how to remove DVD ROM from computer?

I am using LG DVD ROM on my desktop computer.
Unfortunately Now there are some problem with it.too large to explain here hardware problem. But the real problem arising at start up of windows 7.
In normal cases as i press CPU button to start computer light on DVD ROM glow for 5 times , a beep sound and after that there is screen asking for which OS you wan to use(Xubuntu 11.04,windows 7).But if that light glow unexpected way then different start up screen appear. A white screen appear with large word CONSISTENT with on it.
I think this is due to problem of DVD ROM. If i remove that then this issue should solved. So finally the thing i want to ask that is
Does it require to make any change in setting of BIOS or computer to remove DVD ROM if no then i am going to unplug it.
I just want to remove this from CPU so that it start up properly. My plan is to remove all cables inserted in DVD ROM and leave it there as it is(don't open bolts). As i have seen there are two cables that connects computer to DVD ROM i will unplug both of them.

Hello vikash123, welcome to the forum,

Just unplugging the drive should be enough to test for problems, let us know how you get on

You should have a sata power cable and a sata data cable connected to it if it is sata DVD. If it is a PCI it will have a long ribbon and a 4 pin power cable. Whichever it is, just disconnect them. As for bios, No changes should really be necessary. If you have it in the boot order, remove it, and make sure your HD with the OS is listed first.

I doubt that you will have to make changes in the BIOS as it wont pick up the DVDRom when it is disconnected. and should boot to the HDD like normal.

Pooch is correct, as usual.
