it. I am very nervous about losing all of this data, so I don't want to do anything that brings me past the point of no return. Any other ideas/suggestions for the recovery (or links)? Thanks again for the assistance. Really great forum/community.... Chad
February 2, 201412 yr Backup your key file. You might just see if you can boot a fresh copy of unRAID 5 from a different flash drive. It won't know about your disks and it won't have a key so you won't be able to actually get it going completely, but it will let you troubleshoot whether you can boot from flash or not. Maybe try a different USB port. You might also just try chkdsk on the old flash and rerun make_bootable on it.
February 2, 201412 yr Author Thank you for the help....unfortunately no go. I ran chkdsk on the USB flashdrive. All good. Reran makebootbale.exe Still nothing. I then download a new version of unraid to another usb. Went through installation and still no go. I then put the original USB flashdrive in another computer (desktop PC). Everything booted fine and I got to the tower login prompt. So, I am down to a motherboard/USB loading problem. Nothing wrong with the flashdrive.
February 2, 201412 yr Shutdown and restart your unRAID box. Check the BIOS on bootup. (varies, but hold down F10, F12, F2 or Delete key to access BIOS) Make sure 'USB' is in the Boot Order. Might be called 'USB-HDD' in your BIOS.
February 2, 201412 yr Author BIOS is set to boot from Removable Drive (same setting that has worked the past few years). I think there is something wrong with the motherboard chipset--it won't do anything and the same Unraid USB drive boots in my other desktop computer without issue. Thanks
February 2, 201412 yr The BIOS entry should be more specific to the USB drive. If you attach 2 drives from different vendors they should appear different in BIOS.
February 3, 201412 yr Author THANK YOU. Your post triggered me to re-look at the BIOS settings. Somehow it changed during the power outage. All is well again after a simple reconfig of the BIOS

All is well again after a simple reconfig of the BIOS If your motherboard is several years old, you should consider replacing the mother board battery. That battery provides the power for your BIOS CMOS to store your settings.
