something weird happened

[bvsbutthd101]

I was on my computer just browsing the web and my computer went to blue screen and restarted out of nowhere. When it restarted my computer said the BOOTMGR was missing. It turned out it was trying to boot from data drive which doesn't have OS on it. So I had make it boot from my SSD.

Any reason why it would randomly switch from booting from my SSD to HDD out of nowhere?

Was your system overclocked? Specs please. Are you running dual boot Operating systems?

start by testing ram, then get everest and check out temps, then hdtune for the drive, if no problems there, perhaps os but it wont switch boot order like that for nothing? did you lose power? or did the lights flicker?

Here's what I think:

If you have two hard drives in your system, is it possible that you installed windows on the second drive? If that's the case, its possible that windows still wrote its master boot record to your first hard drive. This means that any problem with your first "unused" drive will cause windows to stop booting. The first drive may have died, or just become disconnected/unplugged somehow - recheck all your connections.

If you don't have two hard drives, it could mean that the blue screen, possibly caused by a bad overclock or driver fault, caused a problem with windows as well. Meaning your data is more likely intact, but windows will not boot due to corruption. If this is the case, we'd need to know which version of windows you're using to help you further (In a nutshell though: Windows XP -> Fixmbr, Windows 7 -> restore point or use bootsect.exe)

Further information would be a good start though

My system is overclocked, and my HDD doesn't have an OS on it, just games and apps.
Ran memtest, passed 5 times with no errors, ran LinX 20 times everything maxed, passed with no errors, Lights never flickered, just went to blue screen, and restarted, I dont think it was a power failure, I was only browsing the web, not even playing any games. So no load was being put on. Never happened while playing games either.

hows temps, in particular mobo temps? check vbatt voltage as well.

CPU: 27-29c
MOBO: 29-30c

Please read my last post...

You have both a SSD and a HDD, two drives. Its possible the MBR was on the HDD, even if it didn't contain any OS files...

This is the reason why I disconnect ALL hard drives when installing Windows 7, except the boot drive (ie. SSD). After the install is totally finished, I reconnect them.

Otherwise, Windows will put crap needed to boot on other drives, which is what CMeta is suggesting.

it is possible, i guess. so far ive seen it put the swap on other drives and or partitions. which is not bad. but the boot thingie? hmmmm
