Missing Operating System

Featured Replies

Got this error today morning, have no idea why :( I`ve tried formating and preparing the flash usb many times more, nothing helped

What can be the reason of the problem?

Assuming it booted at one time in the past, Your bios no longer thinks the flash drive is the boot drive, therefore it is attempting to boot from one of your hard-disk drives and the one it is attempting to use has no operating system... or, in its words, the operating system is "Missing"

But the bios recognizes it well, and I can still apply emulation on this (Hard Disk/Forced FDD/CD ROM). When I try to boot from a hard disk I get no message and system hangs on black screen...

Did you successfully boot that flash drive on that motherboard with unRaid software before? 

 

Or are you just setting it up for the first time?

It`s been working long time untill today. I tried it few second ago on my pc's motherboard and it booted propertly.

I`m so confused right now...

You might try setting the USB to version 1 in the bios.... at least one other person found his flash drive failing to boot on USB 2.

 

Could be a symptom of the flash drive going bad on you.

I`ve already tried setting USB 2.0 to USB 1.1 and changing the physical socket for usb stick. Nothing works...

I called my friend to bring me his usb stick, and I will try this one. Maybe that`s a problem with the stick itself. But there is one more problem if it`s true: I`ll have to pay for pro license once more cause the UID will change... :(

Looking through the chain, my guess is that you forgot how you originally formatted the stick / bios setting combination to get your server motherboard to boot. 

 

The stick is not bad since you could boot up on another PC.  And since your server bios is seeing the stick, then you do not have bad USB ports.  The issue is that the server bios is not interpreting the partition on the USB stick correctly in which to boot.

 

Use the HP tool to reformat the stick as it typically is the best place to start, and set the BIOS, then experiment with either FAT32 or FAT until you get the server to boot.

I`ve tried all the combinations with FAT32 and FAT (tried every cluster size). But I`ve never heard about the HP Tool. What is it?

 

EDIT: But if it works on my computer then it should work also on my server, shouldn`t it? Sth must be set wrong in bios, but I tried all the combinations...

 

P.S. I remember when I was booting it first time (some months ago) I had the same issue cause I hadn`t had the label set to "UNRAID", but now it is and the same problem occurs anyway...

"But if it works on my computer then it should work also on my server, shouldn`t it?"

 

    No.  You no doubt have different BIOS on those systems

 

"I had the same issue cause I hadn`t had the label set to "UNRAID",

 

    Not setting the Label to "UNRAID" will not prevent the booting and loaded the kernel - it will however prevent the Unraid configuration files from loading.

 

HP has moved the USB stick format tool around on their website, but try http://www.pcworld.com/downloads/file/fid,64963-order,1-page,1-c,peripherals/description.html

In addition to this, try using the HP format tool to format the usb drive as a DOS Boot Disk (you will need to point it to DOS boot files - a boot floppy will suffice)  I'm not sure *why* this works, but it's the only way I could get my USB drive to boot on several different motherboards.

I didn't see it mentioned anywhere above, so I'll state it, just in case...  Did you use syslinux on the drive?  It's important, makes it Linux bootable.

I`m so sorry I forgot about you, but my excitement was so big that I`d got it worked, cause I thought I would not make it work and have to commit a suicide :)

 

Thanks for help, many kisses hugs and much love for you all :)
