Sometimes, usually every other time I boot up the PC its goes through the checks and before the Windows screen I get BOOTMGR.EXE MISSING

Now when I go into the bios I see either my (Newish) Oz Agility HD is missing so first boot device place is empty, OR the drive has moved to the bottom of the list of harddrives in the boot sequence.. I have 4 HD's so it does to 4th.. I then have to go into the advanced settings and move it to the top, save the changes and it boots.. couple days later it starts again!

Any advice???

The first thing I would do is move the boot drive to a different SATA plug. If it still does it I, would guess that the drive is faulty - if not the SATA point on the motherboard is possibly faulty - put one of your other drives onto the questionable plug and see if it goes missing occasionally.

Has it got a little lithium battery that needs replacing on the motherboard?

My laptop used to forget the settings until I replaced this, there are the same batteries in car key fobs, just soldered in place.

Just run windw repair that should sort it...

Hi,
on the moment that this happens you should enter a windows setup disk and
boot from that disk,
when you are asked to" help with dosPROMPT" go for it

after dos PROMPT type ; cmd enter
and then type fix/MBR enter.

now your PC will make an new Master Boot Record,

Wilfried.
