Which boot device to choose?

"Hello Pititemel

The first option (P0: WDC WD5000BPVT-80HXZT1) is what you want. This is the Hard drive where all of your data is stored.

The other option is your DVD drive. This option might come up if you leave a DVD or CD in the drive and restart the computer.

If you have very important data (sons pictures since he was born ) Once you have the computer booting back into Windows please make a backup to an external hard drive. If you don't have one please buy one.

I hope this helps."
