Windows won't boot without a dvd drive installed.

[TheySt0leMyName]

Can anyone help me out?
I've just taken my dvd drive out ready for installing water cooling in a week or so but my pc is refusing to boot without it.
It boots up until the windows loading screen then just flashes blue and resets but with the dvd drive hooked back up it boots fine.


Does anyone have any ideas how to sort this out?
Even with the dvd drive in bios is set to ignore it as a boot drive and boot from my ssd as the primary drive.


I've got an Asus P8Z77-V board and it's Win7 64bit ultimate.

Here's a vid to help show the problem.

Try repairing the installation.

You've got a boot override set to a DVD RW there, remove that? Or reset the CMOS.

That's what it sets its self to when the drive it attached.
With it disconnected this is the boot override and it still refuses to load properly.

Did you reset the bios to defaults without the drive plugged in?

I've sorted it.
It turns out the top set of sata 6 ports don't show up in bios as bootable and that's where I had the drives plugged in to. Cheers for the help guys, I can't believe I missed that one.
