Does the system BIOS recognize the hard drive (F2 at powerup)?  If so, is the hard drive listed before the network boot (PXE) in the boot sequence?

*Edit, both "family control" should be "family controller".

It does recognize the hard drive.  The boot options says

1.UEIF IP4 realtek pcie FE family control

2.UEIF IP6 realtek pcie FE family control

3. OS

4. Boot Manager.

If that is not what you were talkin about then i dunno.  This is what was listed in the BIOS under the BOOT tab.

Any idea what changed this?  Like i said it was fine one morning then that night the  "Start pxe over ipv4" thing happened.  What id like to know is what caused it.  All i installed was a game, the was the only change and bam, weird stuff going on.

Assuming what you want to do is boot from the hard drive, "OS" needs to be listed before the two Ethernet controllers.

Unknown.  If the system has UEFI, that's a work in progress - as are GPT drives.

I have had this message several times in the past two days. Same PC, Dell Inspiron 3520, also bought in December 2012. It runs fine, and I have had no other issues with it. I was able to manually turn it off and turn it back on each time and after one or two tries it (slowly) loaded normally. I thought maybe it had to do with having an ethernet cable plugged in before start up, as that is the only change from usual, and by taking out the cable and restarting it worked. But that seemed like a bizarre reason, so I found this forum by looking up the same "Start PXE over IPv4". Did you figure out a resolution to this? I am not PC-savvy at all, so I read the replies but could not understand the rest of the thread :/ I hoped maybe you could let me know how things worked out with yours. Thanks!

What it was doing for me kendrams, is trying to boot out of sequence.  My boot menu looked like this

1.UEIF IP4 realtek pcie FE family control

2.UEIF IP6 realtek pcie FE family control

3. OS

4. Boot Manager.

OS should be number one.  Now i never tried unplugging my net cable to see if that changed anything, since i never used wireless, i started with a cable.  What i did was go into the boot menu(f2 at startup) and just changed OS to #1 and it starts up like it used to.  Nobody was ever able to tell me why it switched things, but it hasnt since i changed it back and the laptop has been running top notch.  Hope that helps you, i know how frustrating this can be.

Thank you!
