I'm working on a Dell Latitude E5430. Recently I booted pcbsd from USB using this file:



PCBSD10.1.1-RELEASE-01-31-2015-x64-DVD-USB_0.iso


But I guess I did something wrong. I was trying to install Solaris earlier, and I think I accidentally changed disk setup somehow.



Now, if I try to start up, I get the message



invalid partition table!


and fail to start.



If I press F12 and enter the boot option screen, I can choose:



UEFI BOOT:UEFI: Hard Drive


This way, I can start the system.



If I change the BIOS setup and disable the internal HDD, I get:



PXE-E61: Media test failure, check table
PXE-M0F: Exiting Broadcom PXE ROM.
No Boot Device Found. Press any key to reboot the machine


Does anyone know how to solve this?

          Might be a missing "active partition" within DOS Partition Table, just ran into that with E5450 and Linux -- fire up fdisk and check/set.

            The F12 boot option screen seems to indicate that the disk is currently configured as UEFI-bootable. That is, it has a GPT partition table and an ESP boot partition.



            If the system is now configured to attempt legacy-style booting, it would try to find a legacy-style boot code (Master Boot Record, or MBR for short) in the first block of the hard disk. A GPT-partitioned disk will have a "protective MBR": a MBR-compatible first block that basically says: "this disk is completely used by a strange partition type that is not bootable using legacy-style methods".



            If your system is now configured to attempt a legacy-style boot off the hard disk, that would explain the invalid partition table message: the GPT-partitioned disk is indeed invalid for legacy-style booting.



            Press F2 at boot to enter Setup for your system, and find the Boot List Option setting. If it is set to Legacy, that might explain the problem: change it to UEFI and then look at the Boot Sequence options again: they might look slightly different now. Make sure that the hard disk is still selected and try again. If you see the name of your OS/bootloader in the UEFI boot sequence list, pick it instead.
