Boot Manager missing?

[dud]

I currently have an HTPC with a Haswell i5 CPU running Win 7 pro. Something unexpected has been happening ... I sometimes get the error message "Boot Manager is missing" upon boot attempt. After numerous boot attempts I checked the BIOS and found that I had the DVD drive set as the first boot drive so I changed it to the SSD. Now the machine boots just fine ... or did the two times I tried it. My question is this: Even with a boot sequence with an empty DVD drive as the first device, shouldn't the system automatically attempt to boot from the second drive (SSD)? I set the system up about three months ago and except for a few hiccups ... it has been running very well with few problems. It has been booting just fine with the previously set sequence and was just wondering why things changed.

Thank you ...

Depends on the BIOS, and how it would assign drives.
That "Boot Manager is missing" just means that the drives were "moved", and the boot loader couldn't find what it was looking to find, so it can't boot.

I had a similar issue with 7 not seeing the bootloader when I built my first uefi machine using a legacy boot. I was seeing boot loops that would vary in the amount of times it would cycle before deciding to load 7. Once I wiped everything out, reformatted the drive and came back with UEFI it worked fine.

I would check your storage device integrity. It might be losing sectors, and lost the boot sector or something. (Was this after a Windows Update?)

Or, maybe your CMOS just got changed somehow, and boot order changed.

I checked the integrity of the SSD (a Crucial M500) with their software and it was fine. Heck, the drive only has about 150 hours on it. I believe the latter is probably the problem. I do not use the system all that often but will check the boot sequence the next time I use it.

Thanks ...

If the cmos isn't holding the settings might be time to change the battery.

That is an excellent suggestion. The MB was purchased new from NE just 3 months ago ... but that does not mean the backup battery hasn't gone bad. I believe that I have some spare 2032s sitting around.

Thank you ... I'll report back.
